Every little help counts, so do not hesitate! .. contents:: Contribution links :depth: 2 .. _submitplugin: Submit a plugin, co-develop pytest ---------------------------------- Pytest development of the core, some plugins and support code happens in repositories living under: - `the pytest-dev github organisation `_ - `the pytest-dev bitbucket team `_ All pytest-dev Contributors team members have write access to all contained repositories. pytest core and plugins are generally developed using `pull requests`_ to respective repositories. You can submit your plugin by subscribing to the `pytest-dev mail list `_ and writing a mail pointing to your existing pytest plugin repository which must have the following: - PyPI presence with a ``setup.py`` that contains a license, ``pytest-`` prefixed, version number, authors, short and long description. - a ``tox.ini`` for running tests using `tox `_. - a ``README.txt`` describing how to use the plugin and on which platforms it runs. - a ``LICENSE.txt`` file or equivalent containing the licensing information, with matching info in ``setup.py``. - an issue tracker unless you rather want to use the core ``pytest`` issue tracker. If no contributor strongly objects and two agree, the repo will be transferred to the ``pytest-dev`` organisation and you'll become a member of the ``pytest-dev Contributors`` team, with commit rights to all projects. We recommend that each plugin has at least three people who have the right to release to pypi. .. _reportbugs: Report bugs ----------- Report bugs for pytest at https://github.com/pytest-dev/pytest/issues If you are reporting a bug, please include: * Your operating system name and version. * Any details about your local setup that might be helpful in troubleshooting, specifically Python interpreter version, installed libraries and pytest version. * Detailed steps to reproduce the bug. If you can write a demonstration test that currently fails but should pass (xfail), that is a very useful commit to make as well, even if you can't find how to fix the bug yet. .. _submitfeedback: Submit feedback for developers ------------------------------ Do you like pytest? Share some love on Twitter or in your blog posts! We'd also like to hear about your propositions and suggestions. Feel free to `submit them as issues `__ and: * Set the "kind" to "enhancement" or "proposal" so that we can quickly find about them. * Explain in detail how they should work. * Keep the scope as narrow as possible. This will make it easier to implement. * If you have required skills and/or knowledge, we are very happy for :ref:`pull requests `. .. _fixbugs: Fix bugs -------- Look through the GitHub issues for bugs. Here is sample filter you can use: https://github.com/pytest-dev/pytest/labels/bug :ref:`Talk ` to developers to find out how you can fix specific bugs. Don't forget to check the issue trackers of your favourite plugins, too! .. _writeplugins: Implement features ------------------ Look through the GitHub issues for enhancements. Here is sample filter you can use: https://github.com/pytest-dev/pytest/labels/enhancement :ref:`Talk ` to developers to find out how you can implement specific features. Write documentation ------------------- pytest could always use more documentation. What exactly is needed? * More complementary documentation. Have you perhaps found something unclear? * Documentation translations. We currently have only English. * Docstrings. There can never be too many of them. * Blog posts, articles and such -- they're all very appreciated. You can also edit documentation files directly in the Github web interface without needing to make a fork and local copy. This can be convenient for small fixes. .. _`pull requests`: .. _pull-requests: Preparing Pull Requests on GitHub --------------------------------- .. note:: What is a "pull request"? It informs project's core developers about the changes you want to review and merge. Pull requests are stored on `GitHub servers `_. Once you send pull request, we can discuss it's potential modifications and even add more commits to it later on. There's an excellent tutorial on how Pull Requests work in the `GitHub Help Center `_, but here is a simple overview: #. Fork the `pytest GitHub repository `__. It's fine to use ``pytest`` as your fork repository name because it will live under your user. #. Clone your fork locally using `git `_ and create a branch:: $ git clone git@github.com:YOUR_GITHUB_USERNAME/pytest.git $ cd pytest # now, to fix a bug create your own branch off "master": $ git checkout -b your-bugfix-branch-name master # or to instead add a feature create your own branch off "features": $ git checkout -b your-feature-branch-name features Given we have "major.minor.micro" version numbers, bugfixes will usually be released in micro releases whereas features will be released in minor releases and incompatible changes in major releases. If you need some help with Git, follow this quick start guide: https://git.wiki.kernel.org/index.php/QuickStart #. Install tox Tox is used to run all the tests and will automatically setup virtualenvs to run the tests in. (will implicitly use http://www.virtualenv.org/en/latest/):: $ pip install tox #. Run all the tests You need to have Python 2.7 and 3.5 available in your system. Now running tests is as simple as issuing this command:: $ python runtox.py -e py27,py35,flakes This command will run tests via the "tox" tool against Python 2.7 and 3.5 and also perform "flakes" coding-style checks. ``runtox.py`` is a thin wrapper around ``tox`` which installs from a development package index where newer (not yet released to pypi) versions of dependencies (especially ``py``) might be present. #. You can now edit your local working copy. You can now make the changes you want and run the tests again as necessary. To run tests on py27 and pass options to pytest (e.g. enter pdb on failure) to pytest you can do:: $ python runtox.py -e py27 -- --pdb or to only run tests in a particular test module on py35:: $ python runtox.py -e py35 -- testing/test_config.py #. Commit and push once your tests pass and you are happy with your change(s):: $ git commit -a -m "" $ git push -u Make sure you add a CHANGELOG message, and add yourself to AUTHORS. If you are unsure about either of these steps, submit your pull request and we'll help you fix it up. #. Finally, submit a pull request through the GitHub website using this data:: head-fork: YOUR_GITHUB_USERNAME/pytest compare: your-branch-name base-fork: pytest-dev/pytest base: master # if it's a bugfix base: feature # if it's a feature pytest-2.8.7/CHANGELOG0000664000175000017500000030203212651247335014640 0ustar ronnyronny000000000000002.8.7 ---------- - fix #1338: use predictable object resolution for monkeypatch 2.8.6 ----- - fix #1259: allow for double nodeids in junitxml, this was a regression failing plugins combinations like pytest-pep8 + pytest-flakes - Workaround for exception that occurs in pyreadline when using ``--pdb`` with standard I/O capture enabled.

Thanks Suor for the report and Bruno Oliveira / Tom Viner for the PR. - fix #331: don't collect tests if their failure cannot be reported correctly e.g. they are a callable instance of a class. - fix #1133: fixed internal error when filtering tracebacks where one entry belongs to a file which is no longer available. Thanks Bruno Oliveira for the PR. - enhancement made to highlight in red the name of the failing tests so they stand out in the output. Thanks Gabriel Reis for the PR. - add more talks to the documentation - extend documentation on the --ignore cli option - use pytest-runner for setuptools integration - minor fixes for interaction with OS X El Capitan system integrity protection (thanks Florian) 2.8.2 ----- - fix #1085: proper handling of encoding errors when passing encoded byte strings to pytest.parametrize in Python 2. Thanks Themanwithoutaplan for the report and Bruno Oliveira for the PR. - fix #1087: handling SystemError when passing empty byte strings to pytest.parametrize in Python 3. Thanks Paul Kehrer for the report and Bruno Oliveira for the PR. - fix #995: fixed internal error when filtering tracebacks where one entry was generated by an exec() statement. Thanks Daniel Hahler, Ashley C Straw, Philippe Gauthier and Pavel Savchenko for contributing and Bruno Oliveira for the PR. - fix #1100 and #1057: errors when using autouse fixtures and doctest modules. Thanks Sergey B Kirpichev and Vital Kudzelka for contributing and Bruno Oliveira for the PR. 2.8.1 ----- - fix #1034: Add missing nodeid on pytest_logwarning call in addhook. Thanks Simon Gomizelj for the PR. - 'deprecated_call' is now only satisfied with a DeprecationWarning or PendingDeprecationWarning. Before 2.8.0, it accepted any warning, and 2.8.0 made it accept only DeprecationWarning (but not PendingDeprecationWarning). Thanks Alex Gaynor for the issue and Eric Hunsberger for the PR. - fix issue #1073: avoid calling __getattr__ on potential plugin objects. This fixes an incompatibility with pytest-django. Thanks Andreas Pelme, Bruno Oliveira and Ronny Pfannschmidt for contributing and Holger Krekel for the fix. - Fix issue #704: handle versionconflict during plugin loading more gracefully. Thanks Bruno Oliveira for the PR. - Fix issue #1064: ""--junitxml" regression when used with the "pytest-xdist" plugin, with test reports being assigned to the wrong tests. Thanks Daniel Grunwald for the report and Bruno Oliveira for the PR. - (experimental) adapt more SEMVER style versioning and change meaning of master branch in git repo: "master" branch now keeps the bugfixes, changes aimed for micro releases. "features" branch will only be be released with minor or major pytest releases. - Fix issue #766 by removing documentation references to distutils. Thanks Russel Winder. - Fix issue #1030: now byte-strings are escaped to produce item node ids to make them always serializable. Thanks Andy Freeland for the report and Bruno Oliveira for the PR. - Python 2: if unicode parametrized values are convertible to ascii, their ascii representation is used for the node id. - Fix issue #411: Add __eq__ method to assertion comparison example. Thanks Ben Webb. - fix issue 877: properly handle assertion explanations with non-ascii repr Thanks Mathieu Agopian for the report and Ronny Pfannschmidt for the PR. - fix issue 1029: transform errors when writing cache values into pytest-warnings 2.8.0 ----------------------------- - new ``--lf`` and ``-ff`` options to run only the last failing tests or "failing tests first" from the last run. This functionality is provided through porting the formerly external pytest-cache plugin into pytest core. BACKWARD INCOMPAT: if you used pytest-cache's functionality to persist data between test runs be aware that we don't serialize sets anymore. Thanks Ronny Pfannschmidt for most of the merging work. - "-r" option now accepts "a" to include all possible reports, similar to passing "fEsxXw" explicitly (isse960). Thanks Abhijeet Kasurde for the PR. - avoid python3.5 deprecation warnings by introducing version specific inspection helpers, thanks Michael Droettboom. - fix issue562: @nose.tools.istest now fully respected. - fix issue934: when string comparison fails and a diff is too large to display without passing -vv, still show a few lines of the diff. Thanks Florian Bruhin for the report and Bruno Oliveira for the PR. - fix issue736: Fix a bug where fixture params would be discarded when combined with parametrization markers. Thanks to Markus Unterwaditzer for the PR. - fix issue710: introduce ALLOW_UNICODE doctest option: when enabled, the ``u`` prefix is stripped from unicode strings in expected doctest output. This allows doctests which use unicode to run in Python 2 and 3 unchanged. Thanks Jason R. Coombs for the report and Bruno Oliveira for the PR. - parametrize now also generates meaningful test IDs for enum, regex and class objects (as opposed to class instances). Thanks to Florian Bruhin for the PR. - Add 'warns' to assert that warnings are thrown (like 'raises'). Thanks to Eric Hunsberger for the PR. - Fix issue683: Do not apply an already applied mark. Thanks ojake for the PR. - Deal with capturing failures better so fewer exceptions get lost to /dev/null. Thanks David Szotten for the PR. - fix issue730: deprecate and warn about the --genscript option. Thanks Ronny Pfannschmidt for the report and Christian Pommranz for the PR. - fix issue751: multiple parametrize with ids bug if it parametrizes class with two or more test methods. Thanks Sergey Chipiga for reporting and Jan Bednarik for PR. - fix issue82: avoid loading conftest files from setup.cfg/pytest.ini/tox.ini files and upwards by default (--confcutdir can still be set to override this). Thanks Bruno Oliveira for the PR. - fix issue768: docstrings found in python modules were not setting up session fixtures. Thanks Jason R. Coombs for reporting and Bruno Oliveira for the PR. - added `tmpdir_factory`, a session-scoped fixture that can be used to create directories under the base temporary directory. Previously this object was installed as a `_tmpdirhandler` attribute of the `config` object, but now it is part of the official API and using `config._tmpdirhandler` is deprecated. Thanks Bruno Oliveira for the PR. - fix issue808: pytest's internal assertion rewrite hook now implements the optional PEP302 get_data API so tests can access data files next to them. Thanks xmo-odoo for request and example and Bruno Oliveira for the PR. - rootdir and inifile are now displayed during usage errors to help users diagnose problems such as unexpected ini files which add unknown options being picked up by pytest. Thanks to Pavel Savchenko for bringing the problem to attention in #821 and Bruno Oliveira for the PR. - Summary bar now is colored yellow for warning situations such as: all tests either were skipped or xpass/xfailed, or no tests were run at all (this is a partial fix for issue500). - fix issue812: pytest now exits with status code 5 in situations where no tests were run at all, such as the directory given in the command line does not contain any tests or as result of a command line option filters all out all tests (-k for example). Thanks Eric Siegerman (issue812) and Bruno Oliveira for the PR. - Summary bar now is colored yellow for warning situations such as: all tests either were skipped or xpass/xfailed, or no tests were run at all (related to issue500). Thanks Eric Siegerman. - New `testpaths` ini option: list of directories to search for tests when executing pytest from the root directory. This can be used to speed up test collection when a project has well specified directories for tests, being usually more practical than configuring norecursedirs for all directories that do not contain tests. Thanks to Adrian for idea (#694) and Bruno Oliveira for the PR. - fix issue713: JUnit XML reports for doctest failures. Thanks Punyashloka Biswal. - fix issue970: internal pytest warnings now appear as "pytest-warnings" in the terminal instead of "warnings", so it is clear for users that those warnings are from pytest and not from the builtin "warnings" module. Thanks Bruno Oliveira. - Include setup and teardown in junitxml test durations. Thanks Janne Vanhala. - fix issue735: assertion failures on debug versions of Python 3.4+ - new option ``--import-mode`` to allow to change test module importing behaviour to append to sys.path instead of prepending. This better allows to run test modules against installated versions of a package even if the package under test has the same import root. In this example:: testing/__init__.py testing/test_pkg_under_test.py pkg_under_test/ the tests will run against the installed version of pkg_under_test when ``--import-mode=append`` is used whereas by default they would always pick up the local version. Thanks Holger Krekel. - pytester: add method ``TmpTestdir.delete_loaded_modules()``, and call it from ``inline_run()`` to allow temporary modules to be reloaded. Thanks Eduardo Schettino. - internally refactor pluginmanager API and code so that there is a clear distinction between a pytest-agnostic rather simple pluginmanager and the PytestPluginManager which adds a lot of behaviour, among it handling of the local conftest files. In terms of documented methods this is a backward compatible change but it might still break 3rd party plugins which relied on details like especially the pluginmanager.add_shutdown() API. Thanks Holger Krekel. - pluginmanagement: introduce ``pytest.hookimpl`` and ``pytest.hookspec`` decorators for setting impl/spec specific parameters. This substitutes the previous now deprecated use of ``pytest.mark`` which is meant to contain markers for test functions only. - write/refine docs for "writing plugins" which now have their own page and are separate from the "using/installing plugins`` page. - fix issue732: properly unregister plugins from any hook calling sites allowing to have temporary plugins during test execution. - deprecate and warn about ``__multicall__`` argument in hook implementations. Use the ``hookwrapper`` mechanism instead already introduced with pytest-2.7. - speed up pytest's own test suite considerably by using inprocess tests by default (testrun can be modified with --runpytest=subprocess to create subprocesses in many places instead). The main APIs to run pytest in a test is "runpytest()" or "runpytest_subprocess" and "runpytest_inprocess" if you need a particular way of running the test. In all cases you get back a RunResult but the inprocess one will also have a "reprec" attribute with the recorded events/reports. - fix monkeypatch.setattr("x.y", raising=False) to actually not raise if "y" is not a pre-existing attribute. Thanks Florian Bruhin. - fix issue741: make running output from testdir.run copy/pasteable Thanks Bruno Oliveira. - add a new ``--noconftest`` argument which ignores all ``conftest.py`` files. - add ``file`` and ``line`` attributes to JUnit-XML output. - fix issue890: changed extension of all documentation files from ``txt`` to ``rst``. Thanks to Abhijeet for the PR. - fix issue714: add ability to apply indirect=True parameter on particular argnames. Thanks Elizaveta239. - fix issue890: changed extension of all documentation files from ``txt`` to ``rst``. Thanks to Abhijeet for the PR. - fix issue957: "# doctest: SKIP" option will now register doctests as SKIPPED rather than PASSED. Thanks Thomas Grainger for the report and Bruno Oliveira for the PR. - issue951: add new record_xml_property fixture, that supports logging additional information on xml output. Thanks David Diaz for the PR. - issue949: paths after normal options (for example `-s`, `-v`, etc) are now properly used to discover `rootdir` and `ini` files. Thanks Peter Lauri for the report and Bruno Oliveira for the PR. 2.7.3 (compared to 2.7.2) ----------------------------- - Allow 'dev', 'rc', or other non-integer version strings in `importorskip`. Thanks to Eric Hunsberger for the PR. - fix issue856: consider --color parameter in all outputs (for example --fixtures). Thanks Barney Gale for the report and Bruno Oliveira for the PR. - fix issue855: passing str objects as `plugins` argument to pytest.main is now interpreted as a module name to be imported and registered as a plugin, instead of silently having no effect. Thanks xmo-odoo for the report and Bruno Oliveira for the PR. - fix issue744: fix for ast.Call changes in Python 3.5+. Thanks Guido van Rossum, Matthias Bussonnier, Stefan Zimmermann and Thomas Kluyver. - fix issue842: applying markers in classes no longer propagate this markers to superclasses which also have markers. Thanks xmo-odoo for the report and Bruno Oliveira for the PR. - preserve warning functions after call to pytest.deprecated_call. Thanks Pieter Mulder for PR. - fix issue854: autouse yield_fixtures defined as class members of unittest.TestCase subclasses now work as expected. Thannks xmo-odoo for the report and Bruno Oliveira for the PR. - fix issue833: --fixtures now shows all fixtures of collected test files, instead of just the fixtures declared on the first one. Thanks Florian Bruhin for reporting and Bruno Oliveira for the PR. - fix issue863: skipped tests now report the correct reason when a skip/xfail condition is met when using multiple markers. Thanks Raphael Pierzina for reporting and Bruno Oliveira for the PR. - optimized tmpdir fixture initialization, which should make test sessions faster (specially when using pytest-xdist). The only visible effect is that now pytest uses a subdirectory in the $TEMP directory for all directories created by this fixture (defaults to $TEMP/pytest-$USER). Thanks Bruno Oliveira for the PR. 2.7.2 (compared to 2.7.1) ----------------------------- - fix issue767: pytest.raises value attribute does not contain the exception instance on Python 2.6. Thanks Eric Siegerman for providing the test case and Bruno Oliveira for PR. - Automatically create directory for junitxml and results log. Thanks Aron Curzon. - fix issue713: JUnit XML reports for doctest failures. Thanks Punyashloka Biswal. - fix issue735: assertion failures on debug versions of Python 3.4+ Thanks Benjamin Peterson. - fix issue114: skipif marker reports to internal skipping plugin; Thanks Floris Bruynooghe for reporting and Bruno Oliveira for the PR. - fix issue748: unittest.SkipTest reports to internal pytest unittest plugin. Thanks Thomas De Schampheleire for reporting and Bruno Oliveira for the PR. - fix issue718: failed to create representation of sets containing unsortable elements in python 2. Thanks Edison Gustavo Muenz. - fix issue756, fix issue752 (and similar issues): depend on py-1.4.29 which has a refined algorithm for traceback generation. 2.7.1 (compared to 2.7.0) ----------------------------- - fix issue731: do not get confused by the braces which may be present and unbalanced in an object's repr while collapsing False explanations. Thanks Carl Meyer for the report and test case. - fix issue553: properly handling inspect.getsourcelines failures in FixtureLookupError which would lead to to an internal error, obfuscating the original problem. Thanks talljosh for initial diagnose/patch and Bruno Oliveira for final patch. - fix issue660: properly report scope-mismatch-access errors independently from ordering of fixture arguments. Also avoid the pytest internal traceback which does not provide information to the user. Thanks Holger Krekel. - streamlined and documented release process. Also all versions (in setup.py and documentation generation) are now read from _pytest/__init__.py. Thanks Holger Krekel. - fixed docs to remove the notion that yield-fixtures are experimental. They are here to stay :) Thanks Bruno Oliveira. - Support building wheels by using environment markers for the requirements. Thanks Ionel Maries Cristian. - fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing when tests raised SystemExit. Thanks Holger Krekel. - reintroduced _pytest fixture of the pytester plugin which is used at least by pytest-xdist. 2.7.0 (compared to 2.6.4) ----------------------------- - fix issue435: make reload() work when assert rewriting is active. Thanks Daniel Hahler. - fix issue616: conftest.py files and their contained fixutres are now properly considered for visibility, independently from the exact current working directory and test arguments that are used. Many thanks to Eric Siegerman and his PR235 which contains systematic tests for conftest visibility and now passes. This change also introduces the concept of a ``rootdir`` which is printed as a new pytest header and documented in the pytest customize web page. - change reporting of "diverted" tests, i.e. tests that are collected in one file but actually come from another (e.g. when tests in a test class come from a base class in a different file). We now show the nodeid and indicate via a postfix the other file. - add ability to set command line options by environment variable PYTEST_ADDOPTS. - added documentation on the new pytest-dev teams on bitbucket and github. See https://pytest.org/latest/contributing.html . Thanks to Anatoly for pushing and initial work on this. - fix issue650: new option ``--docttest-ignore-import-errors`` which will turn import errors in doctests into skips. Thanks Charles Cloud for the complete PR. - fix issue655: work around different ways that cause python2/3 to leak sys.exc_info into fixtures/tests causing failures in 3rd party code - fix issue615: assertion re-writing did not correctly escape % signs when formatting boolean operations, which tripped over mixing booleans with modulo operators. Thanks to Tom Viner for the report, triaging and fix. - implement issue351: add ability to specify parametrize ids as a callable to generate custom test ids. Thanks Brianna Laugher for the idea and implementation. - introduce and document new hookwrapper mechanism useful for plugins which want to wrap the execution of certain hooks for their purposes. This supersedes the undocumented ``__multicall__`` protocol which pytest itself and some external plugins use. Note that pytest-2.8 is scheduled to drop supporting the old ``__multicall__`` and only support the hookwrapper protocol. - majorly speed up invocation of plugin hooks - use hookwrapper mechanism in builtin pytest plugins. - add a doctest ini option for doctest flags, thanks Holger Peters. - add note to docs that if you want to mark a parameter and the parameter is a callable, you also need to pass in a reason to disambiguate it from the "decorator" case. Thanks Tom Viner. - "python_classes" and "python_functions" options now support glob-patterns for test discovery, as discussed in issue600. Thanks Ldiary Translations. - allow to override parametrized fixtures with non-parametrized ones and vice versa (bubenkoff). - fix issue463: raise specific error for 'parameterize' misspelling (pfctdayelise). - On failure, the ``sys.last_value``, ``sys.last_type`` and ``sys.last_traceback`` are set, so that a user can inspect the error via postmortem debugging (almarklein). 2.6.4 ---------- - Improve assertion failure reporting on iterables, by using ndiff and pprint. - removed outdated japanese docs from source tree. - docs for "pytest_addhooks" hook. Thanks Bruno Oliveira. - updated plugin index docs. Thanks Bruno Oliveira. - fix issue557: with "-k" we only allow the old style "-" for negation at the beginning of strings and even that is deprecated. Use "not" instead. This should allow to pick parametrized tests where "-" appeared in the parameter. - fix issue604: Escape % character in the assertion message. - fix issue620: add explanation in the --genscript target about what the binary blob means. Thanks Dinu Gherman. - fix issue614: fixed pastebin support. - fix issue620: add explanation in the --genscript target about what the binary blob means. Thanks Dinu Gherman. - fix issue614: fixed pastebin support. 2.6.3 ----------- - fix issue575: xunit-xml was reporting collection errors as failures instead of errors, thanks Oleg Sinyavskiy. - fix issue582: fix setuptools example, thanks Laszlo Papp and Ronny Pfannschmidt. - Fix infinite recursion bug when pickling capture.EncodedFile, thanks Uwe Schmitt. - fix issue589: fix bad interaction with numpy and others when showing exceptions. Check for precise "maximum recursion depth exceed" exception instead of presuming any RuntimeError is that one (implemented in py dep). Thanks Charles Cloud for analysing the issue. - fix conftest related fixture visibility issue: when running with a CWD outside a test package pytest would get fixture discovery wrong. Thanks to Wolfgang Schnerring for figuring out a reproducable example. - Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the timeout when interactively entering pdb). Thanks Wolfgang Schnerring. - check xfail/skip also with non-python function test items. Thanks Floris Bruynooghe. 2.6.2 ----------- - Added function pytest.freeze_includes(), which makes it easy to embed pytest into executables using tools like cx_freeze. See docs for examples and rationale. Thanks Bruno Oliveira. - Improve assertion rewriting cache invalidation precision. - fixed issue561: adapt autouse fixture example for python3. - fixed issue453: assertion rewriting issue with __repr__ containing "\n{", "\n}" and "\n~". - fix issue560: correctly display code if an "else:" or "finally:" is followed by statements on the same line. - Fix example in monkeypatch documentation, thanks t-8ch. - fix issue572: correct tmpdir doc example for python3. - Do not mark as universal wheel because Python 2.6 is different from other builds due to the extra argparse dependency. Fixes issue566. Thanks sontek. - Implement issue549: user-provided assertion messages now no longer replace the py.test introspection message but are shown in addition to them. 2.6.1 ----------------------------------- - No longer show line numbers in the --verbose output, the output is now purely the nodeid. The line number is still shown in failure reports. Thanks Floris Bruynooghe. - fix issue437 where assertion rewriting could cause pytest-xdist slaves to collect different tests. Thanks Bruno Oliveira. - fix issue555: add "errors" attribute to capture-streams to satisfy some distutils and possibly other code accessing sys.stdout.errors. - fix issue547 capsys/capfd also work when output capturing ("-s") is disabled. - address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via an optional "raises=EXC" argument where EXC can be a single exception or a tuple of exception classes. Thanks David Mohr for the complete PR. - fix integration of pytest with unittest.mock.patch decorator when it uses the "new" argument. Thanks Nicolas Delaby for test and PR. - fix issue with detecting conftest files if the arguments contain "::" node id specifications (copy pasted from "-v" output) - fix issue544 by only removing "@NUM" at the end of "::" separated parts and if the part has an ".py" extension - don't use py.std import helper, rather import things directly. Thanks Bruno Oliveira. 2.6 ----------------------------------- - Cache exceptions from fixtures according to their scope (issue 467). - fix issue537: Avoid importing old assertion reinterpretation code by default. - fix issue364: shorten and enhance tracebacks representation by default. The new "--tb=auto" option (default) will only display long tracebacks for the first and last entry. You can get the old behaviour of printing all entries as long entries with "--tb=long". Also short entries by default are now printed very similarly to "--tb=native" ones. - fix issue514: teach assertion reinterpretation about private class attributes - change -v output to include full node IDs of tests. Users can copy a node ID from a test run, including line number, and use it as a positional argument in order to run only a single test. - fix issue 475: fail early and comprehensible if calling pytest.raises with wrong exception type. - fix issue516: tell in getting-started about current dependencies. - cleanup setup.py a bit and specify supported versions. Thanks Jurko Gospodnetic for the PR. - change XPASS colour to yellow rather then red when tests are run with -v. - fix issue473: work around mock putting an unbound method into a class dict when double-patching. - fix issue498: if a fixture finalizer fails, make sure that the fixture is still invalidated. - fix issue453: the result of the pytest_assertrepr_compare hook now gets it's newlines escaped so that format_exception does not blow up. - internal new warning system: pytest will now produce warnings when it detects oddities in your test collection or execution. Warnings are ultimately sent to a new pytest_logwarning hook which is currently only implemented by the terminal plugin which displays warnings in the summary line and shows more details when -rw (report on warnings) is specified. - change skips into warnings for test classes with an __init__ and callables in test modules which look like a test but are not functions. - fix issue436: improved finding of initial conftest files from command line arguments by using the result of parse_known_args rather than the previous flaky heuristics. Thanks Marc Abramowitz for tests and initial fixing approaches in this area. - fix issue #479: properly handle nose/unittest(2) SkipTest exceptions during collection/loading of test modules. Thanks to Marc Schlaich for the complete PR. - fix issue490: include pytest_load_initial_conftests in documentation and improve docstring. - fix issue472: clarify that ``pytest.config.getvalue()`` cannot work if it's triggered ahead of command line parsing. - merge PR123: improved integration with mock.patch decorator on tests. - fix issue412: messing with stdout/stderr FD-level streams is now captured without crashes. - fix issue483: trial/py33 works now properly. Thanks Daniel Grana for PR. - improve example for pytest integration with "python setup.py test" which now has a generic "-a" or "--pytest-args" option where you can pass additional options as a quoted string. Thanks Trevor Bekolay. - simplified internal capturing mechanism and made it more robust against tests or setups changing FD1/FD2, also better integrated now with pytest.pdb() in single tests. - improvements to pytest's own test-suite leakage detection, courtesy of PRs from Marc Abramowitz - fix issue492: avoid leak in test_writeorg. Thanks Marc Abramowitz. - fix issue493: don't run tests in doc directory with ``python setup.py test`` (use tox -e doctesting for that) - fix issue486: better reporting and handling of early conftest loading failures - some cleanup and simplification of internal conftest handling. - work a bit harder to break reference cycles when catching exceptions. Thanks Jurko Gospodnetic. - fix issue443: fix skip examples to use proper comparison. Thanks Alex Groenholm. - support nose-style ``__test__`` attribute on modules, classes and functions, including unittest-style Classes. If set to False, the test will not be collected. - fix issue512: show "" for arguments which might not be set in monkeypatch plugin. Improves output in documentation. 2.5.2 ----------------------------------- - fix issue409 -- better interoperate with cx_freeze by not trying to import from collections.abc which causes problems for py27/cx_freeze. Thanks Wolfgang L. for reporting and tracking it down. - fixed docs and code to use "pytest" instead of "py.test" almost everywhere. Thanks Jurko Gospodnetic for the complete PR. - fix issue425: mention at end of "py.test -h" that --markers and --fixtures work according to specified test path (or current dir) - fix issue413: exceptions with unicode attributes are now printed correctly also on python2 and with pytest-xdist runs. (the fix requires py-1.4.20) - copy, cleanup and integrate py.io capture from pylib 1.4.20.dev2 (rev 13d9af95547e) - address issue416: clarify docs as to conftest.py loading semantics - fix issue429: comparing byte strings with non-ascii chars in assert expressions now work better. Thanks Floris Bruynooghe. - make capfd/capsys.capture private, its unused and shouldnt be exposed 2.5.1 ----------------------------------- - merge new documentation styling PR from Tobias Bieniek. - fix issue403: allow parametrize of multiple same-name functions within a collection node. Thanks Andreas Kloeckner and Alex Gaynor for reporting and analysis. - Allow parameterized fixtures to specify the ID of the parameters by adding an ids argument to pytest.fixture() and pytest.yield_fixture(). Thanks Floris Bruynooghe. - fix issue404 by always using the binary xml escape in the junitxml plugin. Thanks Ronny Pfannschmidt. - fix issue407: fix addoption docstring to point to argparse instead of optparse. Thanks Daniel D. Wright. 2.5.0 ----------------------------------- - dropped python2.5 from automated release testing of pytest itself which means it's probably going to break soon (but still works with this release we believe). - simplified and fixed implementation for calling finalizers when parametrized fixtures or function arguments are involved. finalization is now performed lazily at setup time instead of in the "teardown phase". While this might sound odd at first, it helps to ensure that we are correctly handling setup/teardown even in complex code. User-level code should not be affected unless it's implementing the pytest_runtest_teardown hook and expecting certain fixture instances are torn down within (very unlikely and would have been unreliable anyway). - PR90: add --color=yes|no|auto option to force terminal coloring mode ("auto" is default). Thanks Marc Abramowitz. - fix issue319 - correctly show unicode in assertion errors. Many thanks to Floris Bruynooghe for the complete PR. Also means we depend on py>=1.4.19 now. - fix issue396 - correctly sort and finalize class-scoped parametrized tests independently from number of methods on the class. - refix issue323 in a better way -- parametrization should now never cause Runtime Recursion errors because the underlying algorithm for re-ordering tests per-scope/per-fixture is not recursive anymore (it was tail-call recursive before which could lead to problems for more than >966 non-function scoped parameters). - fix issue290 - there is preliminary support now for parametrizing with repeated same values (sometimes useful to to test if calling a second time works as with the first time). - close issue240 - document precisely how pytest module importing works, discuss the two common test directory layouts, and how it interacts with PEP420-namespace packages. - fix issue246 fix finalizer order to be LIFO on independent fixtures depending on a parametrized higher-than-function scoped fixture. (was quite some effort so please bear with the complexity of this sentence :) Thanks Ralph Schmitt for the precise failure example. - fix issue244 by implementing special index for parameters to only use indices for paramentrized test ids - fix issue287 by running all finalizers but saving the exception from the first failing finalizer and re-raising it so teardown will still have failed. We reraise the first failing exception because it might be the cause for other finalizers to fail. - fix ordering when mock.patch or other standard decorator-wrappings are used with test methods. This fixues issue346 and should help with random "xdist" collection failures. Thanks to Ronny Pfannschmidt and Donald Stufft for helping to isolate it. - fix issue357 - special case "-k" expressions to allow for filtering with simple strings that are not valid python expressions. Examples: "-k 1.3" matches all tests parametrized with 1.3. "-k None" filters all tests that have "None" in their name and conversely "-k 'not None'". Previously these examples would raise syntax errors. - fix issue384 by removing the trial support code since the unittest compat enhancements allow trial to handle it on its own - don't hide an ImportError when importing a plugin produces one. fixes issue375. - fix issue275 - allow usefixtures and autouse fixtures for running doctest text files. - fix issue380 by making --resultlog only rely on longrepr instead of the "reprcrash" attribute which only exists sometimes. - address issue122: allow @pytest.fixture(params=iterator) by exploding into a list early on. - fix pexpect-3.0 compatibility for pytest's own tests. (fixes issue386) - allow nested parametrize-value markers, thanks James Lan for the PR. - fix unicode handling with new monkeypatch.setattr(import_path, value) API. Thanks Rob Dennis. Fixes issue371. - fix unicode handling with junitxml, fixes issue368. - In assertion rewriting mode on Python 2, fix the detection of coding cookies. See issue #330. - make "--runxfail" turn imperative pytest.xfail calls into no ops (it already did neutralize pytest.mark.xfail markers) - refine pytest / pkg_resources interactions: The AssertionRewritingHook PEP302 compliant loader now registers itself with setuptools/pkg_resources properly so that the pkg_resources.resource_stream method works properly. Fixes issue366. Thanks for the investigations and full PR to Jason R. Coombs. - pytestconfig fixture is now session-scoped as it is the same object during the whole test run. Fixes issue370. - avoid one surprising case of marker malfunction/confusion:: @pytest.mark.some(lambda arg: ...) def test_function(): would not work correctly because pytest assumes @pytest.mark.some gets a function to be decorated already. We now at least detect if this arg is an lambda and thus the example will work. Thanks Alex Gaynor for bringing it up. - xfail a test on pypy that checks wrong encoding/ascii (pypy does not error out). fixes issue385. - internally make varnames() deal with classes's __init__, although it's not needed by pytest itself atm. Also fix caching. Fixes issue376. - fix issue221 - handle importing of namespace-package with no __init__.py properly. - refactor internal FixtureRequest handling to avoid monkeypatching. One of the positive user-facing effects is that the "request" object can now be used in closures. - fixed version comparison in pytest.importskip(modname, minverstring) - fix issue377 by clarifying in the nose-compat docs that pytest does not duplicate the unittest-API into the "plain" namespace. - fix verbose reporting for @mock'd test functions v2.4.2 ----------------------------------- - on Windows require colorama and a newer py lib so that py.io.TerminalWriter() now uses colorama instead of its own ctypes hacks. (fixes issue365) thanks Paul Moore for bringing it up. - fix "-k" matching of tests where "repr" and "attr" and other names would cause wrong matches because of an internal implementation quirk (don't ask) which is now properly implemented. fixes issue345. - avoid tmpdir fixture to create too long filenames especially when parametrization is used (issue354) - fix pytest-pep8 and pytest-flakes / pytest interactions (collection names in mark plugin was assuming an item always has a function which is not true for those plugins etc.) Thanks Andi Zeidler. - introduce node.get_marker/node.add_marker API for plugins like pytest-pep8 and pytest-flakes to avoid the messy details of the node.keywords pseudo-dicts. Adapted docs. - remove attempt to "dup" stdout at startup as it's icky. the normal capturing should catch enough possibilities of tests messing up standard FDs. - add pluginmanager.do_configure(config) as a link to config.do_configure() for plugin-compatibility v2.4.1 ----------------------------------- - When using parser.addoption() unicode arguments to the "type" keyword should also be converted to the respective types. thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362) - fix dotted filename completion when using argcomplete thanks Anthon van der Neuth. (fixes issue361) - fix regression when a 1-tuple ("arg",) is used for specifying parametrization (the values of the parametrization were passed nested in a tuple). Thanks Donald Stufft. - merge doc typo fixes, thanks Andy Dirnberger v2.4 ----------------------------------- known incompatibilities: - if calling --genscript from python2.7 or above, you only get a standalone script which works on python2.7 or above. Use Python2.6 to also get a python2.5 compatible version. - all xunit-style teardown methods (nose-style, pytest-style, unittest-style) will not be called if the corresponding setup method failed, see issue322 below. - the pytest_plugin_unregister hook wasn't ever properly called and there is no known implementation of the hook - so it got removed. - pytest.fixture-decorated functions cannot be generators (i.e. use yield) anymore. This change might be reversed in 2.4.1 if it causes unforeseen real-life issues. However, you can always write and return an inner function/generator and change the fixture consumer to iterate over the returned generator. This change was done in lieu of the new ``pytest.yield_fixture`` decorator, see below. new features: - experimentally introduce a new ``pytest.yield_fixture`` decorator which accepts exactly the same parameters as pytest.fixture but mandates a ``yield`` statement instead of a ``return statement`` from fixture functions. This allows direct integration with "with-style" context managers in fixture functions and generally avoids registering of finalization callbacks in favour of treating the "after-yield" as teardown code. Thanks Andreas Pelme, Vladimir Keleshev, Floris Bruynooghe, Ronny Pfannschmidt and many others for discussions. - allow boolean expression directly with skipif/xfail if a "reason" is also specified. Rework skipping documentation to recommend "condition as booleans" because it prevents surprises when importing markers between modules. Specifying conditions as strings will remain fully supported. - reporting: color the last line red or green depending if failures/errors occurred or everything passed. thanks Christian Theunert. - make "import pdb ; pdb.set_trace()" work natively wrt capturing (no "-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut. - fix issue181: --pdb now also works on collect errors (and on internal errors) . This was implemented by a slight internal refactoring and the introduction of a new hook ``pytest_exception_interact`` hook (see next item). - fix issue341: introduce new experimental hook for IDEs/terminals to intercept debugging: ``pytest_exception_interact(node, call, report)``. - new monkeypatch.setattr() variant to provide a shorter invocation for patching out classes/functions from modules: monkeypatch.setattr("requests.get", myfunc) will replace the "get" function of the "requests" module with ``myfunc``. - fix issue322: tearDownClass is not run if setUpClass failed. Thanks Mathieu Agopian for the initial fix. Also make all of pytest/nose finalizer mimick the same generic behaviour: if a setupX exists and fails, don't run teardownX. This internally introduces a new method "node.addfinalizer()" helper which can only be called during the setup phase of a node. - simplify pytest.mark.parametrize() signature: allow to pass a CSV-separated string to specify argnames. For example: ``pytest.mark.parametrize("input,expected", [(1,2), (2,3)])`` works as well as the previous: ``pytest.mark.parametrize(("input", "expected"), ...)``. - add support for setUpModule/tearDownModule detection, thanks Brian Okken. - integrate tab-completion on options through use of "argcomplete". Thanks Anthon van der Neut for the PR. - change option names to be hyphen-separated long options but keep the old spelling backward compatible. py.test -h will only show the hyphenated version, for example "--collect-only" but "--collectonly" will remain valid as well (for backward-compat reasons). Many thanks to Anthon van der Neut for the implementation and to Hynek Schlawack for pushing us. - fix issue 308 - allow to mark/xfail/skip individual parameter sets when parametrizing. Thanks Brianna Laugher. - call new experimental pytest_load_initial_conftests hook to allow 3rd party plugins to do something before a conftest is loaded. Bug fixes: - fix issue358 - capturing options are now parsed more properly by using a new parser.parse_known_args method. - pytest now uses argparse instead of optparse (thanks Anthon) which means that "argparse" is added as a dependency if installing into python2.6 environments or below. - fix issue333: fix a case of bad unittest/pytest hook interaction. - PR27: correctly handle nose.SkipTest during collection. Thanks Antonio Cuni, Ronny Pfannschmidt. - fix issue355: junitxml puts name="pytest" attribute to testsuite tag. - fix issue336: autouse fixture in plugins should work again. - fix issue279: improve object comparisons on assertion failure for standard datatypes and recognise collections.abc. Thanks to Brianna Laugher and Mathieu Agopian. - fix issue317: assertion rewriter support for the is_package method - fix issue335: document py.code.ExceptionInfo() object returned from pytest.raises(), thanks Mathieu Agopian. - remove implicit distribute_setup support from setup.py. - fix issue305: ignore any problems when writing pyc files. - SO-17664702: call fixture finalizers even if the fixture function partially failed (finalizers would not always be called before) - fix issue320 - fix class scope for fixtures when mixed with module-level functions. Thanks Anatloy Bubenkoff. - you can specify "-q" or "-qq" to get different levels of "quieter" reporting (thanks Katarzyna Jachim) - fix issue300 - Fix order of conftest loading when starting py.test in a subdirectory. - fix issue323 - sorting of many module-scoped arg parametrizations - make sessionfinish hooks execute with the same cwd-context as at session start (helps fix plugin behaviour which write output files with relative path such as pytest-cov) - fix issue316 - properly reference collection hooks in docs - fix issue 306 - cleanup of -k/-m options to only match markers/test names/keywords respectively. Thanks Wouter van Ackooy. - improved doctest counting for doctests in python modules -- files without any doctest items will not show up anymore and doctest examples are counted as separate test items. thanks Danilo Bellini. - fix issue245 by depending on the released py-1.4.14 which fixes py.io.dupfile to work with files with no mode. Thanks Jason R. Coombs. - fix junitxml generation when test output contains control characters, addressing issue267, thanks Jaap Broekhuizen - fix issue338: honor --tb style for setup/teardown errors as well. Thanks Maho. - fix issue307 - use yaml.safe_load in example, thanks Mark Eichin. - better parametrize error messages, thanks Brianna Laugher - pytest_terminal_summary(terminalreporter) hooks can now use ".section(title)" and ".line(msg)" methods to print extra information at the end of a test run. v2.3.5 ----------------------------------- - fix issue169: respect --tb=style with setup/teardown errors as well. - never consider a fixture function for test function collection - allow re-running of test items / helps to fix pytest-reruntests plugin and also help to keep less fixture/resource references alive - put captured stdout/stderr into junitxml output even for passing tests (thanks Adam Goucher) - Issue 265 - integrate nose setup/teardown with setupstate so it doesnt try to teardown if it did not setup - issue 271 - dont write junitxml on slave nodes - Issue 274 - dont try to show full doctest example when doctest does not know the example location - issue 280 - disable assertion rewriting on buggy CPython 2.6.0 - inject "getfixture()" helper to retrieve fixtures from doctests, thanks Andreas Zeidler - issue 259 - when assertion rewriting, be consistent with the default source encoding of ASCII on Python 2 - issue 251 - report a skip instead of ignoring classes with init - issue250 unicode/str mixes in parametrization names and values now works - issue257, assertion-triggered compilation of source ending in a comment line doesn't blow up in python2.5 (fixed through py>=1.4.13.dev6) - fix --genscript option to generate standalone scripts that also work with python3.3 (importer ordering) - issue171 - in assertion rewriting, show the repr of some global variables - fix option help for "-k" - move long description of distribution into README.rst - improve docstring for metafunc.parametrize() - fix bug where using capsys with pytest.set_trace() in a test function would break when looking at capsys.readouterr() - allow to specify prefixes starting with "_" when customizing python_functions test discovery. (thanks Graham Horler) - improve PYTEST_DEBUG tracing output by puting extra data on a new lines with additional indent - ensure OutcomeExceptions like skip/fail have initialized exception attributes - issue 260 - don't use nose special setup on plain unittest cases - fix issue134 - print the collect errors that prevent running specified test items - fix issue266 - accept unicode in MarkEvaluator expressions v2.3.4 ----------------------------------- - yielded test functions will now have autouse-fixtures active but cannot accept fixtures as funcargs - it's anyway recommended to rather use the post-2.0 parametrize features instead of yield, see: http://pytest.org/latest/example/parametrize.html - fix autouse-issue where autouse-fixtures would not be discovered if defined in a a/conftest.py file and tests in a/tests/test_some.py - fix issue226 - LIFO ordering for fixture teardowns - fix issue224 - invocations with >256 char arguments now work - fix issue91 - add/discuss package/directory level setups in example - allow to dynamically define markers via item.keywords[...]=assignment integrating with "-m" option - make "-k" accept an expressions the same as with "-m" so that one can write: -k "name1 or name2" etc. This is a slight incompatibility if you used special syntax like "TestClass.test_method" which you now need to write as -k "TestClass and test_method" to match a certain method in a certain test class. v2.3.3 ----------------------------------- - fix issue214 - parse modules that contain special objects like e. g. flask's request object which blows up on getattr access if no request is active. thanks Thomas Waldmann. - fix issue213 - allow to parametrize with values like numpy arrays that do not support an __eq__ operator - fix issue215 - split test_python.org into multiple files - fix issue148 - @unittest.skip on classes is now recognized and avoids calling setUpClass/tearDownClass, thanks Pavel Repin - fix issue209 - reintroduce python2.4 support by depending on newer pylib which re-introduced statement-finding for pre-AST interpreters - nose support: only call setup if its a callable, thanks Andrew Taumoefolau - fix issue219 - add py2.4-3.3 classifiers to TROVE list - in tracebacks *,** arg values are now shown next to normal arguments (thanks Manuel Jacob) - fix issue217 - support mock.patch with pytest's fixtures - note that you need either mock-1.0.1 or the python3.3 builtin unittest.mock. - fix issue127 - improve documentation for pytest_addoption() and add a ``config.getoption(name)`` helper function for consistency. v2.3.2 ----------------------------------- - fix issue208 and fix issue29 use new py version to avoid long pauses when printing tracebacks in long modules - fix issue205 - conftests in subdirs customizing pytest_pycollect_makemodule and pytest_pycollect_makeitem now work properly - fix teardown-ordering for parametrized setups - fix issue127 - better documentation for pytest_addoption and related objects. - fix unittest behaviour: TestCase.runtest only called if there are test methods defined - improve trial support: don't collect its empty unittest.TestCase.runTest() method - "python setup.py test" now works with pytest itself - fix/improve internal/packaging related bits: - exception message check of test_nose.py now passes on python33 as well - issue206 - fix test_assertrewrite.py to work when a global PYTHONDONTWRITEBYTECODE=1 is present - add tox.ini to pytest distribution so that ignore-dirs and others config bits are properly distributed for maintainers who run pytest-own tests v2.3.1 ----------------------------------- - fix issue202 - fix regression: using "self" from fixture functions now works as expected (it's the same "self" instance that a test method which uses the fixture sees) - skip pexpect using tests (test_pdb.py mostly) on freebsd* systems due to pexpect not supporting it properly (hanging) - link to web pages from --markers output which provides help for pytest.mark.* usage. v2.3.0 ----------------------------------- - fix issue202 - better automatic names for parametrized test functions - fix issue139 - introduce @pytest.fixture which allows direct scoping and parametrization of funcarg factories. - fix issue198 - conftest fixtures were not found on windows32 in some circumstances with nested directory structures due to path manipulation issues - fix issue193 skip test functions with were parametrized with empty parameter sets - fix python3.3 compat, mostly reporting bits that previously depended on dict ordering - introduce re-ordering of tests by resource and parametrization setup which takes precedence to the usual file-ordering - fix issue185 monkeypatching time.time does not cause pytest to fail - fix issue172 duplicate call of pytest.fixture decoratored setup_module functions - fix junitxml=path construction so that if tests change the current working directory and the path is a relative path it is constructed correctly from the original current working dir. - fix "python setup.py test" example to cause a proper "errno" return - fix issue165 - fix broken doc links and mention stackoverflow for FAQ - catch unicode-issues when writing failure representations to terminal to prevent the whole session from crashing - fix xfail/skip confusion: a skip-mark or an imperative pytest.skip will now take precedence before xfail-markers because we can't determine xfail/xpass status in case of a skip. see also: http://stackoverflow.com/questions/11105828/in-py-test-when-i-explicitly-skip-a-test-that-is-marked-as-xfail-how-can-i-get - always report installed 3rd party plugins in the header of a test run - fix issue160: a failing setup of an xfail-marked tests should be reported as xfail (not xpass) - fix issue128: show captured output when capsys/capfd are used - fix issue179: propperly show the dependency chain of factories - pluginmanager.register(...) now raises ValueError if the plugin has been already registered or the name is taken - fix issue159: improve http://pytest.org/latest/faq.html especially with respect to the "magic" history, also mention pytest-django, trial and unittest integration. - make request.keywords and node.keywords writable. All descendant collection nodes will see keyword values. Keywords are dictionaries containing markers and other info. - fix issue 178: xml binary escapes are now wrapped in py.xml.raw - fix issue 176: correctly catch the builtin AssertionError even when we replaced AssertionError with a subclass on the python level - factory discovery no longer fails with magic global callables that provide no sane __code__ object (mock.call for example) - fix issue 182: testdir.inprocess_run now considers passed plugins - fix issue 188: ensure sys.exc_info is clear on python2 before calling into a test - fix issue 191: add unittest TestCase runTest method support - fix issue 156: monkeypatch correctly handles class level descriptors - reporting refinements: - pytest_report_header now receives a "startdir" so that you can use startdir.bestrelpath(yourpath) to show nice relative path - allow plugins to implement both pytest_report_header and pytest_sessionstart (sessionstart is invoked first). - don't show deselected reason line if there is none - py.test -vv will show all of assert comparisations instead of truncating v2.2.4 ----------------------------------- - fix error message for rewritten assertions involving the % operator - fix issue 126: correctly match all invalid xml characters for junitxml binary escape - fix issue with unittest: now @unittest.expectedFailure markers should be processed correctly (you can also use @pytest.mark markers) - document integration with the extended distribute/setuptools test commands - fix issue 140: propperly get the real functions of bound classmethods for setup/teardown_class - fix issue #141: switch from the deceased paste.pocoo.org to bpaste.net - fix issue #143: call unconfigure/sessionfinish always when configure/sessionstart where called - fix issue #144: better mangle test ids to junitxml classnames - upgrade distribute_setup.py to 0.6.27 v2.2.3 ---------------------------------------- - fix uploaded package to only include neccesary files v2.2.2 ---------------------------------------- - fix issue101: wrong args to unittest.TestCase test function now produce better output - fix issue102: report more useful errors and hints for when a test directory was renamed and some pyc/__pycache__ remain - fix issue106: allow parametrize to be applied multiple times e.g. from module, class and at function level. - fix issue107: actually perform session scope finalization - don't check in parametrize if indirect parameters are funcarg names - add chdir method to monkeypatch funcarg - fix crash resulting from calling monkeypatch undo a second time - fix issue115: make --collectonly robust against early failure (missing files/directories) - "-qq --collectonly" now shows only files and the number of tests in them - "-q --collectonly" now shows test ids - allow adding of attributes to test reports such that it also works with distributed testing (no upgrade of pytest-xdist needed) v2.2.1 ---------------------------------------- - fix issue99 (in pytest and py) internallerrors with resultlog now produce better output - fixed by normalizing pytest_internalerror input arguments. - fix issue97 / traceback issues (in pytest and py) improve traceback output in conjunction with jinja2 and cython which hack tracebacks - fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns": the final test in a test node will now run its teardown directly instead of waiting for the end of the session. Thanks Dave Hunt for the good reporting and feedback. The pytest_runtest_protocol as well as the pytest_runtest_teardown hooks now have "nextitem" available which will be None indicating the end of the test run. - fix collection crash due to unknown-source collected items, thanks to Ralf Schmitt (fixed by depending on a more recent pylib) v2.2.0 ---------------------------------------- - fix issue90: introduce eager tearing down of test items so that teardown function are called earlier. - add an all-powerful metafunc.parametrize function which allows to parametrize test function arguments in multiple steps and therefore from indepdenent plugins and palces. - add a @pytest.mark.parametrize helper which allows to easily call a test function with different argument values - Add examples to the "parametrize" example page, including a quick port of Test scenarios and the new parametrize function and decorator. - introduce registration for "pytest.mark.*" helpers via ini-files or through plugin hooks. Also introduce a "--strict" option which will treat unregistered markers as errors allowing to avoid typos and maintain a well described set of markers for your test suite. See exaples at http://pytest.org/latest/mark.html and its links. - issue50: introduce "-m marker" option to select tests based on markers (this is a stricter and more predictable version of '-k' in that "-m" only matches complete markers and has more obvious rules for and/or semantics. - new feature to help optimizing the speed of your tests: --durations=N option for displaying N slowest test calls and setup/teardown methods. - fix issue87: --pastebin now works with python3 - fix issue89: --pdb with unexpected exceptions in doctest work more sensibly - fix and cleanup pytest's own test suite to not leak FDs - fix issue83: link to generated funcarg list - fix issue74: pyarg module names are now checked against imp.find_module false positives - fix compatibility with twisted/trial-11.1.0 use cases - simplify Node.listchain - simplify junitxml output code by relying on py.xml - add support for skip properties on unittest classes and functions v2.1.3 ---------------------------------------- - fix issue79: assertion rewriting failed on some comparisons in boolops - correctly handle zero length arguments (a la pytest '') - fix issue67 / junitxml now contains correct test durations, thanks ronny - fix issue75 / skipping test failure on jython - fix issue77 / Allow assertrepr_compare hook to apply to a subset of tests v2.1.2 ---------------------------------------- - fix assertion rewriting on files with windows newlines on some Python versions - refine test discovery by package/module name (--pyargs), thanks Florian Mayer - fix issue69 / assertion rewriting fixed on some boolean operations - fix issue68 / packages now work with assertion rewriting - fix issue66: use different assertion rewriting caches when the -O option is passed - don't try assertion rewriting on Jython, use reinterp v2.1.1 ---------------------------------------------- - fix issue64 / pytest.set_trace now works within pytest_generate_tests hooks - fix issue60 / fix error conditions involving the creation of __pycache__ - fix issue63 / assertion rewriting on inserts involving strings containing '%' - fix assertion rewriting on calls with a ** arg - don't cache rewritten modules if bytecode generation is disabled - fix assertion rewriting in read-only directories - fix issue59: provide system-out/err tags for junitxml output - fix issue61: assertion rewriting on boolean operations with 3 or more operands - you can now build a man page with "cd doc ; make man" v2.1.0 ---------------------------------------------- - fix issue53 call nosestyle setup functions with correct ordering - fix issue58 and issue59: new assertion code fixes - merge Benjamin's assertionrewrite branch: now assertions for test modules on python 2.6 and above are done by rewriting the AST and saving the pyc file before the test module is imported. see doc/assert.txt for more info. - fix issue43: improve doctests with better traceback reporting on unexpected exceptions - fix issue47: timing output in junitxml for test cases is now correct - fix issue48: typo in MarkInfo repr leading to exception - fix issue49: avoid confusing error when initizaliation partially fails - fix issue44: env/username expansion for junitxml file path - show releaselevel information in test runs for pypy - reworked doc pages for better navigation and PDF generation - report KeyboardInterrupt even if interrupted during session startup - fix issue 35 - provide PDF doc version and download link from index page v2.0.3 ---------------------------------------------- - fix issue38: nicer tracebacks on calls to hooks, particularly early configure/sessionstart ones - fix missing skip reason/meta information in junitxml files, reported via http://lists.idyll.org/pipermail/testing-in-python/2011-March/003928.html - fix issue34: avoid collection failure with "test" prefixed classes deriving from object. - don't require zlib (and other libs) for genscript plugin without --genscript actually being used. - speed up skips (by not doing a full traceback represenation internally) - fix issue37: avoid invalid characters in junitxml's output v2.0.2 ---------------------------------------------- - tackle issue32 - speed up test runs of very quick test functions by reducing the relative overhead - fix issue30 - extended xfail/skipif handling and improved reporting. If you have a syntax error in your skip/xfail expressions you now get nice error reports. Also you can now access module globals from xfail/skipif expressions so that this for example works now:: import pytest import mymodule @pytest.mark.skipif("mymodule.__version__[0] == "1") def test_function(): pass This will not run the test function if the module's version string does not start with a "1". Note that specifying a string instead of a boolean expressions allows py.test to report meaningful information when summarizing a test run as to what conditions lead to skipping (or xfail-ing) tests. - fix issue28 - setup_method and pytest_generate_tests work together The setup_method fixture method now gets called also for test function invocations generated from the pytest_generate_tests hook. - fix issue27 - collectonly and keyword-selection (-k) now work together Also, if you do "py.test --collectonly -q" you now get a flat list of test ids that you can use to paste to the py.test commandline in order to execute a particular test. - fix issue25 avoid reported problems with --pdb and python3.2/encodings output - fix issue23 - tmpdir argument now works on Python3.2 and WindowsXP Starting with Python3.2 os.symlink may be supported. By requiring a newer py lib version the py.path.local() implementation acknowledges this. - fixed typos in the docs (thanks Victor Garcia, Brianna Laugher) and particular thanks to Laura Creighton who also revieved parts of the documentation. - fix slighly wrong output of verbose progress reporting for classes (thanks Amaury) - more precise (avoiding of) deprecation warnings for node.Class|Function accesses - avoid std unittest assertion helper code in tracebacks (thanks Ronny) v2.0.1 ---------------------------------------------- - refine and unify initial capturing so that it works nicely even if the logging module is used on an early-loaded conftest.py file or plugin. - allow to omit "()" in test ids to allow for uniform test ids as produced by Alfredo's nice pytest.vim plugin. - fix issue12 - show plugin versions with "--version" and "--traceconfig" and also document how to add extra information to reporting test header - fix issue17 (import-* reporting issue on python3) by requiring py>1.4.0 (1.4.1 is going to include it) - fix issue10 (numpy arrays truth checking) by refining assertion interpretation in py lib - fix issue15: make nose compatibility tests compatible with python3 (now that nose-1.0 supports python3) - remove somewhat surprising "same-conftest" detection because it ignores conftest.py when they appear in several subdirs. - improve assertions ("not in"), thanks Floris Bruynooghe - improve behaviour/warnings when running on top of "python -OO" (assertions and docstrings are turned off, leading to potential false positives) - introduce a pytest_cmdline_processargs(args) hook to allow dynamic computation of command line arguments. This fixes a regression because py.test prior to 2.0 allowed to set command line options from conftest.py files which so far pytest-2.0 only allowed from ini-files now. - fix issue7: assert failures in doctest modules. unexpected failures in doctests will not generally show nicer, i.e. within the doctest failing context. - fix issue9: setup/teardown functions for an xfail-marked test will report as xfail if they fail but report as normally passing (not xpassing) if they succeed. This only is true for "direct" setup/teardown invocations because teardown_class/ teardown_module cannot closely relate to a single test. - fix issue14: no logging errors at process exit - refinements to "collecting" output on non-ttys - refine internal plugin registration and --traceconfig output - introduce a mechanism to prevent/unregister plugins from the command line, see http://pytest.org/plugins.html#cmdunregister - activate resultlog plugin by default - fix regression wrt yielded tests which due to the collection-before-running semantics were not setup as with pytest 1.3.4. Note, however, that the recommended and much cleaner way to do test parametraization remains the "pytest_generate_tests" mechanism, see the docs. v2.0.0 ---------------------------------------------- - pytest-2.0 is now its own package and depends on pylib-2.0 - new ability: python -m pytest / python -m pytest.main ability - new python invcation: pytest.main(args, plugins) to load some custom plugins early. - try harder to run unittest test suites in a more compatible manner by deferring setup/teardown semantics to the unittest package. also work harder to run twisted/trial and Django tests which should now basically work by default. - introduce a new way to set config options via ini-style files, by default setup.cfg and tox.ini files are searched. The old ways (certain environment variables, dynamic conftest.py reading is removed). - add a new "-q" option which decreases verbosity and prints a more nose/unittest-style "dot" output. - fix issue135 - marks now work with unittest test cases as well - fix issue126 - introduce py.test.set_trace() to trace execution via PDB during the running of tests even if capturing is ongoing. - fix issue123 - new "python -m py.test" invocation for py.test (requires Python 2.5 or above) - fix issue124 - make reporting more resilient against tests opening files on filedescriptor 1 (stdout). - fix issue109 - sibling conftest.py files will not be loaded. (and Directory collectors cannot be customized anymore from a Directory's conftest.py - this needs to happen at least one level up). - introduce (customizable) assertion failure representations and enhance output on assertion failures for comparisons and other cases (Floris Bruynooghe) - nose-plugin: pass through type-signature failures in setup/teardown functions instead of not calling them (Ed Singleton) - remove py.test.collect.Directory (follows from a major refactoring and simplification of the collection process) - majorly reduce py.test core code, shift function/python testing to own plugin - fix issue88 (finding custom test nodes from command line arg) - refine 'tmpdir' creation, will now create basenames better associated with test names (thanks Ronny) - "xpass" (unexpected pass) tests don't cause exitcode!=0 - fix issue131 / issue60 - importing doctests in __init__ files used as namespace packages - fix issue93 stdout/stderr is captured while importing conftest.py - fix bug: unittest collected functions now also can have "pytestmark" applied at class/module level - add ability to use "class" level for cached_setup helper - fix strangeness: mark.* objects are now immutable, create new instances v1.3.4 ---------------------------------------------- - fix issue111: improve install documentation for windows - fix issue119: fix custom collectability of __init__.py as a module - fix issue116: --doctestmodules work with __init__.py files as well - fix issue115: unify internal exception passthrough/catching/GeneratorExit - fix issue118: new --tb=native for presenting cpython-standard exceptions v1.3.3 ---------------------------------------------- - fix issue113: assertion representation problem with triple-quoted strings (and possibly other cases) - make conftest loading detect that a conftest file with the same content was already loaded, avoids surprises in nested directory structures which can be produced e.g. by Hudson. It probably removes the need to use --confcutdir in most cases. - fix terminal coloring for win32 (thanks Michael Foord for reporting) - fix weirdness: make terminal width detection work on stdout instead of stdin (thanks Armin Ronacher for reporting) - remove trailing whitespace in all py/text distribution files v1.3.2 ---------------------------------------------- New features ++++++++++++++++++ - fix issue103: introduce py.test.raises as context manager, examples:: with py.test.raises(ZeroDivisionError): x = 0 1 / x with py.test.raises(RuntimeError) as excinfo: call_something() # you may do extra checks on excinfo.value|type|traceback here (thanks Ronny Pfannschmidt) - Funcarg factories can now dynamically apply a marker to a test invocation. This is for example useful if a factory provides parameters to a test which are expected-to-fail:: def pytest_funcarg__arg(request): request.applymarker(py.test.mark.xfail(reason="flaky config")) ... def test_function(arg): ... - improved error reporting on collection and import errors. This makes use of a more general mechanism, namely that for custom test item/collect nodes ``node.repr_failure(excinfo)`` is now uniformly called so that you can override it to return a string error representation of your choice which is going to be reported as a (red) string. - introduce '--junitprefix=STR' option to prepend a prefix to all reports in the junitxml file. Bug fixes / Maintenance ++++++++++++++++++++++++++ - make tests and the ``pytest_recwarn`` plugin in particular fully compatible to Python2.7 (if you use the ``recwarn`` funcarg warnings will be enabled so that you can properly check for their existence in a cross-python manner). - refine --pdb: ignore xfailed tests, unify its TB-reporting and don't display failures again at the end. - fix assertion interpretation with the ** operator (thanks Benjamin Peterson) - fix issue105 assignment on the same line as a failing assertion (thanks Benjamin Peterson) - fix issue104 proper escaping for test names in junitxml plugin (thanks anonymous) - fix issue57 -f|--looponfail to work with xpassing tests (thanks Ronny) - fix issue92 collectonly reporter and --pastebin (thanks Benjamin Peterson) - fix py.code.compile(source) to generate unique filenames - fix assertion re-interp problems on PyPy, by defering code compilation to the (overridable) Frame.eval class. (thanks Amaury Forgeot) - fix py.path.local.pyimport() to work with directories - streamline py.path.local.mkdtemp implementation and usage - don't print empty lines when showing junitxml-filename - add optional boolean ignore_errors parameter to py.path.local.remove - fix terminal writing on win32/python2.4 - py.process.cmdexec() now tries harder to return properly encoded unicode objects on all python versions - install plain py.test/py.which scripts also for Jython, this helps to get canonical script paths in virtualenv situations - make path.bestrelpath(path) return ".", note that when calling X.bestrelpath the assumption is that X is a directory. - make initial conftest discovery ignore "--" prefixed arguments - fix resultlog plugin when used in an multicpu/multihost xdist situation (thanks Jakub Gustak) - perform distributed testing related reporting in the xdist-plugin rather than having dist-related code in the generic py.test distribution - fix homedir detection on Windows - ship distribute_setup.py version 0.6.13 v1.3.1 --------------------------------------------- New features ++++++++++++++++++ - issue91: introduce new py.test.xfail(reason) helper to imperatively mark a test as expected to fail. Can be used from within setup and test functions. This is useful especially for parametrized tests when certain configurations are expected-to-fail. In this case the declarative approach with the @py.test.mark.xfail cannot be used as it would mark all configurations as xfail. - issue102: introduce new --maxfail=NUM option to stop test runs after NUM failures. This is a generalization of the '-x' or '--exitfirst' option which is now equivalent to '--maxfail=1'. Both '-x' and '--maxfail' will now also print a line near the end indicating the Interruption. - issue89: allow py.test.mark decorators to be used on classes (class decorators were introduced with python2.6) and also allow to have multiple markers applied at class/module level by specifying a list. - improve and refine letter reporting in the progress bar: . pass f failed test s skipped tests (reminder: use for dependency/platform mismatch only) x xfailed test (test that was expected to fail) X xpassed test (test that was expected to fail but passed) You can use any combination of 'fsxX' with the '-r' extended reporting option. The xfail/xpass results will show up as skipped tests in the junitxml output - which also fixes issue99. - make py.test.cmdline.main() return the exitstatus instead of raising SystemExit and also allow it to be called multiple times. This of course requires that your application and tests are properly teared down and don't have global state. Fixes / Maintenance ++++++++++++++++++++++ - improved traceback presentation: - improved and unified reporting for "--tb=short" option - Errors during test module imports are much shorter, (using --tb=short style) - raises shows shorter more relevant tracebacks - --fulltrace now more systematically makes traces longer / inhibits cutting - improve support for raises and other dynamically compiled code by manipulating python's linecache.cache instead of the previous rather hacky way of creating custom code objects. This makes it seemlessly work on Jython and PyPy where it previously didn't. - fix issue96: make capturing more resilient against Control-C interruptions (involved somewhat substantial refactoring to the underlying capturing functionality to avoid race conditions). - fix chaining of conditional skipif/xfail decorators - so it works now as expected to use multiple @py.test.mark.skipif(condition) decorators, including specific reporting which of the conditions lead to skipping. - fix issue95: late-import zlib so that it's not required for general py.test startup. - fix issue94: make reporting more robust against bogus source code (and internally be more careful when presenting unexpected byte sequences) v1.3.0 --------------------------------------------- - deprecate --report option in favour of a new shorter and easier to remember -r option: it takes a string argument consisting of any combination of 'xfsX' characters. They relate to the single chars you see during the dotted progress printing and will print an extra line per test at the end of the test run. This extra line indicates the exact position or test ID that you directly paste to the py.test cmdline in order to re-run a particular test. - allow external plugins to register new hooks via the new pytest_addhooks(pluginmanager) hook. The new release of the pytest-xdist plugin for distributed and looponfailing testing requires this feature. - add a new pytest_ignore_collect(path, config) hook to allow projects and plugins to define exclusion behaviour for their directory structure - for example you may define in a conftest.py this method:: def pytest_ignore_collect(path): return path.check(link=1) to prevent even a collection try of any tests in symlinked dirs. - new pytest_pycollect_makemodule(path, parent) hook for allowing customization of the Module collection object for a matching test module. - extend and refine xfail mechanism: ``@py.test.mark.xfail(run=False)`` do not run the decorated test ``@py.test.mark.xfail(reason="...")`` prints the reason string in xfail summaries specifiying ``--runxfail`` on command line virtually ignores xfail markers - expose (previously internal) commonly useful methods: py.io.get_terminal_with() -> return terminal width py.io.ansi_print(...) -> print colored/bold text on linux/win32 py.io.saferepr(obj) -> return limited representation string - expose test outcome related exceptions as py.test.skip.Exception, py.test.raises.Exception etc., useful mostly for plugins doing special outcome interpretation/tweaking - (issue85) fix junitxml plugin to handle tests with non-ascii output - fix/refine python3 compatibility (thanks Benjamin Peterson) - fixes for making the jython/win32 combination work, note however: jython2.5.1/win32 does not provide a command line launcher, see http://bugs.jython.org/issue1491 . See pylib install documentation for how to work around. - fixes for handling of unicode exception values and unprintable objects - (issue87) fix unboundlocal error in assertionold code - (issue86) improve documentation for looponfailing - refine IO capturing: stdin-redirect pseudo-file now has a NOP close() method - ship distribute_setup.py version 0.6.10 - added links to the new capturelog and coverage plugins v1.2.0 --------------------------------------------- - refined usage and options for "py.cleanup":: py.cleanup # remove "*.pyc" and "*$py.class" (jython) files py.cleanup -e .swp -e .cache # also remove files with these extensions py.cleanup -s # remove "build" and "dist" directory next to setup.py files py.cleanup -d # also remove empty directories py.cleanup -a # synonym for "-s -d -e 'pip-log.txt'" py.cleanup -n # dry run, only show what would be removed - add a new option "py.test --funcargs" which shows available funcargs and their help strings (docstrings on their respective factory function) for a given test path - display a short and concise traceback if a funcarg lookup fails - early-load "conftest.py" files in non-dot first-level sub directories. allows to conveniently keep and access test-related options in a ``test`` subdir and still add command line options. - fix issue67: new super-short traceback-printing option: "--tb=line" will print a single line for each failing (python) test indicating its filename, lineno and the failure value - fix issue78: always call python-level teardown functions even if the according setup failed. This includes refinements for calling setup_module/class functions which will now only be called once instead of the previous behaviour where they'd be called multiple times if they raise an exception (including a Skipped exception). Any exception will be re-corded and associated with all tests in the according module/class scope. - fix issue63: assume <40 columns to be a bogus terminal width, default to 80 - fix pdb debugging to be in the correct frame on raises-related errors - update apipkg.py to fix an issue where recursive imports might unnecessarily break importing - fix plugin links v1.1.1 --------------------------------------------- - moved dist/looponfailing from py.test core into a new separately released pytest-xdist plugin. - new junitxml plugin: --junitxml=path will generate a junit style xml file which is processable e.g. by the Hudson CI system. - new option: --genscript=path will generate a standalone py.test script which will not need any libraries installed. thanks to Ralf Schmitt. - new option: --ignore will prevent specified path from collection. Can be specified multiple times. - new option: --confcutdir=dir will make py.test only consider conftest files that are relative to the specified dir. - new funcarg: "pytestconfig" is the pytest config object for access to command line args and can now be easily used in a test. - install 'py.test' and `py.which` with a ``-$VERSION`` suffix to disambiguate between Python3, python2.X, Jython and PyPy installed versions. - new "pytestconfig" funcarg allows access to test config object - new "pytest_report_header" hook can return additional lines to be displayed at the header of a test run. - (experimental) allow "py.test path::name1::name2::..." for pointing to a test within a test collection directly. This might eventually evolve as a full substitute to "-k" specifications. - streamlined plugin loading: order is now as documented in customize.html: setuptools, ENV, commandline, conftest. also setuptools entry point names are turned to canonical namees ("pytest_*") - automatically skip tests that need 'capfd' but have no os.dup - allow pytest_generate_tests to be defined in classes as well - deprecate usage of 'disabled' attribute in favour of pytestmark - deprecate definition of Directory, Module, Class and Function nodes in conftest.py files. Use pytest collect hooks instead. - collection/item node specific runtest/collect hooks are only called exactly on matching conftest.py files, i.e. ones which are exactly below the filesystem path of an item - change: the first pytest_collect_directory hook to return something will now prevent further hooks to be called. - change: figleaf plugin now requires --figleaf to run. Also change its long command line options to be a bit shorter (see py.test -h). - change: pytest doctest plugin is now enabled by default and has a new option --doctest-glob to set a pattern for file matches. - change: remove internal py._* helper vars, only keep py._pydir - robustify capturing to survive if custom pytest_runtest_setup code failed and prevented the capturing setup code from running. - make py.test.* helpers provided by default plugins visible early - works transparently both for pydoc and for interactive sessions which will regularly see e.g. py.test.mark and py.test.importorskip. - simplify internal plugin manager machinery - simplify internal collection tree by introducing a RootCollector node - fix assert reinterpreation that sees a call containing "keyword=..." - fix issue66: invoke pytest_sessionstart and pytest_sessionfinish hooks on slaves during dist-testing, report module/session teardown hooks correctly. - fix issue65: properly handle dist-testing if no execnet/py lib installed remotely. - skip some install-tests if no execnet is available - fix docs, fix internal bin/ script generation v1.1.0 --------------------------------------------- - introduce automatic plugin registration via 'pytest11' entrypoints via setuptools' pkg_resources.iter_entry_points - fix py.test dist-testing to work with execnet >= 1.0.0b4 - re-introduce py.test.cmdline.main() for better backward compatibility - svn paths: fix a bug with path.check(versioned=True) for svn paths, allow '%' in svn paths, make svnwc.update() default to interactive mode like in 1.0.x and add svnwc.update(interactive=False) to inhibit interaction. - refine distributed tarball to contain test and no pyc files - try harder to have deprecation warnings for py.compat.* accesses report a correct location v1.0.2 --------------------------------------------- * adjust and improve docs * remove py.rest tool and internal namespace - it was never really advertised and can still be used with the old release if needed. If there is interest it could be revived into its own tool i guess. * fix issue48 and issue59: raise an Error if the module from an imported test file does not seem to come from the filepath - avoids "same-name" confusion that has been reported repeatedly * merged Ronny's nose-compatibility hacks: now nose-style setup_module() and setup() functions are supported * introduce generalized py.test.mark function marking * reshuffle / refine command line grouping * deprecate parser.addgroup in favour of getgroup which creates option group * add --report command line option that allows to control showing of skipped/xfailed sections * generalized skipping: a new way to mark python functions with skipif or xfail at function, class and modules level based on platform or sys-module attributes. * extend py.test.mark decorator to allow for positional args * introduce and test "py.cleanup -d" to remove empty directories * fix issue #59 - robustify unittest test collection * make bpython/help interaction work by adding an __all__ attribute to ApiModule, cleanup initpkg * use MIT license for pylib, add some contributors * remove py.execnet code and substitute all usages with 'execnet' proper * fix issue50 - cached_setup now caches more to expectations for test functions with multiple arguments. * merge Jarko's fixes, issue #45 and #46 * add the ability to specify a path for py.lookup to search in * fix a funcarg cached_setup bug probably only occuring in distributed testing and "module" scope with teardown. * many fixes and changes for making the code base python3 compatible, many thanks to Benjamin Peterson for helping with this. * consolidate builtins implementation to be compatible with >=2.3, add helpers to ease keeping 2 and 3k compatible code * deprecate py.compat.doctest|subprocess|textwrap|optparse * deprecate py.magic.autopath, remove py/magic directory * move pytest assertion handling to py/code and a pytest_assertion plugin, add "--no-assert" option, deprecate py.magic namespaces in favour of (less) py.code ones. * consolidate and cleanup py/code classes and files * cleanup py/misc, move tests to bin-for-dist * introduce delattr/delitem/delenv methods to py.test's monkeypatch funcarg * consolidate py.log implementation, remove old approach. * introduce py.io.TextIO and py.io.BytesIO for distinguishing between text/unicode and byte-streams (uses underlying standard lib io.* if available) * make py.unittest_convert helper script available which converts "unittest.py" style files into the simpler assert/direct-test-classes py.test/nosetests style. The script was written by Laura Creighton. * simplified internal localpath implementation v1.0.2 ------------------------------------------- * fixing packaging issues, triggered by fedora redhat packaging, also added doc, examples and contrib dirs to the tarball. * added a documentation link to the new django plugin. v1.0.1 ------------------------------------------- * added a 'pytest_nose' plugin which handles nose.SkipTest, nose-style function/method/generator setup/teardown and tries to report functions correctly. * capturing of unicode writes or encoded strings to sys.stdout/err work better, also terminalwriting was adapted and somewhat unified between windows and linux. * improved documentation layout and content a lot * added a "--help-config" option to show conftest.py / ENV-var names for all longopt cmdline options, and some special conftest.py variables. renamed 'conf_capture' conftest setting to 'option_capture' accordingly. * fix issue #27: better reporting on non-collectable items given on commandline (e.g. pyc files) * fix issue #33: added --version flag (thanks Benjamin Peterson) * fix issue #32: adding support for "incomplete" paths to wcpath.status() * "Test" prefixed classes are *not* collected by default anymore if they have an __init__ method * monkeypatch setenv() now accepts a "prepend" parameter * improved reporting of collection error tracebacks * simplified multicall mechanism and plugin architecture, renamed some internal methods and argnames v1.0.0 ------------------------------------------- * more terse reporting try to show filesystem path relatively to current dir * improve xfail output a bit v1.0.0b9 ------------------------------------------- * cleanly handle and report final teardown of test setup * fix svn-1.6 compat issue with py.path.svnwc().versioned() (thanks Wouter Vanden Hove) * setup/teardown or collection problems now show as ERRORs or with big "E"'s in the progress lines. they are reported and counted separately. * dist-testing: properly handle test items that get locally collected but cannot be collected on the remote side - often due to platform/dependency reasons * simplified py.test.mark API - see keyword plugin documentation * integrate better with logging: capturing now by default captures test functions and their immediate setup/teardown in a single stream * capsys and capfd funcargs now have a readouterr() and a close() method (underlyingly py.io.StdCapture/FD objects are used which grew a readouterr() method as well to return snapshots of captured out/err) * make assert-reinterpretation work better with comparisons not returning bools (reported with numpy from thanks maciej fijalkowski) * reworked per-test output capturing into the pytest_iocapture.py plugin and thus removed capturing code from config object * item.repr_failure(excinfo) instead of item.repr_failure(excinfo, outerr) v1.0.0b8 ------------------------------------------- * pytest_unittest-plugin is now enabled by default * introduced pytest_keyboardinterrupt hook and refined pytest_sessionfinish hooked, added tests. * workaround a buggy logging module interaction ("closing already closed files"). Thanks to Sridhar Ratnakumar for triggering. * if plugins use "py.test.importorskip" for importing a dependency only a warning will be issued instead of exiting the testing process. * many improvements to docs: - refined funcargs doc , use the term "factory" instead of "provider" - added a new talk/tutorial doc page - better download page - better plugin docstrings - added new plugins page and automatic doc generation script * fixed teardown problem related to partially failing funcarg setups (thanks MrTopf for reporting), "pytest_runtest_teardown" is now always invoked even if the "pytest_runtest_setup" failed. * tweaked doctest output for docstrings in py modules, thanks Radomir. v1.0.0b7 ------------------------------------------- * renamed py.test.xfail back to py.test.mark.xfail to avoid two ways to decorate for xfail * re-added py.test.mark decorator for setting keywords on functions (it was actually documented so removing it was not nice) * remove scope-argument from request.addfinalizer() because request.cached_setup has the scope arg. TOOWTDI. * perform setup finalization before reporting failures * apply modified patches from Andreas Kloeckner to allow test functions to have no func_code (#22) and to make "-k" and function keywords work (#20) * apply patch from Daniel Peolzleithner (issue #23) * resolve issue #18, multiprocessing.Manager() and redirection clash * make __name__ == "__channelexec__" for remote_exec code v1.0.0b3 ------------------------------------------- * plugin classes are removed: one now defines hooks directly in conftest.py or global pytest_*.py files. * added new pytest_namespace(config) hook that allows to inject helpers directly to the py.test.* namespace. * documented and refined many hooks * added new style of generative tests via pytest_generate_tests hook that integrates well with function arguments. v1.0.0b1 ------------------------------------------- * introduced new "funcarg" setup method, see doc/test/funcarg.txt * introduced plugin architecture and many new py.test plugins, see doc/test/plugins.txt * teardown_method is now guaranteed to get called after a test method has run. * new method: py.test.importorskip(mod,minversion) will either import or call py.test.skip() * completely revised internal py.test architecture * new py.process.ForkedFunc object allowing to fork execution of a function to a sub process and getting a result back. XXX lots of things missing here XXX v0.9.2 ------------------------------------------- * refined installation and metadata, created new setup.py, now based on setuptools/ez_setup (thanks to Ralf Schmitt for his support). * improved the way of making py.* scripts available in windows environments, they are now added to the Scripts directory as ".cmd" files. * py.path.svnwc.status() now is more complete and uses xml output from the 'svn' command if available (Guido Wesdorp) * fix for py.path.svn* to work with svn 1.5 (Chris Lamb) * fix path.relto(otherpath) method on windows to use normcase for checking if a path is relative. * py.test's traceback is better parseable from editors (follows the filenames:LINENO: MSG convention) (thanks to Osmo Salomaa) * fix to javascript-generation, "py.test --runbrowser" should work more reliably now * removed previously accidentally added py.test.broken and py.test.notimplemented helpers. * there now is a py.__version__ attribute v0.9.1 ------------------------------------------- This is a fairly complete list of v0.9.1, which can serve as a reference for developers. * allowing + signs in py.path.svn urls [39106] * fixed support for Failed exceptions without excinfo in py.test [39340] * added support for killing processes for Windows (as well as platforms that support os.kill) in py.misc.killproc [39655] * added setup/teardown for generative tests to py.test [40702] * added detection of FAILED TO LOAD MODULE to py.test [40703, 40738, 40739] * fixed problem with calling .remove() on wcpaths of non-versioned files in py.path [44248] * fixed some import and inheritance issues in py.test [41480, 44648, 44655] * fail to run greenlet tests when pypy is available, but without stackless [45294] * small fixes in rsession tests [45295] * fixed issue with 2.5 type representations in py.test [45483, 45484] * made that internal reporting issues displaying is done atomically in py.test [45518] * made that non-existing files are igored by the py.lookup script [45519] * improved exception name creation in py.test [45535] * made that less threads are used in execnet [merge in 45539] * removed lock required for atomical reporting issue displaying in py.test [45545] * removed globals from execnet [45541, 45547] * refactored cleanup mechanics, made that setDaemon is set to 1 to make atexit get called in 2.5 (py.execnet) [45548] * fixed bug in joining threads in py.execnet's servemain [45549] * refactored py.test.rsession tests to not rely on exact output format anymore [45646] * using repr() on test outcome [45647] * added 'Reason' classes for py.test.skip() [45648, 45649] * killed some unnecessary sanity check in py.test.collect [45655] * avoid using os.tmpfile() in py.io.fdcapture because on Windows it's only usable by Administrators [45901] * added support for locking and non-recursive commits to py.path.svnwc [45994] * locking files in py.execnet to prevent CPython from segfaulting [46010] * added export() method to py.path.svnurl * fixed -d -x in py.test [47277] * fixed argument concatenation problem in py.path.svnwc [49423] * restore py.test behaviour that it exits with code 1 when there are failures [49974] * don't fail on html files that don't have an accompanying .txt file [50606] * fixed 'utestconvert.py < input' [50645] * small fix for code indentation in py.code.source [50755] * fix _docgen.py documentation building [51285] * improved checks for source representation of code blocks in py.test [51292] * added support for passing authentication to py.path.svn* objects [52000, 52001] * removed sorted() call for py.apigen tests in favour of [].sort() to support Python 2.3 [52481] pytest-2.8.7/AUTHORS0000664000175000017500000000227012651247335014477 0ustar ronnyronny00000000000000Holger Krekel, holger at merlinux eu merlinux GmbH, Germany, office at merlinux eu Contributors include:: Abhijeet Kasurde Anatoly Bubenkoff Andreas Zeidler Andy Freeland Anthon van der Neut Armin Rigo Aron Curzon Benjamin Peterson Bob Ippolito Brian Dorsey Brian Okken Brianna Laugher Bruno Oliveira Carl Friedrich Bolz Charles Cloud Chris Lamb Christian Theunert Christian Tismer Christopher Gilling Daniel Grana Daniel Nuri Dave Hunt David Mohr Edison Gustavo Muenz Eduardo Schettino Elizaveta Shashkova Eric Hunsberger Eric Siegerman Erik M.

Let's look at a simple standalone-example using the ``yield`` syntax:: # content of test_yield.py import pytest @pytest.yield_fixture def passwd(): print ("\nsetup before yield") f = open("/etc/passwd") yield f.readlines() print ("teardown after yield") f.close() def test_has_lines(passwd): print ("test called") assert passwd In contrast to :ref:`finalization through registering callbacks `, our fixture function used a ``yield`` statement to provide the lines of the ``/etc/passwd`` file. The code after the ``yield`` statement serves as the teardown code, avoiding the indirection of registering a teardown callback function. Let's run it with output capturing disabled:: $ py.test -q -s test_yield.py setup before yield test called .teardown after yield 1 passed in 0.12 seconds We can also seamlessly use the new syntax with ``with`` statements. Let's simplify the above ``passwd`` fixture:: # content of test_yield2.py import pytest @pytest.yield_fixture def passwd(): with open("/etc/passwd") as f: yield f.readlines() def test_has_lines(passwd): assert len(passwd) >= 1 The file ``f`` will be closed after the test finished execution because the Python ``file`` object supports finalization when the ``with`` statement ends. Note that the yield fixture form supports all other fixture features such as ``scope``, ``params``, etc., thus changing existing fixture functions to use ``yield`` is straightforward. .. note:: While the ``yield`` syntax is similar to what :py:func:`contextlib.contextmanager` decorated functions provide, with pytest fixture functions the part after the "yield" will always be invoked, independently from the exception status of the test function which uses the fixture. This behaviour makes sense if you consider that many different test functions might use a module or session scoped fixture. Discussion and future considerations / feedback ++++++++++++++++++++++++++++++++++++++++++++++++++++ There are some topics that are worth mentioning: - usually ``yield`` is used for producing multiple values. But fixture functions can only yield exactly one value. Yielding a second fixture value will get you an error. It's possible we can evolve pytest to allow for producing multiple values as an alternative to current parametrization. For now, you can just use the normal :ref:`fixture parametrization ` mechanisms together with ``yield``-style fixtures. - lastly ``yield`` introduces more than one way to write fixture functions, so what's the obvious way to a newcomer? If you want to feedback or participate in discussion of the above topics, please join our :ref:`contact channels`, you are most welcome. pytest-2.8.7/doc/en/xunit_setup.rst0000664000175000017500000000617412651247335017726 0ustar ronnyronny00000000000000 .. _`classic xunit`: .. _xunitsetup: classic xunit-style setup ======================================== This section describes a classic and popular way how you can implement fixtures (setup and teardown test state) on a per-module/class/function basis. pytest started supporting these methods around 2005 and subsequently nose and the standard library introduced them (under slightly different names). While these setup/teardown methods are and will remain fully supported you may also use pytest's more powerful :ref:`fixture mechanism ` which leverages the concept of dependency injection, allowing for a more modular and more scalable approach for managing test state, especially for larger projects and for functional testing. You can mix both fixture mechanisms in the same file but unittest-based test methods cannot receive fixture arguments. .. note:: As of pytest-2.4, teardownX functions are not called if setupX existed and failed/was skipped. This harmonizes behaviour across all major python testing tools. Module level setup/teardown -------------------------------------- If you have multiple test functions and test classes in a single module you can optionally implement the following fixture methods which will usually be called once for all the functions:: def setup_module(module): """ setup any state specific to the execution of the given module.""" def teardown_module(module): """ teardown any state that was previously setup with a setup_module method. """ Class level setup/teardown ---------------------------------- Similarly, the following methods are called at class level before and after all test methods of the class are called:: @classmethod def setup_class(cls): """ setup any state specific to the execution of the given class (which usually contains tests). """ @classmethod def teardown_class(cls): """ teardown any state that was previously setup with a call to setup_class. """ Method and function level setup/teardown ----------------------------------------------- Similarly, the following methods are called around each method invocation:: def setup_method(self, method): """ setup any state tied to the execution of the given method in a class. setup_method is invoked for every test method of a class. """ def teardown_method(self, method): """ teardown any state that was previously setup with a setup_method call. """ If you would rather define test functions directly at module level you can also use the following functions to implement fixtures:: def setup_function(function): """ setup any state tied to the execution of the given function. Invoked for every test function in the module. """ def teardown_function(function): """ teardown any state that was previously setup with a setup_function call. """ Note that it is possible for setup/teardown pairs to be invoked multiple times per testing process. .. _`unittest.py module`: http://docs.python.org/library/unittest.html pytest-2.8.7/doc/en/xdist.rst0000664000175000017500000001431612651247335016467 0ustar ronnyronny00000000000000 .. _`xdist`: xdist: pytest distributed testing plugin =============================================================== The `pytest-xdist`_ plugin extends ``pytest`` with some unique test execution modes: * Looponfail: run your tests repeatedly in a subprocess. After each run, ``pytest`` waits until a file in your project changes and then re-runs the previously failing tests. This is repeated until all tests pass. At this point a full run is again performed. * multiprocess Load-balancing: if you have multiple CPUs or hosts you can use them for a combined test run. This allows to speed up development or to use special resources of remote machines. * Multi-Platform coverage: you can specify different Python interpreters or different platforms and run tests in parallel on all of them. Before running tests remotely, ``pytest`` efficiently "rsyncs" your program source code to the remote place. All test results are reported back and displayed to your local terminal. You may specify different Python versions and interpreters. Installation of xdist plugin ------------------------------ Install the plugin with:: easy_install pytest-xdist # or pip install pytest-xdist or use the package in develop/in-place mode with a checkout of the `pytest-xdist repository`_ :: python setup.py develop Usage examples --------------------- .. _`xdistcpu`: Speed up test runs by sending tests to multiple CPUs +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ To send tests to multiple CPUs, type:: py.test -n NUM Especially for longer running tests or tests requiring a lot of I/O this can lead to considerable speed ups. Running tests in a Python subprocess +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ To instantiate a Python-2.4 subprocess and send tests to it, you may type:: py.test -d --tx popen//python=python2.4 This will start a subprocess which is run with the "python2.4" Python interpreter, found in your system binary lookup path. If you prefix the --tx option value like this:: py.test -d --tx 3*popen//python=python2.4 then three subprocesses would be created and the tests will be distributed to three subprocesses and run simultanously. .. _looponfailing: Running tests in looponfailing mode +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ For refactoring a project with a medium or large test suite you can use the looponfailing mode. Simply add the ``--f`` option:: py.test -f and ``pytest`` will run your tests. Assuming you have failures it will then wait for file changes and re-run the failing test set. File changes are detected by looking at ``looponfailingroots`` root directories and all of their contents (recursively). If the default for this value does not work for you you can change it in your project by setting a configuration option:: # content of a pytest.ini, setup.cfg or tox.ini file [pytest] looponfailroots = mypkg testdir This would lead to only looking for file changes in the respective directories, specified relatively to the ini-file's directory. Sending tests to remote SSH accounts +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Suppose you have a package ``mypkg`` which contains some tests that you can successfully run locally. And you also have a ssh-reachable machine ``myhost``. Then you can ad-hoc distribute your tests by typing:: py.test -d --tx ssh=myhostpopen --rsyncdir mypkg mypkg This will synchronize your ``mypkg`` package directory with a remote ssh account and then collect and run your tests at the remote side. You can specify multiple ``--rsyncdir`` directories to be sent to the remote side. .. XXX CHECK **NOTE:** For ``pytest`` to collect and send tests correctly you not only need to make sure all code and tests directories are rsynced, but that any test (sub) directory also has an ``__init__.py`` file because internally ``pytest`` references tests as a fully qualified python module path. **You will otherwise get strange errors** during setup of the remote side. Sending tests to remote Socket Servers +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Download the single-module `socketserver.py`_ Python program and run it like this:: python socketserver.py It will tell you that it starts listening on the default port. You can now on your home machine specify this new socket host with something like this:: py.test -d --tx socket=192.168.1.102:8888 --rsyncdir mypkg mypkg .. _`atonce`: Running tests on many platforms at once +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The basic command to run tests on multiple platforms is:: py.test --dist=each --tx=spec1 --tx=spec2 If you specify a windows host, an OSX host and a Linux environment this command will send each tests to all platforms - and report back failures from all platforms at once. The specifications strings use the `xspec syntax`_. .. _`xspec syntax`: http://codespeak.net/execnet/basics.html#xspec .. _`socketserver.py`: http://bitbucket.org/hpk42/execnet/raw/2af991418160/execnet/script/socketserver.py .. _`execnet`: http://codespeak.net/execnet Specifying test exec environments in an ini file +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ pytest (since version 2.0) supports ini-style configuration. For example, you could make running with three subprocesses your default:: [pytest] addopts = -n3 You can also add default environments like this:: [pytest] addopts = --tx ssh=myhost//python=python2.5 --tx ssh=myhost//python=python2.6 and then just type:: py.test --dist=each to run tests in each of the environments. Specifying "rsync" dirs in an ini-file +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ In a ``tox.ini`` or ``setup.cfg`` file in your root project directory you may specify directories to include or to exclude in synchronisation:: [pytest] rsyncdirs = . mypkg helperpkg rsyncignore = .hg These directory specifications are relative to the directory where the configuration file was found. .. _`pytest-xdist`: http://pypi.python.org/pypi/pytest-xdist .. _`pytest-xdist repository`: http://bitbucket.org/pytest-dev/pytest-xdist .. _`pytest`: http://pytest.org pytest-2.8.7/doc/en/writing_plugins.rst0000664000175000017500000004435212651247335020563 0ustar ronnyronny00000000000000.. _plugins: .. _`writing-plugins`: Writing plugins =============== It is easy to implement `local conftest plugins`_ for your own project or `pip-installable plugins`_ that can be used throughout many projects, including third party projects. Please refer to :ref:`using plugins` if you only want to use but not write plugins. A plugin contains one or multiple hook functions. :ref:`Writing hooks ` explains the basics and details of how you can write a hook function yourself. ``pytest`` implements all aspects of configuration, collection, running and reporting by calling `well specified hooks`_ of the following plugins: * :ref:`builtin plugins`: loaded from pytest's internal ``_pytest`` directory. * :ref:`external plugins `: modules discovered through `setuptools entry points`_ * `conftest.py plugins`_: modules auto-discovered in test directories In principle, each hook call is a ``1:N`` Python function call where ``N`` is the number of registered implementation functions for a given specification. All specifications and implementations following the ``pytest_`` prefix naming convention, making them easy to distinguish and find. .. _`pluginorder`: Plugin discovery order at tool startup -------------------------------------- ``pytest`` loads plugin modules at tool startup in the following way: * by loading all builtin plugins * by loading all plugins registered through `setuptools entry points`_. * by pre-scanning the command line for the ``-p name`` option and loading the specified plugin before actual command line parsing. * by loading all :file:`conftest.py` files as inferred by the command line invocation: - if no test paths are specified use current dir as a test path - if exists, load ``conftest.py`` and ``test*/conftest.py`` relative to the directory part of the first test path. Note that pytest does not find ``conftest.py`` files in deeper nested sub directories at tool startup. It is usually a good idea to keep your conftest.py file in the top level test or project root directory. * by recursively loading all plugins specified by the ``pytest_plugins`` variable in ``conftest.py`` files .. _`pytest/plugin`: http://bitbucket.org/pytest-dev/pytest/src/tip/pytest/plugin/ .. _`conftest.py plugins`: .. _`conftest.py`: .. _`localplugin`: .. _`conftest`: .. _`local conftest plugins`: conftest.py: local per-directory plugins ---------------------------------------- Local ``conftest.py`` plugins contain directory-specific hook implementations. Hook Session and test running activities will invoke all hooks defined in ``conftest.py`` files closer to the root of the filesystem. Example of implementing the ``pytest_runtest_setup`` hook so that is called for tests in the ``a`` sub directory but not for other directories:: a/conftest.py: def pytest_runtest_setup(item): # called for running each test in 'a' directory print ("setting up", item) a/test_sub.py: def test_sub(): pass test_flat.py: def test_flat(): pass Here is how you might run it:: py.test test_flat.py # will not show "setting up" py.test a/test_sub.py # will show "setting up" .. Note:: If you have ``conftest.py`` files which do not reside in a python package directory (i.e. one containing an ``__init__.py``) then "import conftest" can be ambiguous because there might be other ``conftest.py`` files as well on your PYTHONPATH or ``sys.path``. It is thus good practice for projects to either put ``conftest.py`` under a package scope or to never import anything from a conftest.py file. Writing your own plugin ----------------------- .. _`setuptools`: http://pypi.python.org/pypi/setuptools If you want to write a plugin, there are many real-life examples you can copy from: * a custom collection example plugin: :ref:`yaml plugin` * around 20 doc:`builtin plugins` which provide pytest's own functionality * many `external plugins `_ providing additional features All of these plugins implement the documented `well specified hooks`_ to extend and add functionality. .. note:: Make sure to check out the excellent `cookiecutter-pytest-plugin `_ project, which is a `cookiecutter template `_ for authoring plugins. The template provides an excellent starting point with a working plugin, tests running with tox, comprehensive README and entry-pointy already pre-configured. Also consider :ref:`contributing your plugin to pytest-dev` once it has some happy users other than yourself. .. _`setuptools entry points`: .. _`pip-installable plugins`: Making your plugin installable by others ---------------------------------------- If you want to make your plugin externally available, you may define a so-called entry point for your distribution so that ``pytest`` finds your plugin module. Entry points are a feature that is provided by `setuptools`_. pytest looks up the ``pytest11`` entrypoint to discover its plugins and you can thus make your plugin available by defining it in your setuptools-invocation: .. sourcecode:: python # sample ./setup.py file from setuptools import setup setup( name="myproject", packages = ['myproject'] # the following makes a plugin available to pytest entry_points = { 'pytest11': [ 'name_of_plugin = myproject.pluginmodule', ] }, ) If a package is installed this way, ``pytest`` will load ``myproject.pluginmodule`` as a plugin which can define `well specified hooks`_. Requiring/Loading plugins in a test module or conftest file ----------------------------------------------------------- You can require plugins in a test module or a conftest file like this:: pytest_plugins = "name1", "name2", When the test module or conftest plugin is loaded the specified plugins will be loaded as well. You can also use dotted path like this:: pytest_plugins = "myapp.testsupport.myplugin" which will import the specified module as a ``pytest`` plugin. Accessing another plugin by name -------------------------------- If a plugin wants to collaborate with code from another plugin it can obtain a reference through the plugin manager like this: .. sourcecode:: python plugin = config.pluginmanager.getplugin("name_of_plugin") If you want to look at the names of existing plugins, use the ``--traceconfig`` option. Testing plugins --------------- pytest comes with some facilities that you can enable for testing your plugin. Given that you have an installed plugin you can enable the :py:class:`testdir <_pytest.pytester.Testdir>` fixture via specifying a command line option to include the pytester plugin (``-p pytester``) or by putting ``pytest_plugins = "pytester"`` into your test or ``conftest.py`` file. You then will have a ``testdir`` fixture which you can use like this:: # content of test_myplugin.py pytest_plugins = "pytester" # to get testdir fixture def test_myplugin(testdir): testdir.makepyfile(""" def test_example(): pass """) result = testdir.runpytest("--verbose") result.fnmatch_lines(""" test_example* """) Note that by default ``testdir.runpytest()`` will perform a pytest in-process. You can pass the command line option ``--runpytest=subprocess`` to have it happen in a subprocess. Also see the :py:class:`RunResult <_pytest.pytester.RunResult>` for more methods of the result object that you get from a call to ``runpytest``. .. _`writinghooks`: Writing hook functions ====================== .. _validation: hook function validation and execution -------------------------------------- pytest calls hook functions from registered plugins for any given hook specification. Let's look at a typical hook function for the ``pytest_collection_modifyitems(session, config, items)`` hook which pytest calls after collection of all test items is completed. When we implement a ``pytest_collection_modifyitems`` function in our plugin pytest will during registration verify that you use argument names which match the specification and bail out if not. Let's look at a possible implementation: .. code-block:: python def pytest_collection_modifyitems(config, items): # called after collection is completed # you can modify the ``items`` list Here, ``pytest`` will pass in ``config`` (the pytest config object) and ``items`` (the list of collected test items) but will not pass in the ``session`` argument because we didn't list it in the function signature. This dynamic "pruning" of arguments allows ``pytest`` to be "future-compatible": we can introduce new hook named parameters without breaking the signatures of existing hook implementations. It is one of the reasons for the general long-lived compatibility of pytest plugins. Note that hook functions other than ``pytest_runtest_*`` are not allowed to raise exceptions. Doing so will break the pytest run. firstresult: stop at first non-None result ------------------------------------------- Most calls to ``pytest`` hooks result in a **list of results** which contains all non-None results of the called hook functions. Some hook specifications use the ``firstresult=True`` option so that the hook call only executes until the first of N registered functions returns a non-None result which is then taken as result of the overall hook call. The remaining hook functions will not be called in this case. hookwrapper: executing around other hooks ------------------------------------------------- .. currentmodule:: _pytest.core .. versionadded:: 2.7 (experimental) pytest plugins can implement hook wrappers which wrap the execution of other hook implementations. A hook wrapper is a generator function which yields exactly once. When pytest invokes hooks it first executes hook wrappers and passes the same arguments as to the regular hooks. At the yield point of the hook wrapper pytest will execute the next hook implementations and return their result to the yield point in the form of a :py:class:`CallOutcome` instance which encapsulates a result or exception info. The yield point itself will thus typically not raise exceptions (unless there are bugs). Here is an example definition of a hook wrapper:: import pytest @pytest.hookimpl(hookwrapper=True) def pytest_pyfunc_call(pyfuncitem): # do whatever you want before the next hook executes outcome = yield # outcome.excinfo may be None or a (cls, val, tb) tuple res = outcome.get_result() # will raise if outcome was exception # postprocess result Note that hook wrappers don't return results themselves, they merely perform tracing or other side effects around the actual hook implementations. If the result of the underlying hook is a mutable object, they may modify that result but it's probably better to avoid it. Hook function ordering / call example ------------------------------------- For any given hook specification there may be more than one implementation and we thus generally view ``hook`` execution as a ``1:N`` function call where ``N`` is the number of registered functions. There are ways to influence if a hook implementation comes before or after others, i.e. the position in the ``N``-sized list of functions: .. code-block:: python # Plugin 1 @pytest.hookimpl(tryfirst=True) def pytest_collection_modifyitems(items): # will execute as early as possible # Plugin 2 @pytest.hookimpl(trylast=True) def pytest_collection_modifyitems(items): # will execute as late as possible # Plugin 3 @pytest.hookimpl(hookwrapper=True) def pytest_collection_modifyitems(items): # will execute even before the tryfirst one above! outcome = yield # will execute after all non-hookwrappers executed Here is the order of execution: 1. Plugin3's pytest_collection_modifyitems called until the yield point because it is a hook wrapper. 2. Plugin1's pytest_collection_modifyitems is called because it is marked with ``tryfirst=True``. 3. Plugin2's pytest_collection_modifyitems is called because it is marked with ``trylast=True`` (but even without this mark it would come after Plugin1). 4. Plugin3's pytest_collection_modifyitems then executing the code after the yield point. The yield receives a :py:class:`CallOutcome` instance which encapsulates the result from calling the non-wrappers. Wrappers shall not modify the result. It's possible to use ``tryfirst`` and ``trylast`` also in conjunction with ``hookwrapper=True`` in which case it will influence the ordering of hookwrappers among each other. Declaring new hooks ------------------------ .. currentmodule:: _pytest.hookspec Plugins and ``conftest.py`` files may declare new hooks that can then be implemented by other plugins in order to alter behaviour or interact with the new plugin: .. autofunction:: pytest_addhooks Hooks are usually declared as do-nothing functions that contain only documentation describing when the hook will be called and what return values are expected. For an example, see `newhooks.py`_ from :ref:`xdist`. .. _`newhooks.py`: https://github.com/pytest-dev/pytest-xdist/blob/974bd566c599dc6a9ea291838c6f226197208b46/xdist/newhooks.py Optionally using hooks from 3rd party plugins --------------------------------------------- Using new hooks from plugins as explained above might be a little tricky because of the standard :ref:`validation mechanism `: if you depend on a plugin that is not installed, validation will fail and the error message will not make much sense to your users. One approach is to defer the hook implementation to a new plugin instead of declaring the hook functions directly in your plugin module, for example:: # contents of myplugin.py class DeferPlugin(object): """Simple plugin to defer pytest-xdist hook functions.""" def pytest_testnodedown(self, node, error): """standard xdist hook function. """ def pytest_configure(config): if config.pluginmanager.hasplugin('xdist'): config.pluginmanager.register(DeferPlugin()) This has the added benefit of allowing you to conditionally install hooks depending on which plugins are installed. .. _`well specified hooks`: .. currentmodule:: _pytest.hookspec pytest hook reference ===================== Initialization, command line and configuration hooks ---------------------------------------------------- .. autofunction:: pytest_load_initial_conftests .. autofunction:: pytest_cmdline_preparse .. autofunction:: pytest_cmdline_parse .. autofunction:: pytest_namespace .. autofunction:: pytest_addoption .. autofunction:: pytest_cmdline_main .. autofunction:: pytest_configure .. autofunction:: pytest_unconfigure Generic "runtest" hooks ----------------------- All runtest related hooks receive a :py:class:`pytest.Item` object. .. autofunction:: pytest_runtest_protocol .. autofunction:: pytest_runtest_setup .. autofunction:: pytest_runtest_call .. autofunction:: pytest_runtest_teardown .. autofunction:: pytest_runtest_makereport For deeper understanding you may look at the default implementation of these hooks in :py:mod:`_pytest.runner` and maybe also in :py:mod:`_pytest.pdb` which interacts with :py:mod:`_pytest.capture` and its input/output capturing in order to immediately drop into interactive debugging when a test failure occurs. The :py:mod:`_pytest.terminal` reported specifically uses the reporting hook to print information about a test run. Collection hooks ---------------- ``pytest`` calls the following hooks for collecting files and directories: .. autofunction:: pytest_ignore_collect .. autofunction:: pytest_collect_directory .. autofunction:: pytest_collect_file For influencing the collection of objects in Python modules you can use the following hook: .. autofunction:: pytest_pycollect_makeitem .. autofunction:: pytest_generate_tests After collection is complete, you can modify the order of items, delete or otherwise amend the test items: .. autofunction:: pytest_collection_modifyitems Reporting hooks --------------- Session related reporting hooks: .. autofunction:: pytest_collectstart .. autofunction:: pytest_itemcollected .. autofunction:: pytest_collectreport .. autofunction:: pytest_deselected .. autofunction:: pytest_report_header .. autofunction:: pytest_report_teststatus .. autofunction:: pytest_terminal_summary And here is the central hook for reporting about test execution: .. autofunction:: pytest_runtest_logreport You can also use this hook to customize assertion representation for some types: .. autofunction:: pytest_assertrepr_compare Debugging/Interaction hooks --------------------------- There are few hooks which can be used for special reporting or interaction with exceptions: .. autofunction:: pytest_internalerror .. autofunction:: pytest_keyboard_interrupt .. autofunction:: pytest_exception_interact .. autofunction:: pytest_enter_pdb Reference of objects involved in hooks ====================================== .. autoclass:: _pytest.config.Config() :members: .. autoclass:: _pytest.config.Parser() :members: .. autoclass:: _pytest.main.Node() :members: .. autoclass:: _pytest.main.Collector() :members: :show-inheritance: .. autoclass:: _pytest.main.Item() :members: :show-inheritance: .. autoclass:: _pytest.python.Module() :members: :show-inheritance: .. autoclass:: _pytest.python.Class() :members: :show-inheritance: .. autoclass:: _pytest.python.Function() :members: :show-inheritance: .. autoclass:: _pytest.runner.CallInfo() :members: .. autoclass:: _pytest.runner.TestReport() :members: .. autoclass:: _pytest.core.CallOutcome() :members: .. autofunction:: _pytest.config.get_plugin_manager() .. autoclass:: _pytest.config.PytestPluginManager() :members: :undoc-members: :show-inheritance: .. autoclass:: pluggy.PluginManager() :members: .. currentmodule:: _pytest.pytester .. autoclass:: Testdir() :members: runpytest,runpytest_subprocess,runpytest_inprocess,makeconftest,makepyfile .. autoclass:: RunResult() :members: .. autoclass:: LineMatcher() :members: pytest-2.8.7/doc/en/usage.rst0000664000175000017500000002046412651247335016441 0ustar ronnyronny00000000000000 .. _usage: Usage and Invocations ========================================== .. _cmdline: Calling pytest through ``python -m pytest`` ----------------------------------------------------- .. versionadded:: 2.0 If you use Python-2.5 or later you can invoke testing through the Python interpreter from the command line:: python -m pytest [...] This is equivalent to invoking the command line script ``py.test [...]`` directly. Getting help on version, option names, environment variables -------------------------------------------------------------- :: py.test --version # shows where pytest was imported from py.test --fixtures # show available builtin function arguments py.test -h | --help # show help on command line and config file options Stopping after the first (or N) failures --------------------------------------------------- To stop the testing process after the first (N) failures:: py.test -x # stop after first failure py.test --maxfail=2 # stop after two failures Specifying tests / selecting tests --------------------------------------------------- Several test run options:: py.test test_mod.py # run tests in module py.test somepath # run all tests below somepath py.test -k stringexpr # only run tests with names that match the # "string expression", e.g. "MyClass and not method" # will select TestMyClass.test_something # but not TestMyClass.test_method_simple py.test test_mod.py::test_func # only run tests that match the "node ID", # e.g "test_mod.py::test_func" will select # only test_func in test_mod.py py.test test_mod.py::TestClass::test_method # run a single method in # a single class Import 'pkg' and use its filesystem location to find and run tests:: py.test --pyargs pkg # run all tests found below directory of pypkg Modifying Python traceback printing ---------------------------------------------- Examples for modifying traceback printing:: py.test --showlocals # show local variables in tracebacks py.test -l # show local variables (shortcut) py.test --tb=long # the default informative traceback formatting py.test --tb=native # the Python standard library formatting py.test --tb=short # a shorter traceback format py.test --tb=line # only one line per failure Dropping to PDB_ (Python Debugger) on failures ----------------------------------------------- .. _PDB: http://docs.python.org/library/pdb.html Python comes with a builtin Python debugger called PDB_. ``pytest`` allows one to drop into the PDB_ prompt via a command line option:: py.test --pdb This will invoke the Python debugger on every failure. Often you might only want to do this for the first failing test to understand a certain failure situation:: py.test -x --pdb # drop to PDB on first failure, then end test session py.test --pdb --maxfail=3 # drop to PDB for first three failures Note that on any failure the exception information is stored on ``sys.last_value``, ``sys.last_type`` and ``sys.last_traceback``. In interactive use, this allows one to drop into postmortem debugging with any debug tool. One can also manually access the exception information, for example:: >>> import sys >>> sys.last_traceback.tb_lineno 42 >>> sys.last_value AssertionError('assert result == "ok"',) Setting a breakpoint / aka ``set_trace()`` ---------------------------------------------------- If you want to set a breakpoint and enter the ``pdb.set_trace()`` you can use a helper:: import pytest def test_function(): ... pytest.set_trace() # invoke PDB debugger and tracing .. versionadded: 2.0.0 Prior to pytest version 2.0.0 you could only enter PDB_ tracing if you disabled capturing on the command line via ``py.test -s``. In later versions, pytest automatically disables its output capture when you enter PDB_ tracing: * Output capture in other tests is not affected. * Any prior test output that has already been captured and will be processed as such. * Any later output produced within the same test will not be captured and will instead get sent directly to ``sys.stdout``. Note that this holds true even for test output occurring after you exit the interactive PDB_ tracing session and continue with the regular test run. .. versionadded: 2.4.0 Since pytest version 2.4.0 you can also use the native Python ``import pdb;pdb.set_trace()`` call to enter PDB_ tracing without having to use the ``pytest.set_trace()`` wrapper or explicitly disable pytest's output capturing via ``py.test -s``. .. _durations: Profiling test execution duration ------------------------------------- .. versionadded: 2.2 To get a list of the slowest 10 test durations:: py.test --durations=10 Creating JUnitXML format files ---------------------------------------------------- To create result files which can be read by Hudson_ or other Continuous integration servers, use this invocation:: py.test --junitxml=path to create an XML file at ``path``. record_xml_property ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. versionadded:: 2.8 If you want to log additional information for a test, you can use the ``record_xml_property`` fixture: .. code-block:: python def test_function(record_xml_property): record_xml_property("example_key", 1) assert 0 This will add an extra property ``example_key="1"`` to the generated ``testcase`` tag: .. code-block:: xml .. warning:: This is an experimental feature, and its interface might be replaced by something more powerful and general in future versions. The functionality per-se will be kept, however. Currently it does not work when used with the ``pytest-xdist`` plugin. Also please note that using this feature will break any schema verification. This might be a problem when used with some CI servers. Creating resultlog format files ---------------------------------------------------- To create plain-text machine-readable result files you can issue:: py.test --resultlog=path and look at the content at the ``path`` location. Such files are used e.g. by the `PyPy-test`_ web page to show test results over several revisions. .. _`PyPy-test`: http://buildbot.pypy.org/summary Sending test report to online pastebin service ----------------------------------------------------- **Creating a URL for each test failure**:: py.test --pastebin=failed This will submit test run information to a remote Paste service and provide a URL for each failure. You may select tests as usual or add for example ``-x`` if you only want to send one particular failure. **Creating a URL for a whole test session log**:: py.test --pastebin=all Currently only pasting to the http://bpaste.net service is implemented. Disabling plugins ----------------- To disable loading specific plugins at invocation time, use the ``-p`` option together with the prefix ``no:``. Example: to disable loading the plugin ``doctest``, which is responsible for executing doctest tests from text files, invoke py.test like this:: py.test -p no:doctest .. _`pytest.main-usage`: Calling pytest from Python code ---------------------------------------------------- .. versionadded:: 2.0 You can invoke ``pytest`` from Python code directly:: pytest.main() this acts as if you would call "py.test" from the command line. It will not raise ``SystemExit`` but return the exitcode instead. You can pass in options and arguments:: pytest.main(['-x', 'mytestdir']) or pass in a string:: pytest.main("-x mytestdir") You can specify additional plugins to ``pytest.main``:: # content of myinvoke.py import pytest class MyPlugin: def pytest_sessionfinish(self): print("*** test run reporting finishing") pytest.main("-qq", plugins=[MyPlugin()]) Running it will show that ``MyPlugin`` was added and its hook was invoked:: $ python myinvoke.py *** test run reporting finishing .. include:: links.inc pytest-2.8.7/doc/en/unittest.rst0000664000175000017500000001700512651247335017211 0ustar ronnyronny00000000000000 .. _`unittest.TestCase`: Support for unittest.TestCase / Integration of fixtures ===================================================================== .. _`unittest.py style`: http://docs.python.org/library/unittest.html ``pytest`` has support for running Python `unittest.py style`_ tests. It's meant for leveraging existing unittest-style projects to use pytest features. Concretely, pytest will automatically collect ``unittest.TestCase`` subclasses and their ``test`` methods in test files. It will invoke typical setup/teardown methods and generally try to make test suites written to run on unittest, to also run using ``pytest``. We assume here that you are familiar with writing ``unittest.TestCase`` style tests and rather focus on integration aspects. Usage ------------------------------------------------------------------- After :ref:`installation` type:: py.test and you should be able to run your unittest-style tests if they are contained in ``test_*`` modules. If that works for you then you can make use of most :ref:`pytest features `, for example ``--pdb`` debugging in failures, using :ref:`plain assert-statements `, :ref:`more informative tracebacks `, stdout-capturing or distributing tests to multiple CPUs via the ``-nNUM`` option if you installed the ``pytest-xdist`` plugin. Please refer to the general ``pytest`` documentation for many more examples. Mixing pytest fixtures into unittest.TestCase style tests ----------------------------------------------------------- Running your unittest with ``pytest`` allows you to use its :ref:`fixture mechanism ` with ``unittest.TestCase`` style tests. Assuming you have at least skimmed the pytest fixture features, let's jump-start into an example that integrates a pytest ``db_class`` fixture, setting up a class-cached database object, and then reference it from a unittest-style test:: # content of conftest.py # we define a fixture function below and it will be "used" by # referencing its name from tests import pytest @pytest.fixture(scope="class") def db_class(request): class DummyDB: pass # set a class attribute on the invoking test context request.cls.db = DummyDB() This defines a fixture function ``db_class`` which - if used - is called once for each test class and which sets the class-level ``db`` attribute to a ``DummyDB`` instance. The fixture function achieves this by receiving a special ``request`` object which gives access to :ref:`the requesting test context ` such as the ``cls`` attribute, denoting the class from which the fixture is used. This architecture de-couples fixture writing from actual test code and allows re-use of the fixture by a minimal reference, the fixture name. So let's write an actual ``unittest.TestCase`` class using our fixture definition:: # content of test_unittest_db.py import unittest import pytest @pytest.mark.usefixtures("db_class") class MyTest(unittest.TestCase): def test_method1(self): assert hasattr(self, "db") assert 0, self.db # fail for demo purposes def test_method2(self): assert 0, self.db # fail for demo purposes The ``@pytest.mark.usefixtures("db_class")`` class-decorator makes sure that the pytest fixture function ``db_class`` is called once per class. Due to the deliberately failing assert statements, we can take a look at the ``self.db`` values in the traceback:: $ py.test test_unittest_db.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_unittest_db.py FF ======= FAILURES ======== _______ MyTest.test_method1 ________ self = def test_method1(self): assert hasattr(self, "db") > assert 0, self.db # fail for demo purposes E AssertionError: .DummyDB object at 0xdeadbeef> E assert 0 test_unittest_db.py:9: AssertionError _______ MyTest.test_method2 ________ self = def test_method2(self): > assert 0, self.db # fail for demo purposes E AssertionError: .DummyDB object at 0xdeadbeef> E assert 0 test_unittest_db.py:12: AssertionError ======= 2 failed in 0.12 seconds ======== This default pytest traceback shows that the two test methods share the same ``self.db`` instance which was our intention when writing the class-scoped fixture function above. autouse fixtures and accessing other fixtures ------------------------------------------------------------------- Although it's usually better to explicitly declare use of fixtures you need for a given test, you may sometimes want to have fixtures that are automatically used in a given context. After all, the traditional style of unittest-setup mandates the use of this implicit fixture writing and chances are, you are used to it or like it. You can flag fixture functions with ``@pytest.fixture(autouse=True)`` and define the fixture function in the context where you want it used. Let's look at an ``initdir`` fixture which makes all test methods of a ``TestCase`` class execute in a temporary directory with a pre-initialized ``samplefile.ini``. Our ``initdir`` fixture itself uses the pytest builtin :ref:`tmpdir ` fixture to delegate the creation of a per-test temporary directory:: # content of test_unittest_cleandir.py import pytest import unittest class MyTest(unittest.TestCase): @pytest.fixture(autouse=True) def initdir(self, tmpdir): tmpdir.chdir() # change to pytest-provided temporary directory tmpdir.join("samplefile.ini").write("# testdata") def test_method(self): s = open("samplefile.ini").read() assert "testdata" in s Due to the ``autouse`` flag the ``initdir`` fixture function will be used for all methods of the class where it is defined. This is a shortcut for using a ``@pytest.mark.usefixtures("initdir")`` marker on the class like in the previous example. Running this test module ...:: $ py.test -q test_unittest_cleandir.py . 1 passed in 0.12 seconds ... gives us one passed test because the ``initdir`` fixture function was executed ahead of the ``test_method``. .. note:: While pytest supports receiving fixtures via :ref:`test function arguments ` for non-unittest test methods, ``unittest.TestCase`` methods cannot directly receive fixture function arguments as implementing that is likely to inflict on the ability to run general unittest.TestCase test suites. Maybe optional support would be possible, though. If unittest finally grows a plugin system that should help as well. In the meanwhile, the above ``usefixtures`` and ``autouse`` examples should help to mix in pytest fixtures into unittest suites. And of course you can also start to selectively leave away the ``unittest.TestCase`` subclassing, use plain asserts and get the unlimited pytest feature set. Converting from unittest to pytest --------------------------------------- If you want to convert your unittest testcases to pytest, there are some helpers like `unittest2pytest `__, which uses lib2to3 and introspection for the transformation. pytest-2.8.7/doc/en/tmpdir.rst0000664000175000017500000000641012651247335016627 0ustar ronnyronny00000000000000 .. _`tmpdir handling`: .. _tmpdir: Temporary directories and files ================================================ The 'tmpdir' fixture -------------------- You can use the ``tmpdir`` fixture which will provide a temporary directory unique to the test invocation, created in the `base temporary directory`_. ``tmpdir`` is a `py.path.local`_ object which offers ``os.path`` methods and more. Here is an example test usage:: # content of test_tmpdir.py import os def test_create_file(tmpdir): p = tmpdir.mkdir("sub").join("hello.txt") p.write("content") assert p.read() == "content" assert len(tmpdir.listdir()) == 1 assert 0 Running this would result in a passed test except for the last ``assert 0`` line which we use to look at values:: $ py.test test_tmpdir.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_tmpdir.py F ======= FAILURES ======== _______ test_create_file ________ tmpdir = local('PYTEST_TMPDIR/test_create_file0') def test_create_file(tmpdir): p = tmpdir.mkdir("sub").join("hello.txt") p.write("content") assert p.read() == "content" assert len(tmpdir.listdir()) == 1 > assert 0 E assert 0 test_tmpdir.py:7: AssertionError ======= 1 failed in 0.12 seconds ======== The 'tmpdir_factory' fixture ---------------------------- .. versionadded:: 2.8 The ``tmpdir_factory`` is a session-scoped fixture which can be used to create arbitrary temporary directories from any other fixture or test. For example, suppose your test suite needs a large image on disk, which is generated procedurally. Instead of computing the same image for each test that uses it into its own ``tmpdir``, you can generate it once per-session to save time: .. code-block:: python # contents of conftest.py import pytest @pytest.fixture(scope='session') def image_file(tmpdir_factory): img = compute_expensive_image() fn = tmpdir_factory.mktemp('data').join('img.png') img.save(str(fn)) return fn # contents of test_image.py def test_histogram(image_file): img = load_image(image_file) # compute and test histogram ``tmpdir_factory`` instances have the following methods: .. currentmodule:: _pytest.tmpdir .. automethod:: TempdirFactory.mktemp .. automethod:: TempdirFactory.getbasetemp .. _`base temporary directory`: The default base temporary directory ----------------------------------------------- Temporary directories are by default created as sub-directories of the system temporary directory. The base name will be ``pytest-NUM`` where ``NUM`` will be incremented with each test run. Moreover, entries older than 3 temporary directories will be removed. You can override the default temporary directory setting like this:: py.test --basetemp=mydir When distributing tests on the local machine, ``pytest`` takes care to configure a basetemp directory for the sub processes such that all temporary data lands below a single per-test run basetemp directory. .. _`py.path.local`: http://py.rtfd.org/en/latest/path.html pytest-2.8.7/doc/en/talks.rst0000664000175000017500000001241612651247335016451 0ustar ronnyronny00000000000000 Talks and Tutorials ========================== .. sidebar:: Next Open Trainings `professional testing with pytest and tox `_, 24-26th November 2014, Freiburg, Germany .. _`funcargs`: funcargs.html Talks and blog postings --------------------------------------------- .. _`tutorial1 repository`: http://bitbucket.org/pytest-dev/pytest-tutorial1/ .. _`pycon 2010 tutorial PDF`: http://bitbucket.org/pytest-dev/pytest-tutorial1/raw/tip/pytest-basic.pdf -

A *skip* means that you expect your test to pass unless the environment (e.g. wrong Python interpreter, missing dependency) prevents it to run. And *xfail* means that your test can run but you expect it to fail because there is an implementation problem. ``pytest`` counts and lists *skip* and *xfail* tests separately. Detailed information about skipped/xfailed tests is not shown by default to avoid cluttering the output. You can use the ``-r`` option to see details corresponding to the "short" letters shown in the test progress:: py.test -rxs # show extra info on skips and xfails (See :ref:`how to change command line options defaults`) .. _skipif: .. _`condition booleans`: Marking a test function to be skipped ------------------------------------------- .. versionadded:: 2.0, 2.4 Here is an example of marking a test function to be skipped when run on a Python3.3 interpreter:: import sys @pytest.mark.skipif(sys.version_info < (3,3), reason="requires python3.3") def test_function(): ... During test function setup the condition ("sys.version_info >= (3,3)") is checked. If it evaluates to True, the test function will be skipped with the specified reason. Note that pytest enforces specifying a reason in order to report meaningful "skip reasons" (e.g. when using ``-rs``). If the condition is a string, it will be evaluated as python expression. You can share skipif markers between modules. Consider this test module:: # content of test_mymodule.py import mymodule minversion = pytest.mark.skipif(mymodule.__versioninfo__ < (1,1), reason="at least mymodule-1.1 required") @minversion def test_function(): ... You can import it from another test module:: # test_myothermodule.py from test_mymodule import minversion @minversion def test_anotherfunction(): ... For larger test suites it's usually a good idea to have one file where you define the markers which you then consistently apply throughout your test suite. Alternatively, the pre pytest-2.4 way to specify :ref:`condition strings ` instead of booleans will remain fully supported in future versions of pytest. It couldn't be easily used for importing markers between test modules so it's no longer advertised as the primary method. Skip all test functions of a class or module --------------------------------------------- As with all function :ref:`marking ` you can skip test functions at the `whole class- or module level`_. If your code targets python2.6 or above you use the skipif decorator (and any other marker) on classes:: @pytest.mark.skipif(sys.platform == 'win32', reason="does not run on windows") class TestPosixCalls: def test_function(self): "will not be setup or run under 'win32' platform" If the condition is true, this marker will produce a skip result for each of the test methods. If your code targets python2.5 where class-decorators are not available, you can set the ``pytestmark`` attribute of a class:: class TestPosixCalls: pytestmark = pytest.mark.skipif(sys.platform == 'win32', reason="does not run on windows") def test_function(self): "will not be setup or run under 'win32' platform" As with the class-decorator, the ``pytestmark`` special name tells ``pytest`` to apply it to each test function in the class. If you want to skip all test functions of a module, you must use the ``pytestmark`` name on the global level: .. code-block:: python # test_module.py pytestmark = pytest.mark.skipif(...) If multiple "skipif" decorators are applied to a test function, it will be skipped if any of the skip conditions is true. .. _`whole class- or module level`: mark.html#scoped-marking .. _xfail: Mark a test function as expected to fail ------------------------------------------------------- You can use the ``xfail`` marker to indicate that you expect the test to fail:: @pytest.mark.xfail def test_function(): ... This test will be run but no traceback will be reported when it fails. Instead terminal reporting will list it in the "expected to fail" or "unexpectedly passing" sections. By specifying on the commandline:: pytest --runxfail you can force the running and reporting of an ``xfail`` marked test as if it weren't marked at all. As with skipif_ you can also mark your expectation of a failure on a particular platform:: @pytest.mark.xfail(sys.version_info >= (3,3), reason="python3.3 api changes") def test_function(): ... If you want to be more specific as to why the test is failing, you can specify a single exception, or a list of exceptions, in the ``raises`` argument. Then the test will be reported as a regular failure if it fails with an exception not mentioned in ``raises``. You can furthermore prevent the running of an "xfail" test or specify a reason such as a bug ID or similar. Here is a simple test file with the several usages: .. literalinclude:: example/xfail_demo.py Running it with the report-on-xfail option gives this output:: example $ py.test -rx xfail_demo.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR/example, inifile: collected 7 items xfail_demo.py xxxxxxx ======= short test summary info ======== XFAIL xfail_demo.py::test_hello XFAIL xfail_demo.py::test_hello2 reason: [NOTRUN] XFAIL xfail_demo.py::test_hello3 condition: hasattr(os, 'sep') XFAIL xfail_demo.py::test_hello4 bug 110 XFAIL xfail_demo.py::test_hello5 condition: pytest.__version__[0] != "17" XFAIL xfail_demo.py::test_hello6 reason: reason XFAIL xfail_demo.py::test_hello7 ======= 7 xfailed in 0.12 seconds ======== .. _`skip/xfail with parametrize`: Skip/xfail with parametrize --------------------------- It is possible to apply markers like skip and xfail to individual test instances when using parametrize:: import pytest @pytest.mark.parametrize(("n", "expected"), [ (1, 2), pytest.mark.xfail((1, 0)), pytest.mark.xfail(reason="some bug")((1, 3)), (2, 3), (3, 4), (4, 5), pytest.mark.skipif("sys.version_info >= (3,0)")((10, 11)), ]) def test_increment(n, expected): assert n + 1 == expected Imperative xfail from within a test or setup function ------------------------------------------------------ If you cannot declare xfail- of skipif conditions at import time you can also imperatively produce an according outcome imperatively, in test or setup code:: def test_function(): if not valid_config(): pytest.xfail("failing configuration (but should work)") # or pytest.skip("unsupported configuration") Skipping on a missing import dependency -------------------------------------------------- You can use the following import helper at module level or within a test or test setup function:: docutils = pytest.importorskip("docutils") If ``docutils`` cannot be imported here, this will lead to a skip outcome of the test. You can also skip based on the version number of a library:: docutils = pytest.importorskip("docutils", minversion="0.3") The version will be read from the specified module's ``__version__`` attribute. .. _string conditions: specifying conditions as strings versus booleans ---------------------------------------------------------- Prior to pytest-2.4 the only way to specify skipif/xfail conditions was to use strings:: import sys @pytest.mark.skipif("sys.version_info >= (3,3)") def test_function(): ... During test function setup the skipif condition is evaluated by calling ``eval('sys.version_info >= (3,0)', namespace)``. The namespace contains all the module globals, and ``os`` and ``sys`` as a minimum. Since pytest-2.4 `condition booleans`_ are considered preferable because markers can then be freely imported between test modules. With strings you need to import not only the marker but all variables everything used by the marker, which violates encapsulation. The reason for specifying the condition as a string was that ``pytest`` can report a summary of skip conditions based purely on the condition string. With conditions as booleans you are required to specify a ``reason`` string. Note that string conditions will remain fully supported and you are free to use them if you have no need for cross-importing markers. The evaluation of a condition string in ``pytest.mark.skipif(conditionstring)`` or ``pytest.mark.xfail(conditionstring)`` takes place in a namespace dictionary which is constructed as follows: * the namespace is initialized by putting the ``sys`` and ``os`` modules and the pytest ``config`` object into it. * updated with the module globals of the test function for which the expression is applied. The pytest ``config`` object allows you to skip based on a test configuration value which you might have added:: @pytest.mark.skipif("not config.getvalue('db')") def test_function(...): ... The equivalent with "boolean conditions" is:: @pytest.mark.skipif(not pytest.config.getvalue("db"), reason="--db was not specified") def test_function(...): pass .. note:: You cannot use ``pytest.config.getvalue()`` in code imported before py.test's argument parsing takes place. For example, ``conftest.py`` files are imported before command line parsing and thus ``config.getvalue()`` will not execute correctly. pytest-2.8.7/doc/en/setup.rst0000664000175000017500000000046612651247335016475 0ustar ronnyronny00000000000000 setup: is now an "autouse fixture" ======================================================== During development prior to the pytest-2.3 release the name ``pytest.setup`` was used but before the release it was renamed and moved to become part of the general fixture mechanism, namely :ref:`autouse fixtures` pytest-2.8.7/doc/en/recwarn.rst0000664000175000017500000000773112651247335017000 0ustar ronnyronny00000000000000 Asserting Warnings ===================================================== .. _warns: Asserting warnings with the warns function ----------------------------------------------- .. versionadded:: 2.8 You can check that code raises a particular warning using ``pytest.warns``, which works in a similar manner to :ref:`raises `:: import warnings import pytest def test_warning(): with pytest.warns(UserWarning): warnings.warn("my warning", UserWarning) The test will fail if the warning in question is not raised. You can also call ``pytest.warns`` on a function or code string:: pytest.warns(expected_warning, func, *args, **kwargs) pytest.warns(expected_warning, "func(*args, **kwargs)") The function also returns a list of all raised warnings (as ``warnings.WarningMessage`` objects), which you can query for additional information:: with pytest.warns(RuntimeWarning) as record: warnings.warn("another warning", RuntimeWarning) # check that only one warning was raised assert len(record) == 1 # check that the message matches assert record[0].message.args[0] == "another warning" Alternatively, you can examine raised warnings in detail using the :ref:`recwarn ` fixture (see below). .. note:: ``DeprecationWarning`` and ``PendingDeprecationWarning`` are treated differently; see :ref:`ensuring_function_triggers`. .. _recwarn: Recording warnings ------------------------ You can record raised warnings either using ``pytest.warns`` or with the ``recwarn`` fixture. To record with ``pytest.warns`` without asserting anything about the warnings, pass ``None`` as the expected warning type:: with pytest.warns(None) as record: warnings.warn("user", UserWarning) warnings.warn("runtime", RuntimeWarning) assert len(record) == 2 assert str(record[0].message) == "user" assert str(record[1].message) == "runtime" The ``recwarn`` fixture will record warnings for the whole function:: import warnings def test_hello(recwarn): warnings.warn("hello", UserWarning) assert len(recwarn) == 1 w = recwarn.pop(UserWarning) assert issubclass(w.category, UserWarning) assert str(w.message) == "hello" assert w.filename assert w.lineno Both ``recwarn`` and ``pytest.warns`` return the same interface for recorded warnings: a WarningsRecorder instance. To view the recorded warnings, you can iterate over this instance, call ``len`` on it to get the number of recorded warnings, or index into it to get a particular recorded warning. It also provides these methods: .. autoclass:: _pytest.recwarn.WarningsRecorder() :members: Each recorded warning has the attributes ``message``, ``category``, ``filename``, ``lineno``, ``file``, and ``line``. The ``category`` is the class of the warning. The ``message`` is the warning itself; calling ``str(message)`` will return the actual message of the warning. .. note:: ``DeprecationWarning`` and ``PendingDeprecationWarning`` are treated differently; see :ref:`ensuring_function_triggers`. .. _ensuring_function_triggers: Ensuring a function triggers a deprecation warning ------------------------------------------------------- You can also call a global helper for checking that a certain function call triggers a ``DeprecationWarning`` or ``PendingDeprecationWarning``:: import pytest def test_global(): pytest.deprecated_call(myfunction, 17) By default, ``DeprecationWarning`` and ``PendingDeprecationWarning`` will not be caught when using ``pytest.warns`` or ``recwarn`` because default Python warnings filters hide them.

For writing your own plugins, please refer to :ref:`writing-plugins`. Installing a third party plugin can be easily done with ``pip``:: pip install pytest-NAME pip uninstall pytest-NAME If a plugin is installed, ``pytest`` automatically finds and integrates it, there is no need to activate it. Here is a little annotated list for some popular plugins: .. _`django`: https://www.djangoproject.com/ * `pytest-django `_: write tests for `django`_ apps, using pytest integration. * `pytest-twisted `_: write tests for `twisted `_ apps, starting a reactor and processing deferreds from test functions. * `pytest-catchlog `_: to capture and assert about messages from the logging module * `pytest-cov `_: coverage reporting, compatible with distributed testing * `pytest-xdist `_: to distribute tests to CPUs and remote hosts, to run in boxed mode which allows to survive segmentation faults, to run in looponfailing mode, automatically re-running failing tests on file changes, see also :ref:`xdist` * `pytest-instafail `_: to report failures while the test run is happening. * `pytest-bdd `_ and `pytest-konira `_ to write tests using behaviour-driven testing. * `pytest-timeout `_: to timeout tests based on function marks or global definitions. * `pytest-pep8 `_: a ``--pep8`` option to enable PEP8 compliance checking. * `pytest-flakes `_: check source code with pyflakes. * `oejskit `_: a plugin to run javascript unittests in live browsers. To see a complete list of all plugins with their latest testing status against different py.test and Python versions, please visit `plugincompat `_. You may also discover more plugins through a `pytest- pypi.python.org search`_. .. _`available installable plugins`: .. _`pytest- pypi.python.org search`: http://pypi.python.org/pypi?%3Aaction=search&term=pytest-&submit=search Requiring/Loading plugins in a test module or conftest file ----------------------------------------------------------- You can require plugins in a test module or a conftest file like this:: pytest_plugins = "myapp.testsupport.myplugin", When the test module or conftest plugin is loaded the specified plugins will be loaded as well. pytest_plugins = "myapp.testsupport.myplugin" which will import the specified module as a ``pytest`` plugin. .. _`findpluginname`: Finding out which plugins are active ------------------------------------ If you want to find out which plugins are active in your environment you can type:: py.test --traceconfig and will get an extended test header which shows activated plugins and their names. It will also print local plugins aka :ref:`conftest.py ` files when they are loaded. .. _`cmdunregister`: Deactivating / unregistering a plugin by name --------------------------------------------- You can prevent plugins from loading or unregister them:: py.test -p no:NAME This means that any subsequent try to activate/load the named plugin will not work. If you want to unconditionally disable a plugin for a project, you can add this option to your ``pytest.ini`` file: .. code-block:: ini [pytest] addopts = -p no:NAME Alternatively to disable it only in certain environments (for example in a CI server), you can set ``PYTEST_ADDOPTS`` environment variable to ``-p no:name``. See :ref:`findpluginname` for how to obtain the name of a plugin. .. _`builtin plugins`: Pytest default plugin reference ------------------------------- You can find the source code for the following plugins in the `pytest repository `_. .. autosummary:: _pytest.assertion _pytest.cacheprovider _pytest.capture _pytest.config _pytest.doctest _pytest.genscript _pytest.helpconfig _pytest.junitxml _pytest.mark _pytest.monkeypatch _pytest.nose _pytest.pastebin _pytest.pdb _pytest.pytester _pytest.python _pytest.recwarn _pytest.resultlog _pytest.runner _pytest.main _pytest.skipping _pytest.terminal _pytest.tmpdir _pytest.unittest pytest-2.8.7/doc/en/parametrize.rst0000664000175000017500000001610112651247335017651 0ustar ronnyronny00000000000000 .. _`test generators`: .. _`parametrizing-tests`: .. _`parametrized test functions`: .. _`parametrize`: .. _`parametrize-basics`: Parametrizing fixtures and test functions ========================================================================== pytest supports test parametrization in several well-integrated ways: - :py:func:`pytest.fixture` allows to define :ref:`parametrization at the level of fixture functions `. * `@pytest.mark.parametrize`_ allows to define parametrization at the function or class level, provides multiple argument/fixture sets for a particular test function or class. * `pytest_generate_tests`_ enables implementing your own custom dynamic parametrization scheme or extensions. .. _parametrizemark: .. _`@pytest.mark.parametrize`: ``@pytest.mark.parametrize``: parametrizing test functions --------------------------------------------------------------------- .. regendoc: wipe .. versionadded:: 2.2 .. versionchanged:: 2.4 Several improvements. The builtin ``pytest.mark.parametrize`` decorator enables parametrization of arguments for a test function. Here is a typical example of a test function that implements checking that a certain input leads to an expected output:: # content of test_expectation.py import pytest @pytest.mark.parametrize("test_input,expected", [ ("3+5", 8), ("2+4", 6), ("6*9", 42), ]) def test_eval(test_input, expected): assert eval(test_input) == expected Here, the ``@parametrize`` decorator defines three different ``(test_input,expected)`` tuples so that the ``test_eval`` function will run three times using them in turn:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 3 items test_expectation.py ..F ======= FAILURES ======== _______ test_eval[6*9-42] ________ test_input = '6*9', expected = 42 @pytest.mark.parametrize("test_input,expected", [ ("3+5", 8), ("2+4", 6), ("6*9", 42), ]) def test_eval(test_input, expected): > assert eval(test_input) == expected E assert 54 == 42 E + where 54 = eval('6*9') test_expectation.py:8: AssertionError ======= 1 failed, 2 passed in 0.12 seconds ======== As designed in this example, only one pair of input/output values fails the simple test function. And as usual with test function arguments, you can see the ``input`` and ``output`` values in the traceback. Note that you could also use the parametrize marker on a class or a module (see :ref:`mark`) which would invoke several functions with the argument sets. It is also possible to mark individual test instances within parametrize, for example with the builtin ``mark.xfail``:: # content of test_expectation.py import pytest @pytest.mark.parametrize("test_input,expected", [ ("3+5", 8), ("2+4", 6), pytest.mark.xfail(("6*9", 42)), ]) def test_eval(test_input, expected): assert eval(test_input) == expected Let's run this:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 3 items test_expectation.py ..x ======= 2 passed, 1 xfailed in 0.12 seconds ======== The one parameter set which caused a failure previously now shows up as an "xfailed (expected to fail)" test. To get all combinations of multiple parametrized arguments you can stack ``parametrize`` decorators:: import pytest @pytest.mark.parametrize("x", [0, 1]) @pytest.mark.parametrize("y", [2, 3]) def test_foo(x, y): pass This will run the test with the arguments set to x=0/y=2, x=0/y=3, x=1/y=2 and x=1/y=3. .. note:: In versions prior to 2.4 one needed to specify the argument names as a tuple. This remains valid but the simpler ``"name1,name2,..."`` comma-separated-string syntax is now advertised first because it's easier to write and produces less line noise. .. _`pytest_generate_tests`: Basic ``pytest_generate_tests`` example --------------------------------------------- Sometimes you may want to implement your own parametrization scheme or implement some dynamism for determining the parameters or scope of a fixture. For this, you can use the ``pytest_generate_tests`` hook which is called when collecting a test function. Through the passed in `metafunc` object you can inspect the requesting test context and, most importantly, you can call ``metafunc.parametrize()`` to cause parametrization. For example, let's say we want to run a test taking string inputs which we want to set via a new ``pytest`` command line option. Let's first write a simple test accepting a ``stringinput`` fixture function argument:: # content of test_strings.py def test_valid_string(stringinput): assert stringinput.isalpha() Now we add a ``conftest.py`` file containing the addition of a command line option and the parametrization of our test function:: # content of conftest.py def pytest_addoption(parser): parser.addoption("--stringinput", action="append", default=[], help="list of stringinputs to pass to test functions") def pytest_generate_tests(metafunc): if 'stringinput' in metafunc.fixturenames: metafunc.parametrize("stringinput", metafunc.config.option.stringinput) If we now pass two stringinput values, our test will run twice:: $ py.test -q --stringinput="hello" --stringinput="world" test_strings.py .. 2 passed in 0.12 seconds Let's also run with a stringinput that will lead to a failing test:: $ py.test -q --stringinput="!" test_strings.py F ======= FAILURES ======== _______ test_valid_string[!] ________ stringinput = '!' def test_valid_string(stringinput): > assert stringinput.isalpha() E assert () E + where = '!'.isalpha test_strings.py:3: AssertionError 1 failed in 0.12 seconds As expected our test function fails. If you don't specify a stringinput it will be skipped because ``metafunc.parametrize()`` will be called with an empty parameter list:: $ py.test -q -rs test_strings.py s ======= short test summary info ======== SKIP [1] $PYTHON_PREFIX/lib/python3.4/site-packages/_pytest/python.py:1417: got empty parameter set, function test_valid_string at $REGENDOC_TMPDIR/test_strings.py:1 1 skipped in 0.12 seconds For further examples, you might want to look at :ref:`more parametrization examples `. .. _`metafunc object`: The **metafunc** object ------------------------------------------- .. currentmodule:: _pytest.python .. autoclass:: Metafunc .. automethod:: Metafunc.parametrize .. automethod:: Metafunc.addcall(funcargs=None,id=_notexists,param=_notexists) pytest-2.8.7/doc/en/overview.rst0000664000175000017500000000033512651247335017176 0ustar ronnyronny00000000000000================================================== Getting started basics ================================================== .. toctree:: :maxdepth: 2 getting-started usage goodpractices projects faq pytest-2.8.7/doc/en/nose.rst0000664000175000017500000000376612651247335016307 0ustar ronnyronny00000000000000Running tests written for nose ======================================= .. include:: links.inc ``pytest`` has basic support for running tests written for nose_. .. _nosestyle: Usage ------------- After :ref:`installation` type:: python setup.py develop # make sure tests can import our package py.test # instead of 'nosetests' and you should be able to run your nose style tests and make use of pytest's capabilities.

As nose and pytest already both support ``setup_class, teardown_class, setup_method, teardown_method`` it doesn't seem useful to duplicate the unittest-API like nose does. If you however rather think pytest should support the unittest-spelling on plain classes please post `to this issue `_. - nose imports test modules with the same import path (e.g. ``tests.test_mod``) but different file system paths (e.g. ``tests/test_mode.py`` and ``other/tests/test_mode.py``) by extending sys.path/import semantics. pytest does not do that but there is discussion in `issue268 `_ for adding some support. Note that `nose2 choose to avoid this sys.path/import hackery `_. - nose-style doctests are not collected and executed correctly, also doctest fixtures don't work. - no nose-configuration is recognized pytest-2.8.7/doc/en/naming20.rst0000664000175000017500000000131612651247335016743 0ustar ronnyronny00000000000000 .. _naming20: New pytest names in 2.0 (flat is better than nested) ---------------------------------------------------- If you used older version of the ``py`` distribution (which included the py.test command line tool and Python name space) you accessed helpers and possibly collection classes through the ``py.test`` Python namespaces. The new ``pytest`` Python module flaty provides the same objects, following these renaming rules:: py.test.XYZ -> pytest.XYZ py.test.collect.XYZ -> pytest.XYZ py.test.cmdline.main -> pytest.main The old ``py.test.*`` ways to access functionality remain valid but you are encouraged to do global renaming according to the above rules in your test code. pytest-2.8.7/doc/en/monkeypatch.rst0000664000175000017500000000566112651247335017661 0ustar ronnyronny00000000000000 Monkeypatching/mocking modules and environments ================================================================ .. currentmodule:: _pytest.monkeypatch Sometimes tests need to invoke functionality which depends on global settings or which invokes code which cannot be easily tested such as network access. The ``monkeypatch`` function argument helps you to safely set/delete an attribute, dictionary item or environment variable or to modify ``sys.path`` for importing. See the `monkeypatch blog post`_ for some introduction material and a discussion of its motivation. .. _`monkeypatch blog post`: http://tetamap.wordpress.com/2009/03/03/monkeypatching-in-unit-tests-done-right/ Simple example: monkeypatching functions --------------------------------------------------- If you want to pretend that ``os.expanduser`` returns a certain directory, you can use the :py:meth:`monkeypatch.setattr` method to patch this function before calling into a function which uses it:: # content of test_module.py import os.path def getssh(): # pseudo application code return os.path.join(os.path.expanduser("~admin"), '.ssh') def test_mytest(monkeypatch): def mockreturn(path): return '/abc' monkeypatch.setattr(os.path, 'expanduser', mockreturn) x = getssh() assert x == '/abc/.ssh' Here our test function monkeypatches ``os.path.expanduser`` and then calls into an function that calls it. After the test function finishes the ``os.path.expanduser`` modification will be undone. example: preventing "requests" from remote operations ------------------------------------------------------ If you want to prevent the "requests" library from performing http requests in all your tests, you can do:: # content of conftest.py import pytest @pytest.fixture(autouse=True) def no_requests(monkeypatch): monkeypatch.delattr("requests.sessions.Session.request") This autouse fixture will be executed for each test function and it will delete the method ``request.session.Session.request`` so that any attempts within tests to create http requests will fail. example: setting an attribute on some class ------------------------------------------------------ If you need to patch out ``os.getcwd()`` to return an artificial value:: def test_some_interaction(monkeypatch): monkeypatch.setattr("os.getcwd", lambda: "/") which is equivalent to the long form:: def test_some_interaction(monkeypatch): import os monkeypatch.setattr(os, "getcwd", lambda: "/") Method reference of the monkeypatch function argument ----------------------------------------------------- .. autoclass:: monkeypatch :members: setattr, replace, delattr, setitem, delitem, setenv, delenv, syspath_prepend, chdir, undo ``monkeypatch.setattr/delattr/delitem/delenv()`` all by default raise an Exception if the target does not exist.

There are some builtin markers, for example: * :ref:`skipif ` - skip a test function if a certain condition is met * :ref:`xfail ` - produce an "expected failure" outcome if a certain condition is met * :ref:`parametrize ` to perform multiple calls to the same test function. It's easy to create custom markers or to apply markers to whole test classes or modules.

Alternatively, command line arguments can be used in any combination of directories, file names or node ids. * recurse into directories, unless they match :confval:`norecursedirs` * ``test_*.py`` or ``*_test.py`` files, imported by their `test package name`_. * ``Test`` prefixed test classes (without an ``__init__`` method) * ``test_`` prefixed test functions or methods are test items For examples of how to customize your test discovery :doc:`example/pythoncollection`. Within Python modules, ``pytest`` also discovers tests using the standard :ref:`unittest.TestCase ` subclassing technique. Choosing a test layout / import rules ------------------------------------------ ``pytest`` supports two common test layouts: * putting tests into an extra directory outside your actual application code, useful if you have many functional tests or for other reasons want to keep tests separate from actual application code (often a good idea):: setup.py # your setuptools Python package metadata mypkg/ __init__.py appmodule.py tests/ test_app.py ... * inlining test directories into your application package, useful if you have direct relation between (unit-)test and application modules and want to distribute your tests along with your application:: setup.py # your setuptools Python package metadata mypkg/ __init__.py appmodule.py ... test/ test_app.py ... Important notes relating to both schemes: - **make sure that "mypkg" is importable**, for example by typing once:: pip install -e . # install package using setup.py in editable mode - **avoid "__init__.py" files in your test directories**. This way your tests can run easily against an installed version of ``mypkg``, independently from the installed package if it contains the tests or not. - With inlined tests you might put ``__init__.py`` into test directories and make them installable as part of your application. Using the ``py.test --pyargs mypkg`` invocation pytest will discover where mypkg is installed and collect tests from there. With the "external" test you can still distribute tests but they will not be installed or become importable. Typically you can run tests by pointing to test directories or modules:: py.test tests/test_app.py # for external test dirs py.test mypkg/test/test_app.py # for inlined test dirs py.test mypkg # run tests in all below test directories py.test # run all tests below current dir ... Because of the above ``editable install`` mode you can change your source code (both tests and the app) and rerun tests at will. Once you are done with your work, you can `use tox`_ to make sure that the package is really correct and tests pass in all required configurations. .. note:: You can use Python3 namespace packages (PEP420) for your application but pytest will still perform `test package name`_ discovery based on the presence of ``__init__.py`` files. If you use one of the two recommended file system layouts above but leave away the ``__init__.py`` files from your directories it should just work on Python3.3 and above. From "inlined tests", however, you will need to use absolute imports for getting at your application code. .. _`test package name`: .. note:: If ``pytest`` finds a "a/b/test_module.py" test file while recursing into the filesystem it determines the import name as follows: * determine ``basedir``: this is the first "upward" (towards the root) directory not containing an ``__init__.py``. If e.g. both ``a`` and ``b`` contain an ``__init__.py`` file then the parent directory of ``a`` will become the ``basedir``. * perform ``sys.path.insert(0, basedir)`` to make the test module importable under the fully qualified import name. * ``import a.b.test_module`` where the path is determined by converting path separators ``/`` into "." characters. This means you must follow the convention of having directory and file names map directly to the import names. The reason for this somewhat evolved importing technique is that in larger projects multiple test modules might import from each other and thus deriving a canonical import name helps to avoid surprises such as a test modules getting imported twice. .. _`virtualenv`: http://pypi.python.org/pypi/virtualenv .. _`buildout`: http://www.buildout.org/ .. _pip: http://pypi.python.org/pypi/pip .. _`use tox`: Tox ------ For development, we recommend to use virtualenv_ environments and pip_ for installing your application and any dependencies as well as the ``pytest`` package itself. This ensures your code and dependencies are isolated from the system Python installation. If you frequently release code and want to make sure that your actual package passes all tests you may want to look into `tox`_, the virtualenv test automation tool and its `pytest support `_. Tox helps you to setup virtualenv environments with pre-defined dependencies and then executing a pre-configured test command with options. It will run tests against the installed package and not against your source code checkout, helping to detect packaging glitches. Continuous integration services such as Jenkins_ can make use of the ``--junitxml=PATH`` option to create a JUnitXML file and generate reports. Integrating with setuptools / ``python setup.py test`` / ``pytest-runner`` -------------------------------------------------------------------------- You can integrate test runs into your setuptools based project with the `pytest-runner `_ plugin. Add this to ``setup.py`` file: .. code-block:: python from setuptools import setup setup( #..., setup_requires=['pytest-runner', ...], tests_require=['pytest', ...], #..., ) And create an alias into ``setup.cfg`` file: .. code-block:: ini [aliases] test=pytest If you now type:: python setup.py test this will execute your tests using ``pytest-runner``. As this is a standalone version of ``pytest`` no prior installation whatsoever is required for calling the test command. You can also pass additional arguments to py.test such as your test directory or other options using ``--addopts``. Manual Integration ^^^^^^^^^^^^^^^^^^ If for some reason you don't want/can't use ``pytest-runner``, you can write your own setuptools Test command for invoking pytest. .. code-block:: python import sys from setuptools.command.test import test as TestCommand class PyTest(TestCommand): user_options = [('pytest-args=', 'a', "Arguments to pass to py.test")] def initialize_options(self): TestCommand.initialize_options(self) self.pytest_args = [] def run_tests(self): #import here, cause outside the eggs aren't loaded import pytest errno = pytest.main(self.pytest_args) sys.exit(errno) setup( #..., tests_require=['pytest'], cmdclass = {'test': PyTest}, ) Now if you run:: python setup.py test this will download ``pytest`` if needed and then run your tests as you would expect it to. You can pass a single string of arguments using the ``--pytest-args`` or ``-a`` command-line option. For example:: python setup.py test -a "--durations=5" is equivalent to running ``py.test --durations=5``. .. _standalone: .. _`genscript method`: (deprecated) Create a pytest standalone script ----------------------------------------------- .. deprecated:: 2.8 .. note:: ``genscript`` has been deprecated because: * It cannot support plugins, rendering its usefulness extremely limited; * Tooling has become much better since ``genscript`` was introduced; * It is possible to build a zipped ``pytest`` application without the shortcomings above. There's no planned version in which this command will be removed at the moment of this writing, but its use is discouraged for new applications. If you are a maintainer or application developer and want people who don't deal with python much to easily run tests you may generate a standalone ``pytest`` script:: py.test --genscript=runtests.py This generates a ``runtests.py`` script which is a fully functional basic ``pytest`` script, running unchanged under Python2 and Python3. You can tell people to download the script and then e.g. run it like this:: python runtests.py .. include:: links.inc pytest-2.8.7/doc/en/getting-started.rst0000664000175000017500000001654112651247335020443 0ustar ronnyronny00000000000000Installation and Getting Started =================================== **Pythons**: Python 2.6,2.7,3.3,3.4,3.5, Jython, PyPy-2.3 **Platforms**: Unix/Posix and Windows **PyPI package name**: `pytest `_ **dependencies**: `py `_, `colorama (Windows) `_, `argparse (py26) `_. **documentation as PDF**: `download latest `_ .. _`getstarted`: .. _installation: Installation ---------------------------------------- Installation options:: pip install -U pytest # or easy_install -U pytest To check your installation has installed the correct version:: $ py.test --version This is pytest version 2.8.7, imported from $PYTHON_PREFIX/lib/python3.4/site-packages/pytest.py If you get an error checkout :ref:`installation issues`. .. _`simpletest`: Our first test run ---------------------------------------------------------- Let's create a first test file with a simple test function:: # content of test_sample.py def func(x): return x + 1 def test_answer(): assert func(3) == 5 That's it.

More generally, it follows :ref:`standard test discovery rules `. Asserting that a certain exception is raised -------------------------------------------------------------- If you want to assert that some code raises an exception you can use the ``raises`` helper:: # content of test_sysexit.py import pytest def f(): raise SystemExit(1) def test_mytest(): with pytest.raises(SystemExit): f() Running it with, this time in "quiet" reporting mode:: $ py.test -q test_sysexit.py . 1 passed in 0.12 seconds Grouping multiple tests in a class -------------------------------------------------------------- Once you start to have more than a few tests it often makes sense to group tests logically, in classes and modules. Let's write a class containing two tests:: # content of test_class.py class TestClass: def test_one(self): x = "this" assert 'h' in x def test_two(self): x = "hello" assert hasattr(x, 'check') The two tests are found because of the standard :ref:`test discovery`. There is no need to subclass anything. We can simply run the module by passing its filename:: $ py.test -q test_class.py .F ======= FAILURES ======== _______ TestClass.test_two ________ self = def test_two(self): x = "hello" > assert hasattr(x, 'check') E assert hasattr('hello', 'check') test_class.py:8: AssertionError 1 failed, 1 passed in 0.12 seconds The first test passed, the second failed. Again we can easily see the intermediate values used in the assertion, helping us to understand the reason for the failure. Going functional: requesting a unique temporary directory -------------------------------------------------------------- For functional tests one often needs to create some files and pass them to application objects. pytest provides :ref:`builtinfixtures` which allow to request arbitrary resources, for example a unique temporary directory:: # content of test_tmpdir.py def test_needsfiles(tmpdir): print (tmpdir) assert 0 We list the name ``tmpdir`` in the test function signature and ``pytest`` will lookup and call a fixture factory to create the resource before performing the test function call. Let's just run it:: $ py.test -q test_tmpdir.py F ======= FAILURES ======== _______ test_needsfiles ________ tmpdir = local('PYTEST_TMPDIR/test_needsfiles0') def test_needsfiles(tmpdir): print (tmpdir) > assert 0 E assert 0 test_tmpdir.py:3: AssertionError --------------------------- Captured stdout call --------------------------- PYTEST_TMPDIR/test_needsfiles0 1 failed in 0.12 seconds Before the test runs, a unique-per-test-invocation temporary directory was created.

If a factory wants to re-use a resource across different scopes, it often used the ``request.cached_setup()`` helper to manage caching of resources. Here is a basic example how we could implement a per-session Database object:: # content of conftest.py class Database: def __init__(self): print ("database instance created") def destroy(self): print ("database instance destroyed") def pytest_funcarg__db(request): return request.cached_setup(setup=DataBase, teardown=lambda db: db.destroy, scope="session") There are several limitations and difficulties with this approach: 1. Scoping funcarg resource creation is not straight forward, instead one must understand the intricate cached_setup() method mechanics. 2. parametrizing the "db" resource is not straight forward: you need to apply a "parametrize" decorator or implement a :py:func:`~hookspec.pytest_generate_tests` hook calling :py:func:`~python.Metafunc.parametrize` which performs parametrization at the places where the resource is used. Moreover, you need to modify the factory to use an ``extrakey`` parameter containing ``request.param`` to the :py:func:`~python.Request.cached_setup` call. 3. Multiple parametrized session-scoped resources will be active at the same time, making it hard for them to affect global state of the application under test. 4. there is no way how you can make use of funcarg factories in xUnit setup methods. 5. A non-parametrized fixture function cannot use a parametrized funcarg resource if it isn't stated in the test function signature. All of these limitations are addressed with pytest-2.3 and its improved :ref:`fixture mechanism `. Direct scoping of fixture/funcarg factories -------------------------------------------------------- Instead of calling cached_setup() with a cache scope, you can use the :ref:`@pytest.fixture ` decorator and directly state the scope:: @pytest.fixture(scope="session") def db(request): # factory will only be invoked once per session - db = DataBase() request.addfinalizer(db.destroy) # destroy when session is finished return db This factory implementation does not need to call ``cached_setup()`` anymore because it will only be invoked once per session. Moreover, the ``request.addfinalizer()`` registers a finalizer according to the specified resource scope on which the factory function is operating. Direct parametrization of funcarg resource factories ---------------------------------------------------------- Previously, funcarg factories could not directly cause parametrization. You needed to specify a ``@parametrize`` decorator on your test function or implement a ``pytest_generate_tests`` hook to perform parametrization, i.e. calling a test multiple times with different value sets. pytest-2.3 introduces a decorator for use on the factory itself:: @pytest.fixture(params=["mysql", "pg"]) def db(request): ... # use request.param Here the factory will be invoked twice (with the respective "mysql" and "pg" values set as ``request.param`` attributes) and and all of the tests requiring "db" will run twice as well. The "mysql" and "pg" values will also be used for reporting the test-invocation variants. This new way of parametrizing funcarg factories should in many cases allow to re-use already written factories because effectively ``request.param`` was already used when test functions/classes were parametrized via :py:func:`~_pytest.python.Metafunc.parametrize(indirect=True)` calls. Of course it's perfectly fine to combine parametrization and scoping:: @pytest.fixture(scope="session", params=["mysql", "pg"]) def db(request): if request.param == "mysql": db = MySQL() elif request.param == "pg": db = PG() request.addfinalizer(db.destroy) # destroy when session is finished return db This would execute all tests requiring the per-session "db" resource twice, receiving the values created by the two respective invocations to the factory function. No ``pytest_funcarg__`` prefix when using @fixture decorator ------------------------------------------------------------------- When using the ``@fixture`` decorator the name of the function denotes the name under which the resource can be accessed as a function argument:: @pytest.fixture() def db(request): ... The name under which the funcarg resource can be requested is ``db``. You can still use the "old" non-decorator way of specifying funcarg factories aka:: def pytest_funcarg__db(request): ... But it is then not possible to define scoping and parametrization. It is thus recommended to use the factory decorator. solving per-session setup / autouse fixtures -------------------------------------------------------------- pytest for a long time offered a pytest_configure and a pytest_sessionstart hook which are often used to setup global resources. This suffers from several problems: 1. in distributed testing the master process would setup test resources that are never needed because it only co-ordinates the test run activities of the slave processes. 2. if you only perform a collection (with "--collect-only") resource-setup will still be executed. 3. If a pytest_sessionstart is contained in some subdirectories conftest.py file, it will not be called. This stems from the fact that this hook is actually used for reporting, in particular the test-header with platform/custom information. Moreover, it was not easy to define a scoped setup from plugins or conftest files other than to implement a ``pytest_runtest_setup()`` hook and caring for scoping/caching yourself. And it's virtually impossible to do this with parametrization as ``pytest_runtest_setup()`` is called during test execution and parametrization happens at collection time. It follows that pytest_configure/session/runtest_setup are often not appropriate for implementing common fixture needs. Therefore, pytest-2.3 introduces :ref:`autouse fixtures` which fully integrate with the generic :ref:`fixture mechanism ` and obsolete many prior uses of pytest hooks. funcargs/fixture discovery now happens at collection time --------------------------------------------------------------------- pytest-2.3 takes care to discover fixture/funcarg factories at collection time. This is more efficient especially for large test suites. Moreover, a call to "py.test --collect-only" should be able to in the future show a lot of setup-information and thus presents a nice method to get an overview of fixture management in your project. .. _`compatibility notes`: .. _`funcargscompat`: Conclusion and compatibility notes --------------------------------------------------------- **funcargs** were originally introduced to pytest-2.0. In pytest-2.3 the mechanism was extended and refined and is now described as fixtures: * previously funcarg factories were specified with a special ``pytest_funcarg__NAME`` prefix instead of using the ``@pytest.fixture`` decorator. * Factories received a ``request`` object which managed caching through ``request.cached_setup()`` calls and allowed using other funcargs via ``request.getfuncargvalue()`` calls. These intricate APIs made it hard to do proper parametrization and implement resource caching. The new :py:func:`pytest.fixture` decorator allows to declare the scope and let pytest figure things out for you. * if you used parametrization and funcarg factories which made use of ``request.cached_setup()`` it is recommended to invest a few minutes and simplify your fixture function code to use the :ref:`@pytest.fixture` decorator instead. This will also allow to take advantage of the automatic per-resource grouping of tests. pytest-2.8.7/doc/en/fixture.rst0000664000175000017500000010053712651247335017023 0ustar ronnyronny00000000000000.. _fixture: .. _fixtures: .. _`fixture functions`: pytest fixtures: explicit, modular, scalable ======================================================== .. currentmodule:: _pytest.python .. versionadded:: 2.0/2.3/2.4 .. _`xUnit`: http://en.wikipedia.org/wiki/XUnit .. _`purpose of test fixtures`: http://en.wikipedia.org/wiki/Test_fixture#Software .. _`Dependency injection`: http://en.wikipedia.org/wiki/Dependency_injection#Definition The `purpose of test fixtures`_ is to provide a fixed baseline upon which tests can reliably and repeatedly execute. pytest fixtures offer dramatic improvements over the classic xUnit style of setup/teardown functions: * fixtures have explicit names and are activated by declaring their use from test functions, modules, classes or whole projects. * fixtures are implemented in a modular manner, as each fixture name triggers a *fixture function* which can itself use other fixtures. * fixture management scales from simple unit to complex functional testing, allowing to parametrize fixtures and tests according to configuration and component options, or to re-use fixtures across class, module or whole test session scopes. In addition, pytest continues to support :ref:`xunitsetup`. You can mix both styles, moving incrementally from classic to new style, as you prefer. You can also start out from existing :ref:`unittest.TestCase style ` or :ref:`nose based ` projects. .. note:: pytest-2.4 introduced an additional experimental :ref:`yield fixture mechanism ` for easier context manager integration and more linear writing of teardown code. .. _`funcargs`: .. _`funcarg mechanism`: .. _`fixture function`: .. _`@pytest.fixture`: .. _`pytest.fixture`: Fixtures as Function arguments ----------------------------------------- Test functions can receive fixture objects by naming them as an input argument. For each argument name, a fixture function with that name provides the fixture object. Fixture functions are registered by marking them with :py:func:`@pytest.fixture <_pytest.python.fixture>`. Let's look at a simple self-contained test module containing a fixture and a test function using it:: # content of ./test_smtpsimple.py import pytest @pytest.fixture def smtp(): import smtplib return smtplib.SMTP("smtp.gmail.com") def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 assert 0 # for demo purposes Here, the ``test_ehlo`` needs the ``smtp`` fixture value. pytest will discover and call the :py:func:`@pytest.fixture <_pytest.python.fixture>` marked ``smtp`` fixture function. Running the test looks like this:: $ py.test test_smtpsimple.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_smtpsimple.py F ======= FAILURES ======== _______ test_ehlo ________ smtp = def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 > assert 0 # for demo purposes E assert 0 test_smtpsimple.py:11: AssertionError ======= 1 failed in 0.12 seconds ======== In the failure traceback we see that the test function was called with a ``smtp`` argument, the ``smtplib.SMTP()`` instance created by the fixture function. The test function fails on our deliberate ``assert 0``. Here is the exact protocol used by ``pytest`` to call the test function this way: 1. pytest :ref:`finds ` the ``test_ehlo`` because of the ``test_`` prefix. The test function needs a function argument named ``smtp``. A matching fixture function is discovered by looking for a fixture-marked function named ``smtp``. 2. ``smtp()`` is called to create an instance. 3. ``test_ehlo()`` is called and fails in the last line of the test function. Note that if you misspell a function argument or want to use one that isn't available, you'll see an error with a list of available function arguments. .. Note:: You can always issue:: py.test --fixtures test_simplefactory.py to see available fixtures. In versions prior to 2.3 there was no ``@pytest.fixture`` marker and you had to use a magic ``pytest_funcarg__NAME`` prefix for the fixture factory. This remains and will remain supported but is not anymore advertised as the primary means of declaring fixture functions. "Funcargs" a prime example of dependency injection --------------------------------------------------- When injecting fixtures to test functions, pytest-2.0 introduced the term "funcargs" or "funcarg mechanism" which continues to be present also in docs today. It now refers to the specific case of injecting fixture values as arguments to test functions. With pytest-2.3 there are more possibilities to use fixtures but "funcargs" remain as the main way as they allow to directly state the dependencies of a test function. As the following examples show in more detail, funcargs allow test functions to easily receive and work against specific pre-initialized application objects without having to care about import/setup/cleanup details. It's a prime example of `dependency injection`_ where fixture functions take the role of the *injector* and test functions are the *consumers* of fixture objects. .. _smtpshared: Sharing a fixture across tests in a module (or class/session) ----------------------------------------------------------------- .. regendoc:wipe Fixtures requiring network access depend on connectivity and are usually time-expensive to create. Extending the previous example, we can add a ``scope='module'`` parameter to the :py:func:`@pytest.fixture <_pytest.python.fixture>` invocation to cause the decorated ``smtp`` fixture function to only be invoked once per test module. Multiple test functions in a test module will thus each receive the same ``smtp`` fixture instance. The next example puts the fixture function into a separate ``conftest.py`` file so that tests from multiple test modules in the directory can access the fixture function:: # content of conftest.py import pytest import smtplib @pytest.fixture(scope="module") def smtp(): return smtplib.SMTP("smtp.gmail.com") The name of the fixture again is ``smtp`` and you can access its result by listing the name ``smtp`` as an input parameter in any test or fixture function (in or below the directory where ``conftest.py`` is located):: # content of test_module.py def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 assert b"smtp.gmail.com" in msg assert 0 # for demo purposes def test_noop(smtp): response, msg = smtp.noop() assert response == 250 assert 0 # for demo purposes We deliberately insert failing ``assert 0`` statements in order to inspect what is going on and can now run the tests:: $ py.test test_module.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py FF ======= FAILURES ======== _______ test_ehlo ________ smtp = def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 assert b"smtp.gmail.com" in msg > assert 0 # for demo purposes E assert 0 test_module.py:6: AssertionError _______ test_noop ________ smtp = def test_noop(smtp): response, msg = smtp.noop() assert response == 250 > assert 0 # for demo purposes E assert 0 test_module.py:11: AssertionError ======= 2 failed in 0.12 seconds ======== You see the two ``assert 0`` failing and more importantly you can also see that the same (module-scoped) ``smtp`` object was passed into the two test functions because pytest shows the incoming argument values in the traceback. As a result, the two test functions using ``smtp`` run as quick as a single one because they reuse the same instance. If you decide that you rather want to have a session-scoped ``smtp`` instance, you can simply declare it: .. code-block:: python @pytest.fixture(scope="session") def smtp(...): # the returned fixture value will be shared for # all tests needing it .. _`finalization`: Fixture finalization / executing teardown code ------------------------------------------------------------- pytest supports execution of fixture specific finalization code when the fixture goes out of scope. By accepting a ``request`` object into your fixture function you can call its ``request.addfinalizer`` one or multiple times:: # content of conftest.py import smtplib import pytest @pytest.fixture(scope="module") def smtp(request): smtp = smtplib.SMTP("smtp.gmail.com") def fin(): print ("teardown smtp") smtp.close() request.addfinalizer(fin) return smtp # provide the fixture value The ``fin`` function will execute when the last test using the fixture in the module has finished execution. Let's execute it:: $ py.test -s -q --tb=no FFteardown smtp 2 failed in 0.12 seconds We see that the ``smtp`` instance is finalized after the two tests finished execution. Note that if we decorated our fixture function with ``scope='function'`` then fixture setup and cleanup would occur around each single test. In either case the test module itself does not need to change or know about these details of fixture setup. .. _`request-context`: Fixtures can introspect the requesting test context ------------------------------------------------------------- Fixture function can accept the :py:class:`request ` object to introspect the "requesting" test function, class or module context. Further extending the previous ``smtp`` fixture example, let's read an optional server URL from the test module which uses our fixture:: # content of conftest.py import pytest import smtplib @pytest.fixture(scope="module") def smtp(request): server = getattr(request.module, "smtpserver", "smtp.gmail.com") smtp = smtplib.SMTP(server) def fin(): print ("finalizing %s (%s)" % (smtp, server)) smtp.close() request.addfinalizer(fin) return smtp We use the ``request.module`` attribute to optionally obtain an ``smtpserver`` attribute from the test module. If we just execute again, nothing much has changed:: $ py.test -s -q --tb=no FFfinalizing (smtp.gmail.com) 2 failed in 0.12 seconds Let's quickly create another test module that actually sets the server URL in its module namespace:: # content of test_anothersmtp.py smtpserver = "mail.python.org" # will be read by smtp fixture def test_showhelo(smtp): assert 0, smtp.helo() Running it:: $ py.test -qq --tb=short test_anothersmtp.py F ======= FAILURES ======== _______ test_showhelo ________ test_anothersmtp.py:5: in test_showhelo assert 0, smtp.helo() E AssertionError: (250, b'mail.python.org') E assert 0 voila! The ``smtp`` fixture function picked up our mail server name from the module namespace. .. _`fixture-parametrize`: Parametrizing a fixture ----------------------------------------------------------------- Fixture functions can be parametrized in which case they will be called multiple times, each time executing the set of dependent tests, i. e. the tests that depend on this fixture. Test functions do usually not need to be aware of their re-running. Fixture parametrization helps to write exhaustive functional tests for components which themselves can be configured in multiple ways. Extending the previous example, we can flag the fixture to create two ``smtp`` fixture instances which will cause all tests using the fixture to run twice. The fixture function gets access to each parameter through the special :py:class:`request ` object:: # content of conftest.py import pytest import smtplib @pytest.fixture(scope="module", params=["smtp.gmail.com", "mail.python.org"]) def smtp(request): smtp = smtplib.SMTP(request.param) def fin(): print ("finalizing %s" % smtp) smtp.close() request.addfinalizer(fin) return smtp The main change is the declaration of ``params`` with :py:func:`@pytest.fixture <_pytest.python.fixture>`, a list of values for each of which the fixture function will execute and can access a value via ``request.param``. No test function code needs to change. So let's just do another run:: $ py.test -q test_module.py FFFF ======= FAILURES ======== _______ test_ehlo[smtp.gmail.com] ________ smtp = def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 assert b"smtp.gmail.com" in msg > assert 0 # for demo purposes E assert 0 test_module.py:6: AssertionError _______ test_noop[smtp.gmail.com] ________ smtp = def test_noop(smtp): response, msg = smtp.noop() assert response == 250 > assert 0 # for demo purposes E assert 0 test_module.py:11: AssertionError _______ test_ehlo[mail.python.org] ________ smtp = def test_ehlo(smtp): response, msg = smtp.ehlo() assert response == 250 > assert b"smtp.gmail.com" in msg E assert b'smtp.gmail.com' in b'mail.python.org\nSIZE 51200000\nETRN\nSTARTTLS\nENHANCEDSTATUSCODES\n8BITMIME\nDSN\nSMTPUTF8' test_module.py:5: AssertionError -------------------------- Captured stdout setup --------------------------- finalizing _______ test_noop[mail.python.org] ________ smtp = def test_noop(smtp): response, msg = smtp.noop() assert response == 250 > assert 0 # for demo purposes E assert 0 test_module.py:11: AssertionError 4 failed in 0.12 seconds We see that our two test functions each ran twice, against the different ``smtp`` instances. Note also, that with the ``mail.python.org`` connection the second test fails in ``test_ehlo`` because a different server string is expected than what arrived. pytest will build a string that is the test ID for each fixture value in a parametrized fixture, e.g. ``test_ehlo[smtp.gmail.com]`` and ``test_ehlo[mail.python.org]`` in the above examples. These IDs can be used with ``-k`` to select specific cases to run, and they will also identify the specific case when one is failing. Running pytest with ``--collect-only`` will show the generated IDs. Numbers, strings, booleans and None will have their usual string representation used in the test ID. For other objects, pytest will make a string based on the argument name. It is possible to customise the string used in a test ID for a certain fixture value by using the ``ids`` keyword argument:: # content of test_ids.py import pytest @pytest.fixture(params=[0, 1], ids=["spam", "ham"]) def a(request): return request.param def test_a(a): pass def idfn(fixture_value): if fixture_value == 0: return "eggs" else: return None @pytest.fixture(params=[0, 1], ids=idfn) def b(request): return request.param def test_b(b): pass The above shows how ``ids`` can be either a list of strings to use or a function which will be called with the fixture value and then has to return a string to use. In the latter case if the function return ``None`` then pytest's auto-generated ID will be used. Running the above tests results in the following test IDs being used:: $ py.test --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 10 items ======= no tests ran in 0.12 seconds ======== .. _`interdependent fixtures`: Modularity: using fixtures from a fixture function ---------------------------------------------------------- You can not only use fixtures in test functions but fixture functions can use other fixtures themselves. This contributes to a modular design of your fixtures and allows re-use of framework-specific fixtures across many projects. As a simple example, we can extend the previous example and instantiate an object ``app`` where we stick the already defined ``smtp`` resource into it:: # content of test_appsetup.py import pytest class App: def __init__(self, smtp): self.smtp = smtp @pytest.fixture(scope="module") def app(smtp): return App(smtp) def test_smtp_exists(app): assert app.smtp Here we declare an ``app`` fixture which receives the previously defined ``smtp`` fixture and instantiates an ``App`` object with it. Let's run it:: $ py.test -v test_appsetup.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 2 items test_appsetup.py::test_smtp_exists[smtp.gmail.com] PASSED test_appsetup.py::test_smtp_exists[mail.python.org] PASSED ======= 2 passed in 0.12 seconds ======== Due to the parametrization of ``smtp`` the test will run twice with two different ``App`` instances and respective smtp servers. There is no need for the ``app`` fixture to be aware of the ``smtp`` parametrization as pytest will fully analyse the fixture dependency graph. Note, that the ``app`` fixture has a scope of ``module`` and uses a module-scoped ``smtp`` fixture. The example would still work if ``smtp`` was cached on a ``session`` scope: it is fine for fixtures to use "broader" scoped fixtures but not the other way round: A session-scoped fixture could not use a module-scoped one in a meaningful way. .. _`automatic per-resource grouping`: Automatic grouping of tests by fixture instances ---------------------------------------------------------- .. regendoc: wipe pytest minimizes the number of active fixtures during test runs. If you have a parametrized fixture, then all the tests using it will first execute with one instance and then finalizers are called before the next fixture instance is created. Among other things, this eases testing of applications which create and use global state. The following example uses two parametrized funcargs, one of which is scoped on a per-module basis, and all the functions perform ``print`` calls to show the setup/teardown flow:: # content of test_module.py import pytest @pytest.fixture(scope="module", params=["mod1", "mod2"]) def modarg(request): param = request.param print ("create", param) def fin(): print ("fin %s" % param) return param @pytest.fixture(scope="function", params=[1,2]) def otherarg(request): return request.param def test_0(otherarg): print (" test0", otherarg) def test_1(modarg): print (" test1", modarg) def test_2(otherarg, modarg): print (" test2", otherarg, modarg) Let's run the tests in verbose mode and with looking at the print-output:: $ py.test -v -s test_module.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 8 items test_module.py::test_0[1] test0 1 PASSED test_module.py::test_0[2] test0 2 PASSED test_module.py::test_1[mod1] create mod1 test1 mod1 PASSED test_module.py::test_2[1-mod1] test2 1 mod1 PASSED test_module.py::test_2[2-mod1] test2 2 mod1 PASSED test_module.py::test_1[mod2] create mod2 test1 mod2 PASSED test_module.py::test_2[1-mod2] test2 1 mod2 PASSED test_module.py::test_2[2-mod2] test2 2 mod2 PASSED ======= 8 passed in 0.12 seconds ======== You can see that the parametrized module-scoped ``modarg`` resource caused an ordering of test execution that lead to the fewest possible "active" resources. The finalizer for the ``mod1`` parametrized resource was executed before the ``mod2`` resource was setup. .. _`usefixtures`: Using fixtures from classes, modules or projects ---------------------------------------------------------------------- .. regendoc:wipe Sometimes test functions do not directly need access to a fixture object. For example, tests may require to operate with an empty directory as the current working directory but otherwise do not care for the concrete directory. Here is how you can can use the standard `tempfile `_ and pytest fixtures to achieve it. We separate the creation of the fixture into a conftest.py file:: # content of conftest.py import pytest import tempfile import os @pytest.fixture() def cleandir(): newpath = tempfile.mkdtemp() os.chdir(newpath) and declare its use in a test module via a ``usefixtures`` marker:: # content of test_setenv.py import os import pytest @pytest.mark.usefixtures("cleandir") class TestDirectoryInit: def test_cwd_starts_empty(self): assert os.listdir(os.getcwd()) == [] with open("myfile", "w") as f: f.write("hello") def test_cwd_again_starts_empty(self): assert os.listdir(os.getcwd()) == [] Due to the ``usefixtures`` marker, the ``cleandir`` fixture will be required for the execution of each test method, just as if you specified a "cleandir" function argument to each of them. Let's run it to verify our fixture is activated and the tests pass:: $ py.test -q .. 2 passed in 0.12 seconds You can specify multiple fixtures like this: .. code-block:: python @pytest.mark.usefixtures("cleandir", "anotherfixture") and you may specify fixture usage at the test module level, using a generic feature of the mark mechanism: .. code-block:: python pytestmark = pytest.mark.usefixtures("cleandir") Note that the assigned variable *must* be called ``pytestmark``, assigning e.g. ``foomark`` will not activate the fixtures. Lastly you can put fixtures required by all tests in your project into an ini-file: .. code-block:: ini # content of pytest.ini [pytest] usefixtures = cleandir .. _`autouse`: .. _`autouse fixtures`: Autouse fixtures (xUnit setup on steroids) ---------------------------------------------------------------------- .. regendoc:wipe Occasionally, you may want to have fixtures get invoked automatically without a `usefixtures`_ or `funcargs`_ reference. As a practical example, suppose we have a database fixture which has a begin/rollback/commit architecture and we want to automatically surround each test method by a transaction and a rollback. Here is a dummy self-contained implementation of this idea:: # content of test_db_transact.py import pytest class DB: def __init__(self): self.intransaction = [] def begin(self, name): self.intransaction.append(name) def rollback(self): self.intransaction.pop() @pytest.fixture(scope="module") def db(): return DB() class TestClass: @pytest.fixture(autouse=True) def transact(self, request, db): db.begin(request.function.__name__) request.addfinalizer(db.rollback) def test_method1(self, db): assert db.intransaction == ["test_method1"] def test_method2(self, db): assert db.intransaction == ["test_method2"] The class-level ``transact`` fixture is marked with *autouse=true* which implies that all test methods in the class will use this fixture without a need to state it in the test function signature or with a class-level ``usefixtures`` decorator. If we run it, we get two passing tests:: $ py.test -q .. 2 passed in 0.12 seconds Here is how autouse fixtures work in other scopes: - if an autouse fixture is defined in a test module, all its test functions automatically use it. - if an autouse fixture is defined in a conftest.py file then all tests in all test modules below its directory will invoke the fixture. - lastly, and **please use that with care**: if you define an autouse fixture in a plugin, it will be invoked for all tests in all projects where the plugin is installed. This can be useful if a fixture only anyway works in the presence of certain settings e. g. in the ini-file. Such a global fixture should always quickly determine if it should do any work and avoid otherwise expensive imports or computation. Note that the above ``transact`` fixture may very well be a fixture that you want to make available in your project without having it generally active. The canonical way to do that is to put the transact definition into a conftest.py file **without** using ``autouse``:: # content of conftest.py @pytest.fixture() def transact(self, request, db): db.begin() request.addfinalizer(db.rollback) and then e.g. have a TestClass using it by declaring the need:: @pytest.mark.usefixtures("transact") class TestClass: def test_method1(self): ... All test methods in this TestClass will use the transaction fixture while other test classes or functions in the module will not use it unless they also add a ``transact`` reference. Shifting (visibility of) fixture functions ---------------------------------------------------- If during implementing your tests you realize that you want to use a fixture function from multiple test files you can move it to a :ref:`conftest.py ` file or even separately installable :ref:`plugins ` without changing test code. The discovery of fixtures functions starts at test classes, then test modules, then ``conftest.py`` files and finally builtin and third party plugins. Overriding fixtures on various levels ------------------------------------- In relatively large test suite, you most likely need to ``override`` a ``global`` or ``root`` fixture with a ``locally`` defined one, keeping the test code readable and maintainable. Override a fixture on a folder (conftest) level ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Given the tests file structure is: :: tests/ __init__.py conftest.py # content of tests/conftest.py import pytest @pytest.fixture def username(): return 'username' test_something.py # content of tests/test_something.py def test_username(username): assert username == 'username' subfolder/ __init__.py conftest.py # content of tests/subfolder/conftest.py import pytest @pytest.fixture def username(username): return 'overridden-' + username test_something.py # content of tests/subfolder/test_something.py def test_username(username): assert username == 'overridden-username' As you can see, a fixture with the same name can be overridden for certain test folder level. Note that the ``base`` or ``super`` fixture can be accessed from the ``overriding`` fixture easily - used in the example above. Override a fixture on a test module level ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Given the tests file structure is: :: tests/ __init__.py conftest.py # content of tests/conftest.py @pytest.fixture def username(): return 'username' test_something.py # content of tests/test_something.py import pytest @pytest.fixture def username(username): return 'overridden-' + username def test_username(username): assert username == 'overridden-username' test_something_else.py # content of tests/test_something_else.py import pytest @pytest.fixture def username(username): return 'overridden-else-' + username def test_username(username): assert username == 'overridden-else-username' In the example above, a fixture with the same name can be overridden for certain test module. Override a fixture with direct test parametrization ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Given the tests file structure is: :: tests/ __init__.py conftest.py # content of tests/conftest.py import pytest @pytest.fixture def username(): return 'username' @pytest.fixture def other_username(username): return 'other-' + username test_something.py # content of tests/test_something.py import pytest @pytest.mark.parametrize('username', ['directly-overridden-username']) def test_username(username): assert username == 'directly-overridden-username' @pytest.mark.parametrize('username', ['directly-overridden-username-other']) def test_username_other(other_username): assert username == 'other-directly-overridden-username-other' In the example above, a fixture value is overridden by the test parameter value. Note that the value of the fixture can be overridden this way even if the test doesn't use it directly (doesn't mention it in the function prototype). Override a parametrized fixture with non-parametrized one and vice versa ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Given the tests file structure is: :: tests/ __init__.py conftest.py # content of tests/conftest.py import pytest @pytest.fixture(params=['one', 'two', 'three']) def parametrized_username(request): return request.param @pytest.fixture def non_parametrized_username(request): return 'username' test_something.py # content of tests/test_something.py import pytest @pytest.fixture def parametrized_username(): return 'overridden-username' @pytest.fixture(params=['one', 'two', 'three']) def non_parametrized_username(request): return request.param def test_username(parametrized_username): assert parametrized_username == 'overridden-username' def test_parametrized_username(non_parametrized_username): assert non_parametrized_username in ['one', 'two', 'three'] test_something_else.py # content of tests/test_something_else.py def test_username(parametrized_username): assert parametrized_username in ['one', 'two', 'three'] def test_username(non_parametrized_username): assert non_parametrized_username == 'username' In the example above, a parametrized fixture is overridden with a non-parametrized version, and a non-parametrized fixture is overridden with a parametrized version for certain test module. The same applies for the test folder level obviously. pytest-2.8.7/doc/en/feedback.rst0000664000175000017500000000031512651247335017052 0ustar ronnyronny00000000000000 What users say: `py.test is pretty much the best thing ever`_ (Alex Gaynor) .. _`py.test is pretty much the best thing ever`_ (Alex Gaynor) http://twitter.com/#!/alex_gaynor/status/22389410366 pytest-2.8.7/doc/en/faq.rst0000664000175000017500000001627312651247335016107 0ustar ronnyronny00000000000000Some Issues and Questions ================================== .. note:: This FAQ is here only mostly for historic reasons. Checkout `pytest Q&A at Stackoverflow `_ for many questions and answers related to pytest and/or use :ref:`contact channels` to get help. On naming, nosetests, licensing and magic ------------------------------------------------ How does pytest relate to nose and unittest? +++++++++++++++++++++++++++++++++++++++++++++++++ ``pytest`` and nose_ share basic philosophy when it comes to running and writing Python tests. In fact, you can run many tests written for nose with ``pytest``. nose_ was originally created as a clone of ``pytest`` when ``pytest`` was in the ``0.8`` release cycle. Note that starting with pytest-2.0 support for running unittest test suites is majorly improved. how does pytest relate to twisted's trial? ++++++++++++++++++++++++++++++++++++++++++++++ Since some time ``pytest`` has builtin support for supporting tests written using trial. It does not itself start a reactor, however, and does not handle Deferreds returned from a test in pytest style. If you are using trial's unittest.TestCase chances are that you can just run your tests even if you return Deferreds. In addition, there also is a dedicated `pytest-twisted `_ plugin which allows you to return deferreds from pytest-style tests, allowing the use of :ref:`fixtures` and other features. how does pytest work with Django? ++++++++++++++++++++++++++++++++++++++++++++++ In 2012, some work is going into the `pytest-django plugin `_. It substitutes the usage of Django's ``manage.py test`` and allows the use of all pytest features_ most of which are not available from Django directly. .. _features: features.html What's this "magic" with pytest? (historic notes) ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Around 2007 (version ``0.8``) some people thought that ``pytest`` was using too much "magic". It had been part of the `pylib`_ which contains a lot of unrelated python library code. Around 2010 there was a major cleanup refactoring, which removed unused or deprecated code and resulted in the new ``pytest`` PyPI package which strictly contains only test-related code. This release also brought a complete pluginification such that the core is around 300 lines of code and everything else is implemented in plugins. Thus ``pytest`` today is a small, universally runnable and customizable testing framework for Python. Note, however, that ``pytest`` uses metaprogramming techniques and reading its source is thus likely not something for Python beginners. A second "magic" issue was the assert statement debugging feature. Nowadays, ``pytest`` explicitly rewrites assert statements in test modules in order to provide more useful :ref:`assert feedback `. This completely avoids previous issues of confusing assertion-reporting. It also means, that you can use Python's ``-O`` optimization without losing assertions in test modules. ``pytest`` contains a second, mostly obsolete, assert debugging technique, invoked via ``--assert=reinterpret``, activated by default on Python-2.5: When an ``assert`` statement fails, ``pytest`` re-interprets the expression part to show intermediate values. This technique suffers from a caveat that the rewriting does not: If your expression has side effects (better to avoid them anyway!) the intermediate values may not be the same, confusing the reinterpreter and obfuscating the initial error (this is also explained at the command line if it happens). You can also turn off all assertion interaction using the ``--assert=plain`` option. .. _`py namespaces`: index.html .. _`py/__init__.py`: http://bitbucket.org/hpk42/py-trunk/src/trunk/py/__init__.py Why a ``py.test`` instead of a ``pytest`` command? ++++++++++++++++++++++++++++++++++++++++++++++++++ Some of the reasons are historic, others are practical. ``pytest`` used to be part of the ``py`` package which provided several developer utilities, all starting with ``py.``, thus providing nice TAB-completion. If you install ``pip install pycmd`` you get these tools from a separate package. These days the command line tool could be called ``pytest`` but since many people have gotten used to the old name and there is another tool named "pytest" we just decided to stick with ``py.test`` for now. pytest fixtures, parametrized tests ------------------------------------------------------- .. _funcargs: funcargs.html Is using pytest fixtures versus xUnit setup a style question? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ For simple applications and for people experienced with nose_ or unittest-style test setup using `xUnit style setup`_ probably feels natural. For larger test suites, parametrized testing or setup of complex test resources using fixtures_ may feel more natural. Moreover, fixtures are ideal for writing advanced test support code (like e.g. the monkeypatch_, the tmpdir_ or capture_ fixtures) because the support code can register setup/teardown functions in a managed class/module/function scope. .. _monkeypatch: monkeypatch.html .. _tmpdir: tmpdir.html .. _capture: capture.html .. _fixtures: fixture.html .. _`why pytest_pyfuncarg__ methods?`: .. _`Convention over Configuration`: http://en.wikipedia.org/wiki/Convention_over_Configuration Can I yield multiple values from a fixture function? ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ There are two conceptual reasons why yielding from a factory function is not possible: * If multiple factories yielded values there would be no natural place to determine the combination policy - in real-world examples some combinations often should not run. * Calling factories for obtaining test function arguments is part of setting up and running a test. At that point it is not possible to add new test calls to the test collection anymore. However, with pytest-2.3 you can use the :ref:`@pytest.fixture` decorator and specify ``params`` so that all tests depending on the factory-created resource will run multiple times with different parameters. You can also use the ``pytest_generate_tests`` hook to implement the `parametrization scheme of your choice`_. See also :ref:`paramexamples` for more examples. .. _`parametrization scheme of your choice`: http://tetamap.wordpress.com/2009/05/13/parametrizing-python-tests-generalized/ pytest interaction with other packages --------------------------------------------------- Issues with pytest, multiprocess and setuptools? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ On Windows the multiprocess package will instantiate sub processes by pickling and thus implicitly re-import a lot of local modules. Unfortunately, setuptools-0.6.11 does not ``if __name__=='__main__'`` protect its generated command line script. This leads to infinite recursion when running a test that instantiates Processes. As of mid-2013, there shouldn't be a problem anymore when you use the standard setuptools (note that distribute has been merged back into setuptools which is now shipped directly with virtualenv). .. include:: links.inc pytest-2.8.7/doc/en/doctest.rst0000664000175000017500000000467112651247335017004 0ustar ronnyronny00000000000000 Doctest integration for modules and test files ========================================================= By default all files matching the ``test*.txt`` pattern will be run through the python standard ``doctest`` module. You can change the pattern by issuing:: py.test --doctest-glob='*.rst' on the command line. You can also trigger running of doctests from docstrings in all python modules (including regular python test modules):: py.test --doctest-modules You can make these changes permanent in your project by putting them into a pytest.ini file like this: .. code-block:: ini # content of pytest.ini [pytest] addopts = --doctest-modules If you then have a text file like this:: # content of example.rst hello this is a doctest >>> x = 3 >>> x 3 and another like this:: # content of mymodule.py def something(): """ a doctest in a docstring >>> something() 42 """ return 42 then you can just invoke ``py.test`` without command line options:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: pytest.ini collected 1 items mymodule.py . ======= 1 passed in 0.12 seconds ======== It is possible to use fixtures using the ``getfixture`` helper:: # content of example.rst >>> tmp = getfixture('tmpdir') >>> ... >>> Also, :ref:`usefixtures` and :ref:`autouse` fixtures are supported when executing text doctest files. The standard ``doctest`` module provides some setting flags to configure the strictness of doctest tests. In py.test You can enable those flags those flags using the configuration file. To make pytest ignore trailing whitespaces and ignore lengthy exception stack traces you can just write:: # content of pytest.ini [pytest] doctest_optionflags= NORMALIZE_WHITESPACE IGNORE_EXCEPTION_DETAIL py.test also introduces a new ``ALLOW_UNICODE`` option flag: when enabled, the ``u`` prefix is stripped from unicode strings in expected doctest output. This allows doctests which use unicode to run in Python 2 and 3 unchanged. As with any other option flag, this flag can be enabled in ``pytest.ini`` using the ``doctest_optionflags`` ini option or by an inline comment in the doc test itself:: # content of example.rst >>> get_unicode_greeting() # doctest: +ALLOW_UNICODE 'Hello' pytest-2.8.7/doc/en/customize.rst0000664000175000017500000001660712651247335017363 0ustar ronnyronny00000000000000Basic test configuration =================================== Command line options and configuration file settings ----------------------------------------------------------------- You can get help on command line options and values in INI-style configurations files by using the general help option:: py.test -h # prints options _and_ config file settings This will display command line and configuration file settings which were registered by installed plugins. .. _rootdir: .. _inifiles: initialization: determining rootdir and inifile ----------------------------------------------- .. versionadded:: 2.7 pytest determines a "rootdir" for each test run which depends on the command line arguments (specified test files, paths) and on the existence of inifiles. The determined rootdir and ini-file are printed as part of the pytest header. The rootdir is used for constructing "nodeids" during collection and may also be used by plugins to store project/testrun-specific information. Here is the algorithm which finds the rootdir from ``args``: - determine the common ancestor directory for the specified ``args``. - look for ``pytest.ini``, ``tox.ini`` and ``setup.cfg`` files in the ancestor directory and upwards. If one is matched, it becomes the ini-file and its directory becomes the rootdir. An existing ``pytest.ini`` file will always be considered a match whereas ``tox.ini`` and ``setup.cfg`` will only match if they contain a ``[pytest]`` section. - if no ini-file was found, look for ``setup.py`` upwards from the common ancestor directory to determine the ``rootdir``. - if no ini-file and no ``setup.py`` was found, use the already determined common ancestor as root directory. This allows to work with pytest in structures that are not part of a package and don't have any particular ini-file configuration. Note that options from multiple ini-files candidates are never merged, the first one wins (``pytest.ini`` always wins even if it does not contain a ``[pytest]`` section). The ``config`` object will subsequently carry these attributes: - ``config.rootdir``: the determined root directory, guaranteed to exist. - ``config.inifile``: the determined ini-file, may be ``None``. The rootdir is used a reference directory for constructing test addresses ("nodeids") and can be used also by plugins for storing per-testrun information. Example:: py.test path/to/testdir path/other/ will determine the common ancestor as ``path`` and then check for ini-files as follows:: # first look for pytest.ini files path/pytest.ini path/setup.cfg # must also contain [pytest] section to match path/tox.ini # must also contain [pytest] section to match pytest.ini ... # all the way down to the root # now look for setup.py path/setup.py setup.py ... # all the way down to the root .. _`how to change command line options defaults`: .. _`adding default options`: How to change command line options defaults ------------------------------------------------ It can be tedious to type the same series of command line options every time you use ``pytest``. For example, if you always want to see detailed info on skipped and xfailed tests, as well as have terser "dot" progress output, you can write it into a configuration file: .. code-block:: ini # content of pytest.ini # (or tox.ini or setup.cfg) [pytest] addopts = -rsxX -q Alternatively, you can set a PYTEST_ADDOPTS environment variable to add command line options while the environment is in use:: export PYTEST_ADDOPTS="-rsxX -q" From now on, running ``pytest`` will add the specified options. Builtin configuration file options ---------------------------------------------- .. confval:: minversion Specifies a minimal pytest version required for running tests. minversion = 2.1 # will fail if we run with pytest-2.0 .. confval:: addopts Add the specified ``OPTS`` to the set of command line arguments as if they had been specified by the user. Example: if you have this ini file content: .. code-block:: ini [pytest] addopts = --maxfail=2 -rf # exit after 2 failures, report fail info issuing ``py.test test_hello.py`` actually means:: py.test --maxfail=2 -rf test_hello.py Default is to add no options. .. confval:: norecursedirs Set the directory basename patterns to avoid when recursing for test discovery. The individual (fnmatch-style) patterns are applied to the basename of a directory to decide if to recurse into it. Pattern matching characters:: * matches everything ? matches any single character [seq] matches any character in seq [!seq] matches any char not in seq Default patterns are ``'.*', 'CVS', '_darcs', '{arch}', '*.egg'``. Setting a ``norecursedirs`` replaces the default. Here is an example of how to avoid certain directories: .. code-block:: ini # content of setup.cfg [pytest] norecursedirs = .svn _build tmp* This would tell ``pytest`` to not look into typical subversion or sphinx-build directories or into any ``tmp`` prefixed directory. .. confval:: testpaths .. versionadded:: 2.8 Sets list of directories that should be searched for tests when no specific directories, files or test ids are given in the command line when executing pytest from the :ref:`rootdir ` directory. Useful when all project tests are in a known location to speed up test collection and to avoid picking up undesired tests by accident. .. code-block:: ini # content of pytest.ini [pytest] testpaths = testing doc This tells pytest to only look for tests in ``testing`` and ``doc`` directories when executing from the root directory. .. confval:: python_files One or more Glob-style file patterns determining which python files are considered as test modules. .. confval:: python_classes One or more name prefixes or glob-style patterns determining which classes are considered for test collection. Here is an example of how to collect tests from classes that end in ``Suite``: .. code-block:: ini # content of pytest.ini [pytest] python_classes = *Suite Note that ``unittest.TestCase`` derived classes are always collected regardless of this option, as ``unittest``'s own collection framework is used to collect those tests. .. confval:: python_functions One or more name prefixes or glob-patterns determining which test functions and methods are considered tests. Here is an example of how to collect test functions and methods that end in ``_test``: .. code-block:: ini # content of pytest.ini [pytest] python_functions = *_test Note that this has no effect on methods that live on a ``unittest .TestCase`` derived class, as ``unittest``'s own collection framework is used to collect those tests. See :ref:`change naming conventions` for more detailed examples. .. confval:: doctest_optionflags One or more doctest flag names from the standard ``doctest`` module. :doc:`See how py.test handles doctests `. .. confval:: confcutdir Sets a directory where search upwards for ``conftest.py`` files stops. By default, pytest will stop searching for ``conftest.py`` files upwards from ``pytest.ini``/``tox.ini``/``setup.cfg`` of the project if any, or up to the file-system root. pytest-2.8.7/doc/en/contributing.rst0000664000175000017500000000006712651247335020041 0ustar ronnyronny00000000000000.. _contributing: .. include:: ../../CONTRIBUTING.rst pytest-2.8.7/doc/en/contents.rst0000664000175000017500000000072712651247335017172 0ustar ronnyronny00000000000000.. _toc: Full pytest documentation =========================== `Download latest version as PDF `_ .. `Download latest version as EPUB `_ .. toctree:: :maxdepth: 2 overview apiref example/index plugins cache contributing talks .. only:: html .. toctree:: funcarg_compare announce/index .. only:: html .. toctree:: :hidden: changelog pytest-2.8.7/doc/en/contact.rst0000664000175000017500000000325712651247335016771 0ustar ronnyronny00000000000000 .. _`contact channels`: .. _`contact`: Contact channels =================================== - `pytest issue tracker`_ to report bugs or suggest features (for version 2.0 and above). - `pytest on stackoverflow.com `_ to post questions with the tag ``pytest``.

If a test or a setup method fails its according captured output will usually be shown along with the failure traceback. In addition, ``stdin`` is set to a "null" object which will fail on attempts to read from it because it is rarely desired to wait for interactive input when running automated tests. By default capturing is done by intercepting writes to low level file descriptors. This allows to capture output from simple print statements as well as output from a subprocess started by a test. Setting capturing methods or disabling capturing ------------------------------------------------- There are two ways in which ``pytest`` can perform capturing: * file descriptor (FD) level capturing (default): All writes going to the operating system file descriptors 1 and 2 will be captured. * ``sys`` level capturing: Only writes to Python files ``sys.stdout`` and ``sys.stderr`` will be captured. No capturing of writes to filedescriptors is performed. .. _`disable capturing`: You can influence output capturing mechanisms from the command line:: py.test -s # disable all capturing py.test --capture=sys # replace sys.stdout/stderr with in-mem files py.test --capture=fd # also point filedescriptors 1 and 2 to temp file .. _printdebugging: Using print statements for debugging --------------------------------------------------- One primary benefit of the default capturing of stdout/stderr output is that you can use print statements for debugging:: # content of test_module.py def setup_function(function): print ("setting up %s" % function) def test_func1(): assert True def test_func2(): assert False and running this module will show you precisely the output of the failing function and hide the other one:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py .F ======= FAILURES ======== _______ test_func2 ________ def test_func2(): > assert False E assert False test_module.py:9: AssertionError -------------------------- Captured stdout setup --------------------------- setting up ======= 1 failed, 1 passed in 0.12 seconds ======== Accessing captured output from a test function --------------------------------------------------- The ``capsys`` and ``capfd`` fixtures allow to access stdout/stderr output created during test execution. Here is an example test function that performs some output related checks: .. code-block:: python def test_myoutput(capsys): # or use "capfd" for fd-level print ("hello") sys.stderr.write("world\n") out, err = capsys.readouterr() assert out == "hello\n" assert err == "world\n" print "next" out, err = capsys.readouterr() assert out == "next\n" The ``readouterr()`` call snapshots the output so far - and capturing will be continued. After the test function finishes the original streams will be restored. Using ``capsys`` this way frees your test from having to care about setting/resetting output streams and also interacts well with pytest's own per-test capturing. If you want to capture on filedescriptor level you can use the ``capfd`` function argument which offers the exact same interface but allows to also capture output from libraries or subprocesses that directly write to operating system level output streams (FD1 and FD2). .. include:: links.inc pytest-2.8.7/doc/en/cache.rst0000664000175000017500000001620412651247335016375 0ustar ronnyronny00000000000000Cache: working with cross-testrun state ======================================= .. versionadded:: 2.8 .. warning:: The functionality of this core plugin was previously distributed as a third party plugin named ``pytest-cache``. The core plugin is compatible regarding command line options and API usage except that you can only store/receive data between test runs that is json-serializable. Usage --------- The plugin provides two command line options to rerun failures from the last ``py.test`` invocation: * ``--lf`` (last failures) - to only re-run the failures. * ``--ff`` (failures first) - to run the failures first and then the rest of the tests. For cleanup (usually not needed), a ``--cache-clear`` option allows to remove all cross-session cache contents ahead of a test run. Other plugins may access the `config.cache`_ object to set/get **json encodable** values between ``py.test`` invocations. .. note:: This plugin is enabled by default, but can be disabled if needed: see :ref:`cmdunregister` (the internal name for this plugin is ``cacheprovider``). Rerunning only failures or failures first ----------------------------------------------- First, let's create 50 test invocation of which only 2 fail:: # content of test_50.py import pytest @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): pytest.fail("bad luck") If you run this for the first time you will see two failures:: $ py.test -q .................F.......F........................ ======= FAILURES ======== _______ test_num[17] ________ i = 17 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed _______ test_num[25] ________ i = 25 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed 2 failed, 48 passed in 0.12 seconds If you then run it with ``--lf``:: $ py.test --lf ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 run-last-failure: rerun last 2 failures rootdir: $REGENDOC_TMPDIR, inifile: collected 50 items test_50.py FF ======= FAILURES ======== _______ test_num[17] ________ i = 17 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed _______ test_num[25] ________ i = 25 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed ======= 2 failed, 48 deselected in 0.12 seconds ======== You have run only the two failing test from the last run, while 48 tests have not been run ("deselected"). Now, if you run with the ``--ff`` option, all tests will be run but the first previous failures will be executed first (as can be seen from the series of ``FF`` and dots):: $ py.test --ff ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 run-last-failure: rerun last 2 failures first rootdir: $REGENDOC_TMPDIR, inifile: collected 50 items test_50.py FF................................................ ======= FAILURES ======== _______ test_num[17] ________ i = 17 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed _______ test_num[25] ________ i = 25 @pytest.mark.parametrize("i", range(50)) def test_num(i): if i in (17, 25): > pytest.fail("bad luck") E Failed: bad luck test_50.py:6: Failed ======= 2 failed, 48 passed in 0.12 seconds ======== .. _`config.cache`: The new config.cache object -------------------------------- .. regendoc:wipe Plugins or conftest.py support code can get a cached value using the pytest ``config`` object. Here is a basic example plugin which implements a :ref:`fixture` which re-uses previously created state across py.test invocations:: # content of test_caching.py import pytest import time @pytest.fixture def mydata(request): val = request.config.cache.get("example/value", None) if val is None: time.sleep(9*0.6) # expensive computation :) val = 42 request.config.cache.set("example/value", val) return val def test_function(mydata): assert mydata == 23 If you run this command once, it will take a while because of the sleep:: $ py.test -q F ======= FAILURES ======== _______ test_function ________ mydata = 42 def test_function(mydata): > assert mydata == 23 E assert 42 == 23 test_caching.py:14: AssertionError 1 failed in 0.12 seconds If you run it a second time the value will be retrieved from the cache and this will be quick:: $ py.test -q F ======= FAILURES ======== _______ test_function ________ mydata = 42 def test_function(mydata): > assert mydata == 23 E assert 42 == 23 test_caching.py:14: AssertionError 1 failed in 0.12 seconds See the `cache-api`_ for more details. Inspecting Cache content ------------------------------- You can always peek at the content of the cache using the ``--cache-clear`` command line option:: $ py.test --cache-clear ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_caching.py F ======= FAILURES ======== _______ test_function ________ mydata = 42 def test_function(mydata): > assert mydata == 23 E assert 42 == 23 test_caching.py:14: AssertionError ======= 1 failed in 0.12 seconds ======== Clearing Cache content ------------------------------- You can instruct pytest to clear all cache files and values by adding the ``--cache-clear`` option like this:: py.test --cache-clear This is recommended for invocations from Continous Integration servers where isolation and correctness is more important than speed. .. _`cache-api`: config.cache API ------------------ The `config.cache`` object allows other plugins, including ``conftest.py`` files, to safely and flexibly store and retrieve values across test runs because the ``config`` object is available in many places. Under the hood, the cache plugin uses the simple dumps/loads API of the json stdlib module .. currentmodule:: _pytest.cacheprovider .. automethod:: Cache.get .. automethod:: Cache.set .. automethod:: Cache.makedir pytest-2.8.7/doc/en/builtin.rst0000664000175000017500000001060312651247335016775 0ustar ronnyronny00000000000000 .. _`pytest helpers`: Pytest API and builtin fixtures ================================================ This is a list of ``pytest.*`` API functions and fixtures. For information on plugin hooks and objects, see :ref:`plugins`. For information on the ``pytest.mark`` mechanism, see :ref:`mark`. For the below objects, you can also interactively ask for help, e.g. by typing on the Python interactive prompt something like:: import pytest help(pytest) .. currentmodule:: pytest Invoking pytest interactively --------------------------------------------------- .. autofunction:: main More examples at :ref:`pytest.main-usage` Helpers for assertions about Exceptions/Warnings -------------------------------------------------------- .. autofunction:: raises Examples at :ref:`assertraises`. .. autofunction:: deprecated_call Raising a specific test outcome -------------------------------------- You can use the following functions in your test, fixture or setup functions to force a certain test outcome. Note that most often you can rather use declarative marks, see :ref:`skipping`. .. autofunction:: _pytest.runner.fail .. autofunction:: _pytest.runner.skip .. autofunction:: _pytest.runner.importorskip .. autofunction:: _pytest.skipping.xfail .. autofunction:: _pytest.runner.exit fixtures and requests ----------------------------------------------------- To mark a fixture function: .. autofunction:: _pytest.python.fixture Tutorial at :ref:`fixtures`. The ``request`` object that can be used from fixture functions. .. autoclass:: _pytest.python.FixtureRequest() :members: .. _builtinfixtures: .. _builtinfuncargs: Builtin fixtures/function arguments ----------------------------------------- You can ask for available builtin or project-custom :ref:`fixtures ` by typing:: $ py.test -q --fixtures cache Return a cache object that can persist state between testing sessions. cache.get(key, default) cache.set(key, value) Keys must be a ``/`` separated value, where the first part is usually the name of your plugin or application to avoid clashes with other cache users. Values can be any object handled by the json stdlib module. capsys enables capturing of writes to sys.stdout/sys.stderr and makes captured output available via ``capsys.readouterr()`` method calls which return a ``(out, err)`` tuple. capfd enables capturing of writes to file descriptors 1 and 2 and makes captured output available via ``capfd.readouterr()`` method calls which return a ``(out, err)`` tuple. record_xml_property Fixture that adds extra xml properties to the tag for the calling test. The fixture is callable with (name, value), with value being automatically xml-encoded. monkeypatch The returned ``monkeypatch`` funcarg provides these helper methods to modify objects, dictionaries or os.environ:: monkeypatch.setattr(obj, name, value, raising=True) monkeypatch.delattr(obj, name, raising=True) monkeypatch.setitem(mapping, name, value) monkeypatch.delitem(obj, name, raising=True) monkeypatch.setenv(name, value, prepend=False) monkeypatch.delenv(name, value, raising=True) monkeypatch.syspath_prepend(path) monkeypatch.chdir(path) All modifications will be undone after the requesting test function has finished.

For this ``argcomplete`` needs to be installed **and** enabled. Install argcomplete using:: sudo pip install 'argcomplete>=0.5.7' For global activation of all argcomplete enabled python applications run:: sudo activate-global-python-argcomplete For permanent (but not global) ``pytest`` activation, use:: register-python-argcomplete py.test >> ~/.bashrc For one-time activation of argcomplete for ``pytest`` only, use:: eval "$(register-python-argcomplete py.test)" pytest-2.8.7/doc/en/assert.rst0000664000175000017500000002302312651247335016630 0ustar ronnyronny00000000000000 The writing and reporting of assertions in tests ================================================== .. _`assertfeedback`: .. _`assert with the assert statement`: .. _`assert`: Asserting with the ``assert`` statement --------------------------------------------------------- ``pytest`` allows you to use the standard python ``assert`` for verifying expectations and values in Python tests. For example, you can write the following:: # content of test_assert1.py def f(): return 3 def test_function(): assert f() == 4 to assert that your function returns a certain value. If this assertion fails you will see the return value of the function call:: $ py.test test_assert1.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_assert1.py F ======= FAILURES ======== _______ test_function ________ def test_function(): > assert f() == 4 E assert 3 == 4 E + where 3 = f() test_assert1.py:5: AssertionError ======= 1 failed in 0.12 seconds ======== ``pytest`` has support for showing the values of the most common subexpressions including calls, attributes, comparisons, and binary and unary operators. (See :ref:`tbreportdemo`). This allows you to use the idiomatic python constructs without boilerplate code while not losing introspection information. However, if you specify a message with the assertion like this:: assert a % 2 == 0, "value was odd, should be even" then no assertion introspection takes places at all and the message will be simply shown in the traceback. See :ref:`assert-details` for more information on assertion introspection. .. _`assertraises`: Assertions about expected exceptions ------------------------------------------ In order to write assertions about raised exceptions, you can use ``pytest.raises`` as a context manager like this:: import pytest def test_zero_division(): with pytest.raises(ZeroDivisionError): 1 / 0 and if you need to have access to the actual exception info you may use:: def test_recursion_depth(): with pytest.raises(RuntimeError) as excinfo: def f(): f() f() assert 'maximum recursion' in str(excinfo.value) ``excinfo`` is a `py.code.ExceptionInfo`_ instance, which is a wrapper around the actual exception raised. The main attributes of interest are ``.type``, ``.value`` and ``.traceback``. .. _py.code.ExceptionInfo: http://pylib.readthedocs.org/en/latest/code.html#py-code-exceptioninfo If you want to write test code that works on Python 2.4 as well, you may also use two other ways to test for an expected exception:: pytest.raises(ExpectedException, func, *args, **kwargs) pytest.raises(ExpectedException, "func(*args, **kwargs)") both of which execute the specified function with args and kwargs and asserts that the given ``ExpectedException`` is raised. The reporter will provide you with helpful output in case of failures such as *no exception* or *wrong exception*. Note that it is also possible to specify a "raises" argument to ``pytest.mark.xfail``, which checks that the test is failing in a more specific way than just having any exception raised:: @pytest.mark.xfail(raises=IndexError) def test_f(): f() Using ``pytest.raises`` is likely to be better for cases where you are testing exceptions your own code is deliberately raising, whereas using ``@pytest.mark.xfail`` with a check function is probably better for something like documenting unfixed bugs (where the test describes what "should" happen) or bugs in dependencies. .. _`assertwarns`: Assertions about expected warnings ----------------------------------------- .. versionadded:: 2.8 You can check that code raises a particular warning using :ref:`pytest.warns `. .. _newreport: Making use of context-sensitive comparisons ------------------------------------------------- .. versionadded:: 2.0 ``pytest`` has rich support for providing context-sensitive information when it encounters comparisons. For example:: # content of test_assert2.py def test_set_comparison(): set1 = set("1308") set2 = set("8035") assert set1 == set2 if you run this module:: $ py.test test_assert2.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_assert2.py F ======= FAILURES ======== _______ test_set_comparison ________ def test_set_comparison(): set1 = set("1308") set2 = set("8035") > assert set1 == set2 E assert set(['0', '1', '3', '8']) == set(['0', '3', '5', '8']) E Extra items in the left set: E '1' E Extra items in the right set: E '5' E Use -v to get the full diff test_assert2.py:5: AssertionError ======= 1 failed in 0.12 seconds ======== Special comparisons are done for a number of cases: * comparing long strings: a context diff is shown * comparing long sequences: first failing indices * comparing dicts: different entries See the :ref:`reporting demo ` for many more examples. Defining your own assertion comparison ---------------------------------------------- It is possible to add your own detailed explanations by implementing the ``pytest_assertrepr_compare`` hook. .. autofunction:: _pytest.hookspec.pytest_assertrepr_compare As an example consider adding the following hook in a conftest.py which provides an alternative explanation for ``Foo`` objects:: # content of conftest.py from test_foocompare import Foo def pytest_assertrepr_compare(op, left, right): if isinstance(left, Foo) and isinstance(right, Foo) and op == "==": return ['Comparing Foo instances:', ' vals: %s != %s' % (left.val, right.val)] now, given this test module:: # content of test_foocompare.py class Foo: def __init__(self, val): self.val = val def __eq__(self, other): return self.val == other.val def test_compare(): f1 = Foo(1) f2 = Foo(2) assert f1 == f2 you can run the test module and get the custom output defined in the conftest file:: $ py.test -q test_foocompare.py F ======= FAILURES ======== _______ test_compare ________ def test_compare(): f1 = Foo(1) f2 = Foo(2) > assert f1 == f2 E assert Comparing Foo instances: E vals: 1 != 2 test_foocompare.py:11: AssertionError 1 failed in 0.12 seconds .. _assert-details: .. _`assert introspection`: Advanced assertion introspection ---------------------------------- .. versionadded:: 2.1 Reporting details about a failing assertion is achieved either by rewriting assert statements before they are run or re-evaluating the assert expression and recording the intermediate values. Which technique is used depends on the location of the assert, ``pytest`` configuration, and Python version being used to run ``pytest``. By default, if the Python version is greater than or equal to 2.6, ``pytest`` rewrites assert statements in test modules. Rewritten assert statements put introspection information into the assertion failure message. ``pytest`` only rewrites test modules directly discovered by its test collection process, so asserts in supporting modules which are not themselves test modules will not be rewritten. .. note:: ``pytest`` rewrites test modules on import. It does this by using an import hook to write a new pyc files. Most of the time this works transparently. However, if you are messing with import yourself, the import hook may interfere. If this is the case, simply use ``--assert=reinterp`` or ``--assert=plain``. Additionally, rewriting will fail silently if it cannot write new pycs, i.e. in a read-only filesystem or a zipfile. If an assert statement has not been rewritten or the Python version is less than 2.6, ``pytest`` falls back on assert reinterpretation. In assert reinterpretation, ``pytest`` walks the frame of the function containing the assert statement to discover sub-expression results of the failing assert statement. You can force ``pytest`` to always use assertion reinterpretation by passing the ``--assert=reinterp`` option. Assert reinterpretation has a caveat not present with assert rewriting: If evaluating the assert expression has side effects you may get a warning that the intermediate values could not be determined safely. A common example of this issue is an assertion which reads from a file:: assert f.read() != '...' If this assertion fails then the re-evaluation will probably succeed! This is because ``f.read()`` will return an empty string when it is called the second time during the re-evaluation. However, it is easy to rewrite the assertion and avoid any trouble:: content = f.read() assert content != '...' All assert introspection can be turned off by passing ``--assert=plain``. For further information, Benjamin Peterson wrote up `Behind the scenes of pytest's new assertion rewriting `_. .. versionadded:: 2.1 Add assert rewriting as an alternate introspection technique. .. versionchanged:: 2.1 Introduce the ``--assert`` option. Deprecate ``--no-assert`` and ``--nomagic``. pytest-2.8.7/doc/en/adopt.rst0000664000175000017500000001007612651247335016442 0ustar ronnyronny00000000000000 April 2015 is "adopt pytest month" ============================================= Are you an enthusiastic pytest user, the local testing guru in your workplace? Or are you considering using pytest for your open source project, but not sure how to get started? Then you may be interested in "adopt pytest month"! We will pair experienced pytest users with open source projects, for a month's effort of getting new development teams started with pytest. In 2015 we are trying this for the first time. In February and March 2015 we will gather volunteers on both sides, in April we will do the work, and in May we will evaluate how it went. This effort is being coordinated by Brianna Laugher. If you have any questions or comments, you can raise them on the `@pytestdotorg twitter account `_ the `issue tracker`_ or the `pytest-dev mailing list`_. .. _`issue tracker`: https://github.com/pytest-dev/pytest/issues/676 .. _`pytest-dev mailing list`: https://mail.python.org/mailman/listinfo/pytest-dev The ideal pytest helper ----------------------------------------- - will be able to commit 2-4 hours a week to working with their particular project (this might involve joining their mailing list, installing the software and exploring any existing tests, offering advice, writing some example tests) - feels confident in using pytest (e.g. has explored command line options, knows how to write parametrized tests, has an idea about conftest contents) - does not need to be an expert in every aspect! `Pytest helpers, sign up here`_! (preferably in February, hard deadline 22 March) .. _`Pytest helpers, sign up here`: http://goo.gl/forms/nxqAhqWt1P The ideal partner project ----------------------------------------- - is open source, and predominantly written in Python - has an automated/documented install process for developers - has more than one core developer - has at least one official release (e.g. is available on pypi) - has the support of the core development team, in trying out pytest adoption - has no tests... or 100% test coverage... or somewhere in between! `Partner projects, sign up here`_! (by 22 March) .. _`Partner projects, sign up here`: http://goo.gl/forms/ZGyqlHiwk3 What does it mean to "adopt pytest"? ----------------------------------------- There can be many different definitions of "success". Pytest can run many `nose and unittest`_ tests by default, so using pytest as your testrunner may be possible from day 1. Job done, right? Progressive success might look like: - tests can be run (by pytest) without errors (there may be failures) - tests can be run (by pytest) without failures - test runner is integrated into CI server - existing tests are rewritten to take advantage of pytest features - this can happen in several iterations, for example: - changing to native assert_ statements (pycmd_ has a script to help with that, ``pyconvert_unittest.py``) - changing `setUp/tearDown methods`_ to fixtures_ - adding markers_ - other changes to reduce boilerplate - assess needs for future tests to be written, e.g. new fixtures, distributed_ testing tweaks "Success" should also include that the development team feels comfortable with their knowledge of how to use pytest. In fact this is probably more important than anything else. So spending a lot of time on communication, giving examples, etc will probably be important - both in running the tests, and in writing them. It may be after the month is up, the partner project decides that pytest is not right for it. That's okay - hopefully the pytest team will also learn something about its weaknesses or deficiencies. .. _`nose and unittest`: faq.html#how-does-pytest-relate-to-nose-and-unittest .. _assert: asserts.html .. _pycmd: https://bitbucket.org/hpk42/pycmd/overview .. _`setUp/tearDown methods`: xunit_setup.html .. _fixtures: fixture.html .. _markers: markers.html .. _distributed: xdist.html Other ways to help ----------------------------------------- Promote!

In fact, ``pytest`` performs an "upwards" search starting from the directory that you specify to be tested and will lookup configuration values right-to-left. You may have options that reside e.g. in your home directory but note that project specific settings will be considered first. There is a flag that helps you debugging your conftest.py configurations:: py.test --traceconfig customizing the collecting and running process ----------------------------------------------- To introduce different test items you can create one or more ``conftest.py`` files in your project. When the collection process traverses directories and modules the default collectors will produce custom Collectors and Items if they are found in a local ``conftest.py`` file. Customizing the collection process in a module ---------------------------------------------- If you have a module where you want to take responsibility for collecting your own test Items and possibly even for executing a test then you can provide `generative tests`_ that yield callables and possibly arguments as a tuple. This is especially useful for calling application test machinery with different parameter sets but counting each of the calls as a separate tests. .. _`generative tests`: features.html#generative-tests The other extension possibility is about specifying a custom test ``Item`` class which is responsible for setting up and executing an underlying test. Or you can extend the collection process for a whole directory tree by putting Items in a ``conftest.py`` configuration file. The collection process dynamically consults the *chain of conftest.py* modules to determine collectors and items at ``Directory``, ``Module``, ``Class``, ``Function`` or ``Generator`` level respectively. Customizing execution of Items and Functions ---------------------------------------------------- - ``pytest.Function`` test items control execution of a test function through its ``function.runtest()`` method. This method is responsible for performing setup and teardown ("Test Fixtures") for a test Function. - ``Function.execute(target, *args)`` methods are invoked by the default ``Function.run()`` to actually execute a python function with the given (usually empty set of) arguments. .. _`py-dev mailing list`: http://codespeak.net/mailman/listinfo/py-dev .. _`test generators`: funcargs.html#test-generators .. _`generative tests`: generative tests: yielding parametrized tests ==================================================== Deprecated since 1.0 in favour of `test generators`_. *Generative tests* are test methods that are *generator functions* which ``yield`` callables and their arguments. This is useful for running a test function multiple times against different parameters. Example:: def test_generative(): for x in (42,17,49): yield check, x def check(arg): assert arg % 7 == 0 # second generated tests fails! Note that ``test_generative()`` will cause three tests to get run, notably ``check(42)``, ``check(17)`` and ``check(49)`` of which the middle one will obviously fail. To make it easier to distinguish the generated tests it is possible to specify an explicit name for them, like for example:: def test_generative(): for x in (42,17,49): yield "case %d" % x, check, x disabling a test class ---------------------- If you want to disable a complete test class you can set the class-level attribute ``disabled``.

After each run ``pytest`` waits until a file in your project changes and then re-runs the previously failing tests. This is repeated until all tests pass after which again a full run is performed. * Load-balancing: if you have multiple CPUs or hosts you can use those for a combined test run. This allows to speed up development or to use special resources of remote machines. * Multi-Platform coverage: you can specify different Python interpreters or different platforms and run tests in parallel on all of them. Before running tests remotely, ``pytest`` efficiently synchronizes your program source code to the remote place. All test results are reported back and displayed to your local test session. You may specify different Python versions and interpreters. .. _`pytest-xdist`: http://pypi.python.org/pypi/pytest-xdist Usage examples --------------------- Speed up test runs by sending tests to multiple CPUs +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ To send tests to multiple CPUs, type:: py.test -n NUM Especially for longer running tests or tests requiring a lot of IO this can lead to considerable speed ups. Running tests in a Python subprocess +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ To instantiate a python2.4 sub process and send tests to it, you may type:: py.test -d --tx popen//python=python2.4 This will start a subprocess which is run with the "python2.4" Python interpreter, found in your system binary lookup path. If you prefix the --tx option value like this:: --tx 3*popen//python=python2.4 then three subprocesses would be created and tests will be load-balanced across these three processes. Sending tests to remote SSH accounts +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Suppose you have a package ``mypkg`` which contains some tests that you can successfully run locally. And you have a ssh-reachable machine ``myhost``. Then you can ad-hoc distribute your tests by typing:: py.test -d --tx ssh=myhostpopen --rsyncdir mypkg mypkg This will synchronize your ``mypkg`` package directory to an remote ssh account and then locally collect tests and send them to remote places for execution. You can specify multiple ``--rsyncdir`` directories to be sent to the remote side. **NOTE:** For ``pytest`` to collect and send tests correctly you not only need to make sure all code and tests directories are rsynced, but that any test (sub) directory also has an ``__init__.py`` file because internally ``pytest`` references tests using their fully qualified python module path. **You will otherwise get strange errors** during setup of the remote side. Sending tests to remote Socket Servers +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Download the single-module `socketserver.py`_ Python program and run it like this:: python socketserver.py It will tell you that it starts listening on the default port. You can now on your home machine specify this new socket host with something like this:: py.test -d --tx socket=192.168.1.102:8888 --rsyncdir mypkg mypkg .. _`atonce`: Running tests on many platforms at once +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ The basic command to run tests on multiple platforms is:: py.test --dist=each --tx=spec1 --tx=spec2 If you specify a windows host, an OSX host and a Linux environment this command will send each tests to all platforms - and report back failures from all platforms at once. The specifications strings use the `xspec syntax`_. .. _`xspec syntax`: http://codespeak.net/execnet/trunk/basics.html#xspec .. _`socketserver.py`: http://codespeak.net/svn/py/dist/py/execnet/script/socketserver.py .. _`execnet`: http://codespeak.net/execnet Specifying test exec environments in a conftest.py +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Instead of specifying command line options, you can put options values in a ``conftest.py`` file like this:: option_tx = ['ssh=myhost//python=python2.5', 'popen//python=python2.5'] option_dist = True Any commandline ``--tx`` specifications will add to the list of available execution environments. Specifying "rsync" dirs in a conftest.py +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ In your ``mypkg/conftest.py`` you may specify directories to synchronise or to exclude:: rsyncdirs = ['.', '../plugins'] rsyncignore = ['_cache'] These directory specifications are relative to the directory where the ``conftest.py`` is found. command line options -------------------- ``-f, --looponfail`` run tests in subprocess, wait for modified files and re-run failing test set until all pass. ``-n numprocesses`` shortcut for '--dist=load --tx=NUM*popen' ``--boxed`` box each test run in a separate process (unix) ``--dist=distmode`` set mode for distributing tests to exec environments. each: send each test to each available environment. load: send each test to one available environment so it is run only once. (default) no: run tests inprocess, don't distribute. ``--tx=xspec`` add a test execution environment. some examples: --tx popen//python=python2.5 --tx socket=192.168.1.102:8888 --tx ssh=user@codespeak.net//chdir=testcache ``-d`` load-balance tests. shortcut for '--dist=load' ``--rsyncdir=dir1`` add directory for rsyncing to remote tx nodes. .. include:: links.txt pytest-2.8.7/doc/en/test/plugin/terminal.rst0000664000175000017500000000206512651247335021422 0ustar ronnyronny00000000000000 Implements terminal reporting of the full testing process. ========================================================== .. contents:: :local: This is a good source for looking at the various reporting hooks. command line options -------------------- ``-v, --verbose`` increase verbosity. ``-r chars`` show extra test summary info as specified by chars (f)ailed, (s)skipped, (x)failed, (X)passed. ``-l, --showlocals`` show locals in tracebacks (disabled by default). ``--report=opts`` (deprecated, use -r) ``--tb=style`` traceback print mode (long/short/line/no). ``--fulltrace`` don't cut any tracebacks (default is to cut). ``--fixtures`` show available function arguments, sorted by plugin Start improving this plugin in 30 seconds ========================================= 1.

Running inside the browsers comes with some speed cost, on the other hand it means for example the code is tested against the real-word DOM implementations. The approach enables to write integration tests such that the JavaScript code is tested against server-side Python code mocked as necessary. Any server-side framework that can already be exposed through WSGI (or for which a subset of WSGI can be written to accommodate the jskit own needs) can play along.

The data file is left at the end of testing so that it is possible to use normal coverage tools to examine it. Limitations ----------- For distributed testing the slaves must have the pytest-cov package installed. This is needed since the plugin must be registered through setuptools / distribute for pytest to start the plugin on the slave. For subprocess measurement environment variables must make it from the main process to the subprocess. The python used by the subprocess must have pytest-cov installed. The subprocess must do normal site initialization so that the environment variables can be detected and coverage started. Acknowledgments ---------------- Holger Krekel for pytest with its distributed testing support. Ned Batchelder for coverage and its ability to combine the coverage results of parallel runs. Whilst this plugin has been built fresh from the ground up to support distributed testing it has been influenced by the work done on pytest-coverage (Ross Lawley, James Mills, Holger Krekel) and nose-cover (Jason Pellerin) which are other coverage plugins for pytest and nose respectively. No doubt others have contributed to these tools as well. command line options -------------------- ``--cov=path`` measure coverage for filesystem path (multi-allowed) ``--cov-report=type`` type of report to generate: term, term-missing, annotate, html, xml (multi-allowed) ``--cov-config=path`` config file for coverage, default: .coveragerc .. include:: links.txt pytest-2.8.7/doc/en/img/0000775000175000017500000000000012651247336015352 5ustar ronnyronny00000000000000pytest-2.8.7/doc/en/img/theuni.png0000664000175000017500000007536412651247335017372 0ustar ronnyronny00000000000000‰PNG  IHDR,ºµÉsRGB®ÎébKGDÿÿÿ ½§“ pHYs  šœtIMEÝ : Œax) IDATxÚìÝwœUÝ?ðï©ÓnÝ–-ÙôP–’„&6Þ,  >Šâó¨(EñAÁÆ#ŠXQšüéR$B-IHÝM6Ùz÷Ö)§ýþØ$$a‰%œ÷+$Ù»wf¾3÷|î9sfcÀ²,˲þ°-eY–eCȲ,˲!dY–eY6„,˲,B–eY–µ³Ð·|…”rÎS/^ðš•ËL¦} Z¥|·¡¾®4T¬”ËÆB!Q’$‰Òc†áÐÐb¨T*•KŒ1LHEZë0 •6®çe²Ùl.—J¥2™L&•áˆªXT*•B¡Ð74Ð0ª)__ Ñ30H˜ÛÞ>VHƒ)IgÒ &ì6kÖa„P»-˲vÍ*rõ•ƒý=¾ËR!¥”ÃwÆd``@ ‰ñÆî”TÊh…ò}o8*•JµZÅßÇ„hc(¥"I8çR*%d­Zu8Ïf2žëºg@„Ƙx^ä …XJîyŒ±Z ©¦Œ¹HooßÂ… žaî9Ÿ>/“ÉÙiY–õŸo»ôóŸÿ´§g½ÑZ+帜q†0pÎÇUJ …$‰c´TR)©”"„8œ3J1­dX«rJêëó¹\6®Ëç³éL:•r#IV«µrYDí8ÌóÇe®ëd²i­d¡0X.—ãA*͘ã8çÆÜh¢5YÛµþ·¿ý•”ÒîH˲¬]­'ôÌ3s C®ãh™F)"€¦”è( ã8rÕZ )´Ö„P„1!!H’¸V­Öª•0¬å²™Æú:)µaVkµ(¬²jÇÀu8PRÈ$Çe 3NpŽÃ]ω*•Z­æ§s£šFeÒYƒ(Â!‚ì!

Here is a basic pattern to achieve this:: # content of test_sample.py def test_answer(cmdopt): if cmdopt == "type1": print ("first") elif cmdopt == "type2": print ("second") assert 0 # to see what was printed For this to work we need to add a command line option and provide the ``cmdopt`` through a :ref:`fixture function `:: # content of conftest.py import pytest def pytest_addoption(parser): parser.addoption("--cmdopt", action="store", default="type1", help="my option: type1 or type2") @pytest.fixture def cmdopt(request): return request.config.getoption("--cmdopt") Let's run this without supplying our new option:: $ py.test -q test_sample.py F ======= FAILURES ======== _______ test_answer ________ cmdopt = 'type1' def test_answer(cmdopt): if cmdopt == "type1": print ("first") elif cmdopt == "type2": print ("second") > assert 0 # to see what was printed E assert 0 test_sample.py:6: AssertionError --------------------------- Captured stdout call --------------------------- first 1 failed in 0.12 seconds And now with supplying a command line option:: $ py.test -q --cmdopt=type2 F ======= FAILURES ======== _______ test_answer ________ cmdopt = 'type2' def test_answer(cmdopt): if cmdopt == "type1": print ("first") elif cmdopt == "type2": print ("second") > assert 0 # to see what was printed E assert 0 test_sample.py:6: AssertionError --------------------------- Captured stdout call --------------------------- second 1 failed in 0.12 seconds You can see that the command line option arrived in our test. This completes the basic pattern. However, one often rather wants to process command line options outside of the test and rather pass in different or more complex objects. Dynamically adding command line options -------------------------------------------------------------- .. regendoc:wipe Through :confval:`addopts` you can statically add command line options for your project. You can also dynamically modify the command line arguments before they get processed:: # content of conftest.py import sys def pytest_cmdline_preparse(args): if 'xdist' in sys.modules: # pytest-xdist plugin import multiprocessing num = max(multiprocessing.cpu_count() / 2, 1) args[:] = ["-n", str(num)] + args If you have the :ref:`xdist plugin ` installed you will now always perform test runs using a number of subprocesses close to your CPU. Running in an empty directory with the above conftest.py:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 0 items ======= no tests ran in 0.12 seconds ======== .. _`excontrolskip`: Control skipping of tests according to command line option -------------------------------------------------------------- .. regendoc:wipe Here is a ``conftest.py`` file adding a ``--runslow`` command line option to control skipping of ``slow`` marked tests:: # content of conftest.py import pytest def pytest_addoption(parser): parser.addoption("--runslow", action="store_true", help="run slow tests") We can now write a test module like this:: # content of test_module.py import pytest slow = pytest.mark.skipif( not pytest.config.getoption("--runslow"), reason="need --runslow option to run" ) def test_func_fast(): pass @slow def test_func_slow(): pass and when running it will see a skipped "slow" test:: $ py.test -rs # "-rs" means report details on the little 's' ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py .s ======= short test summary info ======== SKIP [1] test_module.py:14: need --runslow option to run ======= 1 passed, 1 skipped in 0.12 seconds ======== Or run it including the ``slow`` marked test:: $ py.test --runslow ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py .. ======= 2 passed in 0.12 seconds ======== Writing well integrated assertion helpers -------------------------------------------------- .. regendoc:wipe If you have a test helper function called from a test you can use the ``pytest.fail`` marker to fail a test with a certain message. The test support function will not show up in the traceback if you set the ``__tracebackhide__`` option somewhere in the helper function. Example:: # content of test_checkconfig.py import pytest def checkconfig(x): __tracebackhide__ = True if not hasattr(x, "config"): pytest.fail("not configured: %s" %(x,)) def test_something(): checkconfig(42) The ``__tracebackhide__`` setting influences ``pytest`` showing of tracebacks: the ``checkconfig`` function will not be shown unless the ``--fulltrace`` command line option is specified. Let's run our little function:: $ py.test -q test_checkconfig.py F ======= FAILURES ======== _______ test_something ________ def test_something(): > checkconfig(42) E Failed: not configured: 42 test_checkconfig.py:8: Failed 1 failed in 0.12 seconds Detect if running from within a pytest run -------------------------------------------------------------- .. regendoc:wipe Usually it is a bad idea to make application code behave differently if called from a test. But if you absolutely must find out if your application code is running from a test you can do something like this:: # content of conftest.py def pytest_configure(config): import sys sys._called_from_test = True def pytest_unconfigure(config): del sys._called_from_test and then check for the ``sys._called_from_test`` flag:: if hasattr(sys, '_called_from_test'): # called from within a test run else: # called "normally" accordingly in your application. It's also a good idea to use your own application module rather than ``sys`` for handling flag. Adding info to test report header -------------------------------------------------------------- .. regendoc:wipe It's easy to present extra information in a ``pytest`` run:: # content of conftest.py def pytest_report_header(config): return "project deps: mylib-1.1" which will add the string to the test header accordingly:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 project deps: mylib-1.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 0 items ======= no tests ran in 0.12 seconds ======== .. regendoc:wipe You can also return a list of strings which will be considered as several lines of information. You can of course also make the amount of reporting information on e.g. the value of ``config.option.verbose`` so that you present more information appropriately:: # content of conftest.py def pytest_report_header(config): if config.option.verbose > 0: return ["info1: did you know that ...", "did you?"] which will add info only when run with "--v":: $ py.test -v ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache info1: did you know that ... did you? rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 0 items ======= no tests ran in 0.12 seconds ======== and nothing when run plainly:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 0 items ======= no tests ran in 0.12 seconds ======== profiling test duration -------------------------- .. regendoc:wipe .. versionadded: 2.2 If you have a slow running large test suite you might want to find out which tests are the slowest. Let's make an artificial test suite:: # content of test_some_are_slow.py import time def test_funcfast(): pass def test_funcslow1(): time.sleep(0.1) def test_funcslow2(): time.sleep(0.2) Now we can profile which test functions execute the slowest:: $ py.test --durations=3 ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 3 items test_some_are_slow.py ... ======= slowest 3 test durations ======== 0.20s call test_some_are_slow.py::test_funcslow2 0.10s call test_some_are_slow.py::test_funcslow1 0.00s setup test_some_are_slow.py::test_funcslow2 ======= 3 passed in 0.12 seconds ======== incremental testing - test steps --------------------------------------------------- .. regendoc:wipe Sometimes you may have a testing situation which consists of a series of test steps. If one step fails it makes no sense to execute further steps as they are all expected to fail anyway and their tracebacks add no insight. Here is a simple ``conftest.py`` file which introduces an ``incremental`` marker which is to be used on classes:: # content of conftest.py import pytest def pytest_runtest_makereport(item, call): if "incremental" in item.keywords: if call.excinfo is not None: parent = item.parent parent._previousfailed = item def pytest_runtest_setup(item): if "incremental" in item.keywords: previousfailed = getattr(item.parent, "_previousfailed", None) if previousfailed is not None: pytest.xfail("previous test failed (%s)" %previousfailed.name) These two hook implementations work together to abort incremental-marked tests in a class. Here is a test module example:: # content of test_step.py import pytest @pytest.mark.incremental class TestUserHandling: def test_login(self): pass def test_modification(self): assert 0 def test_deletion(self): pass def test_normal(): pass If we run this:: $ py.test -rx ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_step.py .Fx. ======= short test summary info ======== XFAIL test_step.py::TestUserHandling::()::test_deletion reason: previous test failed (test_modification) ======= FAILURES ======== _______ TestUserHandling.test_modification ________ self = def test_modification(self): > assert 0 E assert 0 test_step.py:9: AssertionError ======= 1 failed, 2 passed, 1 xfailed in 0.12 seconds ======== We'll see that ``test_deletion`` was not executed because ``test_modification`` failed. It is reported as an "expected failure". Package/Directory-level fixtures (setups) ------------------------------------------------------- If you have nested test directories, you can have per-directory fixture scopes by placing fixture functions in a ``conftest.py`` file in that directory You can use all types of fixtures including :ref:`autouse fixtures ` which are the equivalent of xUnit's setup/teardown concept. It's however recommended to have explicit fixture references in your tests or test classes rather than relying on implicitly executing setup/teardown functions, especially if they are far away from the actual tests. Here is a an example for making a ``db`` fixture available in a directory:: # content of a/conftest.py import pytest class DB: pass @pytest.fixture(scope="session") def db(): return DB() and then a test module in that directory:: # content of a/test_db.py def test_a1(db): assert 0, db # to show value another test module:: # content of a/test_db2.py def test_a2(db): assert 0, db # to show value and then a module in a sister directory which will not see the ``db`` fixture:: # content of b/test_error.py def test_root(db): # no db here, will error out pass We can run this:: $ py.test ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 7 items test_step.py .Fx. a/test_db.py F a/test_db2.py F b/test_error.py E ======= ERRORS ======== _______ ERROR at setup of test_root ________ file $REGENDOC_TMPDIR/b/test_error.py, line 1 def test_root(db): # no db here, will error out fixture 'db' not found available fixtures: record_xml_property, pytestconfig, cache, capsys, recwarn, monkeypatch, tmpdir, capfd, tmpdir_factory use 'py.test --fixtures [testpath]' for help on them. $REGENDOC_TMPDIR/b/test_error.py:1 ======= FAILURES ======== _______ TestUserHandling.test_modification ________ self = def test_modification(self): > assert 0 E assert 0 test_step.py:9: AssertionError _______ test_a1 ________ db = def test_a1(db): > assert 0, db # to show value E AssertionError: E assert 0 a/test_db.py:2: AssertionError _______ test_a2 ________ db = def test_a2(db): > assert 0, db # to show value E AssertionError: E assert 0 a/test_db2.py:2: AssertionError ======= 3 failed, 2 passed, 1 xfailed, 1 error in 0.12 seconds ======== The two test modules in the ``a`` directory see the same ``db`` fixture instance while the one test in the sister-directory ``b`` doesn't see it. We could of course also define a ``db`` fixture in that sister directory's ``conftest.py`` file. Note that each fixture is only instantiated if there is a test actually needing it (unless you use "autouse" fixture which are always executed ahead of the first test executing). post-process test reports / failures --------------------------------------- If you want to postprocess test reports and need access to the executing environment you can implement a hook that gets called when the test "report" object is about to be created. Here we write out all failing test calls and also access a fixture (if it was used by the test) in case you want to query/look at it during your post processing. In our case we just write some informations out to a ``failures`` file:: # content of conftest.py import pytest import os.path @pytest.hookimpl(tryfirst=True, hookwrapper=True) def pytest_runtest_makereport(item, call): # execute all other hooks to obtain the report object outcome = yield rep = outcome.get_result() # we only look at actual failing test calls, not setup/teardown if rep.when == "call" and rep.failed: mode = "a" if os.path.exists("failures") else "w" with open("failures", mode) as f: # let's also access a fixture for the fun of it if "tmpdir" in item.fixturenames: extra = " (%s)" % item.funcargs["tmpdir"] else: extra = "" f.write(rep.nodeid + extra + "\n") if you then have failing tests:: # content of test_module.py def test_fail1(tmpdir): assert 0 def test_fail2(): assert 0 and run them:: $ py.test test_module.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py FF ======= FAILURES ======== _______ test_fail1 ________ tmpdir = local('PYTEST_TMPDIR/test_fail10') def test_fail1(tmpdir): > assert 0 E assert 0 test_module.py:2: AssertionError _______ test_fail2 ________ def test_fail2(): > assert 0 E assert 0 test_module.py:4: AssertionError ======= 2 failed in 0.12 seconds ======== you will have a "failures" file which contains the failing test ids:: $ cat failures test_module.py::test_fail1 (PYTEST_TMPDIR/test_fail10) test_module.py::test_fail2 Making test result information available in fixtures ----------------------------------------------------------- .. regendoc:wipe If you want to make test result reports available in fixture finalizers here is a little example implemented via a local plugin:: # content of conftest.py import pytest @pytest.hookimpl(tryfirst=True, hookwrapper=True) def pytest_runtest_makereport(item, call): # execute all other hooks to obtain the report object outcome = yield rep = outcome.get_result() # set an report attribute for each phase of a call, which can # be "setup", "call", "teardown" setattr(item, "rep_" + rep.when, rep) @pytest.fixture def something(request): def fin(): # request.node is an "item" because we use the default # "function" scope if request.node.rep_setup.failed: print ("setting up a test failed!", request.node.nodeid) elif request.node.rep_setup.passed: if request.node.rep_call.failed: print ("executing test failed", request.node.nodeid) request.addfinalizer(fin) if you then have failing tests:: # content of test_module.py import pytest @pytest.fixture def other(): assert 0 def test_setup_fails(something, other): pass def test_call_fails(something): assert 0 def test_fail2(): assert 0 and run it:: $ py.test -s test_module.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 3 items test_module.py Esetting up a test failed! test_module.py::test_setup_fails Fexecuting test failed test_module.py::test_call_fails F ======= ERRORS ======== _______ ERROR at setup of test_setup_fails ________ @pytest.fixture def other(): > assert 0 E assert 0 test_module.py:6: AssertionError ======= FAILURES ======== _______ test_call_fails ________ something = None def test_call_fails(something): > assert 0 E assert 0 test_module.py:12: AssertionError _______ test_fail2 ________ def test_fail2(): > assert 0 E assert 0 test_module.py:15: AssertionError ======= 2 failed, 1 error in 0.12 seconds ======== You'll see that the fixture finalizers could use the precise reporting information. Integrating pytest runner and cx_freeze ----------------------------------------------------------- If you freeze your application using a tool like `cx_freeze `_ in order to distribute it to your end-users, it is a good idea to also package your test runner and run your tests using the frozen application. This way packaging errors such as dependencies not being included into the executable can be detected early while also allowing you to send test files to users so they can run them in their machines, which can be invaluable to obtain more information about a hard to reproduce bug. Unfortunately ``cx_freeze`` can't discover them automatically because of ``pytest``'s use of dynamic module loading, so you must declare them explicitly by using ``pytest.freeze_includes()``:: # contents of setup.py from cx_Freeze import setup, Executable import pytest setup( name="app_main", executables=[Executable("app_main.py")], options={"build_exe": { 'includes': pytest.freeze_includes()} }, # ... other options ) If you don't want to ship a different executable just in order to run your tests, you can make your program check for a certain flag and pass control over to ``pytest`` instead. For example:: # contents of app_main.py import sys if len(sys.argv) > 1 and sys.argv[1] == '--pytest': import pytest sys.exit(pytest.main(sys.argv[2:])) else: # normal application execution: at this point argv can be parsed # by your argument-parsing library of choice as usual ... This makes it convenient to execute your tests from within your frozen application, using standard ``py.test`` command-line options:: ./app_main --pytest --verbose --tb=long --junit-xml=results.xml

=============================================== Ignore paths during test collection ----------------------------------- You can easily ignore certain test directories and modules during collection by passing the ``--ignore=path`` option on the cli. ``pytest`` allows multiple ``--ignore`` options. Example:: tests/ ├── example │   ├── test_example_01.py │   ├── test_example_02.py │   └── test_example_03.py ├── foobar │   ├── test_foobar_01.py │   ├── test_foobar_02.py │   └── test_foobar_03.py └── hello └── world ├── test_world_01.py ├── test_world_02.py └── test_world_03.py Now if you invoke ``pytest`` with ``--ignore=tests/foobar/test_foobar_03.py --ignore=tests/hello/``, you will see that ``pytest`` only collects test-modules, which do not match the patterns specified:: ========= test session starts ========== platform darwin -- Python 2.7.10, pytest-2.8.2, py-1.4.30, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 5 items tests/example/test_example_01.py . tests/example/test_example_02.py . tests/example/test_example_03.py . tests/foobar/test_foobar_01.py . tests/foobar/test_foobar_02.py . ======= 5 passed in 0.02 seconds ======= Changing directory recursion ----------------------------------------------------- You can set the :confval:`norecursedirs` option in an ini-file, for example your ``setup.cfg`` in the project root directory:: # content of setup.cfg [pytest] norecursedirs = .svn _build tmp* This would tell ``pytest`` to not recurse into typical subversion or sphinx-build directories or into any ``tmp`` prefixed directory. .. _`change naming conventions`: Changing naming conventions ----------------------------------------------------- You can configure different naming conventions by setting the :confval:`python_files`, :confval:`python_classes` and :confval:`python_functions` configuration options. Example:: # content of setup.cfg # can also be defined in in tox.ini or pytest.ini file [pytest] python_files=check_*.py python_classes=Check python_functions=*_check This would make ``pytest`` look for tests in files that match the ``check_* .py`` glob-pattern, ``Check`` prefixes in classes, and functions and methods that match ``*_check``. For example, if we have:: # content of check_myapp.py class CheckMyApp: def simple_check(self): pass def complex_check(self): pass then the test collection looks like this:: $ py.test --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: setup.cfg collected 2 items ======= no tests ran in 0.12 seconds ======== .. note:: the ``python_functions`` and ``python_classes`` options has no effect for ``unittest.TestCase`` test discovery because pytest delegates detection of test case methods to unittest code. Interpreting cmdline arguments as Python packages ----------------------------------------------------- You can use the ``--pyargs`` option to make ``pytest`` try interpreting arguments as python package names, deriving their file system path and then running the test. For example if you have unittest2 installed you can type:: py.test --pyargs unittest2.test.test_skipping -q which would run the respective test module. Like with other options, through an ini-file and the :confval:`addopts` option you can make this change more permanently:: # content of pytest.ini [pytest] addopts = --pyargs Now a simple invocation of ``py.test NAME`` will check if NAME exists as an importable package/module and otherwise treat it as a filesystem path. Finding out what is collected ----------------------------------------------- You can always peek at the collection tree without running tests like this:: . $ py.test --collect-only pythoncollection.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: pytest.ini collected 3 items ======= no tests ran in 0.12 seconds ======== customizing test collection to find all .py files --------------------------------------------------------- .. regendoc:wipe You can easily instruct ``pytest`` to discover tests from every python file:: # content of pytest.ini [pytest] python_files = *.py However, many projects will have a ``setup.py`` which they don't want to be imported. Moreover, there may files only importable by a specific python version. For such cases you can dynamically define files to be ignored by listing them in a ``conftest.py`` file:: # content of conftest.py import sys collect_ignore = ["setup.py"] if sys.version_info[0] > 2: collect_ignore.append("pkg/module_py2.py") And then if you have a module file like this:: # content of pkg/module_py2.py def test_only_on_python2(): try: assert 0 except Exception, e: pass and a setup.py dummy file like this:: # content of setup.py 0/0 # will raise exception if imported then a pytest run on python2 will find the one test when run with a python2 interpreters and will leave out the setup.py file:: $ py.test --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: pytest.ini collected 0 items ======= no tests ran in 0.12 seconds ======== If you run with a Python3 interpreter the moduled added through the conftest.py file will not be considered for test collection. pytest-2.8.7/doc/en/example/pythoncollection.py0000664000175000017500000000030712651247335022177 0ustar ronnyronny00000000000000 # run this with $ py.test --collect-only test_collectonly.py # def test_function(): pass class TestClass: def test_method(self): pass def test_anothermethod(self): pass pytest-2.8.7/doc/en/example/parametrize.rst0000664000175000017500000003654312651247335021320 0ustar ronnyronny00000000000000 .. _paramexamples: Parametrizing tests ================================================= .. currentmodule:: _pytest.python ``pytest`` allows to easily parametrize test functions. For basic docs, see :ref:`parametrize-basics`. In the following we provide some examples using the builtin mechanisms. Generating parameters combinations, depending on command line ---------------------------------------------------------------------------- .. regendoc:wipe Let's say we want to execute a test with different computation parameters and the parameter range shall be determined by a command line argument. Let's first write a simple (do-nothing) computation test:: # content of test_compute.py def test_compute(param1): assert param1 < 4 Now we add a test configuration like this:: # content of conftest.py def pytest_addoption(parser): parser.addoption("--all", action="store_true", help="run all combinations") def pytest_generate_tests(metafunc): if 'param1' in metafunc.fixturenames: if metafunc.config.option.all: end = 5 else: end = 2 metafunc.parametrize("param1", range(end)) This means that we only run 2 tests if we do not pass ``--all``:: $ py.test -q test_compute.py .. 2 passed in 0.12 seconds We run only two computations, so we see two dots. let's run the full monty:: $ py.test -q --all ....F ======= FAILURES ======== _______ test_compute[4] ________ param1 = 4 def test_compute(param1): > assert param1 < 4 E assert 4 < 4 test_compute.py:3: AssertionError 1 failed, 4 passed in 0.12 seconds As expected when running the full range of ``param1`` values we'll get an error on the last one. Different options for test IDs ------------------------------------ pytest will build a string that is the test ID for each set of values in a parametrized test. These IDs can be used with ``-k`` to select specific cases to run, and they will also identify the specific case when one is failing. Running pytest with ``--collect-only`` will show the generated IDs. Numbers, strings, booleans and None will have their usual string representation used in the test ID. For other objects, pytest will make a string based on the argument name:: # content of test_time.py import pytest from datetime import datetime, timedelta testdata = [ (datetime(2001, 12, 12), datetime(2001, 12, 11), timedelta(1)), (datetime(2001, 12, 11), datetime(2001, 12, 12), timedelta(-1)), ] @pytest.mark.parametrize("a,b,expected", testdata) def test_timedistance_v0(a, b, expected): diff = a - b assert diff == expected @pytest.mark.parametrize("a,b,expected", testdata, ids=["forward", "backward"]) def test_timedistance_v1(a, b, expected): diff = a - b assert diff == expected def idfn(val): if isinstance(val, (datetime,)): # note this wouldn't show any hours/minutes/seconds return val.strftime('%Y%m%d') @pytest.mark.parametrize("a,b,expected", testdata, ids=idfn) def test_timedistance_v2(a, b, expected): diff = a - b assert diff == expected In ``test_timedistance_v0``, we let pytest generate the test IDs. In ``test_timedistance_v1``, we specified ``ids`` as a list of strings which were used as the test IDs. These are succinct, but can be a pain to maintain. In ``test_timedistance_v2``, we specified ``ids`` as a function that can generate a string representation to make part of the test ID. So our ``datetime`` values use the label generated by ``idfn``, but because we didn't generate a label for ``timedelta`` objects, they are still using the default pytest representation:: $ py.test test_time.py --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 6 items ======= no tests ran in 0.12 seconds ======== A quick port of "testscenarios" ------------------------------------ .. _`test scenarios`: http://pypi.python.org/pypi/testscenarios/ Here is a quick port to run tests configured with `test scenarios`_, an add-on from Robert Collins for the standard unittest framework. We only have to work a bit to construct the correct arguments for pytest's :py:func:`Metafunc.parametrize`:: # content of test_scenarios.py def pytest_generate_tests(metafunc): idlist = [] argvalues = [] for scenario in metafunc.cls.scenarios: idlist.append(scenario[0]) items = scenario[1].items() argnames = [x[0] for x in items] argvalues.append(([x[1] for x in items])) metafunc.parametrize(argnames, argvalues, ids=idlist, scope="class") scenario1 = ('basic', {'attribute': 'value'}) scenario2 = ('advanced', {'attribute': 'value2'}) class TestSampleWithScenarios: scenarios = [scenario1, scenario2] def test_demo1(self, attribute): assert isinstance(attribute, str) def test_demo2(self, attribute): assert isinstance(attribute, str) this is a fully self-contained example which you can run with:: $ py.test test_scenarios.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_scenarios.py .... ======= 4 passed in 0.12 seconds ======== If you just collect tests you'll also nicely see 'advanced' and 'basic' as variants for the test function:: $ py.test --collect-only test_scenarios.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items ======= no tests ran in 0.12 seconds ======== Note that we told ``metafunc.parametrize()`` that your scenario values should be considered class-scoped. With pytest-2.3 this leads to a resource-based ordering. Deferring the setup of parametrized resources --------------------------------------------------- .. regendoc:wipe The parametrization of test functions happens at collection time. It is a good idea to setup expensive resources like DB connections or subprocess only when the actual test is run. Here is a simple example how you can achieve that, first the actual test requiring a ``db`` object:: # content of test_backends.py import pytest def test_db_initialized(db): # a dummy test if db.__class__.__name__ == "DB2": pytest.fail("deliberately failing for demo purposes") We can now add a test configuration that generates two invocations of the ``test_db_initialized`` function and also implements a factory that creates a database object for the actual test invocations:: # content of conftest.py import pytest def pytest_generate_tests(metafunc): if 'db' in metafunc.fixturenames: metafunc.parametrize("db", ['d1', 'd2'], indirect=True) class DB1: "one database object" class DB2: "alternative database object" @pytest.fixture def db(request): if request.param == "d1": return DB1() elif request.param == "d2": return DB2() else: raise ValueError("invalid internal test config") Let's first see how it looks like at collection time:: $ py.test test_backends.py --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items ======= no tests ran in 0.12 seconds ======== And then when we run the test:: $ py.test -q test_backends.py .F ======= FAILURES ======== _______ test_db_initialized[d2] ________ db = def test_db_initialized(db): # a dummy test if db.__class__.__name__ == "DB2": > pytest.fail("deliberately failing for demo purposes") E Failed: deliberately failing for demo purposes test_backends.py:6: Failed 1 failed, 1 passed in 0.12 seconds The first invocation with ``db == "DB1"`` passed while the second with ``db == "DB2"`` failed. Our ``db`` fixture function has instantiated each of the DB values during the setup phase while the ``pytest_generate_tests`` generated two according calls to the ``test_db_initialized`` during the collection phase. .. regendoc:wipe Apply indirect on particular arguments --------------------------------------------------- Very often parametrization uses more than one argument name. There is opportunity to apply ``indirect`` parameter on particular arguments. It can be done by passing list or tuple of arguments' names to ``indirect``. In the example below there is a function ``test_indirect`` which uses two fixtures: ``x`` and ``y``. Here we give to indirect the list, which contains the name of the fixture ``x``. The indirect parameter will be applied to this argument only, and the value ``a`` will be passed to respective fixture function:: # content of test_indirect_list.py import pytest @pytest.fixture(scope='function') def x(request): return request.param * 3 @pytest.fixture(scope='function') def y(request): return request.param * 2 @pytest.mark.parametrize('x, y', [('a', 'b')], indirect=['x']) def test_indirect(x,y): assert x == 'aaa' assert y == 'b' The result of this test will be successful:: $ py.test test_indirect_list.py --collect-only ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items ======= no tests ran in 0.12 seconds ======== .. regendoc:wipe Parametrizing test methods through per-class configuration -------------------------------------------------------------- .. _`unittest parametrizer`: https://github.com/testing-cabal/unittest-ext/blob/master/params.py Here is an example ``pytest_generate_function`` function implementing a parametrization scheme similar to Michael Foord's `unittest parametrizer`_ but in a lot less code:: # content of ./test_parametrize.py import pytest def pytest_generate_tests(metafunc): # called once per each test function funcarglist = metafunc.cls.params[metafunc.function.__name__] argnames = list(funcarglist[0]) metafunc.parametrize(argnames, [[funcargs[name] for name in argnames] for funcargs in funcarglist]) class TestClass: # a map specifying multiple argument sets for a test method params = { 'test_equals': [dict(a=1, b=2), dict(a=3, b=3), ], 'test_zerodivision': [dict(a=1, b=0), ], } def test_equals(self, a, b): assert a == b def test_zerodivision(self, a, b): pytest.raises(ZeroDivisionError, "a/b") Our test generator looks up a class-level definition which specifies which argument sets to use for each test function.

We define a ``test_basic_objects`` function which is to be run with different sets of arguments for its three arguments: * ``python1``: first python interpreter, run to pickle-dump an object to a file * ``python2``: second interpreter, run to pickle-load an object from a file * ``obj``: object to be dumped/loaded .. literalinclude:: multipython.py Running it results in some skips if we don't have all the python interpreters installed and otherwise runs all combinations (5 interpreters times 5 interpreters times 3 objects to serialize/deserialize):: . $ py.test -rs -q multipython.py ........................... 27 passed in 0.12 seconds Indirect parametrization of optional implementations/imports -------------------------------------------------------------------- If you want to compare the outcomes of several implementations of a given API, you can write test functions that receive the already imported implementations and get skipped in case the implementation is not importable/available. Let's say we have a "base" implementation and the other (possibly optimized ones) need to provide similar results:: # content of conftest.py import pytest @pytest.fixture(scope="session") def basemod(request): return pytest.importorskip("base") @pytest.fixture(scope="session", params=["opt1", "opt2"]) def optmod(request): return pytest.importorskip(request.param) And then a base implementation of a simple function:: # content of base.py def func1(): return 1 And an optimized version:: # content of opt1.py def func1(): return 1.0001 And finally a little test module:: # content of test_module.py def test_func1(basemod, optmod): assert round(basemod.func1(), 3) == round(optmod.func1(), 3) If you run this with reporting for skips enabled:: $ py.test -rs test_module.py ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 2 items test_module.py .s ======= short test summary info ======== SKIP [1] $REGENDOC_TMPDIR/conftest.py:10: could not import 'opt2' ======= 1 passed, 1 skipped in 0.12 seconds ======== You'll see that we don't have a ``opt2`` module and thus the second test run of our ``test_func1`` was skipped. A few notes: - the fixture functions in the ``conftest.py`` file are "session-scoped" because we don't need to import more than once - if you have multiple test functions and a skipped import, you will see the ``[1]`` count increasing in the report - you can put :ref:`@pytest.mark.parametrize <@pytest.mark.parametrize>` style parametrization on the test functions to parametrize input/output values as well. pytest-2.8.7/doc/en/example/nonpython.rst0000664000175000017500000000602412651247335021020 0ustar ronnyronny00000000000000 .. _`non-python tests`: Working with non-python tests ==================================================== .. _`yaml plugin`: A basic example for specifying tests in Yaml files -------------------------------------------------------------- .. _`pytest-yamlwsgi`: http://bitbucket.org/aafshar/pytest-yamlwsgi/src/tip/pytest_yamlwsgi.py .. _`PyYAML`: http://pypi.python.org/pypi/PyYAML/ Here is an example ``conftest.py`` (extracted from Ali Afshnars special purpose `pytest-yamlwsgi`_ plugin).

Marking test functions and selecting them for a run ---------------------------------------------------- You can "mark" a test function with custom metadata like this:: # content of test_server.py import pytest @pytest.mark.webtest def test_send_http(): pass # perform some webtest test for your app def test_something_quick(): pass def test_another(): pass class TestClass: def test_method(self): pass .. versionadded:: 2.2 You can then restrict a test run to only run tests marked with ``webtest``:: $ py.test -v -m webtest ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::test_send_http PASSED ======= 3 tests deselected by "-m 'webtest'" ======== ======= 1 passed, 3 deselected in 0.12 seconds ======== Or the inverse, running all tests except the webtest ones:: $ py.test -v -m "not webtest" ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::test_something_quick PASSED test_server.py::test_another PASSED test_server.py::TestClass::test_method PASSED ======= 1 tests deselected by "-m 'not webtest'" ======== ======= 3 passed, 1 deselected in 0.12 seconds ======== Selecting tests based on their node ID -------------------------------------- You can provide one or more :ref:`node IDs ` as positional arguments to select only specified tests. This makes it easy to select tests based on their module, class, method, or function name:: $ py.test -v test_server.py::TestClass::test_method ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 5 items test_server.py::TestClass::test_method PASSED ======= 1 passed in 0.12 seconds ======== You can also select on the class:: $ py.test -v test_server.py::TestClass ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::TestClass::test_method PASSED ======= 1 passed in 0.12 seconds ======== Or select multiple nodes:: $ py.test -v test_server.py::TestClass test_server.py::test_send_http ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 8 items test_server.py::TestClass::test_method PASSED test_server.py::test_send_http PASSED ======= 2 passed in 0.12 seconds ======== .. _node-id: .. note:: Node IDs are of the form ``module.py::class::method`` or ``module.py::function``. Node IDs control which tests are collected, so ``module.py::class`` will select all test methods on the class. Nodes are also created for each parameter of a parametrized fixture or test, so selecting a parametrized test must include the parameter value, e.g. ``module.py::function[param]``. Node IDs for failing tests are displayed in the test summary info when running py.test with the ``-rf`` option. You can also construct Node IDs from the output of ``py.test --collectonly``. Using ``-k expr`` to select tests based on their name ------------------------------------------------------- .. versionadded: 2.0/2.3.4 You can use the ``-k`` command line option to specify an expression which implements a substring match on the test names instead of the exact match on markers that ``-m`` provides. This makes it easy to select tests based on their names:: $ py.test -v -k http # running with the above defined example module ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::test_send_http PASSED ======= 3 tests deselected by '-khttp' ======== ======= 1 passed, 3 deselected in 0.12 seconds ======== And you can also run all tests except the ones that match the keyword:: $ py.test -k "not send_http" -v ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::test_something_quick PASSED test_server.py::test_another PASSED test_server.py::TestClass::test_method PASSED ======= 1 tests deselected by '-knot send_http' ======== ======= 3 passed, 1 deselected in 0.12 seconds ======== Or to select "http" and "quick" tests:: $ py.test -k "http or quick" -v ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 -- $PYTHON_PREFIX/bin/python3.4 cachedir: .cache rootdir: $REGENDOC_TMPDIR, inifile: collecting ... collected 4 items test_server.py::test_send_http PASSED test_server.py::test_something_quick PASSED ======= 2 tests deselected by '-khttp or quick' ======== ======= 2 passed, 2 deselected in 0.12 seconds ======== .. note:: If you are using expressions such as "X and Y" then both X and Y need to be simple non-keyword names. For example, "pass" or "from" will result in SyntaxErrors because "-k" evaluates the expression. However, if the "-k" argument is a simple string, no such restrictions apply. Also "-k 'not STRING'" has no restrictions. You can also specify numbers like "-k 1.3" to match tests which are parametrized with the float "1.3". Registering markers ------------------------------------- .. versionadded:: 2.2 .. ini-syntax for custom markers: Registering markers for your test suite is simple:: # content of pytest.ini [pytest] markers = webtest: mark a test as a webtest. You can ask which markers exist for your test suite - the list includes our just defined ``webtest`` markers:: $ py.test --markers @pytest.mark.webtest: mark a test as a webtest. @pytest.mark.skipif(condition): skip the given test function if eval(condition) results in a True value. Evaluation happens within the module global context. Example: skipif('sys.platform == "win32"') skips the test if we are on the win32 platform. see http://pytest.org/latest/skipping.html @pytest.mark.xfail(condition, reason=None, run=True, raises=None): mark the the test function as an expected failure if eval(condition) has a True value. Optionally specify a reason for better reporting and run=False if you don't even want to execute the test function. If only specific exception(s) are expected, you can list them in raises, and if the test fails in other ways, it will be reported as a true failure. See http://pytest.org/latest/skipping.html @pytest.mark.parametrize(argnames, argvalues): call a test function multiple times passing in different arguments in turn. argvalues generally needs to be a list of values if argnames specifies only one name or a list of tuples of values if argnames specifies multiple names. Example: @parametrize('arg1', [1,2]) would lead to two calls of the decorated test function, one with arg1=1 and another with arg1=2.see http://pytest.org/latest/parametrize.html for more info and examples. @pytest.mark.usefixtures(fixturename1, fixturename2, ...): mark tests as needing all of the specified fixtures. see http://pytest.org/latest/fixture.html#usefixtures @pytest.mark.tryfirst: mark a hook implementation function such that the plugin machinery will try to call it first/as early as possible. @pytest.mark.trylast: mark a hook implementation function such that the plugin machinery will try to call it last/as late as possible. For an example on how to add and work with markers from a plugin, see :ref:`adding a custom marker from a plugin`. .. note:: It is recommended to explicitly register markers so that: * there is one place in your test suite defining your markers * asking for existing markers via ``py.test --markers`` gives good output * typos in function markers are treated as an error if you use the ``--strict`` option. Future versions of ``pytest`` are probably going to start treating non-registered markers as errors at some point. .. _`scoped-marking`: Marking whole classes or modules ---------------------------------------------------- If you are programming with Python 2.6 or later you may use ``pytest.mark`` decorators with classes to apply markers to all of its test methods:: # content of test_mark_classlevel.py import pytest @pytest.mark.webtest class TestClass: def test_startup(self): pass def test_startup_and_more(self): pass This is equivalent to directly applying the decorator to the two test functions. To remain backward-compatible with Python 2.4 you can also set a ``pytestmark`` attribute on a TestClass like this:: import pytest class TestClass: pytestmark = pytest.mark.webtest or if you need to use multiple markers you can use a list:: import pytest class TestClass: pytestmark = [pytest.mark.webtest, pytest.mark.slowtest] You can also set a module level marker:: import pytest pytestmark = pytest.mark.webtest in which case it will be applied to all functions and methods defined in the module. .. _`marking individual tests when using parametrize`: Marking individual tests when using parametrize ----------------------------------------------- When using parametrize, applying a mark will make it apply to each individual test. However it is also possible to apply a marker to an individual test instance:: import pytest @pytest.mark.foo @pytest.mark.parametrize(("n", "expected"), [ (1, 2), pytest.mark.bar((1, 3)), (2, 3), ]) def test_increment(n, expected): assert n + 1 == expected In this example the mark "foo" will apply to each of the three tests, whereas the "bar" mark is only applied to the second test. Skip and xfail marks can also be applied in this way, see :ref:`skip/xfail with parametrize`. .. note:: If the data you are parametrizing happen to be single callables, you need to be careful when marking these items. `pytest.mark.xfail(my_func)` won't work because it's also the signature of a function being decorated. To resolve this ambiguity, you need to pass a reason argument: `pytest.mark.xfail(func_bar, reason="Issue#7")`. .. _`adding a custom marker from a plugin`: Custom marker and command line option to control test runs ---------------------------------------------------------- .. regendoc:wipe Plugins can provide custom markers and implement specific behaviour based on it. This is a self-contained example which adds a command line option and a parametrized test function marker to run tests specifies via named environments:: # content of conftest.py import pytest def pytest_addoption(parser): parser.addoption("-E", action="store", metavar="NAME", help="only run tests matching the environment NAME.") def pytest_configure(config): # register an additional marker config.addinivalue_line("markers", "env(name): mark test to run only on named environment") def pytest_runtest_setup(item): envmarker = item.get_marker("env") if envmarker is not None: envname = envmarker.args[0] if envname != item.config.getoption("-E"): pytest.skip("test requires env %r" % envname) A test file using this local plugin:: # content of test_someenv.py import pytest @pytest.mark.env("stage1") def test_basic_db_operation(): pass and an example invocations specifying a different environment than what the test needs:: $ py.test -E stage2 ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_someenv.py s ======= 1 skipped in 0.12 seconds ======== and here is one that specifies exactly the environment needed:: $ py.test -E stage1 ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 1 items test_someenv.py . ======= 1 passed in 0.12 seconds ======== The ``--markers`` option always gives you a list of available markers:: $ py.test --markers @pytest.mark.env(name): mark test to run only on named environment @pytest.mark.skipif(condition): skip the given test function if eval(condition) results in a True value. Evaluation happens within the module global context. Example: skipif('sys.platform == "win32"') skips the test if we are on the win32 platform. see http://pytest.org/latest/skipping.html @pytest.mark.xfail(condition, reason=None, run=True, raises=None): mark the the test function as an expected failure if eval(condition) has a True value. Optionally specify a reason for better reporting and run=False if you don't even want to execute the test function. If only specific exception(s) are expected, you can list them in raises, and if the test fails in other ways, it will be reported as a true failure. See http://pytest.org/latest/skipping.html @pytest.mark.parametrize(argnames, argvalues): call a test function multiple times passing in different arguments in turn. argvalues generally needs to be a list of values if argnames specifies only one name or a list of tuples of values if argnames specifies multiple names. Example: @parametrize('arg1', [1,2]) would lead to two calls of the decorated test function, one with arg1=1 and another with arg1=2.see http://pytest.org/latest/parametrize.html for more info and examples. @pytest.mark.usefixtures(fixturename1, fixturename2, ...): mark tests as needing all of the specified fixtures. see http://pytest.org/latest/fixture.html#usefixtures @pytest.mark.tryfirst: mark a hook implementation function such that the plugin machinery will try to call it first/as early as possible. @pytest.mark.trylast: mark a hook implementation function such that the plugin machinery will try to call it last/as late as possible. Reading markers which were set from multiple places ---------------------------------------------------- .. versionadded: 2.2.2 .. regendoc:wipe If you are heavily using markers in your test suite you may encounter the case where a marker is applied several times to a test function. From plugin code you can read over all such settings. Example:: # content of test_mark_three_times.py import pytest pytestmark = pytest.mark.glob("module", x=1) @pytest.mark.glob("class", x=2) class TestClass: @pytest.mark.glob("function", x=3) def test_something(self): pass Here we have the marker "glob" applied three times to the same test function. From a conftest file we can read it like this:: # content of conftest.py import sys def pytest_runtest_setup(item): g = item.get_marker("glob") if g is not None: for info in g: print ("glob args=%s kwargs=%s" %(info.args, info.kwargs)) sys.stdout.flush() Let's run this without capturing output and see what we get:: $ py.test -q -s glob args=('function',) kwargs={'x': 3} glob args=('class',) kwargs={'x': 2} glob args=('module',) kwargs={'x': 1} . 1 passed in 0.12 seconds marking platform specific tests with pytest -------------------------------------------------------------- .. regendoc:wipe Consider you have a test suite which marks tests for particular platforms, namely ``pytest.mark.darwin``, ``pytest.mark.win32`` etc. and you also have tests that run on all platforms and have no specific marker. If you now want to have a way to only run the tests for your particular platform, you could use the following plugin:: # content of conftest.py # import sys import pytest ALL = set("darwin linux2 win32".split()) def pytest_runtest_setup(item): if isinstance(item, item.Function): plat = sys.platform if not item.get_marker(plat): if ALL.intersection(item.keywords): pytest.skip("cannot run on platform %s" %(plat)) then tests will be skipped if they were specified for a different platform. Let's do a little test file to show how this looks like:: # content of test_plat.py import pytest @pytest.mark.darwin def test_if_apple_is_evil(): pass @pytest.mark.linux2 def test_if_linux_works(): pass @pytest.mark.win32 def test_if_win32_crashes(): pass def test_runs_everywhere(): pass then you will see two test skipped and two executed tests as expected:: $ py.test -rs # this option reports skip reasons ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_plat.py sss. ======= short test summary info ======== SKIP [3] $REGENDOC_TMPDIR/conftest.py:12: cannot run on platform linux ======= 1 passed, 3 skipped in 0.12 seconds ======== Note that if you specify a platform via the marker-command line option like this:: $ py.test -m linux2 ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_plat.py s ======= 3 tests deselected by "-m 'linux2'" ======== ======= 1 skipped, 3 deselected in 0.12 seconds ======== then the unmarked-tests will not be run. It is thus a way to restrict the run to the specific tests. Automatically adding markers based on test names -------------------------------------------------------- .. regendoc:wipe If you a test suite where test function names indicate a certain type of test, you can implement a hook that automatically defines markers so that you can use the ``-m`` option with it. Let's look at this test module:: # content of test_module.py def test_interface_simple(): assert 0 def test_interface_complex(): assert 0 def test_event_simple(): assert 0 def test_something_else(): assert 0 We want to dynamically define two markers and can do it in a ``conftest.py`` plugin:: # content of conftest.py import pytest def pytest_collection_modifyitems(items): for item in items: if "interface" in item.nodeid: item.add_marker(pytest.mark.interface) elif "event" in item.nodeid: item.add_marker(pytest.mark.event) We can now use the ``-m option`` to select one set:: $ py.test -m interface --tb=short ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_module.py FF ======= FAILURES ======== _______ test_interface_simple ________ test_module.py:3: in test_interface_simple assert 0 E assert 0 _______ test_interface_complex ________ test_module.py:6: in test_interface_complex assert 0 E assert 0 ======= 2 tests deselected by "-m 'interface'" ======== ======= 2 failed, 2 deselected in 0.12 seconds ======== or to select both "event" and "interface" tests:: $ py.test -m "interface or event" --tb=short ======= test session starts ======== platform linux -- Python 3.4.3, pytest-2.8.7, py-1.4.31, pluggy-0.3.1 rootdir: $REGENDOC_TMPDIR, inifile: collected 4 items test_module.py FFF ======= FAILURES ======== _______ test_interface_simple ________ test_module.py:3: in test_interface_simple assert 0 E assert 0 _______ test_interface_complex ________ test_module.py:6: in test_interface_complex assert 0 E assert 0 _______ test_event_simple ________ test_module.py:9: in test_event_simple assert 0 E assert 0 ======= 1 tests deselected by "-m 'interface or event'" ======== ======= 3 failed, 1 deselected in 0.12 seconds ======== pytest-2.8.7/doc/en/example/index.rst0000664000175000017500000000170012651247335020067 0ustar ronnyronny00000000000000 .. _examples: Usages and Examples =========================================== Here is a (growing) list of examples. :ref:`Contact ` us if you need more examples or have questions. Also take a look at the :ref:`comprehensive documentation ` which contains many example snippets as well. Also, `pytest on stackoverflow.com `_ often comes with example answers. For basic examples, see - :doc:`../getting-started` for basic introductory examples - :ref:`assert` for basic assertion examples - :ref:`fixtures` for basic fixture/setup examples - :ref:`parametrize` for basic test function parametrization - :doc:`../unittest` for basic unittest integration - :doc:`../nose` for basic nosetests integration The following examples aim at various use cases you might encounter. .. toctree:: :maxdepth: 2 reportingdemo simple parametrize markers special pythoncollection nonpython pytest-2.8.7/doc/en/example/conftest.py0000664000175000017500000000003712651247335020427 0ustar ronnyronny00000000000000collect_ignore = ["nonpython"] pytest-2.8.7/doc/en/example/attic.rst0000664000175000017500000000516012651247335020070 0ustar ronnyronny00000000000000 .. _`accept example`: example: specifying and selecting acceptance tests -------------------------------------------------------------- .. sourcecode:: python # ./conftest.py def pytest_option(parser): group = parser.getgroup("myproject") group.addoption("-A", dest="acceptance", action="store_true", help="run (slow) acceptance tests") def pytest_funcarg__accept(request): return AcceptFixture(request) class AcceptFixture: def __init__(self, request): if not request.config.option.acceptance: pytest.skip("specify -A to run acceptance tests") self.tmpdir = request.config.mktemp(request.function.__name__, numbered=True) def run(self, cmd): """ called by test code to execute an acceptance test.

Otherwise you can start to add convenience and test support methods to your AcceptFixture and drive running of tools or applications and provide ways to do assertions about the output. .. _`decorate a funcarg`: example: decorating a funcarg in a test module -------------------------------------------------------------- For larger scale setups it's sometimes useful to decorate a funcarg just for a particular test module. We can extend the `accept example`_ by putting this in our test module: .. sourcecode:: python def pytest_funcarg__accept(request): # call the next factory (living in our conftest.py) arg = request.getfuncargvalue("accept") # create a special layout in our tempdir arg.tmpdir.mkdir("special") return arg class TestSpecialAcceptance: def test_sometest(self, accept): assert accept.tmpdir.join("special").check() Our module level factory will be invoked first and it can ask its request object to call the next factory and then decorate its result. This mechanism allows us to stay ignorant of how/where the function argument is provided - in our example from a `conftest plugin`_. sidenote: the temporary directory used here are instances of the `py.path.local`_ class which provides many of the os.path methods in a convenient way. .. _`py.path.local`: ../path.html#local .. _`conftest plugin`: customize.html#conftestplugin pytest-2.8.7/doc/en/example/py2py3/0000775000175000017500000000000012651247336017377 5ustar ronnyronny00000000000000pytest-2.8.7/doc/en/example/py2py3/test_py3.py0000664000175000017500000000014412651247335021521 0ustar ronnyronny00000000000000 def test_exception_syntax(): try: 0/0 except ZeroDivisionError as e: pass pytest-2.8.7/doc/en/example/py2py3/test_py2.py0000664000175000017500000000014212651247335021516 0ustar ronnyronny00000000000000 def test_exception_syntax(): try: 0/0 except ZeroDivisionError, e: pass pytest-2.8.7/doc/en/example/py2py3/conftest.py0000664000175000017500000000050412651247335021574 0ustar ronnyronny00000000000000import sys import pytest py3 = sys.version_info[0] >= 3 class DummyCollector(pytest.collect.File): def collect(self): return [] def pytest_pycollect_makemodule(path, parent): bn = path.basename if "py3" in bn and not py3 or ("py2" in bn and py3): return DummyCollector(path, parent=parent) pytest-2.8.7/doc/en/example/nonpython/0000775000175000017500000000000012651247336020265 5ustar ronnyronny00000000000000pytest-2.8.7/doc/en/example/nonpython/test_simple.yml0000664000175000017500000000011612651247335023335 0ustar ronnyronny00000000000000# test_simple.yml ok: sub1: sub1 hello: world: world some: other pytest-2.8.7/doc/en/example/nonpython/conftest.py0000664000175000017500000000247112651247335022467 0ustar ronnyronny00000000000000# content of conftest.py import pytest def pytest_collect_file(parent, path): if path.ext == ".yml" and path.basename.startswith("test"): return YamlFile(path, parent) class YamlFile(pytest.File): def collect(self): import yaml # we need a yaml parser, e.g. PyYAML raw = yaml.safe_load(self.fspath.open()) for name, spec in raw.items(): yield YamlItem(name, self, spec) class YamlItem(pytest.Item): def __init__(self, name, parent, spec): super(YamlItem, self).__init__(name, parent) self.spec = spec def runtest(self): for name, value in self.spec.items(): # some custom test execution (dumb example follows) if name != value: raise YamlException(self, name, value) def repr_failure(self, excinfo): """ called when self.runtest() raises an exception.

Thanks Carl Meyer for the report and test case. - fix issue553: properly handling inspect.getsourcelines failures in FixtureLookupError which would lead to to an internal error, obfuscating the original problem. Thanks talljosh for initial diagnose/patch and Bruno Oliveira for final patch. - fix issue660: properly report scope-mismatch-access errors independently from ordering of fixture arguments. Also avoid the pytest internal traceback which does not provide information to the user. Thanks Holger Krekel. - streamlined and documented release process. Also all versions (in setup.py and documentation generation) are now read from _pytest/__init__.py. Thanks Holger Krekel. - fixed docs to remove the notion that yield-fixtures are experimental. They are here to stay :) Thanks Bruno Oliveira. - Support building wheels by using environment markers for the requirements. Thanks Ionel Maries Cristian. - fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing when tests raised SystemExit. Thanks Holger Krekel. - reintroduced _pytest fixture of the pytester plugin which is used at least by pytest-xdist. pytest-2.8.7/doc/en/announce/release-2.7.0.rst0000664000175000017500000000737712651247335021235 0ustar ronnyronny00000000000000pytest-2.7.0: fixes, features, speed improvements =========================================================================== pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. This release is supposed to be drop-in compatible to 2.6.X.

Thanks Daniel Hahler. - fix issue616: conftest.py files and their contained fixutres are now properly considered for visibility, independently from the exact current working directory and test arguments that are used. Many thanks to Eric Siegerman and his PR235 which contains systematic tests for conftest visibility and now passes. This change also introduces the concept of a ``rootdir`` which is printed as a new pytest header and documented in the pytest customize web page. - change reporting of "diverted" tests, i.e. tests that are collected in one file but actually come from another (e.g. when tests in a test class come from a base class in a different file). We now show the nodeid and indicate via a postfix the other file. - add ability to set command line options by environment variable PYTEST_ADDOPTS. - added documentation on the new pytest-dev teams on bitbucket and github. See https://pytest.org/latest/contributing.html . Thanks to Anatoly for pushing and initial work on this. - fix issue650: new option ``--docttest-ignore-import-errors`` which will turn import errors in doctests into skips. Thanks Charles Cloud for the complete PR. - fix issue655: work around different ways that cause python2/3 to leak sys.exc_info into fixtures/tests causing failures in 3rd party code - fix issue615: assertion re-writing did not correctly escape % signs when formatting boolean operations, which tripped over mixing booleans with modulo operators. Thanks to Tom Viner for the report, triaging and fix. - implement issue351: add ability to specify parametrize ids as a callable to generate custom test ids. Thanks Brianna Laugher for the idea and implementation. - introduce and document new hookwrapper mechanism useful for plugins which want to wrap the execution of certain hooks for their purposes. This supersedes the undocumented ``__multicall__`` protocol which pytest itself and some external plugins use. Note that pytest-2.8 is scheduled to drop supporting the old ``__multicall__`` and only support the hookwrapper protocol. - majorly speed up invocation of plugin hooks - use hookwrapper mechanism in builtin pytest plugins. - add a doctest ini option for doctest flags, thanks Holger Peters. - add note to docs that if you want to mark a parameter and the parameter is a callable, you also need to pass in a reason to disambiguate it from the "decorator" case. Thanks Tom Viner. - "python_classes" and "python_functions" options now support glob-patterns for test discovery, as discussed in issue600. Thanks Ldiary Translations. - allow to override parametrized fixtures with non-parametrized ones and vice versa (bubenkoff). - fix issue463: raise specific error for 'parameterize' misspelling (pfctdayelise). - On failure, the ``sys.last_value``, ``sys.last_type`` and ``sys.last_traceback`` are set, so that a user can inspect the error via postmortem debugging (almarklein). pytest-2.8.7/doc/en/announce/release-2.6.3.rst0000664000175000017500000000321612651247335021223 0ustar ronnyronny00000000000000pytest-2.6.3: fixes and little improvements =========================================================================== pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms.

Check for precise "maximum recursion depth exceed" exception instead of presuming any RuntimeError is that one (implemented in py dep). Thanks Charles Cloud for analysing the issue. - fix conftest related fixture visibility issue: when running with a CWD outside a test package pytest would get fixture discovery wrong. Thanks to Wolfgang Schnerring for figuring out a reproducable example. - Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the timeout when interactively entering pdb). Thanks Wolfgang Schnerring. - check xfail/skip also with non-python function test items. Thanks Floris Bruynooghe. pytest-2.8.7/doc/en/announce/release-2.6.2.rst0000664000175000017500000000277712651247335021235 0ustar ronnyronny00000000000000pytest-2.6.2: few fixes and cx_freeze support =========================================================================== pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. This release is drop-in compatible to 2.5.2 and 2.6.X. It also brings support for including pytest with cx_freeze or similar freezing tools into your single-file app distribution. For details see the CHANGELOG below. See docs at: http://pytest.org As usual, you can upgrade from pypi via:: pip install -U pytest Thanks to all who contributed, among them: Floris Bruynooghe Benjamin Peterson Bruno Oliveira have fun, holger krekel 2.6.2 ----------- - Added function pytest.freeze_includes(), which makes it easy to embed pytest into executables using tools like cx_freeze. See docs for examples and rationale. Thanks Bruno Oliveira. - Improve assertion rewriting cache invalidation precision. - fixed issue561: adapt autouse fixture example for python3. - fixed issue453: assertion rewriting issue with __repr__ containing "\n{", "\n}" and "\n~". - fix issue560: correctly display code if an "else:" or "finally:" is followed by statements on the same line. - Fix example in monkeypatch documentation, thanks t-8ch. - fix issue572: correct tmpdir doc example for python3. - Do not mark as universal wheel because Python 2.6 is different from other builds due to the extra argparse dependency. Fixes issue566.

The 2.6.1 release is drop-in compatible to 2.5.2 and actually fixes some regressions introduced with 2.6.0. It also brings a little feature to the xfail marker which now recognizes expected exceptions, see the CHANGELOG below. See docs at: http://pytest.org As usual, you can upgrade from pypi via:: pip install -U pytest Thanks to all who contributed, among them: Floris Bruynooghe Bruno Oliveira Nicolas Delaby have fun, holger krekel Changes 2.6.1 ================= - No longer show line numbers in the --verbose output, the output is now purely the nodeid. The line number is still shown in failure reports. Thanks Floris Bruynooghe. - fix issue437 where assertion rewriting could cause pytest-xdist slaves to collect different tests. Thanks Bruno Oliveira. - fix issue555: add "errors" attribute to capture-streams to satisfy some distutils and possibly other code accessing sys.stdout.errors. - fix issue547 capsys/capfd also work when output capturing ("-s") is disabled. - address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via an optional "raises=EXC" argument where EXC can be a single exception or a tuple of exception classes. Thanks David Mohr for the complete PR. - fix integration of pytest with unittest.mock.patch decorator when it uses the "new" argument. Thanks Nicolas Delaby for test and PR. - fix issue with detecting conftest files if the arguments contain "::" node id specifications (copy pasted from "-v" output) - fix issue544 by only removing "@NUM" at the end of "::" separated parts and if the part has an ".py" extension - don't use py.std import helper, rather import things directly. Thanks Bruno Oliveira. pytest-2.8.7/doc/en/announce/release-2.6.0.rst0000664000175000017500000001327112651247335021222 0ustar ronnyronny00000000000000pytest-2.6.0: shorter tracebacks, new warning system, test runner compat =========================================================================== pytest is a mature Python testing tool with more than a 1000 tests against itself, passing on many different interpreters and platforms. The 2.6.0 release should be drop-in backward compatible to 2.5.2 and fixes a number of bugs and brings some new features, mainly: - shorter tracebacks by default: only the first (test function) entry and the last (failure location) entry are shown, the ones between only in "short" format. Use ``--tb=long`` to get back the old behaviour of showing "long" entries everywhere. - a new warning system which reports oddities during collection and execution. For example, ignoring collecting Test* classes with an ``__init__`` now produces a warning. - various improvements to nose/mock/unittest integration Note also that 2.6.0 departs with the "zero reported bugs" policy because it has been too hard to keep up with it, unfortunately. Instead we are for now rather bound to work on "upvoted" issues in the https://bitbucket.org/pytest-dev/pytest/issues?status=new&status=open&sort=-votes issue tracker. See docs at: http://pytest.org As usual, you can upgrade from pypi via:: pip install -U pytest Thanks to all who contributed, among them: Benjamin Peterson Jurko Gospodnetić Floris Bruynooghe Marc Abramowitz Marc Schlaich Trevor Bekolay Bruno Oliveira Alex Groenholm have fun, holger krekel 2.6.0 ----------------------------------- - fix issue537: Avoid importing old assertion reinterpretation code by default. Thanks Benjamin Peterson. - fix issue364: shorten and enhance tracebacks representation by default. The new "--tb=auto" option (default) will only display long tracebacks for the first and last entry. You can get the old behaviour of printing all entries as long entries with "--tb=long". Also short entries by default are now printed very similarly to "--tb=native" ones. - fix issue514: teach assertion reinterpretation about private class attributes Thanks Benjamin Peterson. - change -v output to include full node IDs of tests. Users can copy a node ID from a test run, including line number, and use it as a positional argument in order to run only a single test. - fix issue 475: fail early and comprehensible if calling pytest.raises with wrong exception type. - fix issue516: tell in getting-started about current dependencies. - cleanup setup.py a bit and specify supported versions. Thanks Jurko Gospodnetic for the PR. - change XPASS colour to yellow rather then red when tests are run with -v. - fix issue473: work around mock putting an unbound method into a class dict when double-patching. - fix issue498: if a fixture finalizer fails, make sure that the fixture is still invalidated. - fix issue453: the result of the pytest_assertrepr_compare hook now gets it's newlines escaped so that format_exception does not blow up. - internal new warning system: pytest will now produce warnings when it detects oddities in your test collection or execution. Warnings are ultimately sent to a new pytest_logwarning hook which is currently only implemented by the terminal plugin which displays warnings in the summary line and shows more details when -rw (report on warnings) is specified. - change skips into warnings for test classes with an __init__ and callables in test modules which look like a test but are not functions. - fix issue436: improved finding of initial conftest files from command line arguments by using the result of parse_known_args rather than the previous flaky heuristics. Thanks Marc Abramowitz for tests and initial fixing approaches in this area. - fix issue #479: properly handle nose/unittest(2) SkipTest exceptions during collection/loading of test modules. Thanks to Marc Schlaich for the complete PR. - fix issue490: include pytest_load_initial_conftests in documentation and improve docstring. - fix issue472: clarify that ``pytest.config.getvalue()`` cannot work if it's triggered ahead of command line parsing. - merge PR123: improved integration with mock.patch decorator on tests. - fix issue412: messing with stdout/stderr FD-level streams is now captured without crashes. - fix issue483: trial/py33 works now properly. Thanks Daniel Grana for PR. - improve example for pytest integration with "python setup.py test" which now has a generic "-a" or "--pytest-args" option where you can pass additional options as a quoted string. Thanks Trevor Bekolay. - simplified internal capturing mechanism and made it more robust against tests or setups changing FD1/FD2, also better integrated now with pytest.pdb() in single tests. - improvements to pytest's own test-suite leakage detection, courtesy of PRs from Marc Abramowitz - fix issue492: avoid leak in test_writeorg. Thanks Marc Abramowitz. - fix issue493: don't run tests in doc directory with ``python setup.py test`` (use tox -e doctesting for that) - fix issue486: better reporting and handling of early conftest loading failures - some cleanup and simplification of internal conftest handling. - work a bit harder to break reference cycles when catching exceptions. Thanks Jurko Gospodnetic. - fix issue443: fix skip examples to use proper comparison. Thanks Alex Groenholm. - support nose-style ``__test__`` attribute on modules, classes and functions, including unittest-style Classes. If set to False, the test will not be collected. - fix issue512: show "" for arguments which might not be set in monkeypatch plugin. Improves output in documentation. - avoid importing "py.test" (an old alias module for "pytest") pytest-2.8.7/doc/en/announce/release-2.5.2.rst0000664000175000017500000000361112651247335021220 0ustar ronnyronny00000000000000pytest-2.5.2: fixes =========================================================================== pytest is a mature Python testing tool with more than a 1000 tests against itself, passing on many different interpreters and platforms. The 2.5.2 release fixes a few bugs with two maybe-bugs remaining and actively being worked on (and waiting for the bug reporter's input). We also have a new contribution guide thanks to Piotr Banaszkiewicz and others. See docs at: http://pytest.org As usual, you can upgrade from pypi via:: pip install -U pytest Thanks to the following people who contributed to this release: Anatoly Bubenkov Ronny Pfannschmidt Floris Bruynooghe Bruno Oliveira Andreas Pelme Jurko Gospodnetić Piotr Banaszkiewicz Simon Liedtke lakka Lukasz Balcerzak Philippe Muller Daniel Hahler have fun, holger krekel 2.5.2 ----------------------------------- - fix issue409 -- better interoperate with cx_freeze by not trying to import from collections.abc which causes problems for py27/cx_freeze. Thanks Wolfgang L. for reporting and tracking it down. - fixed docs and code to use "pytest" instead of "py.test" almost everywhere. Thanks Jurko Gospodnetic for the complete PR. - fix issue425: mention at end of "py.test -h" that --markers and --fixtures work according to specified test path (or current dir) - fix issue413: exceptions with unicode attributes are now printed correctly also on python2 and with pytest-xdist runs. (the fix requires py-1.4.20) - copy, cleanup and integrate py.io capture from pylib 1.4.20.dev2 (rev 13d9af95547e) - address issue416: clarify docs as to conftest.py loading semantics - fix issue429: comparing byte strings with non-ascii chars in assert expressions now work better.

The 2.5.1 release maintains the "zero-reported-bugs" promise by fixing the three bugs reported since the last release a few days ago. It also features a new home page styling implemented by Tobias Bieniek, based on the flask theme from Armin Ronacher: http://pytest.org If you have anything more to improve styling and docs, we'd be very happy to merge further pull requests. On the coding side, the release also contains a little enhancement to fixture decorators allowing to directly influence generation of test ids, thanks to Floris Bruynooghe. Other thanks for helping with this release go to Anatoly Bubenkoff and Ronny Pfannschmidt. As usual, you can upgrade from pypi via:: pip install -U pytest have fun and a nice remaining "bug-free" time of the year :) holger krekel 2.5.1 ----------------------------------- - merge new documentation styling PR from Tobias Bieniek. - fix issue403: allow parametrize of multiple same-name functions within a collection node. Thanks Andreas Kloeckner and Alex Gaynor for reporting and analysis. - Allow parameterized fixtures to specify the ID of the parameters by adding an ids argument to pytest.fixture() and pytest.yield_fixture(). Thanks Floris Bruynooghe. - fix issue404 by always using the binary xml escape in the junitxml plugin. Thanks Ronny Pfannschmidt. - fix issue407: fix addoption docstring to point to argparse instead of optparse. Thanks Daniel D. Wright. pytest-2.8.7/doc/en/announce/release-2.5.0.rst0000664000175000017500000001621412651247335021221 0ustar ronnyronny00000000000000pytest-2.5.0: now down to ZERO reported bugs! =========================================================================== pytest-2.5.0 is a big fixing release, the result of two community bug fixing days plus numerous additional works from many people and reporters. The release should be fully compatible to 2.4.2, existing plugins and test suites. We aim at maintaining this level of ZERO reported bugs because it's no fun if your testing tool has bugs, is it? Under a condition, though: when submitting a bug report please provide clear information about the circumstances and a simple example which reproduces the problem. The issue tracker is of course not empty now. We have many remaining "enhacement" issues which we'll hopefully can tackle in 2014 with your help. For those who use older Python versions, please note that pytest is not automatically tested on python2.5 due to virtualenv, setuptools and tox not supporting it anymore. Manual verification shows that it mostly works fine but it's not going to be part of the automated release process and thus likely to break in the future. As usual, current docs are at http://pytest.org and you can upgrade from pypi via:: pip install -U pytest Particular thanks for helping with this release go to Anatoly Bubenkoff, Floris Bruynooghe, Marc Abramowitz, Ralph Schmitt, Ronny Pfannschmidt, Donald Stufft, James Lan, Rob Dennis, Jason R. Coombs, Mathieu Agopian, Virgil Dupras, Bruno Oliveira, Alex Gaynor and others. have fun, holger krekel 2.5.0 ----------------------------------- - dropped python2.5 from automated release testing of pytest itself which means it's probably going to break soon (but still works with this release we believe). - simplified and fixed implementation for calling finalizers when parametrized fixtures or function arguments are involved. finalization is now performed lazily at setup time instead of in the "teardown phase". While this might sound odd at first, it helps to ensure that we are correctly handling setup/teardown even in complex code. User-level code should not be affected unless it's implementing the pytest_runtest_teardown hook and expecting certain fixture instances are torn down within (very unlikely and would have been unreliable anyway). - PR90: add --color=yes|no|auto option to force terminal coloring mode ("auto" is default). Thanks Marc Abramowitz. - fix issue319 - correctly show unicode in assertion errors. Many thanks to Floris Bruynooghe for the complete PR. Also means we depend on py>=1.4.19 now. - fix issue396 - correctly sort and finalize class-scoped parametrized tests independently from number of methods on the class. - refix issue323 in a better way -- parametrization should now never cause Runtime Recursion errors because the underlying algorithm for re-ordering tests per-scope/per-fixture is not recursive anymore (it was tail-call recursive before which could lead to problems for more than >966 non-function scoped parameters). - fix issue290 - there is preliminary support now for parametrizing with repeated same values (sometimes useful to to test if calling a second time works as with the first time). - close issue240 - document precisely how pytest module importing works, discuss the two common test directory layouts, and how it interacts with PEP420-namespace packages. - fix issue246 fix finalizer order to be LIFO on independent fixtures depending on a parametrized higher-than-function scoped fixture. (was quite some effort so please bear with the complexity of this sentence :) Thanks Ralph Schmitt for the precise failure example. - fix issue244 by implementing special index for parameters to only use indices for paramentrized test ids - fix issue287 by running all finalizers but saving the exception from the first failing finalizer and re-raising it so teardown will still have failed. We reraise the first failing exception because it might be the cause for other finalizers to fail. - fix ordering when mock.patch or other standard decorator-wrappings are used with test methods. This fixues issue346 and should help with random "xdist" collection failures. Thanks to Ronny Pfannschmidt and Donald Stufft for helping to isolate it. - fix issue357 - special case "-k" expressions to allow for filtering with simple strings that are not valid python expressions. Examples: "-k 1.3" matches all tests parametrized with 1.3. "-k None" filters all tests that have "None" in their name and conversely "-k 'not None'". Previously these examples would raise syntax errors. - fix issue384 by removing the trial support code since the unittest compat enhancements allow trial to handle it on its own - don't hide an ImportError when importing a plugin produces one. fixes issue375. - fix issue275 - allow usefixtures and autouse fixtures for running doctest text files. - fix issue380 by making --resultlog only rely on longrepr instead of the "reprcrash" attribute which only exists sometimes. - address issue122: allow @pytest.fixture(params=iterator) by exploding into a list early on. - fix pexpect-3.0 compatibility for pytest's own tests. (fixes issue386) - allow nested parametrize-value markers, thanks James Lan for the PR. - fix unicode handling with new monkeypatch.setattr(import_path, value) API. Thanks Rob Dennis. Fixes issue371. - fix unicode handling with junitxml, fixes issue368. - In assertion rewriting mode on Python 2, fix the detection of coding cookies. See issue #330. - make "--runxfail" turn imperative pytest.xfail calls into no ops (it already did neutralize pytest.mark.xfail markers) - refine pytest / pkg_resources interactions: The AssertionRewritingHook PEP302 compliant loader now registers itself with setuptools/pkg_resources properly so that the pkg_resources.resource_stream method works properly. Fixes issue366. Thanks for the investigations and full PR to Jason R. Coombs. - pytestconfig fixture is now session-scoped as it is the same object during the whole test run. Fixes issue370. - avoid one surprising case of marker malfunction/confusion:: @pytest.mark.some(lambda arg: ...) def test_function(): would not work correctly because pytest assumes @pytest.mark.some gets a function to be decorated already. We now at least detect if this arg is an lambda and thus the example will work. Thanks Alex Gaynor for bringing it up. - xfail a test on pypy that checks wrong encoding/ascii (pypy does not error out). fixes issue385. - internally make varnames() deal with classes's __init__, although it's not needed by pytest itself atm. Also fix caching. Fixes issue376. - fix issue221 - handle importing of namespace-package with no __init__.py properly. - refactor internal FixtureRequest handling to avoid monkeypatching. One of the positive user-facing effects is that the "request" object can now be used in closures. - fixed version comparison in pytest.importskip(modname, minverstring) - fix issue377 by clarifying in the nose-compat docs that pytest does not duplicate the unittest-API into the "plain" namespace. - fix verbose reporting for @mock'd test functions pytest-2.8.7/doc/en/announce/release-2.4.2.rst0000664000175000017500000000262612651247335021224 0ustar ronnyronny00000000000000pytest-2.4.2: colorama on windows, plugin/tmpdir fixes =========================================================================== pytest-2.4.2 is another bug-fixing release: - on Windows require colorama and a newer py lib so that py.io.TerminalWriter() now uses colorama instead of its own ctypes hacks. (fixes issue365) thanks Paul Moore for bringing it up. - fix "-k" matching of tests where "repr" and "attr" and other names would cause wrong matches because of an internal implementation quirk (don't ask) which is now properly implemented. fixes issue345. - avoid tmpdir fixture to create too long filenames especially when parametrization is used (issue354) - fix pytest-pep8 and pytest-flakes / pytest interactions (collection names in mark plugin was assuming an item always has a function which is not true for those plugins etc.) Thanks Andi Zeidler. - introduce node.get_marker/node.add_marker API for plugins like pytest-pep8 and pytest-flakes to avoid the messy details of the node.keywords pseudo-dicts. Adapted docs. - remove attempt to "dup" stdout at startup as it's icky. the normal capturing should catch enough possibilities of tests messing up standard FDs. - add pluginmanager.do_configure(config) as a link to config.do_configure() for plugin-compatibility as usual, docs at http://pytest.org and upgrades via:: pip install -U pytest have fun, holger krekel pytest-2.8.7/doc/en/announce/release-2.4.1.rst0000664000175000017500000000156212651247335021221 0ustar ronnyronny00000000000000pytest-2.4.1: fixing three regressions compared to 2.3.5 =========================================================================== pytest-2.4.1 is a quick follow up release to fix three regressions compared to 2.3.5 before they hit more people: - When using parser.addoption() unicode arguments to the "type" keyword should also be converted to the respective types. thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362) - fix dotted filename completion when using argcomplete thanks Anthon van der Neuth. (fixes issue361) - fix regression when a 1-tuple ("arg",) is used for specifying parametrization (the values of the parametrization were passed nested in a tuple).

See below for a full list of details. A few feature highlights: - new yield-style fixtures `pytest.yield_fixture `_, allowing to use existing with-style context managers in fixture functions. - improved pdb support: ``import pdb ; pdb.set_trace()`` now works without requiring prior disabling of stdout/stderr capturing. Also the ``--pdb`` options works now on collection and internal errors and we introduced a new experimental hook for IDEs/plugins to intercept debugging: ``pytest_exception_interact(node, call, report)``. - shorter monkeypatch variant to allow specifying an import path as a target, for example: ``monkeypatch.setattr("requests.get", myfunc)`` - better unittest/nose compatibility: all teardown methods are now only called if the corresponding setup method succeeded. - integrate tab-completion on command line options if you have `argcomplete `_ configured. - allow boolean expression directly with skipif/xfail if a "reason" is also specified. - a new hook ``pytest_load_initial_conftests`` allows plugins like `pytest-django `_ to influence the environment before conftest files import ``django``. - reporting: color the last line red or green depending if failures/errors occurred or everything passed. The documentation has been updated to accomodate the changes, see `http://pytest.org `_ To install or upgrade pytest:: pip install -U pytest # or easy_install -U pytest **Many thanks to all who helped, including Floris Bruynooghe, Brianna Laugher, Andreas Pelme, Anthon van der Neut, Anatoly Bubenkoff, Vladimir Keleshev, Mathieu Agopian, Ronny Pfannschmidt, Christian Theunert and many others.** may passing tests be with you, holger krekel Changes between 2.3.5 and 2.4 ----------------------------------- known incompatibilities: - if calling --genscript from python2.7 or above, you only get a standalone script which works on python2.7 or above. Use Python2.6 to also get a python2.5 compatible version. - all xunit-style teardown methods (nose-style, pytest-style, unittest-style) will not be called if the corresponding setup method failed, see issue322 below. - the pytest_plugin_unregister hook wasn't ever properly called and there is no known implementation of the hook - so it got removed. - pytest.fixture-decorated functions cannot be generators (i.e. use yield) anymore. This change might be reversed in 2.4.1 if it causes unforeseen real-life issues. However, you can always write and return an inner function/generator and change the fixture consumer to iterate over the returned generator. This change was done in lieu of the new ``pytest.yield_fixture`` decorator, see below. new features: - experimentally introduce a new ``pytest.yield_fixture`` decorator which accepts exactly the same parameters as pytest.fixture but mandates a ``yield`` statement instead of a ``return statement`` from fixture functions. This allows direct integration with "with-style" context managers in fixture functions and generally avoids registering of finalization callbacks in favour of treating the "after-yield" as teardown code. Thanks Andreas Pelme, Vladimir Keleshev, Floris Bruynooghe, Ronny Pfannschmidt and many others for discussions. - allow boolean expression directly with skipif/xfail if a "reason" is also specified. Rework skipping documentation to recommend "condition as booleans" because it prevents surprises when importing markers between modules. Specifying conditions as strings will remain fully supported. - reporting: color the last line red or green depending if failures/errors occurred or everything passed. thanks Christian Theunert. - make "import pdb ; pdb.set_trace()" work natively wrt capturing (no "-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut. - fix issue181: --pdb now also works on collect errors (and on internal errors) . This was implemented by a slight internal refactoring and the introduction of a new hook ``pytest_exception_interact`` hook (see next item). - fix issue341: introduce new experimental hook for IDEs/terminals to intercept debugging: ``pytest_exception_interact(node, call, report)``. - new monkeypatch.setattr() variant to provide a shorter invocation for patching out classes/functions from modules: monkeypatch.setattr("requests.get", myfunc) will replace the "get" function of the "requests" module with ``myfunc``. - fix issue322: tearDownClass is not run if setUpClass failed. Thanks Mathieu Agopian for the initial fix. Also make all of pytest/nose finalizer mimick the same generic behaviour: if a setupX exists and fails, don't run teardownX. This internally introduces a new method "node.addfinalizer()" helper which can only be called during the setup phase of a node. - simplify pytest.mark.parametrize() signature: allow to pass a CSV-separated string to specify argnames. For example: ``pytest.mark.parametrize("input,expected", [(1,2), (2,3)])`` works as well as the previous: ``pytest.mark.parametrize(("input", "expected"), ...)``. - add support for setUpModule/tearDownModule detection, thanks Brian Okken. - integrate tab-completion on options through use of "argcomplete". Thanks Anthon van der Neut for the PR. - change option names to be hyphen-separated long options but keep the old spelling backward compatible. py.test -h will only show the hyphenated version, for example "--collect-only" but "--collectonly" will remain valid as well (for backward-compat reasons). Many thanks to Anthon van der Neut for the implementation and to Hynek Schlawack for pushing us. - fix issue 308 - allow to mark/xfail/skip individual parameter sets when parametrizing. Thanks Brianna Laugher. - call new experimental pytest_load_initial_conftests hook to allow 3rd party plugins to do something before a conftest is loaded. Bug fixes: - fix issue358 - capturing options are now parsed more properly by using a new parser.parse_known_args method. - pytest now uses argparse instead of optparse (thanks Anthon) which means that "argparse" is added as a dependency if installing into python2.6 environments or below. - fix issue333: fix a case of bad unittest/pytest hook interaction. - PR27: correctly handle nose.SkipTest during collection. Thanks Antonio Cuni, Ronny Pfannschmidt. - fix issue355: junitxml puts name="pytest" attribute to testsuite tag. - fix issue336: autouse fixture in plugins should work again. - fix issue279: improve object comparisons on assertion failure for standard datatypes and recognise collections.abc. Thanks to Brianna Laugher and Mathieu Agopian. - fix issue317: assertion rewriter support for the is_package method - fix issue335: document py.code.ExceptionInfo() object returned from pytest.raises(), thanks Mathieu Agopian. - remove implicit distribute_setup support from setup.py. - fix issue305: ignore any problems when writing pyc files. - SO-17664702: call fixture finalizers even if the fixture function partially failed (finalizers would not always be called before) - fix issue320 - fix class scope for fixtures when mixed with module-level functions. Thanks Anatloy Bubenkoff. - you can specify "-q" or "-qq" to get different levels of "quieter" reporting (thanks Katarzyna Jachim) - fix issue300 - Fix order of conftest loading when starting py.test in a subdirectory. - fix issue323 - sorting of many module-scoped arg parametrizations - make sessionfinish hooks execute with the same cwd-context as at session start (helps fix plugin behaviour which write output files with relative path such as pytest-cov) - fix issue316 - properly reference collection hooks in docs - fix issue 306 - cleanup of -k/-m options to only match markers/test names/keywords respectively. Thanks Wouter van Ackooy. - improved doctest counting for doctests in python modules -- files without any doctest items will not show up anymore and doctest examples are counted as separate test items. thanks Danilo Bellini. - fix issue245 by depending on the released py-1.4.14 which fixes py.io.dupfile to work with files with no mode. Thanks Jason R. Coombs. - fix junitxml generation when test output contains control characters, addressing issue267, thanks Jaap Broekhuizen - fix issue338: honor --tb style for setup/teardown errors as well. Thanks Maho. - fix issue307 - use yaml.safe_load in example, thanks Mark Eichin. - better parametrize error messages, thanks Brianna Laugher - pytest_terminal_summary(terminalreporter) hooks can now use ".section(title)" and ".line(msg)" methods to print extra information at the end of a test run. pytest-2.8.7/doc/en/announce/release-2.3.5.rst0000664000175000017500000000635312651247335021227 0ustar ronnyronny00000000000000pytest-2.3.5: bug fixes and little improvements =========================================================================== pytest-2.3.5 is a maintenance release with many bug fixes and little improvements. See the changelog below for details. No backward compatibility issues are foreseen and all plugins which worked with the prior version are expected to work unmodified. Speaking of which, a few interesting new plugins saw the light last month: - pytest-instafail: show failure information while tests are running - pytest-qt: testing of GUI applications written with QT/Pyside - pytest-xprocess: managing external processes across test runs - pytest-random: randomize test ordering And several others like pytest-django saw maintenance releases.

This release comes with the following fixes and features: - make "-k" option accept an expressions the same as with "-m" so that one can write: -k "name1 or name2" etc. This is a slight usage incompatibility if you used special syntax like "TestClass.test_method" which you now need to write as -k "TestClass and test_method" to match a certain method in a certain test class. - allow to dynamically define markers via item.keywords[...]=assignment integrating with "-m" option - yielded test functions will now have autouse-fixtures active but cannot accept fixtures as funcargs - it's anyway recommended to rather use the post-2.0 parametrize features instead of yield, see: http://pytest.org/latest/example/parametrize.html - fix autouse-issue where autouse-fixtures would not be discovered if defined in a a/conftest.py file and tests in a/tests/test_some.py - fix issue226 - LIFO ordering for fixture teardowns - fix issue224 - invocations with >256 char arguments now work - fix issue91 - add/discuss package/directory level setups in example - fixes related to autouse discovery and calling Thanks in particular to Thomas Waldmann for spotting and reporting issues.

It is now easier, more efficient and more predicatable to re-run the same tests with different fixture instances. Also, you can directly declare the caching "scope" of fixtures so that dependent tests throughout your whole test suite can re-use database or other expensive fixture objects with ease. Lastly, it's possible for fixture functions (formerly known as funcarg factories) to use other fixtures, allowing for a completely modular and re-useable fixture design. For detailed info and tutorial-style examples, see: http://pytest.org/latest/fixture.html Moreover, there is now support for using pytest fixtures/funcargs with unittest-style suites, see here for examples: http://pytest.org/latest/unittest.html Besides, more unittest-test suites are now expected to "simply work" with pytest. All changes are backward compatible and you should be able to continue to run your test suites and 3rd party plugins that worked with pytest-2.2.4. If you are interested in the precise reasoning (including examples) of the pytest-2.3 fixture evolution, please consult http://pytest.org/latest/funcarg_compare.html For general info on installation and getting started: http://pytest.org/latest/getting-started.html Docs and PDF access as usual at: http://pytest.org and more details for those already in the knowing of pytest can be found in the CHANGELOG below. Particular thanks for this release go to Floris Bruynooghe, Alex Okrushko Carl Meyer, Ronny Pfannschmidt, Benjamin Peterson and Alex Gaynor for helping to get the new features right and well integrated. Ronny and Floris also helped to fix a number of bugs and yet more people helped by providing bug reports. have fun, holger krekel Changes between 2.2.4 and 2.3.0 ----------------------------------- - fix issue202 - better automatic names for parametrized test functions - fix issue139 - introduce @pytest.fixture which allows direct scoping and parametrization of funcarg factories.

For general information see here: http://pytest.org/ To install or upgrade pytest: pip install -U pytest # or easy_install -U pytest Special thanks for helping on this release to Ronny Pfannschmidt, Jurko Gospodnetic and Ralf Schmitt. best, holger krekel Changes between 2.2.0 and 2.2.1 ---------------------------------------- - fix issue99 (in pytest and py) internallerrors with resultlog now produce better output - fixed by normalizing pytest_internalerror input arguments. - fix issue97 / traceback issues (in pytest and py) improve traceback output in conjunction with jinja2 and cython which hack tracebacks - fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns": the final test in a test node will now run its teardown directly instead of waiting for the end of the session. Thanks Dave Hunt for the good reporting and feedback. The pytest_runtest_protocol as well as the pytest_runtest_teardown hooks now have "nextitem" available which will be None indicating the end of the test run. - fix collection crash due to unknown-source collected items, thanks to Ralf Schmitt (fixed by depending on a more recent pylib) pytest-2.8.7/doc/en/announce/release-2.2.0.rst0000664000175000017500000001034712651247335021217 0ustar ronnyronny00000000000000py.test 2.2.0: test marking++, parametrization++ and duration profiling =========================================================================== pytest-2.2.0 is a test-suite compatible release of the popular py.test testing tool. Plugins might need upgrades. It comes with these improvements: * easier and more powerful parametrization of tests: - new @pytest.mark.parametrize decorator to run tests with different arguments - new metafunc.parametrize() API for parametrizing arguments independently - see examples at http://pytest.org/latest/example/parametrize.html - NOTE that parametrize() related APIs are still a bit experimental and might change in future releases. * improved handling of test markers and refined marking mechanism: - "-m markexpr" option for selecting tests according to their mark - a new "markers" ini-variable for registering test markers for your project - the new "--strict" bails out with an error if using unregistered markers. - see examples at http://pytest.org/latest/example/markers.html * duration profiling: new "--duration=N" option showing the N slowest test execution or setup/teardown calls. This is most useful if you want to find out where your slowest test code is. * also 2.2.0 performs more eager calling of teardown/finalizers functions resulting in better and more accurate reporting when they fail Besides there is the usual set of bug fixes along with a cleanup of pytest's own test suite allowing it to run on a wider range of environments. For general information, see extensive docs with examples here: http://pytest.org/ If you want to install or upgrade pytest you might just type:: pip install -U pytest # or easy_install -U pytest Thanks to Ronny Pfannschmidt, David Burns, Jeff Donner, Daniel Nouri, Alfredo Deza and all who gave feedback or sent bug reports. best, holger krekel notes on incompatibility ------------------------------ While test suites should work unchanged you might need to upgrade plugins: * You need a new version of the pytest-xdist plugin (1.7) for distributing test runs. * Other plugins might need an upgrade if they implement the ``pytest_runtest_logreport`` hook which now is called unconditionally for the setup/teardown fixture phases of a test. You may choose to ignore setup/teardown failures by inserting "if rep.when != 'call': return" or something similar. Note that most code probably "just" works because the hook was already called for failing setup/teardown phases of a test so a plugin should have been ready to grok such reports already. Changes between 2.1.3 and 2.2.0 ---------------------------------------- - fix issue90: introduce eager tearing down of test items so that teardown function are called earlier. - add an all-powerful metafunc.parametrize function which allows to parametrize test function arguments in multiple steps and therefore from independent plugins and places. - add a @pytest.mark.parametrize helper which allows to easily call a test function with different argument values. - Add examples to the "parametrize" example page, including a quick port of Test scenarios and the new parametrize function and decorator. - introduce registration for "pytest.mark.*" helpers via ini-files or through plugin hooks. Also introduce a "--strict" option which will treat unregistered markers as errors allowing to avoid typos and maintain a well described set of markers for your test suite. See examples at http://pytest.org/latest/mark.html and its links. - issue50: introduce "-m marker" option to select tests based on markers (this is a stricter and more predictable version of "-k" in that "-m" only matches complete markers and has more obvious rules for and/or semantics. - new feature to help optimizing the speed of your tests: --durations=N option for displaying N slowest test calls and setup/teardown methods. - fix issue87: --pastebin now works with python3 - fix issue89: --pdb with unexpected exceptions in doctest work more sensibly - fix and cleanup pytest's own test suite to not leak FDs - fix issue83: link to generated funcarg list - fix issue74: pyarg module names are now checked against imp.find_module false positives - fix compatibility with twisted/trial-11.1.0 use cases pytest-2.8.7/doc/en/announce/release-2.1.3.rst0000664000175000017500000000226512651247335021221 0ustar ronnyronny00000000000000py.test 2.1.3: just some more fixes =========================================================================== pytest-2.1.3 is a minor backward compatible maintenance release of the popular py.test testing tool.

See extensive docs with examples here: http://pytest.org/ Most bug fixes address remaining issues with the perfected assertions introduced with 2.1.0 - many thanks to the bug reporters and to Benjamin Peterson for helping to fix them. Also, junitxml output now produces system-out/err tags which lead to better displays of tracebacks with Jenkins.

See the improved extensive docs (now also as PDF!) with tested examples here: http://pytest.org/ The single biggest news about this release are **perfected assertions** courtesy of Benjamin Peterson. You can now safely use ``assert`` statements in test modules without having to worry about side effects or python optimization ("-OO") options. This is achieved by rewriting assert statements in test modules upon import, using a PEP302 hook. See http://pytest.org/assert.html#advanced-assertion-introspection for detailed information. The work has been partly sponsored by my company, merlinux GmbH. For further details on bug fixes and smaller enhancements see below.

See the extensive docs with tested examples here: http://pytest.org/ If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest There also is a bugfix release 1.6 of pytest-xdist, the plugin that enables seemless distributed and "looponfail" testing for Python. best, holger krekel Changes between 2.0.2 and 2.0.3 ---------------------------------------------- - fix issue38: nicer tracebacks on calls to hooks, particularly early configure/sessionstart ones - fix missing skip reason/meta information in junitxml files, reported via http://lists.idyll.org/pipermail/testing-in-python/2011-March/003928.html - fix issue34: avoid collection failure with "test" prefixed classes deriving from object. - don't require zlib (and other libs) for genscript plugin without --genscript actually being used. - speed up skips (by not doing a full traceback represenation internally) - fix issue37: avoid invalid characters in junitxml's output pytest-2.8.7/doc/en/announce/release-2.0.2.rst0000664000175000017500000000535512651247335021222 0ustar ronnyronny00000000000000py.test 2.0.2: bug fixes, improved xfail/skip expressions, speed ups =========================================================================== Welcome to pytest-2.0.2, a maintenance and bug fix release of pytest, a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See the extensive docs with tested examples here: http://pytest.org/ If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest Many thanks to all issue reporters and people asking questions or complaining, particularly Jurko for his insistence, Laura, Victor and Brianna for helping with improving and Ronny for his general advise. best, holger krekel Changes between 2.0.1 and 2.0.2 ---------------------------------------------- - tackle issue32 - speed up test runs of very quick test functions by reducing the relative overhead - fix issue30 - extended xfail/skipif handling and improved reporting. If you have a syntax error in your skip/xfail expressions you now get nice error reports. Also you can now access module globals from xfail/skipif expressions so that this for example works now:: import pytest import mymodule @pytest.mark.skipif("mymodule.__version__[0] == "1") def test_function(): pass This will not run the test function if the module's version string does not start with a "1". Note that specifying a string instead of a boolean expressions allows py.test to report meaningful information when summarizing a test run as to what conditions lead to skipping (or xfail-ing) tests. - fix issue28 - setup_method and pytest_generate_tests work together The setup_method fixture method now gets called also for test function invocations generated from the pytest_generate_tests hook. - fix issue27 - collectonly and keyword-selection (-k) now work together Also, if you do "py.test --collectonly -q" you now get a flat list of test ids that you can use to paste to the py.test commandline in order to execute a particular test. - fix issue25 avoid reported problems with --pdb and python3.2/encodings output - fix issue23 - tmpdir argument now works on Python3.2 and WindowsXP Starting with Python3.2 os.symlink may be supported. By requiring a newer py lib version the py.path.local() implementation acknowledges this. - fixed typos in the docs (thanks Victor Garcia, Brianna Laugher) and particular thanks to Laura Creighton who also revieved parts of the documentation. - fix slighly wrong output of verbose progress reporting for classes (thanks Amaury) - more precise (avoiding of) deprecation warnings for node.Class|Function accesses - avoid std unittest assertion helper code in tracebacks (thanks Ronny) pytest-2.8.7/doc/en/announce/release-2.0.1.rst0000664000175000017500000000602112651247335021210 0ustar ronnyronny00000000000000py.test 2.0.1: bug fixes =========================================================================== Welcome to pytest-2.0.1, a maintenance and bug fix release of pytest, a mature testing tool for Python, supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See extensive docs with tested examples here: http://pytest.org/ If you want to install or upgrade pytest, just type one of:: pip install -U pytest # or easy_install -U pytest Many thanks to all issue reporters and people asking questions or complaining. Particular thanks to Floris Bruynooghe and Ronny Pfannschmidt for their great coding contributions and many others for feedback and help. best, holger krekel Changes between 2.0.0 and 2.0.1 ---------------------------------------------- - refine and unify initial capturing so that it works nicely even if the logging module is used on an early-loaded conftest.py file or plugin. - fix issue12 - show plugin versions with "--version" and "--traceconfig" and also document how to add extra information to reporting test header - fix issue17 (import-* reporting issue on python3) by requiring py>1.4.0 (1.4.1 is going to include it) - fix issue10 (numpy arrays truth checking) by refining assertion interpretation in py lib - fix issue15: make nose compatibility tests compatible with python3 (now that nose-1.0 supports python3) - remove somewhat surprising "same-conftest" detection because it ignores conftest.py when they appear in several subdirs. - improve assertions ("not in"), thanks Floris Bruynooghe - improve behaviour/warnings when running on top of "python -OO" (assertions and docstrings are turned off, leading to potential false positives) - introduce a pytest_cmdline_processargs(args) hook to allow dynamic computation of command line arguments. This fixes a regression because py.test prior to 2.0 allowed to set command line options from conftest.py files which so far pytest-2.0 only allowed from ini-files now. - fix issue7: assert failures in doctest modules. unexpected failures in doctests will not generally show nicer, i.e. within the doctest failing context. - fix issue9: setup/teardown functions for an xfail-marked test will report as xfail if they fail but report as normally passing (not xpassing) if they succeed. This only is true for "direct" setup/teardown invocations because teardown_class/ teardown_module cannot closely relate to a single test. - fix issue14: no logging errors at process exit - refinements to "collecting" output on non-ttys - refine internal plugin registration and --traceconfig output - introduce a mechanism to prevent/unregister plugins from the command line, see http://pytest.org/latest/plugins.html#cmdunregister - activate resultlog plugin by default - fix regression wrt yielded tests which due to the collection-before-running semantics were not setup as with pytest 1.3.4. Note, however, that the recommended and much cleaner way to do test parametrization remains the "pytest_generate_tests" mechanism, see the docs. pytest-2.8.7/doc/en/announce/release-2.0.0.rst0000664000175000017500000001203712651247335021213 0ustar ronnyronny00000000000000py.test 2.0.0: asserts++, unittest++, reporting++, config++, docs++ =========================================================================== Welcome to pytest-2.0.0, a major new release of "py.test", the rapid easy Python testing tool. There are many new features and enhancements, see below for summary and detailed lists. A lot of long-deprecated code has been removed, resulting in a much smaller and cleaner implementation. See the new docs with examples here: http://pytest.org/2.0.0/index.html A note on packaging: pytest used to part of the "py" distribution up until version py-1.3.4 but this has changed now: pytest-2.0.0 only contains py.test related code and is expected to be backward-compatible to existing test code. If you want to install pytest, just type one of:: pip install -U pytest easy_install -U pytest Many thanks to all issue reporters and people asking questions or complaining. Particular thanks to Floris Bruynooghe and Ronny Pfannschmidt for their great coding contributions and many others for feedback and help. best, holger krekel New Features ----------------------- - new invocations through Python interpreter and from Python:: python -m pytest # on all pythons >= 2.5 or from a python program:: import pytest ; pytest.main(arglist, pluginlist) see http://pytest.org/2.0.0/usage.html for details. - new and better reporting information in assert expressions if comparing lists, sequences or strings. see http://pytest.org/2.0.0/assert.html#newreport - new configuration through ini-files (setup.cfg or tox.ini recognized), for example:: [pytest] norecursedirs = .hg data* # don't ever recurse in such dirs addopts = -x --pyargs # add these command line options by default see http://pytest.org/2.0.0/customize.html - improved standard unittest support. In general py.test should now better be able to run custom unittest.TestCases like twisted trial or Django based TestCases. Also you can now run the tests of an installed 'unittest' package with py.test:: py.test --pyargs unittest - new "-q" option which decreases verbosity and prints a more nose/unittest-style "dot" output. - many many more detailed improvements details Fixes ----------------------- - fix issue126 - introduce py.test.set_trace() to trace execution via PDB during the running of tests even if capturing is ongoing. - fix issue124 - make reporting more resilient against tests opening files on filedescriptor 1 (stdout). - fix issue109 - sibling conftest.py files will not be loaded. (and Directory collectors cannot be customized anymore from a Directory's conftest.py - this needs to happen at least one level up). - fix issue88 (finding custom test nodes from command line arg) - fix issue93 stdout/stderr is captured while importing conftest.py - fix bug: unittest collected functions now also can have "pytestmark" applied at class/module level Important Notes -------------------- * The usual way in pre-2.0 times to use py.test in python code was to import "py" and then e.g. use "py.test.raises" for the helper. This remains valid and is not planned to be deprecated. However, in most examples and internal code you'll find "import pytest" and "pytest.raises" used as the recommended default way. * pytest now first performs collection of the complete test suite before running any test. This changes for example the semantics of when pytest_collectstart/pytest_collectreport are called. Some plugins may need upgrading. * The pytest package consists of a 400 LOC core.py and about 20 builtin plugins, summing up to roughly 5000 LOCs, including docstrings. To be fair, it also uses generic code from the "pylib", and the new "py" package to help with filesystem and introspection/code manipulation. (Incompatible) Removals ----------------------------- - py.test.config is now only available if you are in a test run. - the following (mostly already deprecated) functionality was removed: - removed support for Module/Class/... collection node definitions in conftest.py files. They will cause nothing special. - removed support for calling the pre-1.0 collection API of "run()" and "join" - removed reading option values from conftest.py files or env variables. This can now be done much much better and easier through the ini-file mechanism and the "addopts" entry in particular. - removed the "disabled" attribute in test classes. Use the skipping and pytestmark mechanism to skip or xfail a test class. - py.test.collect.Directory does not exist anymore and it is not possible to provide an own "Directory" object. If you have used this and don't know what to do, get in contact. We'll figure something out. Note that pytest_collect_directory() is still called but any return value will be ignored. This allows to keep old code working that performed for example "py.test.skip()" in collect() to prevent recursion into directory trees if a certain dependency or command line option is missing. see :ref:`changelog` for more detailed changes. pytest-2.8.7/doc/en/announce/index.rst0000664000175000017500000000131012651247335020237 0ustar ronnyronny00000000000000 Release announcements =========================================== .. toctree:: :maxdepth: 2 release-2.8.6 release-2.8.5 release-2.8.4 release-2.8.3 release-2.8.2 release-2.7.2 release-2.7.1 release-2.7.0 release-2.6.3 release-2.6.2 release-2.6.1 release-2.6.0 release-2.5.2 release-2.5.1 release-2.5.0 release-2.4.2 release-2.4.1 release-2.4.0 release-2.3.5 release-2.3.4 release-2.3.3 release-2.3.2 release-2.3.1 release-2.3.0 release-2.2.4 release-2.2.2 release-2.2.1 release-2.2.0 release-2.1.3 release-2.1.2 release-2.1.1 release-2.1.0 release-2.0.3 release-2.0.2 release-2.0.1 release-2.0.0 pytest-2.8.7/doc/en/_themes/0000775000175000017500000000000012651247336016222 5ustar ronnyronny00000000000000pytest-2.8.7/doc/en/_themes/flask_theme_support.py0000664000175000017500000001141312651247335022651 0ustar ronnyronny00000000000000# flasky extensions. flasky pygments style based on tango style from pygments.style import Style from pygments.token import Keyword, Name, Comment, String, Error, \ Number, Operator, Generic, Whitespace, Punctuation, Other, Literal class FlaskyStyle(Style): background_color = "#f8f8f8" default_style = "" styles = { # No corresponding class for the following: #Text: "", # class: '' Whitespace: "underline #f8f8f8", # class: 'w' Error: "#a40000 border:#ef2929", # class: 'err' Other: "#000000", # class 'x' Comment: "italic #8f5902", # class: 'c' Comment.Preproc: "noitalic", # class: 'cp' Keyword: "bold #004461", # class: 'k' Keyword.Constant: "bold #004461", # class: 'kc' Keyword.Declaration: "bold #004461", # class: 'kd' Keyword.Namespace: "bold #004461", # class: 'kn' Keyword.Pseudo: "bold #004461", # class: 'kp' Keyword.Reserved: "bold #004461", # class: 'kr' Keyword.Type: "bold #004461", # class: 'kt' Operator: "#582800", # class: 'o' Operator.Word: "bold #004461", # class: 'ow' - like keywords Punctuation: "bold #000000", # class: 'p' # because special names such as Name.Class, Name.Function, etc. # are not recognized as such later in the parsing, we choose them # to look the same as ordinary variables.

To use this style in your Sphinx documentation, follow this guide: 1. put this folder as _themes into your docs folder. Alternatively you can also use git submodules to check out the contents there. 2. add this to your conf.py: sys.path.append(os.path.abspath('_themes')) html_theme_path = ['_themes'] html_theme = 'flask' The following themes exist: - 'flask' - the standard flask documentation theme for large projects - 'flask_small' - small one-page theme. Intended to be used by very small addon libraries for flask. The following options exist for the flask_small theme: [options] index_logo = '' filename of a picture in _static to be used as replacement for the h1 in the index.rst file. index_logo_height = 120px height of the index logo github_fork = '' repository name on github for the "fork me" badge pytest-2.8.7/doc/en/_themes/LICENSE0000664000175000017500000000337512651247335017236 0ustar ronnyronny00000000000000Copyright (c) 2010 by Armin Ronacher.

If using Python 2.5 or above, you may use this function as a context manager:: >>> with raises(ZeroDivisionError): ... 1/0 .. note:: When using ``pytest.raises`` as a context manager, it's worthwhile to note that normal context manager rules apply and that the exception raised *must* be the final line in the scope of the context manager. Lines of code after that, within the scope of the context manager will not be executed. For example:: >>> with raises(OSError) as err: assert 1 == 1 # this will execute as expected raise OSError(errno.EEXISTS, 'directory exists') assert err.errno == errno.EEXISTS # this will not execute Instead, the following approach must be taken (note the difference in scope):: >>> with raises(OSError) as err: assert 1 == 1 # this will execute as expected raise OSError(errno.EEXISTS, 'directory exists') assert err.errno == errno.EEXISTS # this will now execute Or you can specify a callable by passing a to-be-called lambda:: >>> raises(ZeroDivisionError, lambda: 1/0) or you can specify an arbitrary callable with arguments:: >>> def f(x): return 1/x ... >>> raises(ZeroDivisionError, f, 0) >>> raises(ZeroDivisionError, f, x=0) A third possibility is to use a string to be executed:: >>> raises(ZeroDivisionError, "f(0)") Performance note: ----------------- Similar to caught exception objects in Python, explicitly clearing local references to returned ``py.code.ExceptionInfo`` objects can help the Python interpreter speed up its garbage collection. Clearing those references breaks a reference cycle (``ExceptionInfo`` --> caught exception --> frame stack raising the exception --> current frame stack --> local variables --> ``ExceptionInfo``) which makes Python keep all objects referenced from that cycle (including all local variables in the current frame) alive until the next cyclic garbage collection run.

Pluggy uses semantic versioning. Breaking changes are only foreseen for Major releases (incremented X in "X.Y.Z"). If you want to use pluggy in your project you should thus use a dependency restriction like "pluggy>=0.1.0,<1.0" to avoid surprises. pluggy is concerned with hook specification, hook implementations and hook calling. For any given hook specification a hook call invokes up to N implementations. A hook implementation can influence its position and type of execution: if attributed "tryfirst" or "trylast" it will be tried to execute first or last. However, if attributed "hookwrapper" an implementation can wrap all calls to non-hookwrapper implementations. A hookwrapper can thus execute some code ahead and after the execution of other hooks. Hook specification is done by way of a regular python function where both the function name and the names of all its arguments are significant. Each hook implementation function is verified against the original specification function, including the names of all its arguments. To allow for hook specifications to evolve over the livetime of a project, hook implementations can accept less arguments. One can thus add new arguments and semantics to a hook specification by adding another argument typically without breaking existing hook implementations. The chosen approach is meant to let a hook designer think carefuly about which objects are needed by an extension writer. By contrast, subclass-based extension mechanisms often expose a lot more state and behaviour than needed, thus restricting future developments. Pluggy currently consists of functionality for: - a way to register new hook specifications. Without a hook specification no hook calling can be performed. - a registry of plugins which contain hook implementation functions. It is possible to register plugins for which a hook specification is not yet known and validate all hooks when the system is in a more referentially consistent state. Setting an "optionalhook" attribution to a hook implementation will avoid PluginValidationError's if a specification is missing. This allows to have optional integration between plugins. - a "hook" relay object from which you can launch 1:N calls to registered hook implementation functions - a mechanism for ordering hook implementation functions - mechanisms for two different type of 1:N calls: "firstresult" for when the call should stop when the first implementation returns a non-None result. And the other (default) way of guaranteeing that all hook implementations will be called and their non-None result collected. - mechanisms for "historic" extension points such that all newly registered functions will receive all hook calls that happened before their registration. - a mechanism for discovering plugin objects which are based on setuptools based entry points. - a simple tracing mechanism, including tracing of plugin calls and their arguments.

If C is a subclass of View, then C(x) creates a proxy object around the object x. The actual class of the proxy is not C in general, but a *subclass* of C determined by the rules below. To avoid confusion we call view class the class of the proxy (a subclass of C, so of View) and object class the class of x. Attributes and methods not found in the proxy are automatically read on x. Other operations like setting attributes are performed on the proxy, as determined by its view class. The object x is available from the proxy as its __obj__ attribute. The view class selection is determined by the __view__ tuples and the optional __viewkey__ method. By default, the selected view class is the most specific subclass of C whose __view__ mentions the class of x. If no such subclass is found, the search proceeds with the parent object classes. For example, C(True) will first look for a subclass of C with __view__ = (..., bool, ...) and only if it doesn't find any look for one with __view__ = (..., int, ...), and then ..., object,... If everything fails the class C itself is considered to be the default. Alternatively, the view class selection can be driven by another aspect of the object x, instead of the class of x, by overriding __viewkey__. See last example at the end of this module.
