1.4.34
====================================================================
- fix issue119 / pytest issue708 where tmpdir may fail to make numbered directories
when the filesystem is case-insensitive.
1.4.33
====================================================================
- avoid imports in calls to py.path.local().fnmatch(). Thanks Andreas Pelme for
the PR.
- fix issue106: Naive unicode encoding when calling fspath() in python2. Thanks Tiago Nobrega for the PR.
- fix issue110: unittest.TestCase.assertWarns fails with py imported.
1.4.32
====================================================================
- fix issue70: added ability to copy all stat info in py.path.local.copy.
- make TerminalWriter.fullwidth a property. This results in the correct
value when the terminal gets resized.
- update supported html tags to include recent additions.
Thanks Denis Afonso for the PR.
- Remove internal code in ``Source.compile`` meant to support earlier Python 3 versions that produced the side effect
of leaving ``None`` in ``sys.modules`` when called (see pytest-dev/pytest#2103).
Thanks Bruno Oliveira for the PR.
1.4.31
==================================================
- fix local().copy(dest, mode=True) to also work
with unicode.
- pass better error message with svn EEXIST paths
1.4.30
==================================================
- fix issue68 an assert with a multiline list comprehension
was not reported correctly. Thanks Henrik Heibuerger.
1.4.29
==================================================
- fix issue55: revert a change to the statement finding algorithm
which is used by pytest for generating tracebacks.
Thanks Daniel Hahler for initial analysis.
- fix pytest issue254 for when traceback rendering can't
find valid source code. Thanks Ionel Cristian Maries.
1.4.28
==================================================
- fix issue64 -- dirpath regression when "abs=True" is passed.
Thanks Gilles Dartiguelongue.
1.4.27
==================================================
- fix issue59: point to new repo site
- allow a new ensuresyspath="append" mode for py.path.local.pyimport()
so that a neccessary import path is appended instead of prepended to
sys.path
- strike undocumented, untested argument to py.path.local.pypkgpath
- speed up py.path.local.dirpath by a factor of 10
1.4.26
==================================================
- avoid calling normpath twice in py.path.local
- py.builtin._reraise properly reraises under Python3 now.
- fix issue53 - remove module index, thanks jenisys.
- allow posix path separators when "fnmatch" is called.
Thanks Christian Long for the complete PR.
1.4.25
==================================================
- fix issue52: vaguely fix py25 compat of py.path.local (it's not
officially supported), also fix docs
- fix pytest issue 589: when checking if we have a recursion error
check for the specific "maximum recursion depth" text of the exception.
1.4.24
==================================================
- Fix retrieving source when an else: line has an other statement on
the same line.
- add localpath read_text/write_text/read_bytes/write_bytes methods
as shortcuts and clearer bytes/text interfaces for read/write.
Adapted from a PR from Paul Moore.
1.4.23
==================================================
- use newer apipkg version which makes attribute access on
alias modules resolve to None rather than an ImportError.
This helps with code that uses inspect.getframeinfo()
on py34 which causes a complete walk on sys.modules
thus triggering the alias module to resolve and blowing
up with ImportError. The negative side is that something
like "py.test.X" will now result in None instead of "importerror: pytest"
if pytest is not installed. But you shouldn't import "py.test"
anyway anymore.
- adapt one svn test to only check for any exception instead
of specific ones because different svn versions cause different
errors and we don't care.
1.4.22
==================================================
- refactor class-level registry on ForkedFunc child start/finish
event to become instance based (i.e. passed into the constructor)
1.4.21
==================================================
- ForkedFunc now has class-level register_on_start/on_exit()
methods to allow adding information in the boxed process.
Thanks Marc Schlaich.
- ForkedFunc in the child opens in "auto-flush" mode for
stdout/stderr so that when a subprocess dies you can see
its output even if it didn't flush itself.
- refactor traceback generation in light of pytest issue 364
(shortening tracebacks). you can now set a new traceback style
on a per-entry basis such that a caller can force entries to be
isplayed as short or long entries.
- win32: py.path.local.sysfind(name) will preferrably return files with
extensions so that if "X" and "X.bat" or "X.exe" is on the PATH,
one of the latter two will be returned.
1.4.20
==================================================
- ignore unicode decode errors in xmlescape. Thanks Anatoly Bubenkoff.
- on python2 modify traceback.format_exception_only to match python3
behaviour, namely trying to print unicode for Exception instances
- use a safer way for serializing exception reports (helps to fix
pytest issue413)
Changes between 1.4.18 and 1.4.19
==================================================
- merge in apipkg fixes
- some micro-optimizations in py/_code/code.py for speeding
up pytest runs. Thanks Alex Gaynor for initiative.
- check PY_COLORS=1 or PY_COLORS=0 to force coloring/not-coloring
for py.io.TerminalWriter() independently from capabilities
of the output file. Thanks Marc Abramowitz for the PR.
- some fixes to unicode handling in assertion handling.
Thanks for the PR to Floris Bruynooghe. (This helps
to fix pytest issue 319).
- depend on setuptools presence, remove distribute_setup
Changes between 1.4.17 and 1.4.18
==================================================
- introduce path.ensure_dir() as a synonym for ensure(..., dir=1)
- some unicode/python3 related fixes wrt to path manipulations
(if you start passing unicode particular in py2 you might
still get problems, though)
Changes between 1.4.16 and 1.4.17
==================================================
- make py.io.TerminalWriter() prefer colorama if it is available
and avoid empty lines when separator-lines are printed by
being defensive and reducing the working terminalwidth by 1
- introduce optional "expanduser" argument to py.path.local
to that local("~", expanduser=True) gives the home
directory of "user".
Changes between 1.4.15 and 1.4.16
==================================================
- fix issue35 - define __gt__ ordering between a local path
and strings
- fix issue36 - make chdir() work even if os.getcwd() fails.
- add path.exists/isdir/isfile/islink shortcuts
- introduce local path.as_cwd() context manager.
- introduce p.write(ensure=1) and p.open(ensure=1)
where ensure triggers creation of neccessary parent
dirs.
Changes between 1.4.14 and 1.4.15
==================================================
- majorly speed up some common calling patterns with
LocalPath.listdir()/join/check/stat functions considerably.
- fix an edge case with fnmatch where a glob style pattern appeared
in an absolute path.
Changes between 1.4.13 and 1.4.14
==================================================
- fix dupfile to work with files that don't
carry a mode. Thanks Jason R. Coombs.
Changes between 1.4.12 and 1.4.13
==================================================
- fix getting statementrange/compiling a file ending
in a comment line without newline (on python2.5)
- for local paths you can pass "mode=True" to a copy()
in order to copy permission bits (underlying mechanism
is using shutil.copymode)
- add paths arguments to py.path.local.sysfind to restrict
search to the diretories in the path.
- add isdir/isfile/islink to path.stat() objects allowing to perform
multiple checks without calling out multiple times
- drop py.path.local.__new__ in favour of a simpler __init__
- iniconfig: allow "name:value" settings in config files, no space after
"name" required
- fix issue 27 - NameError in unlikely untested case of saferepr
Changes between 1.4.11 and 1.4.12
==================================================
- fix python2.4 support - for pre-AST interpreters re-introduce
old way to find statements in exceptions (closes pytest issue 209)
- add tox.ini to distribution
- fix issue23 - print *,** args information in tracebacks,
thanks Manuel Jacob
Changes between 1.4.10 and 1.4.11
==================================================
- use _ast to determine statement ranges when printing tracebacks -
avoiding multi-second delays on some large test modules
- fix an internal test to not use class-denoted pytest_funcarg__
- fix a doc link to bug tracker
- try to make terminal.write() printing more robust against
unicodeencode/decode problems, amend according test
- introduce py.builtin.text and py.builtin.bytes
to point to respective str/unicode (py2) and bytes/str (py3) types
- fix error handling on win32/py33 for ENODIR
Changes between 1.4.9 and 1.4.10
==================================================
- terminalwriter: default to encode to UTF8 if no encoding is defined
on the output stream
- issue22: improve heuristic for finding the statementrange in exceptions
Changes between 1.4.8 and 1.4.9
==================================================

and "#" only mark a comment at the stripped start of a line
- include recent apipkg-1.2
- change internal terminalwriter.line/reline logic to more nicely
support file spinners

- fix issue7: source.getstatementrange() now raises proper error
if no valid statement can be found

--xml output is broken.
- make source.getstatementrange() more resilent about non-python code frames
(as seen from jnja2)
- make trackeback recursion detection more resilent
about the eval magic of a decorator library
- iniconfig: add support for ; as comment starter
- properly handle lists in xmlgen on python3

(used by pytest)
Changes between 1.4.3 and 1.4.4
==================================================
- a few fixes and assertion related refinements for pytest-2.1
- guard py.code.Code and getfslineno against bogus input

leading to misrepresentation of import-errors in test modules
- fix py.error.* attribute pypy access issue
- allow path.samefile(arg) to succeed when arg is a relative filename
- fix (pytest-) issue20 path.samefile(relpath) works as expected now
- fix (pytest-) issue8 len(long_list) now shows the lenght of the list
Changes between 1.3.4 and 1.4.0
==================================================
- py.test was moved to a separate "pytest" package. What remains is
a stub hook which will proxy ``import py.test`` to ``pytest``.
- all command line tools ("py.cleanup/lookup/countloc/..." moved
to "pycmd" package)
- removed the old and deprecated "py.magic" namespace
- use apipkg-1.1 and make py.apipkg.initpkg|ApiModule available

(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
Changes between 1.3.1 and 1.3.2
==================================================
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
Changes between 1.3.0 and 1.3.1
==================================================
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)
Changes between 1.2.1 and 1.3.0
==================================================
- 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
Changes between 1.2.1 and 1.2.0
=====================================
- 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
Changes between 1.2 and 1.1.1
=====================================
- 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
Changes between 1.1.1 and 1.1.0
=====================================
- 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
Changes between 1.1.0 and 1.0.2
=====================================
* 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
Changes between 1.0.1 and 1.0.2
=====================================
* 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.
Changes between 1.0.0 and 1.0.1
=====================================
* 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
Changes between 1.0.0b9 and 1.0.0
=====================================
* more terse reporting try to show filesystem path relatively to current dir
* improve xfail output a bit
Changes between 1.0.0b8 and 1.0.0b9
=====================================
* 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)
Changes between 1.0.0b7 and 1.0.0b8
=====================================
* 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.
Changes between 1.0.0b3 and 1.0.0b7
=============================================
* 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
Changes between 1.0.0b1 and 1.0.0b3
=============================================
* 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.
Changes between 0.9.2 and 1.0.0b1
=============================================
* introduced new "funcarg" setup method,
see doc/test/funcarg.txt
* introduced plugin architecuture 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
Changes between 0.9.1 and 0.9.2
===============================
* 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
Changes between 0.9.0 and 0.9.1

**NOTE**: this library is in **maintenance mode** and should not be used in new code.
The py lib is a Python development support library featuring
the following tools and modules:
* ``py.path``: uniform local and svn path objects
* ``py.apipkg``: explicit API control and lazy-importing
* ``py.iniconfig``: easy parsing of .ini files
* ``py.code``: dynamic code generation and introspection (deprecated, moved to ``pytest``).
**NOTE**: prior to the 1.4 release this distribution used to
contain py.test which is now its own package, see http://pytest.org

**NOTE**: this library is in **maintenance mode** and should not be used in new code.
The py lib is a Python development support library featuring
the following tools and modules:
* ``py.path``: uniform local and svn path objects
* ``py.apipkg``: explicit API control and lazy-importing
* ``py.iniconfig``: easy parsing of .ini files
* ``py.code``: dynamic code generation and introspection (deprecated, moved to ``pytest``).
**NOTE**: prior to the 1.4 release this distribution used to
contain py.test which is now its own package, see http://pytest.org
For questions and more information please visit http://py.readthedocs.org

"""View base class.
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__.

py.io
=======
The 'py' lib provides helper classes for capturing IO during
execution of a program.
IO Capturing examples
===============================================
``py.io.StdCapture``
---------------------------
Basic Example::
>>> import py
>>> capture = py.io.StdCapture()
>>> print "hello"
>>> out,err = capture.reset()
>>> out.strip() == "hello"
True
For calling functions you may use a shortcut::
>>> import py
>>> def f(): print "hello"
>>> res, out, err = py.io.StdCapture.call(f)
>>> out.strip() == "hello"
True
``py.io.StdCaptureFD``
---------------------------
If you also want to capture writes to the stdout/stderr
filedescriptors you may invoke::
>>> import py, sys
>>> capture = py.io.StdCaptureFD(out=False, in_=False)
>>> sys.stderr.write("world")
>>> out,err = capture.reset()
>>> err
'world'

py.xml: simple pythonic xml/html file generation
====================================================
Motivation
==========
There are a plethora of frameworks and libraries to generate
xml and html trees. However, many of them are large, have a
steep learning curve and are often hard to debug. Not to
speak of the fact that they are frameworks to begin with.
.. _xist: http://www.livinglogic.de/Python/xist/index.html
a pythonic object model , please
================================
The py lib offers a pythonic way to generate xml/html, based on
ideas from xist_ which `uses python class objects`_ to build
xml trees. However, xist_'s implementation is somewhat heavy
because it has additional goals like transformations and
supporting many namespaces. But its basic idea is very easy.
.. _`uses python class objects`: http://www.livinglogic.de/Python/xist/Howto.html
generating arbitrary xml structures
-----------------------------------
With ``py.xml.Namespace`` you have the basis
to generate custom xml-fragments on the fly::
class ns(py.xml.Namespace):
"my custom xml namespace"
doc = ns.books(
ns.book(
ns.author("May Day"),
ns.title("python for java programmers"),),
ns.book(
ns.author("why"),
ns.title("Java for Python programmers"),),
publisher="N.N",
)
print doc.unicode(indent=2).encode('utf8')
will give you this representation::
May Daypython for java programmerswhyJava for Python programmers
In a sentence: positional arguments are child-tags and
keyword-arguments are attributes.
On a side note, you'll see that the unicode-serializer
supports a nice indentation style which keeps your generated
html readable, basically through emulating python's white
space significance by putting closing-tags rightmost and
almost invisible at first glance :-)
basic example for generating html
---------------------------------
Consider this example::
from py.xml import html # html namespace
paras = "First Para", "Second para"
doc = html.html(
html.head(
html.meta(name="Content-Type", value="text/html; charset=latin1")),
html.body(
[html.p(p) for p in paras]))
print unicode(doc).encode('latin1')
Again, tags are objects which contain tags and have attributes.
More exactly, Tags inherit from the list type and thus can be
manipulated as list objects. They additionally support a default
way to represent themselves as a serialized unicode object.
If you happen to look at the py.xml implementation you'll
note that the tag/namespace implementation consumes some 50 lines
with another 50 lines for the unicode serialization code.
CSS-styling your html Tags
--------------------------
One aspect where many of the huge python xml/html generation
frameworks utterly fail is a clean and convenient integration
of CSS styling. Often, developers are left alone with keeping
CSS style definitions in sync with some style files
represented as strings (often in a separate .css file). Not
only is this hard to debug but the missing abstractions make
it hard to modify the styling of your tags or to choose custom
style representations (inline, html.head or external). Add the
Browers usual tolerance of messyness and errors in Style
references and welcome to hell, known as the domain of
developing web applications :-)
By contrast, consider this CSS styling example::
class my(html):
"my initial custom style"
class body(html.body):
style = html.Style(font_size = "120%")
class h2(html.h2):
style = html.Style(background = "grey")
class p(html.p):
style = html.Style(font_weight="bold")
doc = my.html(
my.head(),
my.body(
my.h2("hello world"),
my.p("bold as bold can")
)
)
print doc.unicode(indent=2)
This will give you a small'n mean self contained
represenation by default::
