1.11.0 (2021-11-04)¶

Support Python 3.11
Support NO_COLOR environment variable
Update vendored apipkg: 1.5 => 2.0

1.10.0 (2020-12-12)¶

Fix a regular expression DoS vulnerability in the py.path.svnwc SVN blame functionality (CVE-2020-29651)
Update vendored apipkg: 1.4 => 1.5
Update vendored iniconfig: 1.0.0 => 1.1.1

1.9.0 (2020-06-24)¶

Add type annotation stubs for the following modules:
- py.error
- py.iniconfig
- py.path (not including SVN paths)
- py.io
- py.xml
There are no plans to type other modules at this time.

The type annotations are provided in external .pyi files, not inline in the code, and may therefore contain small errors or omissions. If you use py in conjunction with a type checker, and encounter any type errors you believe should be accepted, please report it in an issue.

1.8.2 (2020-06-15)¶

On Windows, ``py.path.local``s which differ only in case now have the same Python hash value. Previously, such paths were considered equal but had different hashes, which is not allowed and breaks the assumptions made by dicts, sets and other users of hashes.

1.8.1 (2019-12-27)¶

Handle FileNotFoundError when trying to import pathlib in path.common on Python 3.4 (#207).
py.path.local.samefile now works correctly in Python 3 on Windows when dealing with symlinks.

1.8.0 (2019-02-21)¶

add "importlib" pyimport mode for python3.5+, allowing unimportable test suites to contain identically named modules.
fix LocalPath.as_cwd() not calling os.chdir() with None, when being invoked from a non-existing directory.

1.7.0 (2018-10-11)¶

fix #174: use shutil.get_terminal_size() in Python 3.3+ to determine the size of the terminal, which produces more accurate results than the previous method.
fix pytest-dev/pytest#2042: introduce new PY_IGNORE_IMPORTMISMATCH environment variable that suppresses ImportMismatchError exceptions when set to 1.

1.6.0 (2018-08-27)¶

add TerminalWriter.width_of_current_line (i18n version of TerminalWriter.chars_on_current_line), a read-only property that tracks how wide the current line is, attempting to take into account international characters in the calculation.

1.5.4 (2018-06-27)¶

fix pytest-dev/pytest#3451: don’t make assumptions about fs case sensitivity in make_numbered_dir.

1.5.3¶

fix #179: ensure we can support ‘from py.error import …’

1.5.2¶

fix #169, #170: error importing py.log on Windows: no module named syslog.

1.5.1¶

fix #167 - prevent pip from installing py in unsupported Python versions.

1.5.0¶

NOTE: this release has been removed from PyPI due to missing package metadata which caused a number of problems to py26 and py33 users. This issue was fixed in the 1.5.1 release.

python 2.6 and 3.3 are no longer supported
deprecate py.std and remove all internal uses
fix #73 turn py.error into an actual module
path join to / no longer produces leading double slashes
fix #82 - remove unsupportable aliases
fix python37 compatibility of path.sysfind on windows by correctly replacing vars
turn iniconfig and apipkg into vendored packages and ease de-vendoring for distributions
fix #68 remove invalid py.test.ensuretemp references
fix #25 - deprecate path.listdir(sort=callable)
add TerminalWriter.chars_on_current_line read-only property that tracks how many characters have been written to the current line.

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.

depend on setuptools presence, remove distribute_setup

Changes between 1.4.17 and 1.4.18¶

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

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

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¶

fix bug of path.visit() which would not recognize glob-style patterns for the “rec” recursion argument
changed iniconfig parsing to better conform, now the chars “;” 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
fix issue8: fix code and tests of svnurl/svnwc to work on subversion 1.7 - note that path.status(updates=1) will not properly work svn-17’s status –xml output is broken.
make source.getstatementrange() more resilent about non-python code frames (as seen from jnja2)

fix (pytest) issue23 - tmpdir argument now works on Python3.2 and WindowsXP (which apparently starts to offer os.symlink now)
better error message for syntax errors from compiled code
small fix to better deal with (un-)colored terminal output on windows

Changes between 1.4.0 and 1.4.1¶

fix issue1 - py.error.* classes to be pickleable

fix issue116: –doctestmodules work with __init__.py files as well
fix issue115: unify internal exception passthrough/catching/GeneratorExit

Changes between 1.3.2 and 1.3.3¶

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

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
