Changelog

3.4.2

=========================

Bug Fixes

• Removed progress information when capture option is no. (3203 <https://github.com/pytest-dev/pytest/issues/3203>_)

• Refactor check of bindir from exists to isdir. (3241 <https://github.com/pytest-dev/pytest/issues/3241>_)

• Fix TypeError issue when using approx with a Decimal value.
  (3247 <https://github.com/pytest-dev/pytest/issues/3247>_)

• Fix reference cycle generated when using the request fixture. (3249 <https://github.com/pytest-dev/pytest/issues/3249>_)

• [tool:pytest] sections in *.cfg files passed by the -c option are
  now properly recognized. (3260 <https://github.com/pytest-dev/pytest/issues/3260>_)

Improved Documentation

• Add logging plugin to plugins list. (3209 <https://github.com/pytest-dev/pytest/issues/3209>_)

Trivial/Internal Changes

• Fix minor typo in fixture.rst (3259 <https://github.com/pytest-dev/pytest/issues/3259>_)

3.4.1

=========================

Bug Fixes

• Move import of doctest.UnexpectedException to top-level to avoid possible
  errors when using --pdb. (1810 <https://github.com/pytest-dev/pytest/issues/1810>_)

• Added printing of captured stdout/stderr before entering pdb, and improved a
  test which was giving false negatives about output capturing. (3052 <https://github.com/pytest-dev/pytest/issues/3052>_)

• Fix ordering of tests using parametrized fixtures which can lead to fixtures
  being created more than necessary. (3161 <https://github.com/pytest-dev/pytest/issues/3161>_)

• Fix bug where logging happening at hooks outside of "test run" hooks would
  cause an internal error. (3184 <https://github.com/pytest-dev/pytest/issues/3184>_)

• Detect arguments injected by unittest.mock.patch decorator correctly when
  pypi mock.patch is installed and imported. (3206 <https://github.com/pytest-dev/pytest/issues/3206>_)

• Errors shown when a pytest.raises() with match= fails are now cleaner
  on what happened: When no exception was raised, the "matching '...'" part got
  removed as it falsely implies that an exception was raised but it didn't
  match. When a wrong exception was raised, it's now thrown (like
  pytest.raised() without match= would) instead of complaining about
  the unmatched text. (3222 <https://github.com/pytest-dev/pytest/issues/3222>_)

• Fixed output capture handling in doctests on macOS. (985 <https://github.com/pytest-dev/pytest/issues/985>_)

Improved Documentation

• Add Sphinx parameter docs for match and message args to
  pytest.raises. (3202 <https://github.com/pytest-dev/pytest/issues/3202>_)

Trivial/Internal Changes

• pytest has changed the publication procedure and is now being published to
  PyPI directly from Travis. (3060 <https://github.com/pytest-dev/pytest/issues/3060>_)

• Rename ParameterSet._for_parameterize() to _for_parametrize() in
  order to comply with the naming convention. (3166 <https://github.com/pytest-dev/pytest/issues/3166>_)

• Skip failing pdb/doctest test on mac. (985 <https://github.com/pytest-dev/pytest/issues/985>_)

3.4.0

=========================

Deprecations and Removals

• All pytest classes now subclass object for better Python 2/3 compatibility.
  This should not affect user code except in very rare edge cases. (2147 <https://github.com/pytest-dev/pytest/issues/2147>_)

Features

• Introduce empty_parameter_set_mark ini option to select which mark to
  apply when pytest.mark.parametrize is given an empty set of parameters.
  Valid options are skip (default) and xfail. Note that it is planned
  to change the default to xfail in future releases as this is considered
  less error prone. (2527 <https://github.com/pytest-dev/pytest/issues/2527>_)

• Incompatible change: after community feedback the logging <https://docs.pytest.org/en/latest/logging.html>_ functionality has
  undergone some changes. Please consult the logging documentation <https://docs.pytest.org/en/latest/logging.htmlincompatible-changes-in-pytest-3-4>_
  for details. (3013 <https://github.com/pytest-dev/pytest/issues/3013>_)

• Console output falls back to "classic" mode when capturing is disabled (-s),
  otherwise the output gets garbled to the point of being useless. (3038 <https://github.com/pytest-dev/pytest/issues/3038>_)

• New pytest_runtest_logfinish <https://docs.pytest.org/en/latest/writing_plugins.html_pytest.hookspec.pytest_runtest_logfinish>_
  hook which is called when a test item has finished executing, analogous to
  pytest_runtest_logstart <https://docs.pytest.org/en/latest/writing_plugins.html_pytest.hookspec.pytest_runtest_start>.
  (3101 <https://github.com/pytest-dev/pytest/issues/3101>)

• Improve performance when collecting tests using many fixtures. (3107 <https://github.com/pytest-dev/pytest/issues/3107>_)

• New caplog.get_records(when) method which provides access to the captured
  records for the "setup", "call" and "teardown"
  testing stages. (3117 <https://github.com/pytest-dev/pytest/issues/3117>_)

• New fixture record_xml_attribute that allows modifying and inserting
  attributes on the <testcase> xml node in JUnit reports. (3130 <https://github.com/pytest-dev/pytest/issues/3130>_)

• The default cache directory has been renamed from .cache to
  .pytest_cache after community feedback that the name .cache did not
  make it clear that it was used by pytest. (3138 <https://github.com/pytest-dev/pytest/issues/3138>_)

• Colorize the levelname column in the live-log output. (3142 <https://github.com/pytest-dev/pytest/issues/3142>_)

Bug Fixes

• Fix hanging pexpect test on MacOS by using flush() instead of wait().
  (2022 <https://github.com/pytest-dev/pytest/issues/2022>_)

• Fix restoring Python state after in-process pytest runs with the
  pytester plugin; this may break tests using multiple inprocess
  pytest runs if later ones depend on earlier ones leaking global interpreter
  changes. (3016 <https://github.com/pytest-dev/pytest/issues/3016>_)

• Fix skipping plugin reporting hook when test aborted before plugin setup
  hook. (3074 <https://github.com/pytest-dev/pytest/issues/3074>_)

• Fix progress percentage reported when tests fail during teardown. (3088 <https://github.com/pytest-dev/pytest/issues/3088>_)

• Incompatible change: -o/--override option no longer eats all the
  remaining options, which can lead to surprising behavior: for example,
  pytest -o foo=1 /path/to/test.py would fail because /path/to/test.py
  would be considered as part of the -o command-line argument. One
  consequence of this is that now multiple configuration overrides need
  multiple -o flags: pytest -o foo=1 -o bar=2. (3103 <https://github.com/pytest-dev/pytest/issues/3103>_)

Improved Documentation

• Document hooks (defined with historic=True) which cannot be used with
  hookwrapper=True. (2423 <https://github.com/pytest-dev/pytest/issues/2423>_)

• Clarify that warning capturing doesn't change the warning filter by default.
  (2457 <https://github.com/pytest-dev/pytest/issues/2457>_)

• Clarify a possible confusion when using pytest_fixture_setup with fixture
  functions that return None. (2698 <https://github.com/pytest-dev/pytest/issues/2698>_)

• Fix the wording of a sentence on doctest flags used in pytest. (3076 <https://github.com/pytest-dev/pytest/issues/3076>_)

• Prefer https://*.readthedocs.io over http://*.rtfd.org for links in
  the documentation. (3092 <https://github.com/pytest-dev/pytest/issues/3092>_)

• Improve readability (wording, grammar) of Getting Started guide (3131 <https://github.com/pytest-dev/pytest/issues/3131>_)

• Added note that calling pytest.main multiple times from the same process is
  not recommended because of import caching. (3143 <https://github.com/pytest-dev/pytest/issues/3143>_)

Trivial/Internal Changes

• Show a simple and easy error when keyword expressions trigger a syntax error
  (for example, "-k foo and import" will show an error that you can not use
  the import keyword in expressions). (2953 <https://github.com/pytest-dev/pytest/issues/2953>_)

• Change parametrized automatic test id generation to use the __name__
  attribute of functions instead of the fallback argument name plus counter.
  (2976 <https://github.com/pytest-dev/pytest/issues/2976>_)

• Replace py.std with stdlib imports. (3067 <https://github.com/pytest-dev/pytest/issues/3067>_)

• Corrected 'you' to 'your' in logging docs. (3129 <https://github.com/pytest-dev/pytest/issues/3129>_)

3.3.2

=========================

Bug Fixes

• pytester: ignore files used to obtain current user metadata in the fd leak
  detector. (2784 <https://github.com/pytest-dev/pytest/issues/2784>_)

• Fix memory leak where objects returned by fixtures were never destructed
  by the garbage collector. (2981 <https://github.com/pytest-dev/pytest/issues/2981>_)

• Fix conversion of pyargs to filename to not convert symlinks on Python 2. (2985 <https://github.com/pytest-dev/pytest/issues/2985>_)

• PYTEST_DONT_REWRITE is now checked for plugins too rather than only for
  test modules. (2995 <https://github.com/pytest-dev/pytest/issues/2995>_)

Improved Documentation

• Add clarifying note about behavior of multiple parametrized arguments (3001 <https://github.com/pytest-dev/pytest/issues/3001>_)

Trivial/Internal Changes

• Code cleanup. (3015 <https://github.com/pytest-dev/pytest/issues/3015>,
  3021 <https://github.com/pytest-dev/pytest/issues/3021>)

• Clean up code by replacing imports and references of _ast to ast. (3018 <https://github.com/pytest-dev/pytest/issues/3018>_)

3.3.1

=========================

Bug Fixes

• Fix issue about -p no:<plugin> having no effect. (2920 <https://github.com/pytest-dev/pytest/issues/2920>_)

• Fix regression with warnings that contained non-strings in their arguments in
  Python 2. (2956 <https://github.com/pytest-dev/pytest/issues/2956>_)

• Always escape null bytes when setting PYTEST_CURRENT_TEST. (2957 <https://github.com/pytest-dev/pytest/issues/2957>_)

• Fix ZeroDivisionError when using the testmon plugin when no tests
  were actually collected. (2971 <https://github.com/pytest-dev/pytest/issues/2971>_)

• Bring back TerminalReporter.writer as an alias to
  TerminalReporter._tw. This alias was removed by accident in the 3.3.0
  release. (2984 <https://github.com/pytest-dev/pytest/issues/2984>_)

• The pytest-capturelog plugin is now also blacklisted, avoiding errors when
  running pytest with it still installed. (3004 <https://github.com/pytest-dev/pytest/issues/3004>_)

Improved Documentation

• Fix broken link to plugin pytest-localserver. (2963 <https://github.com/pytest-dev/pytest/issues/2963>_)

Trivial/Internal Changes

• Update github "bugs" link in CONTRIBUTING.rst (2949 <https://github.com/pytest-dev/pytest/issues/2949>_)

3.3.0

=========================

Deprecations and Removals

• Pytest no longer supports Python 2.6 and 3.3. Those Python versions
  are EOL for some time now and incur maintenance and compatibility costs on
  the pytest core team, and following up with the rest of the community we
  decided that they will no longer be supported starting on this version. Users
  which still require those versions should pin pytest to <3.3. (2812 <https://github.com/pytest-dev/pytest/issues/2812>_)

• Remove internal _preloadplugins() function. This removal is part of the
  pytest_namespace() hook deprecation. (2636 <https://github.com/pytest-dev/pytest/issues/2636>_)

• Internally change CallSpec2 to have a list of marks instead of a broken
  mapping of keywords. This removes the keywords attribute of the internal
  CallSpec2 class. (2672 <https://github.com/pytest-dev/pytest/issues/2672>_)

• Remove ParameterSet.deprecated_arg_dict - its not a public api and the lack
  of the underscore was a naming error. (2675 <https://github.com/pytest-dev/pytest/issues/2675>_)

• Remove the internal multi-typed attribute Node._evalskip and replace it
  with the boolean Node._skipped_by_mark. (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• The params list passed to pytest.fixture is now for
  all effects considered immutable and frozen at the moment of the pytest.fixture
  call. Previously the list could be changed before the first invocation of the fixture
  allowing for a form of dynamic parametrization (for example, updated from command-line options),
  but this was an unwanted implementation detail which complicated the internals and prevented
  some internal cleanup. See issue 2959 <https://github.com/pytest-dev/pytest/issues/2959>_
  for details and a recommended workaround.

Features

• pytest_fixture_post_finalizer hook can now receive a request
  argument. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• Replace the old introspection code in compat.py that determines the available
  arguments of fixtures with inspect.signature on Python 3 and
  funcsigs.signature on Python 2. This should respect __signature__
  declarations on functions. (2267 <https://github.com/pytest-dev/pytest/issues/2267>_)

• Report tests with global pytestmark variable only once. (2549 <https://github.com/pytest-dev/pytest/issues/2549>_)

• Now pytest displays the total progress percentage while running tests. The
  previous output style can be set by configuring the console_output_style
  setting to classic. (2657 <https://github.com/pytest-dev/pytest/issues/2657>_)

• Match warns signature to raises by adding match keyword. (2708 <https://github.com/pytest-dev/pytest/issues/2708>_)

• Pytest now captures and displays output from the standard logging module.
  The user can control the logging level to be captured by specifying options
  in pytest.ini, the command line and also during individual tests using
  markers. Also, a caplog fixture is available that enables users to test
  the captured log during specific tests (similar to capsys for example).
  For more information, please see the logging docs <https://docs.pytest.org/en/latest/logging.html>. This feature was
  introduced by merging the popular pytest-catchlog <https://pypi.org/project/pytest-catchlog/> plugin, thanks to Thomas Hisch <https://github.com/thisch>. Be advised that during the merging the
  backward compatibility interface with the defunct pytest-capturelog has
  been dropped. (2794 <https://github.com/pytest-dev/pytest/issues/2794>)

• Add allow_module_level kwarg to pytest.skip(), enabling to skip the
  whole module. (2808 <https://github.com/pytest-dev/pytest/issues/2808>_)

• Allow setting file_or_dir, -c, and -o in PYTEST_ADDOPTS. (2824 <https://github.com/pytest-dev/pytest/issues/2824>_)

• Return stdout/stderr capture results as a namedtuple, so out and
  err can be accessed by attribute. (2879 <https://github.com/pytest-dev/pytest/issues/2879>_)

• Add capfdbinary, a version of capfd which returns bytes from
  readouterr(). (2923 <https://github.com/pytest-dev/pytest/issues/2923>_)

• Add capsysbinary a version of capsys which returns bytes from
  readouterr(). (2934 <https://github.com/pytest-dev/pytest/issues/2934>_)

• Implement feature to skip setup.py files when run with
  --doctest-modules. (502 <https://github.com/pytest-dev/pytest/issues/502>_)

Bug Fixes

• Resume output capturing after capsys/capfd.disabled() context manager.
  (1993 <https://github.com/pytest-dev/pytest/issues/1993>_)

• pytest_fixture_setup and pytest_fixture_post_finalizer hooks are now
  called for all conftest.py files. (2124 <https://github.com/pytest-dev/pytest/issues/2124>_)

• If an exception happens while loading a plugin, pytest no longer hides the
  original traceback. In Python 2 it will show the original traceback with a new
  message that explains in which plugin. In Python 3 it will show 2 canonized
  exceptions, the original exception while loading the plugin in addition to an
  exception that pytest throws about loading a plugin. (2491 <https://github.com/pytest-dev/pytest/issues/2491>_)

• capsys and capfd can now be used by other fixtures. (2709 <https://github.com/pytest-dev/pytest/issues/2709>_)

• Internal pytester plugin properly encodes bytes arguments to
  utf-8. (2738 <https://github.com/pytest-dev/pytest/issues/2738>_)

• testdir now uses use the same method used by tmpdir to create its
  temporary directory. This changes the final structure of the testdir
  directory slightly, but should not affect usage in normal scenarios and
  avoids a number of potential problems. (2751 <https://github.com/pytest-dev/pytest/issues/2751>_)

• Pytest no longer complains about warnings with unicode messages being
  non-ascii compatible even for ascii-compatible messages. As a result of this,
  warnings with unicode messages are converted first to an ascii representation
  for safety. (2809 <https://github.com/pytest-dev/pytest/issues/2809>_)

• Change return value of pytest command when --maxfail is reached from
  2 (interrupted) to 1 (failed). (2845 <https://github.com/pytest-dev/pytest/issues/2845>_)

• Fix issue in assertion rewriting which could lead it to rewrite modules which
  should not be rewritten. (2939 <https://github.com/pytest-dev/pytest/issues/2939>_)

• Handle marks without description in pytest.ini. (2942 <https://github.com/pytest-dev/pytest/issues/2942>_)

Trivial/Internal Changes

• pytest now depends on attrs <https://pypi.org/project/attrs/>_ for internal
  structures to ease code maintainability. (2641 <https://github.com/pytest-dev/pytest/issues/2641>_)

• Refactored internal Python 2/3 compatibility code to use six. (2642 <https://github.com/pytest-dev/pytest/issues/2642>_)

• Stop vendoring pluggy - we're missing out on its latest changes for not
  much benefit (2719 <https://github.com/pytest-dev/pytest/issues/2719>_)

• Internal refactor: simplify ascii string escaping by using the
  backslashreplace error handler in newer Python 3 versions. (2734 <https://github.com/pytest-dev/pytest/issues/2734>_)

• Remove unnecessary mark evaluator in unittest plugin (2767 <https://github.com/pytest-dev/pytest/issues/2767>_)

• Calls to Metafunc.addcall now emit a deprecation warning. This function
  is scheduled to be removed in pytest-4.0. (2876 <https://github.com/pytest-dev/pytest/issues/2876>_)

• Internal move of the parameterset extraction to a more maintainable place.
  (2877 <https://github.com/pytest-dev/pytest/issues/2877>_)

• Internal refactoring to simplify scope node lookup. (2910 <https://github.com/pytest-dev/pytest/issues/2910>_)

• Configure pytest to prevent pip from installing pytest in unsupported
  Python versions. (2922 <https://github.com/pytest-dev/pytest/issues/2922>_)

3.2.5

=========================

Bug Fixes

• Remove py<1.5 restriction from pytest as this can cause version
  conflicts in some installations. (2926 <https://github.com/pytest-dev/pytest/issues/2926>_)

3.2.4

=========================

Bug Fixes

• Fix the bug where running with --pyargs will result in items with
  empty parent.nodeid if run from a different root directory. (2775 <https://github.com/pytest-dev/pytest/issues/2775>_)

• Fix issue with pytest.parametrize if argnames was specified as keyword arguments.
  (2819 <https://github.com/pytest-dev/pytest/issues/2819>_)

• Strip whitespace from marker names when reading them from INI config. (2856 <https://github.com/pytest-dev/pytest/issues/2856>_)

• Show full context of doctest source in the pytest output, if the line number of
  failed example in the docstring is < 9. (2882 <https://github.com/pytest-dev/pytest/issues/2882>_)

• Match fixture paths against actual path segments in order to avoid matching folders which share a prefix.
  (2836 <https://github.com/pytest-dev/pytest/issues/2836>_)

Improved Documentation

• Introduce a dedicated section about conftest.py. (1505 <https://github.com/pytest-dev/pytest/issues/1505>_)

• Explicitly mention xpass in the documentation of xfail. (1997 <https://github.com/pytest-dev/pytest/issues/1997>_)

• Append example for pytest.param in the example/parametrize document. (2658 <https://github.com/pytest-dev/pytest/issues/2658>_)

• Clarify language of proposal for fixtures parameters (2893 <https://github.com/pytest-dev/pytest/issues/2893>_)

• List python 3.6 in the documented supported versions in the getting started
  document. (2903 <https://github.com/pytest-dev/pytest/issues/2903>_)

• Clarify the documentation of available fixture scopes. (538 <https://github.com/pytest-dev/pytest/issues/538>_)

• Add documentation about the python -m pytest invocation adding the
  current directory to sys.path. (911 <https://github.com/pytest-dev/pytest/issues/911>_)

3.2.3

=========================

Bug Fixes

• Fix crash in tab completion when no prefix is given. (2748 <https://github.com/pytest-dev/pytest/issues/2748>_)

• The equality checking function (__eq__) of MarkDecorator returns
  False if one object is not an instance of MarkDecorator. (2758 <https://github.com/pytest-dev/pytest/issues/2758>_)

• When running pytest --fixtures-per-test: don't crash if an item has no
  fixtureinfo attribute (e.g. doctests) (2788 <https://github.com/pytest-dev/pytest/issues/2788>)

Improved Documentation

• In help text of -k option, add example of using not to not select
  certain tests whose names match the provided expression. (1442 <https://github.com/pytest-dev/pytest/issues/1442>_)

• Add note in parametrize.rst about calling metafunc.parametrize
  multiple times. (1548 <https://github.com/pytest-dev/pytest/issues/1548>_)

Trivial/Internal Changes

• Set xfail_strict=True in pytest's own test suite to catch expected
  failures as soon as they start to pass. (2722 <https://github.com/pytest-dev/pytest/issues/2722>_)

• Fix typo in example of passing a callable to markers (in example/markers.rst)
  (2765 <https://github.com/pytest-dev/pytest/issues/2765>_)

3.2.2

=========================

Bug Fixes

• Calling the deprecated request.getfuncargvalue() now shows the source of
  the call. (2681 <https://github.com/pytest-dev/pytest/issues/2681>_)

• Allow tests declared as staticmethod to use fixtures. (2699 <https://github.com/pytest-dev/pytest/issues/2699>_)

• Fixed edge-case during collection: attributes which raised pytest.fail
  when accessed would abort the entire collection. (2707 <https://github.com/pytest-dev/pytest/issues/2707>_)

• Fix ReprFuncArgs with mixed unicode and UTF-8 args. (2731 <https://github.com/pytest-dev/pytest/issues/2731>_)

Improved Documentation

• In examples on working with custom markers, add examples demonstrating the
  usage of pytest.mark.MARKER_NAME.with_args in comparison with
  pytest.mark.MARKER_NAME.__call__ (2604 <https://github.com/pytest-dev/pytest/issues/2604>_)

• In one of the simple examples, use pytest_collection_modifyitems() to skip
  tests based on a command-line option, allowing its sharing while preventing a
  user error when acessing pytest.config before the argument parsing. (2653 <https://github.com/pytest-dev/pytest/issues/2653>_)

Trivial/Internal Changes

• Fixed minor error in 'Good Practices/Manual Integration' code snippet.
  (2691 <https://github.com/pytest-dev/pytest/issues/2691>_)

• Fixed typo in goodpractices.rst. (2721 <https://github.com/pytest-dev/pytest/issues/2721>_)

3.2.1

=========================

Bug Fixes

• Fixed small terminal glitch when collecting a single test item. (2579 <https://github.com/pytest-dev/pytest/issues/2579>_)

• Correctly consider / as the file separator to automatically mark plugin
  files for rewrite on Windows. (2591 <https://github.com/pytest- dev/pytest/issues/2591>_)

• Properly escape test names when setting PYTEST_CURRENT_TEST environment
  variable. (2644 <https://github.com/pytest-dev/pytest/issues/2644>_)

• Fix error on Windows and Python 3.6+ when sys.stdout has been replaced
  with a stream-like object which does not implement the full io module
  buffer protocol. In particular this affects pytest-xdist users on the
  aforementioned platform. (2666 <https://github.com/pytest- dev/pytest/issues/2666>_)

Improved Documentation

• Explicitly document which pytest features work with unittest. (2626 <https://github.com/pytest-dev/pytest/issues/2626>_)

3.2.0

=========================

Deprecations and Removals

• pytest.approx no longer supports >, >=, < and <=
  operators to avoid surprising/inconsistent behavior. See the approx docs <https://docs.pytest.org/en/latest/builtin.htmlpytest.approx>_ for more
  information. (2003 <https://github.com/pytest-dev/pytest/issues/2003>_)

• All old-style specific behavior in current classes in the pytest's API is
  considered deprecated at this point and will be removed in a future release.
  This affects Python 2 users only and in rare situations. (2147 <https://github.com/pytest-dev/pytest/issues/2147>_)

• A deprecation warning is now raised when using marks for parameters
  in pytest.mark.parametrize. Use pytest.param to apply marks to
  parameters instead. (2427 <https://github.com/pytest-dev/pytest/issues/2427>_)

Features

• Add support for numpy arrays (and dicts) to approx. (1994 <https://github.com/pytest-dev/pytest/issues/1994>_)

• Now test function objects have a pytestmark attribute containing a list
  of marks applied directly to the test function, as opposed to marks inherited
  from parent classes or modules. (2516 <https://github.com/pytest- dev/pytest/issues/2516>_)

• Collection ignores local virtualenvs by default; --collect-in-virtualenv
  overrides this behavior. (2518 <https://github.com/pytest- dev/pytest/issues/2518>_)

• Allow class methods decorated as staticmethod to be candidates for
  collection as a test function. (Only for Python 2.7 and above. Python 2.6
  will still ignore static methods.) (2528 <https://github.com/pytest- dev/pytest/issues/2528>_)

• Introduce mark.with_args in order to allow passing functions/classes as
  sole argument to marks. (2540 <https://github.com/pytest- dev/pytest/issues/2540>_)

• New cache_dir ini option: sets the directory where the contents of the
  cache plugin are stored. Directory may be relative or absolute path: if relative path, then
  directory is created relative to rootdir, otherwise it is used as is.
  Additionally path may contain environment variables which are expanded during
  runtime. (2543 <https://github.com/pytest-dev/pytest/issues/2543>_)

• Introduce the PYTEST_CURRENT_TEST environment variable that is set with
  the nodeid and stage (setup, call and teardown) of the test
  being currently executed. See the documentation <https://docs.pytest.org/en/latest/example/simple.htmlpytest-current-test- environment-variable>_ for more info. (2583 <https://github.com/pytest- dev/pytest/issues/2583>_)

• Introduced pytest.mark.filterwarnings mark which allows overwriting the
  warnings filter on a per test, class or module level. See the docs <https://docs.pytest.org/en/latest/warnings.htmlpytest-mark- filterwarnings>_ for more information. (2598 <https://github.com/pytest- dev/pytest/issues/2598>_)

• --last-failed now remembers forever when a test has failed and only
  forgets it if it passes again. This makes it easy to fix a test suite by
  selectively running files and fixing tests incrementally. (2621 <https://github.com/pytest-dev/pytest/issues/2621>_)

• New pytest_report_collectionfinish hook which allows plugins to add
  messages to the terminal reporting after collection has been finished
  successfully. (2622 <https://github.com/pytest-dev/pytest/issues/2622>_)

• Added support for PEP-415's <https://www.python.org/dev/peps/pep-0415/>_
  Exception.__suppress_context__. Now if a raise exception from None is
  caught by pytest, pytest will no longer chain the context in the test report.
  The behavior now matches Python's traceback behavior. (2631 <https://github.com/pytest-dev/pytest/issues/2631>_)

• Exceptions raised by pytest.fail, pytest.skip and pytest.xfail
  now subclass BaseException, making them harder to be caught unintentionally
  by normal code. (580 <https://github.com/pytest-dev/pytest/issues/580>_)

Bug Fixes

• Set stdin to a closed PIPE in pytester.py.Testdir.popen() for
  avoid unwanted interactive pdb (2023 <https://github.com/pytest- dev/pytest/issues/2023>_)

• Add missing encoding attribute to sys.std* streams when using
  capsys capture mode. (2375 <https://github.com/pytest- dev/pytest/issues/2375>_)

• Fix terminal color changing to black on Windows if colorama is imported
  in a conftest.py file. (2510 <https://github.com/pytest- dev/pytest/issues/2510>_)

• Fix line number when reporting summary of skipped tests. (2548 <https://github.com/pytest-dev/pytest/issues/2548>_)

• capture: ensure that EncodedFile.name is a string. (2555 <https://github.com/pytest-dev/pytest/issues/2555>_)

• The options --fixtures and --fixtures-per-test will now keep
  indentation within docstrings. (2574 <https://github.com/pytest- dev/pytest/issues/2574>_)

• doctests line numbers are now reported correctly, fixing pytest-sugar122 <https://github.com/Frozenball/pytest-sugar/issues/122>. (2610 <https://github.com/pytest-dev/pytest/issues/2610>)

• Fix non-determinism in order of fixture collection. Adds new dependency
  (ordereddict) for Python 2.6. (920 <https://github.com/pytest- dev/pytest/issues/920>_)

Improved Documentation

• Clarify pytest_configure hook call order. (2539 <https://github.com/pytest-dev/pytest/issues/2539>_)

• Extend documentation for testing plugin code with the pytester plugin.
  (971 <https://github.com/pytest-dev/pytest/issues/971>_)

Trivial/Internal Changes

• Update help message for --strict to make it clear it only deals with
  unregistered markers, not warnings. (2444 <https://github.com/pytest- dev/pytest/issues/2444>_)

• Internal code move: move code for pytest.approx/pytest.raises to own files in
  order to cut down the size of python.py (2489 <https://github.com/pytest- dev/pytest/issues/2489>_)

• Renamed the utility function _pytest.compat._escape_strings to
  _ascii_escaped to better communicate the function's purpose. (2533 <https://github.com/pytest-dev/pytest/issues/2533>_)

• Improve error message for CollectError with skip/skipif. (2546 <https://github.com/pytest-dev/pytest/issues/2546>_)

• Emit warning about yield tests being deprecated only once per generator.
  (2562 <https://github.com/pytest-dev/pytest/issues/2562>_)

• Ensure final collected line doesn't include artifacts of previous write.
  (2571 <https://github.com/pytest-dev/pytest/issues/2571>_)

• Fixed all flake8 errors and warnings. (2581 <https://github.com/pytest- dev/pytest/issues/2581>_)

• Added fix-lint tox environment to run automatic pep8 fixes on the code.
  (2582 <https://github.com/pytest-dev/pytest/issues/2582>_)

• Turn warnings into errors in pytest's own test suite in order to catch
  regressions due to deprecations more promptly. (2588 <https://github.com/pytest-dev/pytest/issues/2588>_)

• Show multiple issue links in CHANGELOG entries. (2620 <https://github.com/pytest-dev/pytest/issues/2620>_)

3.1.3

=========================

Bug Fixes

• Fix decode error in Python 2 for doctests in docstrings. (2434 <https://github.com/pytest-dev/pytest/issues/2434>_)

• Exceptions raised during teardown by finalizers are now suppressed until all
  finalizers are called, with the initial exception reraised. (2440 <https://github.com/pytest-dev/pytest/issues/2440>_)

• Fix incorrect "collected items" report when specifying tests on the command-
  line. (2464 <https://github.com/pytest-dev/pytest/issues/2464>_)

• deprecated_call in context-manager form now captures deprecation warnings
  even if the same warning has already been raised. Also, deprecated_call
  will always produce the same error message (previously it would produce
  different messages in context-manager vs. function-call mode). (2469 <https://github.com/pytest-dev/pytest/issues/2469>_)

• Fix issue where paths collected by pytest could have triple leading /
  characters. (2475 <https://github.com/pytest-dev/pytest/issues/2475>_)

• Fix internal error when trying to detect the start of a recursive traceback.
  (2486 <https://github.com/pytest-dev/pytest/issues/2486>_)

Improved Documentation

• Explicitly state for which hooks the calls stop after the first non-None
  result. (2493 <https://github.com/pytest-dev/pytest/issues/2493>_)

Trivial/Internal Changes

• Create invoke tasks for updating the vendored packages. (2474 <https://github.com/pytest-dev/pytest/issues/2474>_)

• Update copyright dates in LICENSE, README.rst and in the documentation.
  (2499 <https://github.com/pytest-dev/pytest/issues/2499>_)

3.1.2

=========================

Bug Fixes

• Required options added via pytest_addoption will no longer prevent using
  --help without passing them. (1999)

• Respect python_files in assertion rewriting. (2121)

• Fix recursion error detection when frames in the traceback contain objects
  that can't be compared (like numpy arrays). (2459)

• UnicodeWarning is issued from the internal pytest warnings plugin only
  when the message contains non-ascii unicode (Python 2 only). (2463)

• Added a workaround for Python 3.6 WindowsConsoleIO breaking due to Pytests's
  FDCapture. Other code using console handles might still be affected by the
  very same issue and might require further workarounds/fixes, i.e. colorama.
  (2467)

Improved Documentation

• Fix internal API links to pluggy objects. (2331)

• Make it clear that pytest.xfail stops test execution at the calling point
  and improve overall flow of the skipping docs. (810)

3.1.1

=========================

Bug Fixes

• pytest warning capture no longer overrides existing warning filters. The
  previous behaviour would override all filters and caused regressions in test
  suites which configure warning filters to match their needs. Note that as a
  side-effect of this is that DeprecationWarning and
  PendingDeprecationWarning are no longer shown by default. (2430)

• Fix issue with non-ascii contents in doctest text files. (2434)

• Fix encoding errors for unicode warnings in Python 2. (2436)

• pytest.deprecated_call now captures PendingDeprecationWarning in
  context manager form. (2441)

Improved Documentation

• Addition of towncrier for changelog management. (2390)

3.1.0

==================

New Features

• The pytest-warnings plugin has been integrated into the core and now pytest automatically
  captures and displays warnings at the end of the test session.

.. warning::

This feature may disrupt test suites which apply and treat warnings themselves, and can be
disabled in your pytest.ini:

.. code-block:: ini

 [pytest]
 addopts = -p no:warnings

See the warnings documentation page <https://docs.pytest.org/en/latest/warnings.html>_ for more
information.

Thanks nicoddemus_ for the PR.

• Added junit_suite_name ini option to specify root <testsuite> name for JUnit XML reports (533_).

• Added an ini option doctest_encoding to specify which encoding to use for doctest files.
  Thanks wheerd_ for the PR (2101_).

• pytest.warns now checks for subclass relationship rather than
  class equality. Thanks lesteve_ for the PR (2166_)

• pytest.raises now asserts that the error message matches a text or regex
  with the match keyword argument. Thanks Kriechi_ for the PR.

• pytest.param can be used to declare test parameter sets with marks and test ids.
  Thanks RonnyPfannschmidt_ for the PR.

Changes

• remove all internal uses of pytest_namespace hooks,
  this is to prepare the removal of preloadconfig in pytest 4.0
  Thanks to RonnyPfannschmidt_ for the PR.

• pytest now warns when a callable ids raises in a parametrized test. Thanks fogo_ for the PR.

• It is now possible to skip test classes from being collected by setting a
  __test__ attribute to False in the class body (2007). Thanks
  to syre for the report and lwm_ for the PR.

• Change junitxml.py to produce reports that comply with Junitxml schema.
  If the same test fails with failure in call and then errors in teardown
  we split testcase element into two, one containing the error and the other
  the failure. (2228) Thanks to kkoukiou for the PR.

• Testcase reports with a url attribute will now properly write this to junitxml.
  Thanks fushi_ for the PR (1874_).

• Remove common items from dict comparision output when verbosity=1. Also update
  the truncation message to make it clearer that pytest truncates all
  assertion messages if verbosity < 2 (1512).
  Thanks mattduck for the PR

• --pdbcls no longer implies --pdb. This makes it possible to use
  addopts=--pdbcls=module.SomeClass on pytest.ini. Thanks davidszotten_ for
  the PR (1952_).

• fix 2013_: turn RecordedWarning into namedtuple,
  to give it a comprehensible repr while preventing unwarranted modification.

• fix 2208_: ensure a iteration limit for pytest.compat.get_real_func.
  Thanks RonnyPfannschmidt for the report and PR.

• Hooks are now verified after collection is complete, rather than right after loading installed plugins. This
  makes it easy to write hooks for plugins which will be loaded during collection, for example using the
  pytest_plugins special variable (1821).
  Thanks nicoddemus for the PR.

• Modify pytest_make_parametrize_id() hook to accept argname as an
  additional parameter.
  Thanks unsignedint_ for the PR.

• Add venv to the default norecursedirs setting.
  Thanks The-Compiler_ for the PR.

• PluginManager.import_plugin now accepts unicode plugin names in Python 2.
  Thanks reutsharabani_ for the PR.

• fix 2308: When using both --lf and --ff, only the last failed tests are run.
  Thanks ojii for the PR.

• Replace minor/patch level version numbers in the documentation with placeholders.
  This significantly reduces change-noise as different contributors regnerate
  the documentation on different platforms.
  Thanks RonnyPfannschmidt_ for the PR.

• fix 2391: consider pytest_plugins on all plugin modules
  Thanks RonnyPfannschmidt for the PR.

Bug Fixes

• Fix AttributeError on sys.stdout.buffer / sys.stderr.buffer
  while using capsys fixture in python 3. (1407).
  Thanks to asottile.

• Change capture.py's DontReadFromInput class to throw io.UnsupportedOperation errors rather
  than ValueErrors in the fileno method (2276).
  Thanks metasyn and vlad-dragos_ for the PR.

• Fix exception formatting while importing modules when the exception message
  contains non-ascii characters (2336).
  Thanks fabioz for the report and nicoddemus_ for the PR.

• Added documentation related to issue (1937)
  Thanks skylarjhdownes for the PR.

• Allow collecting files with any file extension as Python modules (2369).
  Thanks Kodiologist for the PR.

• Show the correct error message when collect "parametrize" func with wrong args (2383).
  Thanks The-Compiler for the report and robin0371_ for the PR.
