6.2.5

pytest 6.2.5 (2021-08-29)

Trivial/Internal Changes

• #8494: Python 3.10 is now supported.
• #9040: Enable compatibility with pluggy 1.0 or later.

6.2.4

pytest 6.2.4 (2021-05-04)

Bug Fixes

• #8539: Fixed assertion rewriting on Python 3.10.

6.2.3

pytest 6.2.3 (2021-04-03)

Bug Fixes

• #8414: pytest used to create directories under /tmp with world-readable
  permissions. This means that any user in the system was able to read
  information written by tests in temporary directories (such as those created by
  the tmp_path/tmpdir fixture). Now the directories are created with
  private permissions.

  pytest used silenty use a pre-existing /tmp/pytest-of-<username> directory,
  even if owned by another user. This means another user could pre-create such a
  directory and gain control of another user's temporary directory. Now such a
  condition results in an error.

6.2.2

pytest 6.2.2 (2021-01-25)

Bug Fixes

• #8152: Fixed "(<Skipped instance>)" being shown as a skip reason in the verbose test summary line when the reason is empty.
• #8249: Fix the faulthandler plugin for occasions when running with twisted.logger and using pytest --capture=no.

6.2.1

pytest 6.2.1 (2020-12-15)

Bug Fixes

• #7678: Fixed bug where ImportPathMismatchError would be raised for files compiled in
  the host and loaded later from an UNC mounted path (Windows).

• #8132: Fixed regression in approx: in 6.2.0 approx no longer raises
  TypeError when dealing with non-numeric types, falling back to normal comparison.
  Before 6.2.0, array types like tf.DeviceArray fell through to the scalar case,
  and happened to compare correctly to a scalar if they had only one element.
  After 6.2.0, these types began failing, because they inherited neither from
  standard Python number hierarchy nor from numpy.ndarray.

  approx now converts arguments to numpy.ndarray if they expose the array
  protocol and are not scalars. This treats array-like objects like numpy arrays,
  regardless of size.

6.2.0

pytest 6.2.0 (2020-12-12)

Breaking Changes

• #7808: pytest now supports python3.6+ only.

Deprecations

• #7469: Directly constructing/calling the following classes/functions is now deprecated:

  • _pytest.cacheprovider.Cache
  • _pytest.cacheprovider.Cache.for_config()
  • _pytest.cacheprovider.Cache.clear_cache()
  • _pytest.cacheprovider.Cache.cache_dir_from_config()
  • _pytest.capture.CaptureFixture
  • _pytest.fixtures.FixtureRequest
  • _pytest.fixtures.SubRequest
  • _pytest.logging.LogCaptureFixture
  • _pytest.pytester.Pytester
  • _pytest.pytester.Testdir
  • _pytest.recwarn.WarningsRecorder
  • _pytest.recwarn.WarningsChecker
  • _pytest.tmpdir.TempPathFactory
  • _pytest.tmpdir.TempdirFactory

  These have always been considered private, but now issue a deprecation warning, which may become a hard error in pytest 7.0.0.

• #7530: The --strict command-line option has been deprecated, use --strict-markers instead.

  We have plans to maybe in the future to reintroduce --strict and make it an encompassing flag for all strictness
  related options (--strict-markers and --strict-config at the moment, more might be introduced in the future).

• #7988: The @pytest.yield_fixture decorator/function is now deprecated. Use pytest.fixture instead.

  yield_fixture has been an alias for fixture for a very long time, so can be search/replaced safely.

Features

• #5299: pytest now warns about unraisable exceptions and unhandled thread exceptions that occur in tests on Python>=3.8.
  See unraisable for more information.

• #7425: New pytester fixture, which is identical to testdir but its methods return pathlib.Path when appropriate instead of py.path.local.

  This is part of the movement to use pathlib.Path objects internally, in order to remove the dependency to py in the future.

  Internally, the old Testdir <_pytest.pytester.Testdir> is now a thin wrapper around Pytester <_pytest.pytester.Pytester>, preserving the old interface.

• #7695: A new hook was added, pytest_markeval_namespace which should return a dictionary.
  This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers.

  Pseudo example

  conftest.py:

  def pytest_markeval_namespace():
      return {"color": "red"}
  

  test_func.py:

  @pytest.mark.skipif("color == 'blue'", reason="Color is not red")
  def test_func():
      assert False
  

• #8006: It is now possible to construct a ~pytest.MonkeyPatch object directly as pytest.MonkeyPatch(),
  in cases when the monkeypatch fixture cannot be used. Previously some users imported it
  from the private _pytest.monkeypatch.MonkeyPatch namespace.

  Additionally, MonkeyPatch.context <pytest.MonkeyPatch.context> is now a classmethod,
  and can be used as with MonkeyPatch.context() as mp: .... This is the recommended way to use
  MonkeyPatch directly, since unlike the monkeypatch fixture, an instance created directly
  is not undo()-ed automatically.

Improvements

• #1265: Added an __str__ implementation to the ~pytest.pytester.LineMatcher class which is returned from pytester.run_pytest().stdout and similar. It returns the entire output, like the existing str() method.

• #2044: Verbose mode now shows the reason that a test was skipped in the test's terminal line after the "SKIPPED", "XFAIL" or "XPASS".

• #7469 The types of builtin pytest fixtures are now exported so they may be used in type annotations of test functions.
  The newly-exported types are:

  • pytest.FixtureRequest for the request fixture.
  • pytest.Cache for the cache fixture.
  • pytest.CaptureFixture[str] for the capfd and capsys fixtures.
  • pytest.CaptureFixture[bytes] for the capfdbinary and capsysbinary fixtures.
  • pytest.LogCaptureFixture for the caplog fixture.
  • pytest.Pytester for the pytester fixture.
  • pytest.Testdir for the testdir fixture.
  • pytest.TempdirFactory for the tmpdir_factory fixture.
  • pytest.TempPathFactory for the tmp_path_factory fixture.
  • pytest.MonkeyPatch for the monkeypatch fixture.
  • pytest.WarningsRecorder for the recwarn fixture.

  Constructing them is not supported (except for MonkeyPatch); they are only meant for use in type annotations.
  Doing so will emit a deprecation warning, and may become a hard-error in pytest 7.0.

  Subclassing them is also not supported. This is not currently enforced at runtime, but is detected by type-checkers such as mypy.

• #7527: When a comparison between namedtuple <collections.namedtuple> instances of the same type fails, pytest now shows the differing field names (possibly nested) instead of their indexes.

• #7615: Node.warn <_pytest.nodes.Node.warn> now permits any subclass of Warning, not just PytestWarning <pytest.PytestWarning>.

• #7701: Improved reporting when using --collected-only. It will now show the number of collected tests in the summary stats.

• #7710: Use strict equality comparison for non-numeric types in pytest.approx instead of
  raising TypeError.

  This was the undocumented behavior before 3.7, but is now officially a supported feature.

• #7938: New --sw-skip argument which is a shorthand for --stepwise-skip.

• #8023: Added 'node_modules' to default value for norecursedirs.

• #8032: doClassCleanups <unittest.TestCase.doClassCleanups> (introduced in unittest in Python and 3.8) is now called appropriately.

Bug Fixes

• #4824: Fixed quadratic behavior and improved performance of collection of items using autouse fixtures and xunit fixtures.
• #7758: Fixed an issue where some files in packages are getting lost from --lf even though they contain tests that failed. Regressed in pytest 5.4.0.
• #7911: Directories created by by tmp_path and tmpdir are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites.
• #7913: Fixed a crash or hang in pytester.spawn <_pytest.pytester.Pytester.spawn> when the readline module is involved.
• #7951: Fixed handling of recursive symlinks when collecting tests.
• #7981: Fixed symlinked directories not being followed during collection. Regressed in pytest 6.1.0.
• #8016: Fixed only one doctest being collected when using pytest --doctest-modules path/to/an/__init__.py.

Improved Documentation

• #7429: Add more information and use cases about skipping doctests.
• #7780: Classes which should not be inherited from are now marked final class in the API reference.
• #7872: _pytest.config.argparsing.Parser.addini() accepts explicit None and "string".
• #7878: In pull request section, ask to commit after editing changelog and authors file.

Trivial/Internal Changes

• #7802: The attrs dependency requirement is now >=19.2.0 instead of >=17.4.0.
• #8014: .pyc files created by pytest's assertion rewriting now conform to the newer PEP-552 format on Python>=3.7.
  (These files are internal and only interpreted by pytest itself.)

6.1.2

pytest 6.1.2 (2020-10-28)

Bug Fixes

• #7758: Fixed an issue where some files in packages are getting lost from --lf even though they contain tests that failed. Regressed in pytest 5.4.0.
• #7911: Directories created by tmpdir are now considered stale after 3 days without modification (previous value was 3 hours) to avoid deleting directories still in use in long running test suites.

Improved Documentation

• #7815: Improve deprecation warning message for pytest._fillfuncargs().

6.1.1

pytest 6.1.1 (2020-10-03)

Bug Fixes

• #7807: Fixed regression in pytest 6.1.0 causing incorrect rootdir to be determined in some non-trivial cases where parent directories have config files as well.
• #7814: Fixed crash in header reporting when testpaths is used and contains absolute paths (regression in 6.1.0).

6.1.0

pytest 6.1.0 (2020-09-26)

Breaking Changes

• #5585: As per our policy, the following features which have been deprecated in the 5.X series are now
  removed:

  • The funcargnames read-only property of FixtureRequest, Metafunc, and Function classes. Use fixturenames attribute.
  • @pytest.fixture no longer supports positional arguments, pass all arguments by keyword instead.
  • Direct construction of Node subclasses now raise an error, use from_parent instead.
  • The default value for junit_family has changed to xunit2. If you require the old format, add junit_family=xunit1 to your configuration file.
  • The TerminalReporter no longer has a writer attribute. Plugin authors may use the public functions of the TerminalReporter instead of accessing the TerminalWriter object directly.
  • The --result-log option has been removed. Users are recommended to use the pytest-reportlog plugin instead.

  For more information consult
  Deprecations and Removals in the docs.

Deprecations

• #6981: The pytest.collect module is deprecated: all its names can be imported from pytest directly.

• #7097: The pytest._fillfuncargs function is deprecated. This function was kept
  for backward compatibility with an older plugin.

  It's functionality is not meant to be used directly, but if you must replace
  it, use function._request._fillfixtures() instead, though note this is not
  a public API and may break in the future.

• #7210: The special -k '-expr' syntax to -k is deprecated. Use -k 'not expr'
  instead.

  The special -k 'expr:' syntax to -k is deprecated. Please open an issue
  if you use this and want a replacement.

• #7255: The pytest_warning_captured <_pytest.hookspec.pytest_warning_captured> hook is deprecated in favor
  of pytest_warning_recorded <_pytest.hookspec.pytest_warning_recorded>, and will be removed in a future version.

• #7648: The gethookproxy() and isinitpath() methods of FSCollector and Package are deprecated;
  use self.session.gethookproxy() and self.session.isinitpath() instead.
  This should work on all pytest versions.

Features

• #7667: New --durations-min command-line flag controls the minimal duration for inclusion in the slowest list of tests shown by --durations. Previously this was hard-coded to 0.005s.

Improvements

• #6681: Internal pytest warnings issued during the early stages of initialization are now properly handled and can filtered through filterwarnings or --pythonwarnings/-W.

  This also fixes a number of long standing issues: #2891, #7620, #7426.

• #7572: When a plugin listed in required_plugins is missing or an unknown config key is used with --strict-config, a simple error message is now shown instead of a stacktrace.

• #7685: Added two new attributes rootpath <_pytest.config.Config.rootpath> and inipath <_pytest.config.Config.inipath> to Config <_pytest.config.Config>.
  These attributes are pathlib.Path versions of the existing rootdir <_pytest.config.Config.rootdir> and inifile <_pytest.config.Config.inifile> attributes,
  and should be preferred over them when possible.

• #7780: Public classes which are not designed to be inherited from are now marked @final.
  Code which inherits from these classes will trigger a type-checking (e.g. mypy) error, but will still work in runtime.
  Currently the final designation does not appear in the API Reference but hopefully will in the future.

Bug Fixes

• #1953: Fixed error when overwriting a parametrized fixture, while also reusing the super fixture value.

  # conftest.py
  import pytest
  
  
  @pytest.fixture(params=[1, 2])
  def foo(request):
      return request.param
  
  
  # test_foo.py
  import pytest
  
  
  @pytest.fixture
  def foo(foo):
      return foo * 2
  

• #4984: Fixed an internal error crash with IndexError: list index out of range when
  collecting a module which starts with a decorated function, the decorator
  raises, and assertion rewriting is enabled.

• #7591: pylint shouldn't complain anymore about unimplemented abstract methods when inheriting from File <non-python tests>.

• #7628: Fixed test collection when a full path without a drive letter was passed to pytest on Windows (for example \projects\tests\test.py instead of c:\projects\tests\pytest.py).

• #7638: Fix handling of command-line options that appear as paths but trigger an OS-level syntax error on Windows, such as the options used internally by pytest-xdist.

• #7742: Fixed INTERNALERROR when accessing locals / globals with faulty exec.

Improved Documentation

• #1477: Removed faq.rst and its reference in contents.rst.

Trivial/Internal Changes

• #7536: The internal junitxml plugin has rewritten to use xml.etree.ElementTree.
  The order of attributes in XML elements might differ. Some unneeded escaping is
  no longer performed.
• #7587: The dependency on the more-itertools package has been removed.
• #7631: The result type of capfd.readouterr() <_pytest.capture.CaptureFixture.readouterr> (and similar) is no longer a namedtuple,
  but should behave like one in all respects. This was done for technical reasons.
• #7671: When collecting tests, pytest finds test classes and functions by examining the
  attributes of python objects (modules, classes and instances). To speed up this
  process, pytest now ignores builtin attributes (like __class__,
  __delattr__ and __new__) without consulting the python_classes and
  python_functions configuration options and without passing them to plugins
  using the pytest_pycollect_makeitem <_pytest.hookspec.pytest_pycollect_makeitem> hook.

6.0.2

pytest 6.0.2 (2020-09-04)

Bug Fixes

• #7148: Fixed --log-cli potentially causing unrelated print output to be swallowed.
• #7672: Fixed log-capturing level restored incorrectly if caplog.set_level is called more than once.
• #7686: Fixed NotSetType.token being used as the parameter ID when the parametrization list is empty.
  Regressed in pytest 6.0.0.
• #7707: Fix internal error when handling some exceptions that contain multiple lines or the style uses multiple lines (--tb=line for example).
