Removals

• #5180: As per
  our policy, the following features have been deprecated in the 4.X
  series and are now removed:

  • Request.getfuncargvalue: use Request.getfixturevalue
    instead.
  • pytest.raises and pytest.warns no longer support strings as
    the second argument.
  • message parameter of pytest.raises.
  • pytest.raises, pytest.warns and ParameterSet.param now use
    native keyword-only syntax. This might change the exception
    message from previous versions, but they still raise TypeError
    on unknown keyword arguments as before.
  • pytest.config global variable.
  • tmpdir_factory.ensuretemp method.
  • pytest_logwarning hook.
  • RemovedInPytest4Warning warning type.
  • request is now a reserved name for fixtures.

  For more information consult Deprecations and
  Removals in
  the docs.

• #5565: Removed
  unused support code for
  unittest2.

  The unittest2 backport module is no longer necessary since Python
  3.3+, and the small amount of code in pytest to support it also
  doesn't seem to be used: after removed, all tests still pass
  unchanged.

  Although our policy is to introduce a deprecation period before
  removing any features or support for third party libraries, because
  this code is apparently not used at all (even if unittest2 is used
  by a test suite executed by pytest), it was decided to remove it in
  this release.

  If you experience a regression because of this, please file an
  issue.

• #5615:
  pytest.fail, pytest.xfail and pytest.skip no longer support
  bytes for the message argument.

  This was supported for Python 2 where it was tempting to use
  "message" instead of u"message".

  Python 3 code is unlikely to pass bytes to these functions. If you
  do, please decode it to an str beforehand.

Features

• #5564: New
  Config.invocation_args attribute containing the unchanged
  arguments passed to pytest.main().
• #5576: New
  NUMBER
  option for doctests to ignore irrelevant differences in
  floating-point numbers. Inspired by Sébastien Boisgérault's
  numtest extension for
  doctest.

Improvements

• #5471: JUnit
  XML now includes a timestamp and hostname in the testsuite tag.

• #5707: Time
  taken to run the test suite now includes a human-readable
  representation when it takes over 60 seconds, for example:

  ===== 2 failed in 102.70s (0:01:42) =====
  

Bug Fixes

• #4344: Fix
  RuntimeError/StopIteration when trying to collect package with
  "__init__.py" only.
• #5115: Warnings
  issued during pytest_configure are explicitly not treated as
  errors, even if configured as such, because it otherwise completely
  breaks pytest.
• #5477: The XML
  file produced by --junitxml now correctly contain a <testsuites>
  root element.
• #5523: Fixed
  using multiple short options together in the command-line (for
  example -vs) in Python 3.8+.
• #5524: Fix
  issue where tmp_path and tmpdir would not remove directories
  containing files marked as read-only, which could lead to pytest
  crashing when executed a second time with the --basetemp option.
• #5537: Replace
  importlib_metadata backport with importlib.metadata from the
  standard library on Python 3.8+.
• #5578: Improve
  type checking for some exception-raising functions (pytest.xfail,
  pytest.skip, etc) so they provide better error messages when users
  meant to use marks (for example @pytest.xfail instead of
  @pytest.mark.xfail).
• #5606: Fixed
  internal error when test functions were patched with objects that
  cannot be compared for truth values against others, like numpy
  arrays.
• #5634:
  pytest.exit is now correctly handled in unittest cases. This
  makes unittest cases handle quit from pytest's pdb correctly.
• #5650: Improved
  output when parsing an ini configuration file fails.
• #5701: Fix
  collection of staticmethod objects defined with
  functools.partial.
• #5734: Skip
  async generator test functions, and update the warning message to
  refer to async def functions.

Improved Documentation

• #5669: Add
  docstring for Testdir.copy_example.

Trivial/Internal Changes

• #5095: XML
  files of the xunit2 family are now validated against the schema by
  pytest's own test suite to avoid future regressions.
• #5516: Cache
  node splitting function which can improve collection performance in
  very large test suites.
• #5603:
  Simplified internal SafeRepr class and removed some dead code.
• #5664: When
  invoking pytest's own testsuite with PYTHONDONTWRITEBYTECODE=1,
  the test_xfail_handling test no longer fails.
• #5684: Replace
  manual handling of OSError.errno in the codebase by new OSError
  subclasses (PermissionError, FileNotFoundError, etc.).

4.6.5

• #5478: Fix encode error when using unicode strings in exceptions with pytest.raises.

• #5524: Fix issue where tmp_path and tmpdir would not remove directories containing files marked as read-only,
  which could lead to pytest crashing when executed a second time with the --basetemp option.

• #5547: --step-wise now handles xfail(strict=True) markers properly.

• #5650: Improved output when parsing an ini configuration file fails.
