pytest 5.1.0 (2019-08-15)

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.).
