This PR updates pytest from 5.2.4 to 5.3.0.

Changelog

5.3.0

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

Deprecations
------------

- `6179 <https://github.com/pytest-dev/pytest/issues/6179>`_: The default value of ``junit_family`` option will change to ``xunit2`` in pytest 6.0, given
that this is the version supported by default in modern tools that manipulate this type of file.

In order to smooth the transition, pytest will issue a warning in case the ``--junitxml`` option
is given in the command line but ``junit_family`` is not explicitly configured in ``pytest.ini``.

For more information, `see the docs <https://docs.pytest.org/en/latest/deprecations.htmljunit-family-default-value-change-to-xunit2>`__.



Features
--------

- `4488 <https://github.com/pytest-dev/pytest/issues/4488>`_: The pytest team has created the `pytest-reportlog <https://github.com/pytest-dev/pytest-reportlog>`__
plugin, which provides a new ``--report-log=FILE`` option that writes *report logs* into a file as the test session executes.

Each line of the report log contains a self contained JSON object corresponding to a testing event,
such as a collection or a test result report. The file is guaranteed to be flushed after writing
each line, so systems can read and process events in real-time.

The plugin is meant to replace the ``--resultlog`` option, which is deprecated and meant to be removed
in a future release. If you use ``--resultlog``, please try out ``pytest-reportlog`` and
provide feedback.


- `4730 <https://github.com/pytest-dev/pytest/issues/4730>`_: When ``sys.pycache_prefix`` (Python 3.8+) is set, it will be used by pytest to cache test files changed by the assertion rewriting mechanism.

This makes it easier to benefit of cached ``.pyc`` files even on file systems without permissions.


- `5515 <https://github.com/pytest-dev/pytest/issues/5515>`_: Allow selective auto-indentation of multiline log messages.

Adds command line option ``--log-auto-indent``, config option
``log_auto_indent`` and support for per-entry configuration of
indentation behavior on calls to ``logging.log()``.

Alters the default for auto-indention from ``on`` to ``off``. This
restores the older behavior that existed prior to v4.6.0. This
reversion to earlier behavior was done because it is better to
activate new features that may lead to broken tests explicitly
rather than implicitly.


- `5914 <https://github.com/pytest-dev/pytest/issues/5914>`_: ``pytester`` learned two new functions, `no_fnmatch_line <https://docs.pytest.org/en/latest/reference.html_pytest.pytester.LineMatcher.no_fnmatch_line>`_ and
`no_re_match_line <https://docs.pytest.org/en/latest/reference.html_pytest.pytester.LineMatcher.no_re_match_line>`_.

The functions are used to ensure the captured text *does not* match the given
pattern.

The previous idiom was to use ``re.match``:

.. code-block:: python

   assert re.match(pat, result.stdout.str()) is None

Or the ``in`` operator:

.. code-block:: python

   assert text in result.stdout.str()

But the new functions produce best output on failure.


- `6057 <https://github.com/pytest-dev/pytest/issues/6057>`_: Added tolerances to complex values when printing ``pytest.approx``.

For example, ``repr(pytest.approx(3+4j))`` returns ``(3+4j) ± 5e-06 ∠ ±180°``. This is polar notation indicating a circle around the expected value, with a radius of 5e-06. For ``approx`` comparisons to return ``True``, the actual value should fall within this circle.


- `6061 <https://github.com/pytest-dev/pytest/issues/6061>`_: Added the pluginmanager as an argument to ``pytest_addoption``
so that hooks can be invoked when setting up command line options. This is
useful for having one plugin communicate things to another plugin,
such as default values or which set of command line options to add.



Improvements
------------

- `5061 <https://github.com/pytest-dev/pytest/issues/5061>`_: Use multiple colors with terminal summary statistics.


- `5630 <https://github.com/pytest-dev/pytest/issues/5630>`_: Quitting from debuggers is now properly handled in ``doctest`` items.


- `5924 <https://github.com/pytest-dev/pytest/issues/5924>`_: Improved verbose diff output with sequences.

Before:

.. code-block::

   E   AssertionError: assert ['version', '...version_info'] == ['version', '...version', ...]
   E     Right contains 3 more items, first extra item: ' '
   E     Full diff:
   E     - ['version', 'version_info', 'sys.version', 'sys.version_info']
   E     + ['version',
   E     +  'version_info',
   E     +  'sys.version',
   E     +  'sys.version_info',
   E     +  ' ',
   E     +  'sys.version',
   E     +  'sys.version_info']

After:

.. code-block::

   E   AssertionError: assert ['version', '...version_info'] == ['version', '...version', ...]
   E     Right contains 3 more items, first extra item: ' '
   E     Full diff:
   E       [
   E        'version',
   E        'version_info',
   E        'sys.version',
   E        'sys.version_info',
   E     +  ' ',
   E     +  'sys.version',
   E     +  'sys.version_info',
   E       ]


- `5936 <https://github.com/pytest-dev/pytest/issues/5936>`_: Display untruncated assertion message with ``-vv``.


- `5990 <https://github.com/pytest-dev/pytest/issues/5990>`_: Fixed plurality mismatch in test summary (e.g. display "1 error" instead of "1 errors").


- `6008 <https://github.com/pytest-dev/pytest/issues/6008>`_: ``Config.InvocationParams.args`` is now always a ``tuple`` to better convey that it should be
immutable and avoid accidental modifications.


- `6023 <https://github.com/pytest-dev/pytest/issues/6023>`_: ``pytest.main`` now returns a ``pytest.ExitCode`` instance now, except for when custom exit codes are used (where it returns ``int`` then still).


- `6026 <https://github.com/pytest-dev/pytest/issues/6026>`_: Align prefixes in output of pytester's ``LineMatcher``.


- `6059 <https://github.com/pytest-dev/pytest/issues/6059>`_: Collection errors are reported as errors (and not failures like before) in the terminal's short test summary.


- `6069 <https://github.com/pytest-dev/pytest/issues/6069>`_: ``pytester.spawn`` does not skip/xfail tests on FreeBSD anymore unconditionally.


- `6097 <https://github.com/pytest-dev/pytest/issues/6097>`_: The "[XXX%]" indicator in the test summary is now colored according to the final (new) multi-colored line's main color.


- `6116 <https://github.com/pytest-dev/pytest/issues/6116>`_: Added ``--co`` as a synonym to ``--collect-only``.


- `6148 <https://github.com/pytest-dev/pytest/issues/6148>`_: ``atomicwrites`` is now only used on Windows, fixing a performance regression with assertion rewriting on Unix.


- `6152 <https://github.com/pytest-dev/pytest/issues/6152>`_: Now parametrization will use the ``__name__`` attribute of any object for the id, if present. Previously it would only use ``__name__`` for functions and classes.


- `6176 <https://github.com/pytest-dev/pytest/issues/6176>`_: Improved failure reporting with pytester's ``Hookrecorder.assertoutcome``.


- `6181 <https://github.com/pytest-dev/pytest/issues/6181>`_: The reason for a stopped session, e.g. with ``--maxfail`` / ``-x``, now gets reported in the test summary.


- `6206 <https://github.com/pytest-dev/pytest/issues/6206>`_: Improved ``cache.set`` robustness and performance.



Bug Fixes
---------

- `2049 <https://github.com/pytest-dev/pytest/issues/2049>`_: Fixed ``--setup-plan`` showing inaccurate information about fixture lifetimes.


- `2548 <https://github.com/pytest-dev/pytest/issues/2548>`_: Fixed line offset mismatch of skipped tests in terminal summary.


- `6039 <https://github.com/pytest-dev/pytest/issues/6039>`_: The ``PytestDoctestRunner`` is now properly invalidated when unconfiguring the doctest plugin.

This is important when used with ``pytester``'s ``runpytest_inprocess``.


- `6047 <https://github.com/pytest-dev/pytest/issues/6047>`_: BaseExceptions are now handled in ``saferepr``, which includes ``pytest.fail.Exception`` etc.


- `6074 <https://github.com/pytest-dev/pytest/issues/6074>`_: pytester: fixed order of arguments in ``rm_rf`` warning when cleaning up temporary directories, and do not emit warnings for errors with ``os.open``.


- `6189 <https://github.com/pytest-dev/pytest/issues/6189>`_: Fixed result of ``getmodpath`` method.



Trivial/Internal Changes
------------------------

- `4901 <https://github.com/pytest-dev/pytest/issues/4901>`_: ``RunResult`` from ``pytester`` now displays the mnemonic of the ``ret`` attribute when it is a
valid ``pytest.ExitCode`` value.

also lol we don't even actually fucking use pytest, maybe should do that at some point so the tests can be run outside of Cirrus CI...
