Update pytest to 3.6.0

[pyup-bot]

This PR updates pytest from 3.2.1 to 3.6.0.

Changelog

3.6.0

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

Features
--------

- Revamp the internals of the ``pytest.mark`` implementation with correct per
node handling which fixes a number of long standing bugs caused by the old
design. This introduces new ``Node.iter_markers(name)`` and
``Node.get_closest_mark(name)`` APIs. Users are **strongly encouraged** to
read the `reasons for the revamp in the docs
<https://docs.pytest.org/en/latest/mark.htmlmarker-revamp-and-iteration>`_,
or jump over to details about `updating existing code to use the new APIs
<https://docs.pytest.org/en/latest/mark.htmlupdating-code>`_. (`3317
<https://github.com/pytest-dev/pytest/issues/3317>`_)

- Now when ``pytest.fixture`` is applied more than once to the same function a
``ValueError`` is raised. This buggy behavior would cause surprising problems
and if was working for a test suite it was mostly by accident. (`2334
<https://github.com/pytest-dev/pytest/issues/2334>`_)

- Support for Python 3.7's builtin ``breakpoint()`` method, see `Using the
builtin breakpoint function
<https://docs.pytest.org/en/latest/usage.htmlbreakpoint-builtin>`_ for
details. (`3180 <https://github.com/pytest-dev/pytest/issues/3180>`_)

- ``monkeypatch`` now supports a ``context()`` function which acts as a context
manager which undoes all patching done within the ``with`` block. (`3290
<https://github.com/pytest-dev/pytest/issues/3290>`_)

- The ``--pdb`` option now causes KeyboardInterrupt to enter the debugger,
instead of stopping the test session. On python 2.7, hitting CTRL+C again
exits the debugger. On python 3.2 and higher, use CTRL+D. (`3299
<https://github.com/pytest-dev/pytest/issues/3299>`_)

- pytest not longer changes the log level of the root logger when the
``log-level`` parameter has greater numeric value than that of the level of
the root logger, which makes it play better with custom logging configuration
in user code. (`3307 <https://github.com/pytest-dev/pytest/issues/3307>`_)


Bug Fixes
---------

- A rare race-condition which might result in corrupted ``.pyc`` files on
Windows has been hopefully solved. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)

- Also use iter_marker for discovering the marks applying for marker
expressions from the cli to avoid the bad data from the legacy mark storage.
(`3441 <https://github.com/pytest-dev/pytest/issues/3441>`_)

- When showing diffs of failed assertions where the contents contain only
whitespace, escape them using ``repr()`` first to make it easy to spot the
differences. (`3443 <https://github.com/pytest-dev/pytest/issues/3443>`_)


Improved Documentation
----------------------

- Change documentation copyright year to a range which auto-updates itself each
time it is published. (`3303
<https://github.com/pytest-dev/pytest/issues/3303>`_)


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

- ``pytest`` now depends on the `python-atomicwrites
<https://github.com/untitaker/python-atomicwrites>`_ library. (`3008
<https://github.com/pytest-dev/pytest/issues/3008>`_)

- Update all pypi.python.org URLs to pypi.org. (`3431
<https://github.com/pytest-dev/pytest/issues/3431>`_)

- Detect `pytest_` prefixed hooks using the internal plugin manager since
``pluggy`` is deprecating the ``implprefix`` argument to ``PluginManager``.
(`3487 <https://github.com/pytest-dev/pytest/issues/3487>`_)

- Import ``Mapping`` and ``Sequence`` from ``_pytest.compat`` instead of
directly from ``collections`` in ``python_api.py::approx``. Add ``Mapping``
to ``_pytest.compat``, import it from ``collections`` on python 2, but from
``collections.abc`` on Python 3 to avoid a ``DeprecationWarning`` on Python
3.7 or newer. (`3497 <https://github.com/pytest-dev/pytest/issues/3497>`_)

3.5.1

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


Bug Fixes
---------

- Reset ``sys.last_type``, ``sys.last_value`` and ``sys.last_traceback`` before
each test executes. Those attributes are added by pytest during the test run
to aid debugging, but were never reset so they would create a leaking
reference to the last failing test's frame which in turn could never be
reclaimed by the garbage collector. (`2798
<https://github.com/pytest-dev/pytest/issues/2798>`_)

- ``pytest.raises`` now raises ``TypeError`` when receiving an unknown keyword
argument. (`3348 <https://github.com/pytest-dev/pytest/issues/3348>`_)

- ``pytest.raises`` now works with exception classes that look like iterables.
(`3372 <https://github.com/pytest-dev/pytest/issues/3372>`_)


Improved Documentation
----------------------

- Fix typo in ``caplog`` fixture documentation, which incorrectly identified
certain attributes as methods. (`3406
<https://github.com/pytest-dev/pytest/issues/3406>`_)


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

- Added a more indicative error message when parametrizing a function whose
argument takes a default value. (`3221
<https://github.com/pytest-dev/pytest/issues/3221>`_)

- Remove internal ``_pytest.terminal.flatten`` function in favor of
``more_itertools.collapse``. (`3330
<https://github.com/pytest-dev/pytest/issues/3330>`_)

- Import some modules from ``collections.abc`` instead of ``collections`` as
the former modules trigger ``DeprecationWarning`` in Python 3.7. (`3339
<https://github.com/pytest-dev/pytest/issues/3339>`_)

- record_property is no longer experimental, removing the warnings was
forgotten. (`3360 <https://github.com/pytest-dev/pytest/issues/3360>`_)

- Mention in documentation and CLI help that fixtures with leading ``_`` are
printed by ``pytest --fixtures`` only if the ``-v`` option is added. (`3398
<https://github.com/pytest-dev/pytest/issues/3398>`_)

3.5.0

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

Deprecations and Removals
-------------------------

- ``record_xml_property`` fixture is now deprecated in favor of the more
generic ``record_property``. (`2770
<https://github.com/pytest-dev/pytest/issues/2770>`_)

- Defining ``pytest_plugins`` is now deprecated in non-top-level conftest.py
files, because they "leak" to the entire directory tree. (`3084
<https://github.com/pytest-dev/pytest/issues/3084>`_)


Features
--------

- New ``--show-capture`` command-line option that allows to specify how to
display captured output when tests fail: ``no``, ``stdout``, ``stderr``,
``log`` or ``all`` (the default). (`1478
<https://github.com/pytest-dev/pytest/issues/1478>`_)

- New ``--rootdir`` command-line option to override the rules for discovering
the root directory. See `customize
<https://docs.pytest.org/en/latest/customize.html>`_ in the documentation for
details. (`1642 <https://github.com/pytest-dev/pytest/issues/1642>`_)

- Fixtures are now instantiated based on their scopes, with higher-scoped
fixtures (such as ``session``) being instantiated first than lower-scoped
fixtures (such as ``function``). The relative order of fixtures of the same
scope is kept unchanged, based in their declaration order and their
dependencies. (`2405 <https://github.com/pytest-dev/pytest/issues/2405>`_)

- ``record_xml_property`` renamed to ``record_property`` and is now compatible
with xdist, markers and any reporter. ``record_xml_property`` name is now
deprecated. (`2770 <https://github.com/pytest-dev/pytest/issues/2770>`_)

- New ``--nf``, ``--new-first`` options: run new tests first followed by the
rest of the tests, in both cases tests are also sorted by the file modified
time, with more recent files coming first. (`3034
<https://github.com/pytest-dev/pytest/issues/3034>`_)

- New ``--last-failed-no-failures`` command-line option that allows to specify
the behavior of the cache plugin's --last-failed`` feature when no tests
failed in the last run (or no cache was found): ``none`` or ``all`` (the
default). (`3139 <https://github.com/pytest-dev/pytest/issues/3139>`_)

- New ``--doctest-continue-on-failure`` command-line option to enable doctests
to show multiple failures for each snippet, instead of stopping at the first
failure. (`3149 <https://github.com/pytest-dev/pytest/issues/3149>`_)

- Captured log messages are added to the ``<system-out>`` tag in the generated
junit xml file if the ``junit_logging`` ini option is set to ``system-out``.
If the value of this ini option is ``system-err``, the logs are written to
``<system-err>``. The default value for ``junit_logging`` is ``no``, meaning
captured logs are not written to the output file. (`3156
<https://github.com/pytest-dev/pytest/issues/3156>`_)

- Allow the logging plugin to handle ``pytest_runtest_logstart`` and
``pytest_runtest_logfinish`` hooks when live logs are enabled. (`3189
<https://github.com/pytest-dev/pytest/issues/3189>`_)

- Passing `--log-cli-level` in the command-line now automatically activates
live logging. (`3190 <https://github.com/pytest-dev/pytest/issues/3190>`_)

- Add command line option ``--deselect`` to allow deselection of individual
tests at collection time. (`3198
<https://github.com/pytest-dev/pytest/issues/3198>`_)

- Captured logs are printed before entering pdb. (`3204
<https://github.com/pytest-dev/pytest/issues/3204>`_)

- Deselected item count is now shown before tests are run, e.g. ``collected X
items / Y deselected``. (`3213
<https://github.com/pytest-dev/pytest/issues/3213>`_)

- The builtin module ``platform`` is now available for use in expressions in
``pytest.mark``. (`3236
<https://github.com/pytest-dev/pytest/issues/3236>`_)

- The *short test summary info* section now is displayed after tracebacks and
warnings in the terminal. (`3255
<https://github.com/pytest-dev/pytest/issues/3255>`_)

- New ``--verbosity`` flag to set verbosity level explicitly. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)

- ``pytest.approx`` now accepts comparing a numpy array with a scalar. (`3312
<https://github.com/pytest-dev/pytest/issues/3312>`_)


Bug Fixes
---------

- Suppress ``IOError`` when closing the temporary file used for capturing
streams in Python 2.7. (`2370
<https://github.com/pytest-dev/pytest/issues/2370>`_)

- Fixed ``clear()`` method on ``caplog`` fixture which cleared ``records``, but
not the ``text`` property. (`3297
<https://github.com/pytest-dev/pytest/issues/3297>`_)

- During test collection, when stdin is not allowed to be read, the
``DontReadFromStdin`` object still allow itself to be iterable and resolved
to an iterator without crashing. (`3314
<https://github.com/pytest-dev/pytest/issues/3314>`_)


Improved Documentation
----------------------

- Added a `reference <https://docs.pytest.org/en/latest/reference.html>`_ page
to the docs. (`1713 <https://github.com/pytest-dev/pytest/issues/1713>`_)


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

- Change minimum requirement of ``attrs`` to ``17.4.0``. (`3228
<https://github.com/pytest-dev/pytest/issues/3228>`_)

- Renamed example directories so all tests pass when ran from the base
directory. (`3245 <https://github.com/pytest-dev/pytest/issues/3245>`_)

- Internal ``mark.py`` module has been turned into a package. (`3250
<https://github.com/pytest-dev/pytest/issues/3250>`_)

- ``pytest`` now depends on the `more-itertools
<https://github.com/erikrose/more-itertools>`_ package. (`3265
<https://github.com/pytest-dev/pytest/issues/3265>`_)

- Added warning when ``[pytest]`` section is used in a ``.cfg`` file passed
with ``-c`` (`3268 <https://github.com/pytest-dev/pytest/issues/3268>`_)

- ``nodeids`` can now be passed explicitly to ``FSCollector`` and ``Node``
constructors. (`3291 <https://github.com/pytest-dev/pytest/issues/3291>`_)

- Internal refactoring of ``FormattedExcinfo`` to use ``attrs`` facilities and
remove old support code for legacy Python versions. (`3292
<https://github.com/pytest-dev/pytest/issues/3292>`_)

- Refactoring to unify how verbosity is handled internally. (`3296
<https://github.com/pytest-dev/pytest/issues/3296>`_)

- Internal refactoring to better integrate with argparse. (`3304
<https://github.com/pytest-dev/pytest/issues/3304>`_)

- Fix a python example when calling a fixture in doc/en/usage.rst (`3308
<https://github.com/pytest-dev/pytest/issues/3308>`_)

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

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>`_)

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>`_)

<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>`_)

<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

- 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>`_)

- 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>`_)
