3.10.0

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

Features
--------

- `2619 <https://github.com/pytest-dev/pytest/issues/2619>`_: Resume capturing output after ``continue`` with ``__import__("pdb").set_trace()``.

This also adds a new ``pytest_leave_pdb`` hook, and passes in ``pdb`` to the
existing ``pytest_enter_pdb`` hook.


- `4147 <https://github.com/pytest-dev/pytest/issues/4147>`_: Add ``--sw``, ``--stepwise`` as an alternative to ``--lf -x`` for stopping at the first failure, but starting the next test invocation from that test.  See `the documentation <https://docs.pytest.org/en/latest/cache.htmlstepwise>`__ for more info.


- `4188 <https://github.com/pytest-dev/pytest/issues/4188>`_: Make ``--color`` emit colorful dots when not running in verbose mode. Earlier, it would only colorize the test-by-test output if ``--verbose`` was also passed.


- `4225 <https://github.com/pytest-dev/pytest/issues/4225>`_: Improve performance with collection reporting in non-quiet mode with terminals.

The "collecting …" message is only printed/updated every 0.5s.

- `611 <https://github.com/pytest-dev/pytest/issues/611>`_: Naming a fixture ``request`` will now raise a warning: the ``request`` fixture is internal and
should not be overwritten as it will lead to internal errors.

- `4266 <https://github.com/pytest-dev/pytest/issues/4266>`_: Handle (ignore) exceptions raised during collection, e.g. with Django's LazySettings proxy class.



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

- `4255 <https://github.com/pytest-dev/pytest/issues/4255>`_: Added missing documentation about the fact that module names passed to filter warnings are not regex-escaped.



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

- `4272 <https://github.com/pytest-dev/pytest/issues/4272>`_: Display cachedir also in non-verbose mode if non-default.


- `4277 <https://github.com/pytest-dev/pytest/issues/4277>`_: pdb: improve message about output capturing with ``set_trace``.

Do not display "IO-capturing turned off/on" when ``-s`` is used to avoid
confusion.


- `4279 <https://github.com/pytest-dev/pytest/issues/4279>`_: Improve message and stack level of warnings issued by ``monkeypatch.setenv`` when the value of the environment variable is not a ``str``.

- `4243 <https://github.com/pytest-dev/pytest/issues/4243>`_: Fix regression when ``stacklevel`` for warnings was passed as positional argument on python2.



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

- `3851 <https://github.com/pytest-dev/pytest/issues/3851>`_: Add reference to ``empty_parameter_set_mark`` ini option in documentation of ``pytest.mark.parametrize``



Trivial/Internal Changes

- `3340 <https://github.com/pytest-dev/pytest/issues/3340>`_: Fix logging messages not shown in hooks ``pytest_sessionstart()`` and ``pytest_sessionfinish()``.


- `3533 <https://github.com/pytest-dev/pytest/issues/3533>`_: Fix unescaped XML raw objects in JUnit report for skipped tests


- `3691 <https://github.com/pytest-dev/pytest/issues/3691>`_: Python 2: safely format warning message about passing unicode strings to ``warnings.warn``, which may cause
surprising ``MemoryError`` exception when monkey patching ``warnings.warn`` itself.

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

Features
--------

- `4159 <https://github.com/pytest-dev/pytest/issues/4159>`_: For test-suites containing test classes, the information about the subclassed
module is now output only if a higher verbosity level is specified (at least
"-vv").

3.9.0

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

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

- `3616 <https://github.com/pytest-dev/pytest/issues/3616>`_: The following accesses have been documented as deprecated for years, but are now actually emitting deprecation warnings.

* Access of ``Module``, ``Function``, ``Class``, ``Instance``, ``File`` and ``Item`` through ``Node`` instances. Now
 users will this warning::

       usage of Function.Module is deprecated, please use pytest.Module instead

 Users should just ``import pytest`` and access those objects using the ``pytest`` module.

* ``request.cached_setup``, this was the precursor of the setup/teardown mechanism available to fixtures. You can
 consult `funcarg comparison section in the docs <https://docs.pytest.org/en/latest/funcarg_compare.html>`_.

* Using objects named ``"Class"`` as a way to customize the type of nodes that are collected in ``Collector``
 subclasses has been deprecated. Users instead should use ``pytest_collect_make_item`` to customize node types during
 collection.

 This issue should affect only advanced plugins who create new collection types, so if you see this warning
 message please contact the authors so they can change the code.

* The warning that produces the message below has changed to ``RemovedInPytest4Warning``::

       getfuncargvalue is deprecated, use getfixturevalue


- `3988 <https://github.com/pytest-dev/pytest/issues/3988>`_: Add a Deprecation warning for pytest.ensuretemp as it was deprecated since a while.



Features
--------

- `2293 <https://github.com/pytest-dev/pytest/issues/2293>`_: Improve usage errors messages by hiding internal details which can be distracting and noisy.

This has the side effect that some error conditions that previously raised generic errors (such as
``ValueError`` for unregistered marks) are now raising ``Failed`` exceptions.


- `3332 <https://github.com/pytest-dev/pytest/issues/3332>`_: Improve the error displayed when a ``conftest.py`` file could not be imported.

In order to implement this, a new ``chain`` parameter was added to ``ExceptionInfo.getrepr``
to show or hide chained tracebacks in Python 3 (defaults to ``True``).


- `3849 <https://github.com/pytest-dev/pytest/issues/3849>`_: Add ``empty_parameter_set_mark=fail_at_collect`` ini option for raising an exception when parametrize collects an empty set.


- `3964 <https://github.com/pytest-dev/pytest/issues/3964>`_: Log messages generated in the collection phase are shown when
live-logging is enabled and/or when they are logged to a file.


- `3985 <https://github.com/pytest-dev/pytest/issues/3985>`_: Introduce ``tmp_path`` as a fixture providing a Path object.


- `4013 <https://github.com/pytest-dev/pytest/issues/4013>`_: Deprecation warnings are now shown even if you customize the warnings filters yourself. In the previous version
any customization would override pytest's filters and deprecation warnings would fall back to being hidden by default.


- `4073 <https://github.com/pytest-dev/pytest/issues/4073>`_: Allow specification of timeout for ``Testdir.runpytest_subprocess()`` and ``Testdir.run()``.


- `4098 <https://github.com/pytest-dev/pytest/issues/4098>`_: Add returncode argument to pytest.exit() to exit pytest with a specific return code.


- `4102 <https://github.com/pytest-dev/pytest/issues/4102>`_: Reimplement ``pytest.deprecated_call`` using ``pytest.warns`` so it supports the ``match='...'`` keyword argument.

This has the side effect that ``pytest.deprecated_call`` now raises ``pytest.fail.Exception`` instead
of ``AssertionError``.


- `4149 <https://github.com/pytest-dev/pytest/issues/4149>`_: Require setuptools>=30.3 and move most of the metadata to ``setup.cfg``.



Bug Fixes
---------

- `2535 <https://github.com/pytest-dev/pytest/issues/2535>`_: Improve error message when test functions of ``unittest.TestCase`` subclasses use a parametrized fixture.


- `3057 <https://github.com/pytest-dev/pytest/issues/3057>`_: ``request.fixturenames`` now correctly returns the name of fixtures created by ``request.getfixturevalue()``.


- `3946 <https://github.com/pytest-dev/pytest/issues/3946>`_: Warning filters passed as command line options using ``-W`` now take precedence over filters defined in ``ini``
configuration files.


- `4066 <https://github.com/pytest-dev/pytest/issues/4066>`_: Fix source reindenting by using ``textwrap.dedent`` directly.


- `4102 <https://github.com/pytest-dev/pytest/issues/4102>`_: ``pytest.warn`` will capture previously-warned warnings in Python 2. Previously they were never raised.


- `4108 <https://github.com/pytest-dev/pytest/issues/4108>`_: Resolve symbolic links for args.

This fixes running ``pytest tests/test_foo.py::test_bar``, where ``tests``
is a symlink to ``project/app/tests``:
previously ``project/app/conftest.py`` would be ignored for fixtures then.


- `4132 <https://github.com/pytest-dev/pytest/issues/4132>`_: Fix duplicate printing of internal errors when using ``--pdb``.


- `4135 <https://github.com/pytest-dev/pytest/issues/4135>`_: pathlib based tmpdir cleanup now correctly handles symlinks in the folder.


- `4152 <https://github.com/pytest-dev/pytest/issues/4152>`_: Display the filename when encountering ``SyntaxWarning``.



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

- `3713 <https://github.com/pytest-dev/pytest/issues/3713>`_: Update usefixtures documentation to clarify that it can't be used with fixture functions.


- `4058 <https://github.com/pytest-dev/pytest/issues/4058>`_: Update fixture documentation to specify that a fixture can be invoked twice in the scope it's defined for.


- `4064 <https://github.com/pytest-dev/pytest/issues/4064>`_: According to unittest.rst, setUpModule and tearDownModule were not implemented, but it turns out they are. So updated the documentation for unittest.


- `4151 <https://github.com/pytest-dev/pytest/issues/4151>`_: Add tempir testing example to CONTRIBUTING.rst guide



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

- `2293 <https://github.com/pytest-dev/pytest/issues/2293>`_: The internal ``MarkerError`` exception has been removed.


- `3988 <https://github.com/pytest-dev/pytest/issues/3988>`_: Port the implementation of tmpdir to pathlib.


- `4063 <https://github.com/pytest-dev/pytest/issues/4063>`_: Exclude 0.00 second entries from ``--duration`` output unless ``-vv`` is passed on the command-line.


- `4093 <https://github.com/pytest-dev/pytest/issues/4093>`_: Fixed formatting of string literals in internal tests.

3.8.2

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

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

- `4036 <https://github.com/pytest-dev/pytest/issues/4036>`_: The ``item`` parameter of ``pytest_warning_captured`` hook is now documented as deprecated. We realized only after
the ``3.8`` release that this parameter is incompatible with ``pytest-xdist``.

Our policy is to not deprecate features during bugfix releases, but in this case we believe it makes sense as we are
only documenting it as deprecated, without issuing warnings which might potentially break test suites. This will get
the word out that hook implementers should not use this parameter at all.

In a future release ``item`` will always be ``None`` and will emit a proper warning when a hook implementation
makes use of it.



Bug Fixes
---------

- `3539 <https://github.com/pytest-dev/pytest/issues/3539>`_: Fix reload on assertion rewritten modules.


- `4034 <https://github.com/pytest-dev/pytest/issues/4034>`_: The ``.user_properties`` attribute of ``TestReport`` objects is a list
of (name, value) tuples, but could sometimes be instantiated as a tuple
of tuples.  It is now always a list.


- `4039 <https://github.com/pytest-dev/pytest/issues/4039>`_: No longer issue warnings about using ``pytest_plugins`` in non-top-level directories when using ``--pyargs``: the
current ``--pyargs`` mechanism is not reliable and might give false negatives.


- `4040 <https://github.com/pytest-dev/pytest/issues/4040>`_: Exclude empty reports for passed tests when ``-rP`` option is used.


- `4051 <https://github.com/pytest-dev/pytest/issues/4051>`_: Improve error message when an invalid Python expression is passed to the ``-m`` option.


- `4056 <https://github.com/pytest-dev/pytest/issues/4056>`_: ``MonkeyPatch.setenv`` and ``MonkeyPatch.delenv`` issue a warning if the environment variable name is not ``str`` on Python 2.

In Python 2, adding ``unicode`` keys to ``os.environ`` causes problems with ``subprocess`` (and possible other modules),
making this a subtle bug specially susceptible when used with ``from __future__ import unicode_literals``.



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

- `3928 <https://github.com/pytest-dev/pytest/issues/3928>`_: Add possible values for fixture scope to docs.

3.8.1

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

Bug Fixes
---------

- `3286 <https://github.com/pytest-dev/pytest/issues/3286>`_: ``.pytest_cache`` directory is now automatically ignored by Git. Users who would like to contribute a solution for other SCMs please consult/comment on this issue.


- `3749 <https://github.com/pytest-dev/pytest/issues/3749>`_: Fix the following error during collection of tests inside packages::

   TypeError: object of type 'Package' has no len()


- `3941 <https://github.com/pytest-dev/pytest/issues/3941>`_: Fix bug where indirect parametrization would consider the scope of all fixtures used by the test function to determine the parametrization scope, and not only the scope of the fixtures being parametrized.


- `3973 <https://github.com/pytest-dev/pytest/issues/3973>`_: Fix crash of the assertion rewriter if a test changed the current working directory without restoring it afterwards.


- `3998 <https://github.com/pytest-dev/pytest/issues/3998>`_: Fix issue that prevented some caplog properties (for example ``record_tuples``) from being available when entering the debugger with ``--pdb``.


- `3999 <https://github.com/pytest-dev/pytest/issues/3999>`_: Fix ``UnicodeDecodeError`` in python2.x when a class returns a non-ascii binary ``__repr__`` in an assertion which also contains non-ascii text.



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

- `3996 <https://github.com/pytest-dev/pytest/issues/3996>`_: New `Deprecations and Removals <https://docs.pytest.org/en/latest/deprecations.html>`_ page shows all currently
deprecated features, the rationale to do so, and alternatives to update your code. It also list features removed
from pytest in past major releases to help those with ancient pytest versions to upgrade.



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

- `3955 <https://github.com/pytest-dev/pytest/issues/3955>`_: Improve pre-commit detection for changelog filenames


- `3975 <https://github.com/pytest-dev/pytest/issues/3975>`_: Remove legacy code around im_func as that was python2 only

3.8.0

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

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

- `2452 <https://github.com/pytest-dev/pytest/issues/2452>`_: ``Config.warn`` and ``Node.warn`` have been
deprecated, see `<https://docs.pytest.org/en/latest/deprecations.htmlconfig-warn-and-node-warn>`_ for rationale and
examples.

- `3936 <https://github.com/pytest-dev/pytest/issues/3936>`_: ``pytest.mark.filterwarnings`` second parameter is no longer regex-escaped,
making it possible to actually use regular expressions to check the warning message.

**Note**: regex-escaping the match string was an implementation oversight that might break test suites which depend
on the old behavior.



Features
--------

- `2452 <https://github.com/pytest-dev/pytest/issues/2452>`_: Internal pytest warnings are now issued using the standard ``warnings`` module, making it possible to use
the standard warnings filters to manage those warnings. This introduces ``PytestWarning``,
``PytestDeprecationWarning`` and ``RemovedInPytest4Warning`` warning types as part of the public API.

Consult `the documentation <https://docs.pytest.org/en/latest/warnings.htmlinternal-pytest-warnings>`__ for more info.


- `2908 <https://github.com/pytest-dev/pytest/issues/2908>`_: ``DeprecationWarning`` and ``PendingDeprecationWarning`` are now shown by default if no other warning filter is
configured. This makes pytest more compliant with
`PEP-0506 <https://www.python.org/dev/peps/pep-0565/recommended-filter-settings-for-test-runners>`_. See
`the docs <https://docs.pytest.org/en/latest/warnings.htmldeprecationwarning-and-pendingdeprecationwarning>`_ for
more info.


- `3251 <https://github.com/pytest-dev/pytest/issues/3251>`_: Warnings are now captured and displayed during test collection.


- `3784 <https://github.com/pytest-dev/pytest/issues/3784>`_: ``PYTEST_DISABLE_PLUGIN_AUTOLOAD`` environment variable disables plugin auto-loading when set.


- `3829 <https://github.com/pytest-dev/pytest/issues/3829>`_: Added the ``count`` option to ``console_output_style`` to enable displaying the progress as a count instead of a percentage.


- `3837 <https://github.com/pytest-dev/pytest/issues/3837>`_: Added support for 'xfailed' and 'xpassed' outcomes to the ``pytester.RunResult.assert_outcomes`` signature.



Bug Fixes
---------

- `3911 <https://github.com/pytest-dev/pytest/issues/3911>`_: Terminal writer now takes into account unicode character width when writing out progress.


- `3913 <https://github.com/pytest-dev/pytest/issues/3913>`_: Pytest now returns with correct exit code (EXIT_USAGEERROR, 4) when called with unknown arguments.


- `3918 <https://github.com/pytest-dev/pytest/issues/3918>`_: Improve performance of assertion rewriting.



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

- `3566 <https://github.com/pytest-dev/pytest/issues/3566>`_: Added a blurb in usage.rst for the usage of -r flag which is used to show an extra test summary info.


- `3907 <https://github.com/pytest-dev/pytest/issues/3907>`_: Corrected type of the exceptions collection passed to ``xfail``: ``raises`` argument accepts a ``tuple`` instead of ``list``.



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

- `3853 <https://github.com/pytest-dev/pytest/issues/3853>`_: Removed ``"run all (no recorded failures)"`` message printed with ``--failed-first`` and ``--last-failed`` when there are no failed tests.

3.7.4

fixed.

3.7.2

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

Bug Fixes
---------

- `3671 <https://github.com/pytest-dev/pytest/issues/3671>`_: Fix ``filterwarnings`` not being registered as a builtin mark.


- `3768 <https://github.com/pytest-dev/pytest/issues/3768>`_, `3789 <https://github.com/pytest-dev/pytest/issues/3789>`_: Fix test collection from packages mixed with normal directories.

3.7.0

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

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

- `2639 <https://github.com/pytest-dev/pytest/issues/2639>`_: ``pytest_namespace`` has been `deprecated <https://docs.pytest.org/en/latest/deprecations.htmlpytest-namespace>`_.


- `3661 <https://github.com/pytest-dev/pytest/issues/3661>`_: Calling a fixture function directly, as opposed to request them in a test function, now issues a ``RemovedInPytest4Warning``. See `the documentation for rationale and examples <https://docs.pytest.org/en/latest/deprecations.htmlcalling-fixtures-directly>`_.



Features
--------

- `2283 <https://github.com/pytest-dev/pytest/issues/2283>`_: New ``package`` fixture scope: fixtures are finalized when the last test of a *package* finishes. This feature is considered **experimental**, so use it sparingly.


- `3576 <https://github.com/pytest-dev/pytest/issues/3576>`_: ``Node.add_marker`` now supports an ``append=True/False`` parameter to determine whether the mark comes last (default) or first.


- `3579 <https://github.com/pytest-dev/pytest/issues/3579>`_: Fixture ``caplog`` now has a ``messages`` property, providing convenient access to the format-interpolated log messages without the extra data provided by the formatter/handler.


- `3610 <https://github.com/pytest-dev/pytest/issues/3610>`_: New ``--trace`` option to enter the debugger at the start of a test.


- `3623 <https://github.com/pytest-dev/pytest/issues/3623>`_: Introduce ``pytester.copy_example`` as helper to do acceptance tests against examples from the project.

- `3695 <https://github.com/pytest-dev/pytest/issues/3695>`_: Fix ``ApproxNumpy`` initialisation argument mixup, ``abs`` and ``rel`` tolerances were flipped causing strange comparsion results.
Add tests to check ``abs`` and ``rel`` tolerances for ``np.array`` and test for expecting ``nan`` with ``np.array()``


- `980 <https://github.com/pytest-dev/pytest/issues/980>`_: Fix truncated locals output in verbose mode.



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

- `3295 <https://github.com/pytest-dev/pytest/issues/3295>`_: Correct the usage documentation of ``--last-failed-no-failures`` by adding the missing ``--last-failed`` argument in the presented examples, because they are misleading and lead to think that the missing argument is not needed.



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

- `3519 <https://github.com/pytest-dev/pytest/issues/3519>`_: Now a ``README.md`` file is created in ``.pytest_cache`` to make it clear why the directory exists.

3.6.4

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

Bug Fixes
---------

- Invoke pytest using ``-mpytest`` so ``sys.path`` does not get polluted by packages installed in ``site-packages``. (`742 <https://github.com/pytest-dev/pytest/issues/742>`_)


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

- Use ``smtp_connection`` instead of ``smtp`` in fixtures documentation to avoid possible confusion. (`3592 <https://github.com/pytest-dev/pytest/issues/3592>`_)


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

- Remove obsolete ``__future__`` imports. (`2319 <https://github.com/pytest-dev/pytest/issues/2319>`_)

- Pin ``pluggy`` to ``<0.8``. (`3727 <https://github.com/pytest-dev/pytest/issues/3727>`_)

3.6.3

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

- Fix ``ImportWarning`` triggered by explicit relative imports in
assertion-rewritten package modules. (`3061
<https://github.com/pytest-dev/pytest/issues/3061>`_)

appear in the output log file.
(`3630 <https://github.com/pytest-dev/pytest/issues/3630>`_)

- No longer raise ``AttributeError`` when legacy marks can't be stored in
functions. (`3631 <https://github.com/pytest-dev/pytest/issues/3631>`_)


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

- The description above the example for ``pytest.mark.skipif`` now better
matches the code. (`3611
<https://github.com/pytest-dev/pytest/issues/3611>`_)


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

- Internal refactoring: removed unused ``CallSpec2tox ._globalid_args``
attribute and ``metafunc`` parameter from ``CallSpec2.copy()``. (`3598
<https://github.com/pytest-dev/pytest/issues/3598>`_)

- Silence usage of ``reduce`` warning in Python 2 (`3609
<https://github.com/pytest-dev/pytest/issues/3609>`_)

<https://github.com/pytest-dev/pytest/issues/3653>`_)

3.6.2

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

Bug Fixes
---------

- Fix regression in ``Node.add_marker`` by extracting the mark object of a
``MarkDecorator``. (`3555
<https://github.com/pytest-dev/pytest/issues/3555>`_)

- Warnings without ``location`` were reported as ``None``. This is corrected to
now report ``<undetermined location>``. (`3563
<https://github.com/pytest-dev/pytest/issues/3563>`_)

- Continue to call finalizers in the stack when a finalizer in a former scope
raises an exception. (`3569
<https://github.com/pytest-dev/pytest/issues/3569>`_)

- Fix encoding error with ``print`` statements in doctests (`3583
<https://github.com/pytest-dev/pytest/issues/3583>`_)


Improved Documentation

<https://github.com/pytest-dev/pytest/issues/3549>`_)


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

<https://github.com/pytest-dev/pytest/issues/3525>`_)

- Improve display of hint about ``--fulltrace`` with ``KeyboardInterrupt``.
(`3545 <https://github.com/pytest-dev/pytest/issues/3545>`_)

- pytest's testsuite is no longer runnable through ``python setup.py test`` --
instead invoke ``pytest`` or ``tox`` directly. (`3552
<https://github.com/pytest-dev/pytest/issues/3552>`_)

- Fix typo in documentation (`3567
<https://github.com/pytest-dev/pytest/issues/3567>`_)

3.6.1

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

Bug Fixes
---------

- Fixed a bug where stdout and stderr were logged twice by junitxml when a test
was marked xfail. (`3491
<https://github.com/pytest-dev/pytest/issues/3491>`_)

- Fix ``usefixtures`` mark applyed to unittest tests by correctly instantiating
``FixtureInfo``. (`3498
<https://github.com/pytest-dev/pytest/issues/3498>`_)

- Fix assertion rewriter compatibility with libraries that monkey patch
``file`` objects. (`3503
<https://github.com/pytest-dev/pytest/issues/3503>`_)


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

- Added a section on how to use fixtures as factories to the fixture
documentation. (`3461 <https://github.com/pytest-dev/pytest/issues/3461>`_)


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

- Enable caching for pip/pre-commit in order to reduce build time on
travis/appveyor. (`3502
<https://github.com/pytest-dev/pytest/issues/3502>`_)

- Switch pytest to the src/ layout as we already suggested it for good practice
- now we implement it as well. (`3513
<https://github.com/pytest-dev/pytest/issues/3513>`_)

reverted. (`3530 <https://github.com/pytest-dev/pytest/issues/3530>`_)

- Remove some python2.5 compatibility code. (`3529
<https://github.com/pytest-dev/pytest/issues/3529>`_)

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. `See the docs <https://docs.pytest.org/en/latest/deprecations.htmlpytest-plugins-in-non-top-level-conftest-files>`_ for the rationale behind this decision (`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>`_)

------------------------

- 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>`_)

- 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>`_)

<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
