pytest 3.1.3 -> 3.2.2

3.2.2

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

Bug Fixes

• 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>_)

Trivial/Internal Changes

• Fixed minor error in 'Good Practices/Manual Integration' code snippet.
  (2691 <https://github.com/pytest-dev/pytest/issues/2691>_)

• Fixed typo in goodpractices.rst. (2721 <https://github.com/pytest-dev/pytest/issues/2721>_)

• Improve user guidance regarding --resultlog deprecation. (2739 <https://github.com/pytest-dev/pytest/issues/2739>_)

3.2.1

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

Bug Fixes

• Fixed small terminal glitch when collecting a single test item. (2579 <https://github.com/pytest-dev/pytest/issues/2579>_)

• Correctly consider / as the file separator to automatically mark plugin
  files for rewrite on Windows. (2591 <https://github.com/pytest- dev/pytest/issues/2591>_)

• Properly escape test names when setting PYTEST_CURRENT_TEST environment
  variable. (2644 <https://github.com/pytest-dev/pytest/issues/2644>_)

• Fix error on Windows and Python 3.6+ when sys.stdout has been replaced
  with a stream-like object which does not implement the full io module
  buffer protocol. In particular this affects pytest-xdist users on the
  aforementioned platform. (2666 <https://github.com/pytest- dev/pytest/issues/2666>_)

Improved Documentation

• Explicitly document which pytest features work with unittest. (2626 <https://github.com/pytest-dev/pytest/issues/2626>_)

3.2.0

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

Deprecations and Removals

• pytest.approx no longer supports >, >=, < and <=
  operators to avoid surprising/inconsistent behavior. See the docs <https://docs.pytest.org/en/latest/builtin.htmlpytest.approx>_ for more
  information. (2003 <https://github.com/pytest-dev/pytest/issues/2003>_)

• All old-style specific behavior in current classes in the pytest's API is
  considered deprecated at this point and will be removed in a future release.
  This affects Python 2 users only and in rare situations. (2147 <https://github.com/pytest-dev/pytest/issues/2147>_)

• A deprecation warning is now raised when using marks for parameters
  in pytest.mark.parametrize. Use pytest.param to apply marks to
  parameters instead. (2427 <https://github.com/pytest-dev/pytest/issues/2427>_)

Features

• Add support for numpy arrays (and dicts) to approx. (1994 <https://github.com/pytest-dev/pytest/issues/1994>_)

• Now test function objects have a pytestmark attribute containing a list
  of marks applied directly to the test function, as opposed to marks inherited
  from parent classes or modules. (2516 <https://github.com/pytest- dev/pytest/issues/2516>_)

• Collection ignores local virtualenvs by default; --collect-in-virtualenv
  overrides this behavior. (2518 <https://github.com/pytest- dev/pytest/issues/2518>_)

• Allow class methods decorated as staticmethod to be candidates for
  collection as a test function. (Only for Python 2.7 and above. Python 2.6
  will still ignore static methods.) (2528 <https://github.com/pytest- dev/pytest/issues/2528>_)

• Introduce mark.with_args in order to allow passing functions/classes as
  sole argument to marks. (2540 <https://github.com/pytest- dev/pytest/issues/2540>_)

• New cache_dir ini option: sets the directory where the contents of the
  cache plugin are stored. Directory may be relative or absolute path: if relative path, then
  directory is created relative to rootdir, otherwise it is used as is.
  Additionally path may contain environment variables which are expanded during
  runtime. (2543 <https://github.com/pytest-dev/pytest/issues/2543>_)

• Introduce the PYTEST_CURRENT_TEST environment variable that is set with
  the nodeid and stage (setup, call and teardown) of the test
  being currently executed. See the documentation <https://docs.pytest.org/en/latest/example/simple.htmlpytest-current-test- environment-variable>_ for more info. (2583 <https://github.com/pytest- dev/pytest/issues/2583>_)

• Introduced pytest.mark.filterwarnings mark which allows overwriting the
  warnings filter on a per test, class or module level. See the docs <https://docs.pytest.org/en/latest/warnings.htmlpytest-mark- filterwarnings>_ for more information. (2598 <https://github.com/pytest- dev/pytest/issues/2598>_)

• --last-failed now remembers forever when a test has failed and only
  forgets it if it passes again. This makes it easy to fix a test suite by
  selectively running files and fixing tests incrementally. (2621 <https://github.com/pytest-dev/pytest/issues/2621>_)

• New pytest_report_collectionfinish hook which allows plugins to add
  messages to the terminal reporting after collection has been finished
  successfully. (2622 <https://github.com/pytest-dev/pytest/issues/2622>_)

• Added support for PEP-415's <https://www.python.org/dev/peps/pep-0415/>_
  Exception.__suppress_context__. Now if a raise exception from None is
  caught by pytest, pytest will no longer chain the context in the test report.
  The behavior now matches Python's traceback behavior. (2631 <https://github.com/pytest-dev/pytest/issues/2631>_)

• Exceptions raised by pytest.fail, pytest.skip and pytest.xfail
  now subclass BaseException, making them harder to be caught unintentionally
  by normal code. (580 <https://github.com/pytest-dev/pytest/issues/580>_)

Bug Fixes

• Set stdin to a closed PIPE in pytester.py.Testdir.popen() for
  avoid unwanted interactive pdb (2023 <https://github.com/pytest- dev/pytest/issues/2023>_)

• Add missing encoding attribute to sys.std* streams when using
  capsys capture mode. (2375 <https://github.com/pytest- dev/pytest/issues/2375>_)

• Fix terminal color changing to black on Windows if colorama is imported
  in a conftest.py file. (2510 <https://github.com/pytest- dev/pytest/issues/2510>_)

• Fix line number when reporting summary of skipped tests. (2548 <https://github.com/pytest-dev/pytest/issues/2548>_)

• capture: ensure that EncodedFile.name is a string. (2555 <https://github.com/pytest-dev/pytest/issues/2555>_)

• The options --fixtures and --fixtures-per-test will now keep
  indentation within docstrings. (2574 <https://github.com/pytest- dev/pytest/issues/2574>_)

• doctests line numbers are now reported correctly, fixing pytest-sugar122 <https://github.com/Frozenball/pytest-sugar/issues/122>. (2610 <https://github.com/pytest-dev/pytest/issues/2610>)

• Fix non-determinism in order of fixture collection. Adds new dependency
  (ordereddict) for Python 2.6. (920 <https://github.com/pytest- dev/pytest/issues/920>_)

Improved Documentation

• Clarify pytest_configure hook call order. (2539 <https://github.com/pytest-dev/pytest/issues/2539>_)

• Extend documentation for testing plugin code with the pytester plugin.
  (971 <https://github.com/pytest-dev/pytest/issues/971>_)

Trivial/Internal Changes

• Update help message for --strict to make it clear it only deals with
  unregistered markers, not warnings. (2444 <https://github.com/pytest- dev/pytest/issues/2444>_)

• Internal code move: move code for pytest.approx/pytest.raises to own files in
  order to cut down the size of python.py (2489 <https://github.com/pytest- dev/pytest/issues/2489>_)

• Renamed the utility function _pytest.compat._escape_strings to
  _ascii_escaped to better communicate the function's purpose. (2533 <https://github.com/pytest-dev/pytest/issues/2533>_)

• Improve error message for CollectError with skip/skipif. (2546 <https://github.com/pytest-dev/pytest/issues/2546>_)

• Emit warning about yield tests being deprecated only once per generator.
  (2562 <https://github.com/pytest-dev/pytest/issues/2562>_)

• Ensure final collected line doesn't include artifacts of previous write.
  (2571 <https://github.com/pytest-dev/pytest/issues/2571>_)

• Fixed all flake8 errors and warnings. (2581 <https://github.com/pytest- dev/pytest/issues/2581>_)

• Added fix-lint tox environment to run automatic pep8 fixes on the code.
  (2582 <https://github.com/pytest-dev/pytest/issues/2582>_)

• Turn warnings into errors in pytest's own test suite in order to catch
  regressions due to deprecations more promptly. (2588 <https://github.com/pytest-dev/pytest/issues/2588>_)

• Show multiple issue links in CHANGELOG entries. (2620 <https://github.com/pytest-dev/pytest/issues/2620>_)
