Changelog

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 https://*.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>_)
