Changelog

Sourced from pytest's changelog.

Pytest 3.5.1 (2018-04-23)

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-redirect.dependabot.com/pytest-dev/pytest/issues/2798>_)

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

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

Improved Documentation

• Fix typo in caplog fixture documentation, which incorrectly identified
  certain attributes as methods. (#3406 <https://github-redirect.dependabot.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-redirect.dependabot.com/pytest-dev/pytest/issues/3221>_)

• Remove internal _pytest.terminal.flatten function in favor of
  more_itertools.collapse. (#3330 <https://github-redirect.dependabot.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-redirect.dependabot.com/pytest-dev/pytest/issues/3339>_)

• record_property is no longer experimental, removing the warnings was
  forgotten. (#3360 <https://github-redirect.dependabot.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-redirect.dependabot.com/pytest-dev/pytest/issues/3398>_)
