[dependabot-preview]

Updates the requirements on pytest to permit the latest version.

Changelog

Sourced from pytest's changelog.

pytest 4.2.0 (2019-01-30)

Features

• #3094 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/3094>_: Class xunit-style <https://docs.pytest.org/en/latest/xunit_setup.html>__ functions and methods
  now obey the scope of autouse fixtures.

  This fixes a number of surprising issues like setup_method being called before session-scoped
  autouse fixtures (see #517 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/517>__ for an example).

• #4627 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4627>_: Display a message at the end of the test session when running under Python 2.7 and 3.4 that pytest 5.0 will no longer
  support those Python versions.

• #4660 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4660>_: The number of selected tests now are also displayed when the -k or -m flags are used.

• #4688 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4688>_: pytest_report_teststatus hook now can also receive a config parameter.

• #4691 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4691>_: pytest_terminal_summary hook now can also receive a config parameter.

Bug Fixes

• #3547 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/3547>_: --junitxml can emit XML compatible with Jenkins xUnit.
  junit_family INI option accepts legacy|xunit1, which produces old style output, and xunit2 that conforms more strictly to https://github.com/jenkinsci/xunit-plugin/blob/xunit-2.3.2/src/main/resources/org/jenkinsci/plugins/xunit/types/model/xsd/junit-10.xsd

• #4280 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4280>_: Improve quitting from pdb, especially with --trace.

  Using q[quit] after pdb.set_trace() will quit pytest also.

• #4402 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4402>_: Warning summary now groups warnings by message instead of by test id.

  This makes the output more compact and better conveys the general idea of how much code is
  actually generating warnings, instead of how many tests call that code.

• #4536 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4536>_: monkeypatch.delattr handles class descriptors like staticmethod/classmethod.

• #4649 <https://github-redirect.dependabot.com/pytest-dev/pytest/issues/4649>_: Restore marks being considered keywords for keyword expressions.
