  expected warnings and the list of caught warnings is added to the
  error message. Thanks lesteve for the PR.

  zope.interface (1989). Thanks nicoddemus for the PR.

  Thanks RonnyPfannschmidt for the report and nicoddemus_ for the PR.

  subdirectories with ini configuration files now uses the correct ini file
  (2148). Thanks pelme.

• Fail testdir.runpytest().assert_outcomes() explicitly if the pytest
  terminal output it relies on is missing. Thanks to eli-b_ for the PR.
