pytest-2.3.4: stabilization, more flexible selection via “-k expr”

pytest-2.3.4 is a small stabilization release of the py.test tool which offers uebersimple assertions, scalable fixture mechanisms and deep customization for testing with Python. This release comes with the following fixes and features:

  • make “-k” option accept an expressions the same as with “-m” so that one can write: -k “name1 or name2” etc. This is a slight usage incompatibility if you used special syntax like “TestClass.test_method” which you now need to write as -k “TestClass and test_method” to match a certain method in a certain test class.
  • allow to dynamically define markers via item.keywords[...]=assignment integrating with “-m” option
  • yielded test functions will now have autouse-fixtures active but cannot accept fixtures as funcargs - it’s anyway recommended to rather use the post-2.0 parametrize features instead of yield, see: http://pytest.org/latest/example/parametrize.html
  • fix autouse-issue where autouse-fixtures would not be discovered if defined in a a/conftest.py file and tests in a/tests/test_some.py
  • fix issue226 - LIFO ordering for fixture teardowns
  • fix issue224 - invocations with >256 char arguments now work
  • fix issue91 - add/discuss package/directory level setups in example
  • fixes related to autouse discovery and calling

Thanks in particular to Thomas Waldmann for spotting and reporting issues.
