# pytest-2.6.1: fixes and new xfail feature

pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms. The 2.6.1 release is drop-in compatible to 2.5.2 and actually fixes some regressions introduced with 2.6.0. It also brings a little feature to the xfail marker which now recognizes expected exceptions, see the CHANGELOG below.

See docs at:

> http://pytest.org

As usual, you can upgrade from pypi via:

    pip install -U pytest

# Changes 2.6.1

- No longer show line numbers in the –verbose output, the output is now purely the nodeid. The line number is still shown in failure reports. Thanks Floris Bruynooghe.
- fix issue437 where assertion rewriting could cause pytest-xdist slaves to collect different tests. Thanks Bruno Oliveira.
- fix issue555: add “errors” attribute to capture-streams to satisfy some distutils and possibly other code accessing sys.stdout.errors.
- fix issue547 capsys/capfd also work when output capturing (“-s”) is disabled.
- address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via an optional “raises=EXC” argument where EXC can be a single exception or a tuple of exception classes. Thanks David Mohr for the complete PR.
- fix integration of pytest with unittest.mock.patch decorator when it uses the “new” argument. Thanks Nicolas Delaby for test and PR.
- fix issue with detecting conftest files if the arguments contain ”::” node id specifications (copy pasted from “-v” output)
- fix issue544 by only removing “@NUM” at the end of ”::” separated parts and if the part has an ”.py” extension
- don’t use py.std import helper, rather import things directly. Thanks Bruno Oliveira.
