advanced skipping of tests
skip or expect-to-fail a test
======================================
py.test has `advanced support for skipping tests`_ or expecting
failures on tests on certain platforms. Apart from the
minimal py.test style also unittest- and nose-style tests
can make use of this feature.
py.test has a dedicated `skipping plugin`_ that allows to define

* define "skip" outcomes indicating a platform or a
dependency mismatch.
* "xfail" outcomes indicating an "expected failure" either with
with or without running a test.
* skip and xfail outcomes can be applied at module, class or method
level or even only for certain argument sets of a parametrized function.
