The pytest-attrib plugin extends py.test with the ability to select tests
based on a criteria rather than just the filename or pytest.marks. For
example, you might want to run only tests that need internet connectivity,
or tests that are slow.
The pytest.mark plugin already provides a featrure to mark tests and run
only the marked tests. This plugin also allows to run expressions on the
attributes of the class, and does not require the pytest.mark decorator.
It offers features similar to the nose plugin nose-attrib.
