skipif
Make function raise SkipTest exception if a given condition is true.
If the condition is a callable, it is used at runtime to dynamically make the decision. This is useful for tests that may require costly imports, to delay the cost until the test suite is actually executed.
Flag to determine whether to skip the decorated test.
Message to give on raising a SkipTest exception. Default is None.
Decorator which, when applied to a function, causes SkipTest to be raised when skip_condition is True, and the function to be called normally otherwise.
Notes
The decorator itself is decorated with the nose.tools.make_decorator function in order to transmit function name, and various other metadata.
