mvpa2.testing.tools.skipif

mvpa2.testing.tools.skipif(skip_condition, msg=None)

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.

Parameters:

skip_condition : bool or callable

Flag to determine whether to skip the decorated test.

msg : str, optional

Message to give on raising a SkipTest exception. Default is None.

Returns:

decorator : function

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.
