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.
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.
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.
The decorator itself is decorated with the
nose.tools.make_decoratorfunction in order to transmit function name, and various other metadata.
