-
- Parameters
- ----------
-
- skip_condition : bool or callable
- Flag to determine whether to skip test. 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.
- msg : string
- Message to give on raising a SkipTest exception.
-
- Returns
- -------
- decorator : function
- Decorator, which, when applied to a function, causes SkipTest
- to be raised when the skip_condition was True, and the function
- to be called normally otherwise.
-
- Notes
- -----
- You will see from the code that we had to further decorate the
- decorator with the nose.tools.make_decorator function in order to
- transmit function name, and various other metadata.
