numpy.testing.assert_warns(warning_class, *args, **kwargs)
[source] -
Fail unless the given callable throws the specified warning.
A warning of class warning_class should be thrown by the callable when invoked with arguments args and keyword arguments kwargs. If a different type of warning is thrown, it will not be caught, and the test case will be deemed to have suffered an error.
If called with all arguments other than the warning class omitted, may be used as a context manager:
- with assert_warns(SomeWarning):
- do_something()
The ability to be used as a context manager is new in NumPy v1.11.0.
New in version 1.4.0.
