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.
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.

The class defining the warning that func is expected to throw.
func : callable
The callable to test.
*args : Arguments
Arguments passed to func.
**kwargs : Kwargs
