If called with callable_obj omitted or None, will return a context object used like this:: with self.assertWarns(SomeWarning): do_something() An optional keyword argument 'msg' can be provided when assertWarns is used as a context object. The context manager keeps a reference to the first matching warning as the 'warning' attribute; similarly, the 'filename' and 'lineno' attributes give you information about the line of Python code from which the warning was triggered.
