The test is same as below and given that __spec__ an __name__ are passed as
None where ImportWarning is raised in Lib/importlib/_bootstrap.py 1074 . can we
just use self.assertWarns(ImportWarning) in the test?
>>> __import__('', {'__package__': None, '__spec__': None, '__name__':
>>> '__main__'}, locals={}, fromlist=('foo',), level=1)
<stdin>:1: ImportWarning: can't resolve package from __spec__ or __package__,
falling back on __name__ and __path__
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: attempted relative import with no known parent package
