[New-bugs-announce] [issue38859] AsyncMock says it raises StopIteration but that is Impossible

[Jason Fried]

New submission from Jason Fried <me at jasonfried.info>:

If an AsyncMock uses a side_effect that is an Iterable, if called more than items exist its suppose to raise StopIteration according to the docs but PEP 479 says that is impossible. 

My Suggestion is that we update the docs and the code to Raise a StopAsyncIteration since it will not be converted to a RuntimeError
