Mocking async call in python 3.5

Question

How do I mock async call from one native coroutine to other one using unittest.mock.patch?

I currently have quite an awkward solution:

c

Based on @scolvin answer I created this (imo) cleaner way:

def async_return(result):
    f = asyncio.Future()
    f.set_result(result)
    return f

That's it, just use it around whatever return you want to be async, as in

mock = MagicMock(return_value=async_return("Example return"))
await mock()
