Issue 36222: ValueError: a coroutine was expected with asyncio.run (original) (raw)
Refs: https://github.com/Martiusweb/asynctest/issues/114
I was trying to mock a asyncio.run(asyncio.gather())
call and I discovered that while it was working with loop.run_until_complete
it wasn't with asyncio.run
Is there a reason for this difference of behaviour?
import asyncio
from unittest.mock import Mock
class AsyncMock(Mock):
def __call__(self, *args, **kwargs):
sup = super(AsyncMock, self)
async def coro():
return sup.__call__(*args, **kwargs)
return coro()
def __await__(self):
return self().__await__()
mocked_function = AsyncMock()
asyncio.run(asyncio.gather(mocked_function()))
import asyncio
from unittest.mock import Mock
class AsyncMock(Mock):
def __call__(self, *args, **kwargs):
sup = super(AsyncMock, self)
async def coro():
return sup.__call__(*args, **kwargs)
return coro()
def __await__(self):
return self().__await__()
mocked_function = AsyncMock()
loop = asyncio.get_event_loop()
loop.run_until_complete(asyncio.gather(mocked_function()))
