This test passes with version 0.10.0:

Pipfile:

[packages] pytest-asyncio = "==0.10.0" pytest = "==5.4.3" 

test_request.py:

import pytest class TestFixture: @pytest.mark.asyncio async def test_fixture(self, request): assert request.instance is not None 

Under 0.11.0 (and higher), it fails:

Pipfile:

[packages] pytest-asyncio = "==0.14.0" pytest = "==5.4.3" 

I don't fully understand everything that's going on with event loops behind the scenes, but I guess I'd expect the behavior to remain the same
