test_client fixture broken with pytest==2.3.3

[argaen]

DISCLAIMER: I don't know if this is a pytest or pytest-aiohttp problem, but I think its interesting to follow this here just in case other users ask about it. Pytest issue in pytest-dev/pytest#2975

Long story short

After upgrading to pytest==2.3.3, all tests that use the test_client fixture are skipped.

Expected behaviour

Tests using test_client fixture should run

Steps to reproduce

Super easy to reproduce:

async def test_whatever(test_client):
    pass

With

pytest==3.3.0
aiohttp==2.3.4
pytest-aiohttp==0.1.3

With pytest<=3.3.0 runs fine

I think the issue is the duplicate for #2565

True, closing in favor of that one then
