Async fixtures with pytest

Question

How do I define async fixtures and use them in async tests?

The following code, all in the same file, fails miserably. Is the fixture called plainly by the test runn

Answer 1

You only need to mark your tests as async

@pytest.mark.asyncio
async def test_app(create_x, auth):
    api_client, x_id = create_x
    resp = await api_client.get(f'my_res/{x_id}', headers=auth)
    assert resp.status == web.HTTPOk.status_code

This tells pytest to run the test inside an event loop rather than calling it directly.

The fixtures can be marked as normal

@pytest.fixture
async def create_x(api_client):
    x_id = await add_x(api_client)
    return api_client, x_id
