问题 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 runner and not awaited? @pytest.fixture async def create_x(api_client): x_id = await add_x(api_client) return api_client, x_id 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 producing ==============================
