While there is a warning about mariadb/mysql stuff that doesn't appear to be the issue. Not sure what I'm doing wrong (if anything). Here's the basic test script: ```py import os import pytest @pytest.fixture def flask_app(mysql): os.environ['MYSQL_HOST'] = mysql.host os.environ['MYSQL_PORT'] = str(mysql.port) os.environ['MYSQL_USER'] = mysql.user os.environ['MYSQL_PASSWORD'] = mysql.password os.environ['MYSQL_DATABASE'] = mysql.db from app import app return app def test_home_route(flask_app): response = flask_app.get('/') assert response.status_code == 200 ``` And here's the error when running `pytest -q`: ```pytest E [100%] ========================================================================================================================== ERRORS ========================================================================================================================== ____________________________________________________________________________________________________________ ERROR at setup of test_home_route _____________________________________________________________________________________________________________ request = <SubRequest 'mysql' for <Function test_home_route>> @pytest.fixture def mysql_fixture( request: FixtureRequest, ) -> Generator[Connection, None, None]: """Client fixture for MySQL server. #.
