M220P - pytest -m connection failure

I have completed the environment configuration for M220P. ‘python run.py’ executes without error and the webpage comes up on Chrome with no errors. However, the pytest -m connection test is failing with an error for which I have not been able to find a valid resolution. The error is:

file /shared/mflix-python/tests/test_db_connection.py, line 21
@pytest.mark.connection
@pytest.mark.usefixtures(‘config’)
def test_atlas_setup(client, config):
E fixture ‘config’ not found
