Flask test_client unable to see database fixture

In my test file I have a seeded db test fixture that uses a test db fixture, test_engine, created in conftest.py. I test the module fine but when I use flask test_client to test my routes the test_client is unable to see my test database. I checked here for reference and consulted this answer to no avail.
