 If your stack is already up and you just want to run the tests, you can use:
 
 ```bash
-docker compose exec backend /app/tests-start.sh
+docker compose exec backend bash /app/tests-start.sh
 ```
 
 That `/app/tests-start.sh` script just calls `pytest` after making sure that the rest of the stack is running. If you need to pass extra arguments to `pytest`, you can pass them to that command and they will be forwarded.
