According to <https://github.com/Disfactory/Disfactory/commit/c66fee554f4bf033fa776d9701334c860acb2bc1|c66fee5> , it seems the current unittest is launched by `pytest` instead of `manage.py test`. *Steps to Test This Pull Request* 1. Launch the dev environment with docker-compose, e.g. `make run-dev` 2. `docker-compose exec web pytest` *Expected Result* `55 passed, 25 warnings` *Additional Information* `docker-compose exec web python manage.py test` does not do anything. Its output is: ``` localhost,127.0.0.1 System check identified no issues (0 silenced). ---------------------------------------------------------------------- Ran 0 tests in 0.000s OK ```
