What happens when you run manage.py test ?
summary
Examines Django's test lifecycle step by step: create test databases, migrate, run system checks, load and run tests, report results, destroy databases, showing where unittest and Django hand off work. Builds two concrete customizations: a trivial fast runner that subclasses discover runner and always returns an A plus, and an output changer that subclasses unittest's text result to produce emoji test result output; both run and the emoji output works. Contrasts this with pytest hooks (20+ hooks, ~700 plugins) as a more composable alternative.
