Nice breakdown. The part that usually decides whether faster tests stay fast is the reset strategy: if state cleanup is deterministic and the failure surface is obvious, teams stop re-running flaky suites and start trusting the feedback loop.
One of the best ways for cleanups is if the testing library wraps each test in a transaction, so no test actually pollutes the database, every test process runs the migration only once and all the assertions are kept in a transaction, frameworks like Laravel and Django do provide this.
Good practical tips. Integration tests usually get slow because teams treat the database like a black box. Cleaning state properly, reusing containers, and avoiding unnecessary setup can save a lot without weakening test confidence.
Exactly. Slow tests often come from heavy setup, not the actual test logic. Keeping fixtures lean and reusing clean environments can make a big difference without reducing confidence.
