Secrets of the testing masters
summary
Shows that Django fixtures often turn into 18-line JSON blobs because the default user model has about 12 required fields, and recommends replacing repeated fixtures with Factory Boy factories that declare defaults once, support sequence fields, lazy attributes, subfactories, and build vs create. Demonstrates overriding create to hash passwords, and using mock.patch and mock objects to fake external calls (example: forcing requests.get to return a 401 body "bad login") so tests run fast and reliably.
