Keynote - Testing in Django
summary
Chronological tour of Django testing 1.0–1.11 gives concrete claims: TestCase’s transaction rollback speeds tests, parallel test workers each get their own database so forks avoid shared-state failures, and unit test subtests run many iterations (often ~200). Tools demonstrated include property-based tests with Hypothesis and mutation testing with mutpy (example: a module with 100% line coverage can still score 64% mutation, while others hit ~89–100%). Example shows moving VAT decision logic into a plain Python class and tests become simple, fast, reliable.
