2.7Key Takeaways
- Newman runs Postman collections in CI — quick to set up, limited in flexibility
- pytest + requests provides full programmatic control for production test suites
- Use fixtures for shared setup: auth, API sessions, test data factories
- Factory fixtures with cleanup prevent test data accumulation
- Parametrize for data-driven testing instead of duplicating test functions
- The hybrid approach (Postman for exploration, pytest for CI) works well for many teams
