TDD: seriously, try it!
summary
Shows a concrete TDD workflow by writing Java unit and integration tests, implementing a FilmRecommendationService and FilmRepository, and getting tests green with red‑green‑refactor. Uses JUnit 5 plus AssertJ-style assertions, mocks the repository for the unit test and runs an integration test with Testcontainers+Postgres to verify SQL ordering by average rating. Demonstrates the code that gets written (service + SQL repository), the tests that pass, and notes the steep learning curve and time investment.
