Setting Up Data Driven Tests with Java Tools
summary
Shows how to provision a real DB per test with Testcontainers, seed and assert state with DBUnit or Database Rider, and run JUnit 5 tests that insert customers and compare expected XML/YAML datasets. Demo uses an Oracle image (official 9 GB / ~3 min start vs lightweight 900 MB / ~10 s), seeds two customers then inserts a third, tests pass and then fail when expected counts change, and containers reinitialize per test for pristine state.
