Integration Testing with Spring
summary
Demonstrates practical recipes: uses Spring TestContext Framework with JUnit 5, shows repeated tests creating duplicate rows unless cleanup runs, and proves @Transactional rollback default is far faster than @DirtiesContext (constant per-test overhead). Reveals a pitfall where propagation REQUIRES_NEW commits and leaves a record, explains custom test execution listeners must use mergeMode=MERGE_WITH_DEFAULTS or lose essential listeners, and shows controller tests with mockMvc + @MockBean and reactive checks with WebTestClient.
