The best way to clean up test data with Spring and Hibernate

Demonstrates how to properly clean up test data in Spring and Hibernate integration tests by avoiding @DataJpaTest's transaction rollback approach. Instead, recommends using Hibernate's SchemaManager.truncateMappedObjects() method to truncate tables before each test, allowing service-layer transactions to commit naturally. This approach better mirrors production behavior, prevents LazyInitializationException issues, and ensures proper transaction boundary testing while maintaining clean test data between runs.
