Generate JUnit 5 unit tests for Java service classes by mocking collaborators with Mockito to validate behavior. This approach tests pure domain logic, including edge cases and error paths, while enforcing meaningful assertions to prevent regressions.
Use Testcontainers for Java integration testing when data stores or external services like databases, Redis, or Mongo are involved. It spins up Spring contexts to validate real interactions, enforcing rules like no mocking of EntityManager or Jpa in integration tests.
No, you cannot mock EntityManager or Jpa in JUnit 5 integration tests. You must use Testcontainers with Spring contexts to validate real database interactions and enforce meaningful assertions without bypassing the actual data store layer.
The best way to avoid Thread.sleep in JUnit tests is to enforce strict organizational rules during test generation. Create JUnit 5 tests that mock collaborators with Mockito for behavior validation, ensuring meaningful assertions without relying on arbitrary delays.
Yes, JUnit 5 works with Testcontainers for testing Redis interactions. When external services or data stores are involved, apply Testcontainers within Spring contexts to validate real interactions rather than mocking the data layer.
