Spring Boot TDD guides teams to write failing tests first, then implement minimal code to pass, covering unit, integration, and data-layer testing across controllers, repositories, and services.

Testcontainers with SpringBootTest runs integration tests in real, containerized environments to verify component collaboration, ensuring reliable validation that closely mirrors production behavior.

Yes, you can use MockMvc for WebMvc tests to verify controller endpoints and DataJpaTest to validate data access layer logic and entity mappings independently.

JaCoCo provides code coverage verification and enforces thresholds, ensuring tests exceed an 80% coverage requirement during continuous integration workflows.

Yes, JUnit 5 and Mockito support unit testing by verifying service logic behaviors and boundaries, allowing teams to mock dependencies and isolate business rules effectively.

Test data builders improve test readability and maintainability by providing structured, reusable methods for constructing complex test fixtures across unit and integration tests.
