Test-driven development for a Spring Boot REST endpoint starts by writing a failing test with MockMvc, implementing the minimal controller code to pass it, then verifying integration stability and coverage with JaCoCo.

Yes, Spring Boot TDD works with Testcontainers for integration testing by spinning up containerized environments that mirror production, ensuring data access layer tests run reliably against real dependencies before verifying with JaCoCo.

The best way to unit test Spring Boot service logic is using JUnit 5 and Mockito to isolate the service, write a failing test first, implement the smallest code to pass, and repeat to ensure maintainable logic.

Using a failing test first workflow in Spring Boot projects enforces disciplined test-driven development, delivering high confidence in code correctness, safer refactoring, and maintainable services or data access layers.

Yes, you can enforce code coverage checks during Spring Boot integration testing by running Maven or Gradle commands with JaCoCo after writing failing tests and implementing the minimal code to pass them.

You need MockMvc for testing web endpoints in isolation, while SpringBootTest handles broader integration testing for data flows, both supporting the test-driven development workflow of writing failing tests first.
