Test-Driven Development in Spring Boot follows the RED-GREEN-REFACTOR cycle using JUnit 5: write failing tests first, implement minimal code to pass, then refactor. This approach ensures robust, well-tested code with high coverage across unit and integration layers.

The best way to test the Spring Boot web layer and persistence is using MockMvc for web layer tests and Spring Data JPA for persistence tests. This Skill provides examples for both, ensuring comprehensive test coverage for REST API endpoints.

To use Testcontainers for integration testing in Spring Boot, you create realistic testing environments for dependencies like Kafka and Redis. This Skill demonstrates advanced testing techniques to ensure your integration tests run against accurate, containerized environments.

Yes, Spring Cloud Contract works with Spring Boot TDD for contract testing. This Skill covers advanced testing techniques including contract testing with Spring Cloud Contract, ensuring your microservices interact reliably through verified contracts.

To assess test quality using mutation testing with PIT in Spring Boot, you evaluate whether your existing tests can detect intentionally introduced code mutations. This Skill covers PIT mutation testing to verify your test suite effectively catches potential defects.

You need Mockito for unit testing in a Spring Boot microservice when isolating specific components and mocking dependencies to verify individual behavior. This Skill demonstrates unit test implementation using Mockito alongside JUnit 5 for focused, reliable component testing.
