Test-Driven Development in Spring Boot is implemented by writing tests before functionality using JUnit 5, Mockito, and MockMvc. This ensures robust code quality, clean architecture, and continuous refactoring through automated unit and integration testing.

Test Containers are used alongside JUnit 5 and MockMvc for Spring Boot integration testing to manage external dependencies. This integration provides isolated, reliable test environments and validates application behavior comprehensively before deployment.

Yes, Mockito and MockMvc can be used together for Spring Boot unit testing to mock dependencies and test web layers. This combination allows precise validation of controller endpoints and service logic without starting a full server context.

The best way to set up a Spring Boot project with TDD support is running the initialization script to configure JUnit 5, Mockito, and JaCoCo. This establishes an automated testing baseline promoting clean code and continuous refactoring from the start.

JUnit 5 is used for TDD in Spring Boot applications because it provides the foundational framework for writing and executing tests before implementation. It integrates seamlessly with Mockito and MockMvc to enforce rigorous code quality and reduce bugs.

JaCoCo works with Spring Boot Test-Driven Development to measure code coverage by analyzing test execution against implemented code. It provides reports identifying untested paths, ensuring extensive unit and integration testing validates functionality.
