SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This guide helps developers adopt a comprehensive TDD workflow for Spring Boot services, reducing bugs and increasing maintainable code by emphasizing tests from unit to integration levels.

Core Features & Use Cases

  • Guidance for unit tests (JUnit 5 + Mockito)
  • Web layer and integration testing patterns (MockMvc, DataJpaTest)
  • End-to-end testing workflow including Testcontainers and JaCoCo coverage
  • CI-ready commands and best practices to enforce fast, deterministic tests

Quick Start

Follow the Spring Boot TDD workflow to go from failing tests to green, with clear steps and example test cases.

FAQPage Schema
What's the best way to test the web layer in a Spring Boot application?

Spring Boot integration testing uses Testcontainers to spin up real dependencies and DataJpaTest for database slices validation. This ensures end-to-end test determinism by validating service behavior against actual runtime environments.

Can I enforce JaCoCo test coverage in my Spring Boot CI pipeline?

Yes, the Spring Boot TDD workflow provides CI-ready commands to enforce JaCoCo test coverage thresholds. This ensures your pipeline fails when code coverage drops below acceptable levels during automated builds.

Does this TDD workflow apply to bug fixes and refactoring existing Spring Boot code?

Yes, the TDD workflow applies to bug fixes and refactoring existing Spring Boot services alongside new feature development. It uses JUnit 5 and Mockito patterns to ensure changes maintain high test coverage and code stability.

How do I write deterministic unit tests for Spring Boot using JUnit 5 and Mockito?

Spring Boot unit testing with JUnit 5 and Mockito isolates service logic by mocking external dependencies. This ensures fast, deterministic test execution by validating functional behavior without loading the full application context.
