SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This workflow guides teams to implement test-driven development for Spring Boot services, ensuring reliable, maintainable code through structured tests, clear workflows, and enforced coverage targets.

Core Features & Use Cases

  • Guidance for applying unit tests (JUnit 5) and mocks (Mockito) alongside web layer testing (MockMvc) for Spring Boot services
  • Integration testing strategy using Testcontainers to mirror production environments
  • Coverage enforcement with JaCoCo to ensure high-quality, production-ready code

Quick Start

Run a new Spring Boot feature through the TDD workflow to ensure tests pass and maintain high coverage

Frequently Asked Questions about springboot-tdd

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I practice test-driven development for Spring Boot services?▼

Test-driven development for Spring Boot services is guided by writing JUnit 5 tests and Mockito mocks first. The workflow covers REST controllers, services, and data access layers to ensure high coverage and maintainable code.

How do I set up deterministic integration tests in Spring Boot?▼

Deterministic integration tests in Spring Boot use Testcontainers to mirror production environments. This approach ensures repeatable tests by spinning up actual dependencies in isolated containers rather than relying on shared or mocked instances.

What is the best way to enforce test coverage targets when building Spring Boot features?▼

Enforcing test coverage targets for Spring Boot features is done using JaCoCo. It verifies that code remains production-ready by checking that unit tests and integration tests meet defined coverage thresholds before merging.

Can I use MockMvc for web layer testing while applying TDD to my Spring Boot application?▼

MockMvc is used for web layer testing while applying TDD to your Spring Boot application. It tests REST controllers in isolation, complementing unit tests with Mockito and integration tests with Testcontainers.

Does this TDD workflow apply to bug fixes and refactoring or only new feature work?▼

This TDD workflow applies to bug fixes and refactoring in addition to new feature work. It guides structured testing across all Spring Boot service layers to ensure reliable and maintainable code.

Why should I use Testcontainers instead of mocks for Spring Boot integration tests?▼

Testcontainers provides deterministic environments by mirroring production for Spring Boot integration tests. Unlike mocks, it validates actual data access layers against real dependencies, ensuring repeatable and reliable test outcomes.
