SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill streamlines the process of developing Spring Boot applications by enforcing Test-Driven Development (TDD) practices, ensuring robust code and high test coverage.

Core Features & Use Cases

  • TDD Workflow Guidance: Provides a structured approach to writing tests before implementation.
  • Test Suite Examples: Demonstrates unit, web layer, integration, and persistence tests using JUnit 5, Mockito, MockMvc, and Testcontainers.
  • Coverage Enforcement: Integrates JaCoCo for measuring and enforcing code coverage.
  • Use Case: When building a new REST API endpoint in a Spring Boot microservice, use this Skill to guide the creation of failing tests, implement the minimal code to pass, refactor, and ensure 80%+ code coverage.

Quick Start

Use the springboot-tdd skill to generate unit tests for a new Spring Boot service.

FAQPage Schema
How do I implement Test-Driven Development in a Spring Boot application?

Test-Driven Development in a Spring Boot application involves writing failing tests first, implementing minimal code to pass, and refactoring. This Skill guides that cycle using JUnit 5, Mockito, MockMvc, and Testcontainers for robust unit, web, and integration testing.

How do I write integration tests for a Spring Boot REST API using Testcontainers?

Writing integration tests for a Spring Boot REST API using Testcontainers requires defining expected endpoint behaviors first. This Skill structures tests for the web layer and persistence, ensuring high code coverage and valid API responses before actual implementation.

Can I enforce code coverage thresholds in Spring Boot projects with JaCoCo?

You can enforce code coverage thresholds in Spring Boot projects with JaCoCo by integrating it into your build process. This Skill configures JaCoCo to measure and enforce minimum coverage standards, ensuring 80% or higher test coverage for new features.

What's the best way to unit test a Spring Boot service with Mockito and JUnit 5?

Unit testing a Spring Boot service with Mockito and JUnit 5 is best achieved by mocking dependencies before writing service logic. This Skill provides structured examples to isolate service behavior, validate edge cases, and maintain high code quality through strict TDD practices.

Does Test-Driven Development work for bug fixing and refactoring existing Spring Boot code?

Test-Driven Development works effectively for bug fixing and refactoring existing Spring Boot code by reproducing the bug with a failing test first. This Skill applies the TDD cycle to secure existing logic before applying fixes, preventing future regressions.
