SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill streamlines the process of writing robust tests for Spring Boot applications, ensuring code quality and maintainability through Test-Driven Development (TDD).

Core Features & Use Cases

  • Comprehensive Testing Strategies: Covers unit, web layer, integration, and persistence testing.
  • Tool Integration: Leverages JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo for a complete TDD workflow.
  • Use Case: When developing a new REST API endpoint in a Spring Boot microservice, use this Skill to guide the creation of failing tests first, followed by minimal implementation, and finally refactoring to achieve high code coverage.

Quick Start

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

FAQPage Schema
How do I write Spring Boot tests using Test-Driven Development?▼

Spring Boot TDD involves writing failing tests first using JUnit 5, Mockito, MockMvc, and Testcontainers, then implementing minimal code and refactoring to achieve over 80% code coverage.

Can I use Testcontainers for Spring Boot integration and persistence testing?▼

Yes, Testcontainers is fully supported for Spring Boot integration and persistence testing, allowing you to spin up Docker containers to test database interactions and achieve reliable test results.

What's the best way to achieve over 80% code coverage in a Spring Boot application?▼

Achieving over 80% code coverage in Spring Boot requires comprehensive unit, web layer, and integration tests using JUnit 5, Mockito, and JaCoCo to measure and enforce coverage thresholds.

Does this TDD workflow support bug fixing and refactoring existing Spring Boot microservices?▼

Yes, the TDD workflow supports bug fixing and refactoring within Spring Boot projects by guiding developers to create robust failing tests first, ensuring code quality and maintainability.

How do I test a Spring Boot REST API endpoint with MockMvc?▼

Testing a Spring Boot REST API endpoint with MockMvc involves creating web layer tests that simulate HTTP requests and verify responses, ensuring the endpoint behaves correctly before full integration testing.
