SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide and best practices for implementing Test-Driven Development (TDD) specifically for Spring Boot applications, ensuring robust and well-tested code.

Core Features & Use Cases

  • TDD Methodology: Guides users through the Red-Green-Refactor cycle.
  • Testing Frameworks: Demonstrates usage of JUnit 5, Mockito, MockMvc, Spring Boot Test, and Testcontainers.
  • Coverage: Emphasizes achieving high code coverage with JaCoCo.
  • Use Case: When developing a new REST API endpoint in a Spring Boot service, use this Skill to structure your tests first, implement the minimal code to pass, and then refactor, ensuring high test coverage throughout the process.

Quick Start

Use the springboot-tdd skill to write unit tests for a new Spring Boot controller.

FAQPage Schema
How do I apply Test-Driven Development to a Spring Boot REST API?▼

Test-Driven Development for a Spring Boot REST API involves structuring tests first using the Red-Green-Refactor cycle. You write failing tests with JUnit 5 and MockMvc, implement minimal code to pass, and refactor to ensure reliability and over 80% code coverage.

What frameworks are needed for Spring Boot TDD?▼

Spring Boot TDD utilizes JUnit 5, Mockito, MockMvc, Spring Boot Test, Testcontainers, and JaCoCo. These frameworks facilitate unit, web layer, integration, and persistence testing while enforcing high code coverage metrics.

How do I test the web layer in a Spring Boot application?▼

Testing the web layer in a Spring Boot application is done using MockMvc to simulate HTTP requests. It allows you to verify controller routing, request mapping, and response handling without starting a full server context.

Can I use Testcontainers for Spring Boot integration testing?▼

Yes, Testcontainers is used for Spring Boot integration and persistence testing. It provides lightweight, throwaway instances of databases and dependencies, ensuring tests run against realistic environments without manual setup.

What is the best way to achieve 80% code coverage in Java?▼

Achieving 80% code coverage in Java is best accomplished by integrating JaCoCo with a structured TDD workflow. Writing tests before implementation ensures every code path is verified, producing maintainable and well-tested Spring Boot services.

Why use Mockito for unit testing Spring Boot services?▼

Mockito is used for unit testing Spring Boot services to isolate and mock external dependencies. It allows you to verify interactions and stub methods, ensuring tests focus solely on the logic of the unit under test without relying on external systems.
