SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill streamlines the process of developing Spring Boot applications using Test-Driven Development (TDD), ensuring robust code coverage and maintainability.

Core Features & Use Cases

  • TDD Workflow: Guides you through writing tests before implementation for new features, bug fixes, or refactoring.
  • Comprehensive Testing: Integrates JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo for unit, web, integration, and persistence testing.
  • Use Case: When adding a new API endpoint to a Spring Boot service, use this Skill to first define the endpoint's behavior with tests, then implement the minimal code to pass, and finally refactor.

Quick Start

Follow the Spring Boot TDD workflow to develop a new feature, ensuring 80%+ code 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 a new Spring Boot API endpoint?▼

Spring Boot TDD guides you through a red-green-refactor cycle to define API behavior with tests using MockMvc before implementation, ensuring robust coverage for new endpoints.

What testing tools do I need for Spring Boot integration tests?▼

Spring Boot integration tests require JUnit 5, Mockito, MockMvc, Testcontainers, and JaCoCo to execute unit, web, and persistence testing while enforcing over 80% code coverage.

How does JaCoCo enforce code coverage in a Spring Boot TDD workflow?▼

JaCoCo enforces code coverage by generating integrated reports during the TDD lifecycle, ensuring new features, bug fixes, and refactoring maintain a minimum of 80% tested coverage.

Can I use Testcontainers with JUnit 5 for Spring Boot persistence testing?▼

Yes, Spring Boot TDD integrates Testcontainers with JUnit 5 to manage database environments for integration and persistence testing, verifying data layer behavior accurately.

What is the best way to fix a Spring Boot bug using TDD?▼

The best way to fix a Spring Boot bug using TDD is writing a failing test that reproduces the issue, implementing the minimal code to pass, and refactoring safely.

When should I use Mockito versus MockMvc in Spring Boot testing?▼

Use Mockito for unit tests to mock service dependencies, and use MockMvc for web layer tests to validate API endpoint behavior without starting a full server context.
