SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill streamlines the process of writing comprehensive unit and integration tests for Spring Boot applications, ensuring high code coverage and robust development practices.

Core Features & Use Cases

Test-Driven Development (TDD): Guides you through writing tests before implementation.
Comprehensive Testing: Supports unit tests (JUnit 5, Mockito), web layer tests (MockMvc), integration tests (SpringBootTest), and persistence tests (DataJpaTest).
Use Case: When developing a new REST API endpoint in a Spring Boot microservice, use this Skill to generate the necessary tests for the controller, service, and repository layers, ensuring all aspects are covered.

Quick Start

Use the springboot-tdd skill to write a unit test for the MarketService class.

FAQPage Schema

How do I write Spring Boot integration tests for a REST API endpoint?▼

Spring Boot integration tests for REST APIs use MockMvc for the web layer and SpringBootTest to validate controller, service, and repository interactions. This approach ensures comprehensive coverage across all architectural layers using JUnit 5 and AssertJ assertions.

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

Achieving over 80% code coverage in Spring Boot requires combining unit tests, web layer tests, and integration tests. Utilizing Mockito for mocking, Testcontainers for persistence tests, and JaCoCo for reporting ensures comprehensive validation and measurable coverage metrics.

Can I use Testcontainers for persistence testing with DataJpaTest in Spring Boot?▼

Testcontainers supports DataJpaTest persistence testing in Spring Boot by providing isolated database environments. This combination validates repository layer interactions against real databases without compromising test reliability or requiring manual database management.

Does this Spring Boot testing approach work with both Maven and Gradle for CI pipelines?▼

Spring Boot test-driven development integrates natively with both Maven and Gradle for CI pipelines. It executes test commands and generates JaCoCo code coverage reports seamlessly within either build tool's ecosystem.

How do you write a unit test for a Spring Boot service class using Mockito and JUnit 5?▼

Unit testing a Spring Boot service class uses JUnit 5 for test structure and Mockito to mock external dependencies. AssertJ provides readable assertions to verify service logic isolation and behavior.

When do I need MockMvc versus SpringBootTest for Spring Boot web layer testing?▼

MockMvc tests Spring Boot web layer controllers in isolation by mocking HTTP requests, while SpringBootTest validates full application context integration. Choosing between them depends on whether you need focused controller validation or end-to-end request flow verification.
