What is the primary focus of this skill?

It focuses on implementing a strict Red-Green-Refactor workflow for Spring Boot development, ensuring code quality through various levels of testing.

Which frameworks does it support?

It supports the modern Spring Boot testing stack including JUnit 5, Mockito for mocking, MockMvc for web layers, and Testcontainers for real database integration.

Is this skill compatible with existing projects?

Absolutely; it can be applied to both greenfield projects and existing Spring Boot applications for feature development or bug fixes.

How does it handle test coverage?

The skill enforces an 80% coverage threshold using JaCoCo, providing configurations for both Maven and Gradle to generate detailed reports.

Can it help with integration testing?

Yes, it provides specific patterns for using Testcontainers to spin up ephemeral Postgres or Redis instances for realistic integration tests.

Security & Testing

Implements robust Test-Driven Development workflows for Spring Boot applications using modern testing frameworks and high-coverage standards.

This skill empowers Claude to act as a senior Java developer specializing in Test-Driven Development (TDD) for Spring Boot services. It provides standardized guidance on the Red-Green-Refactor cycle, ensuring that new features, bug fixes, and refactors are backed by a comprehensive suite of unit, web, and integration tests. By leveraging JUnit 5, Mockito, Testcontainers, and MockMvc, the skill enforces an 80%+ code coverage requirement and promotes clean architectural patterns like Arrange-Act-Assert and Test Data Builders.
