概要
The JUnit Core skill provides Claude Code with a comprehensive framework for writing high-quality Java unit tests using the JUnit 5 (Jupiter) ecosystem. It enforces industry-standard best practices, including the Arrange-Act-Assert (AAA) pattern for readable test logic, a strict 1:1 mapping between production and test classes, and descriptive naming conventions through the @DisplayName annotation. By integrating coverage analysis standards, this skill helps developers maintain a minimum of 80% line and branch coverage, ensuring that critical paths and public APIs remain robust and reliable.
