Is this skill language-specific?

No, these patterns are universal and designed to be language-agnostic, though framework-specific details can be integrated via references.

What is the Arrange-Act-Assert (AAA) pattern included in this skill?

AAA is a standard way of structuring test methods into three distinct functional sections: setting up data (Arrange), executing the code (Act), and verifying results (Assert).

Does this skill help with database testing?

Yes, it includes specific strategies for database isolation, such as transaction rollbacks and table truncation, to ensure tests remain independent and fast.

How does this improve Claude's code generation?

It provides Claude with specific architectural rules and naming conventions to follow when creating tests, ensuring generated code adheres to industry best practices.

Security & Testing

Implements language-agnostic testing strategies and architectural patterns to ensure high-quality, maintainable, and deterministic codebases.

About

The Testing Patterns skill provides Claude with a comprehensive framework for designing and implementing robust software tests across the entire development lifecycle. It codifies universal best practices such as the Test Pyramid, the Arrange-Act-Assert (AAA) pattern, and sophisticated dependency isolation techniques. By integrating these patterns, the skill helps developers move beyond basic coverage to create test suites that are fast, reliable, and properly balanced between unit, integration, and end-to-end testing, regardless of the programming language being used.
