What is the AAA pattern included in these templates?

AAA stands for Arrange, Act, and Assert. It is a structural pattern that ensures tests are readable and maintainable by clearly separating setup, execution, and verification steps.

What languages does the Test Pattern Library support?

The library provides detailed, ready-to-use patterns for JavaScript/TypeScript (Jest, Vitest, React Testing Library) and Python (pytest, unittest.mock), with additional guidance for Go, Rust, and Java.

Does it cover API integration testing?

Absolutely. It features patterns for API testing using Supertest and Express, including strategies for authentication, input validation, and database setup/teardown.

Can this skill help with React component testing?

Yes, it includes specialized patterns for React Testing Library, covering component rendering, user event simulation, loading states, and snapshot testing.

セキュリティとテスト

Simplifies the creation of high-quality automated tests by providing battle-tested patterns and templates for unit, integration, and end-to-end testing.

概要

The Test Pattern Library skill equips Claude with a comprehensive collection of testing architectures and boilerplate code to ensure software reliability across various environments. It streamlines the development lifecycle by offering language-specific patterns for JavaScript, TypeScript, Python, and more, emphasizing the Arrange-Act-Assert (AAA) structure. Whether you are setting up new testing infrastructure, mocking complex dependencies, or debugging flaky integration tests, this skill provides the domain-specific guidance needed to build maintainable, robust, and high-coverage test suites.
