What is the Arrange-Act-Assert (AAA) pattern?

It is a structural standard where tests are divided into three clear phases: Arrange (setup), Act (execution), and Assert (verification) to ensure clarity and consistency.

What is the recommended test distribution in this skill?

The skill follows a pyramid model recommending 60-70% Unit tests, 20-30% Integration tests, and 5-10% End-to-End (E2E) tests for optimal speed and reliability.

Which testing frameworks are supported?

It provides specific patterns and directory structures for Jest (JavaScript/TypeScript), Pytest (Python), and React Testing Library, though the principles apply broadly.

Does it help with test organization?

Yes, it defines specific file naming conventions (like *.test.ts or test_*.py) and directory structures for both co-located and separate test folders.

How does this skill handle code coverage?

It suggests specific targets based on code type: 90% for business logic, 95% for utility functions, and 70% for UI components, prioritizing quality over raw percentage.

セキュリティとテスト

Implements standardized testing architectures using test pyramid principles, coverage targets, and framework-specific patterns for modern development.

The Testing Strategies skill provides Claude with a comprehensive framework for designing and implementing high-quality test suites. It focuses on the 'test pyramid' model to ensure an optimal balance between fast unit tests, reliable integration tests, and critical end-to-end journeys. By enforcing proven patterns like Arrange-Act-Assert (AAA), test isolation, and behavior-driven verification, this skill helps development teams reduce technical debt, eliminate flaky tests, and maintain clear coverage targets across various code types, including specific implementations for Jest, Pytest, and React Testing Library.
