Can I use this for both frontend and backend testing?

Yes, it includes specialized rules for frontend components via RTL and Playwright, as well as comprehensive backend Python testing patterns with pytest.

Does this skill provide guidance on API mocking?

Absolutely. It contains specific rules for MSW (Mock Service Worker) handlers and Playwright network interception to create deterministic tests without real backend dependencies.

How does this skill help with flaky tests?

It enforces strict test isolation, mock resetting between tests, and provides specific 'quarantine' strategies to identify and fix flaky tests in CI pipelines.

What frameworks does the Testing Strategy skill support?

It supports a wide range of modern tools including Vitest 3.x, Playwright 1.45+, pytest 8.x, MSW 2.x, and React Testing Library 16.x.

What is the primary benefit of the AAA pattern mentioned?

The Arrange-Act-Assert (AAA) pattern ensures tests are readable and maintainable by clearly separating the setup, execution, and verification phases of every test case.

Security & Testing

Standardizes test implementations across Vitest, Playwright, and pytest to ensure high-quality, reliable software delivery.

This skill provides a comprehensive framework of 46 testing rules designed to improve code reliability and maintainability across both JavaScript/TypeScript and Python ecosystems. It guides developers through best practices for unit testing with Vitest and pytest, integration testing with MSW and React Testing Library, and end-to-end automation with Playwright. By enforcing patterns like the Arrange-Act-Assert (AAA) structure, mock boundaries, and meaningful coverage, it helps teams reduce flaky tests, manage complex mock states, and build robust CI/CD pipelines.
