Which programming languages does this skill support?

The skill includes specific framework recommendations and implementation templates for JavaScript/TypeScript (Vitest, Jest, Playwright), Python (Pytest), and Go.

Does it support mocking external APIs?

Absolutely. It provides specific strategies and code examples for mocking external services using tools like MSW (Mock Service Worker), factory functions, and fixtures.

Can it help with end-to-end (E2E) testing?

Yes, it includes specialized templates and tool recommendations like Playwright, Cypress, and Selenium for testing critical user journeys.

How does it help with code coverage?

It provides a defined coverage strategy with specific thresholds (e.g., 80% global, 95% core) and checklists to ensure business logic and edge cases are fully covered.

Security & Testing

Architects and implements comprehensive testing suites across multiple languages using industry-standard frameworks and the testing pyramid methodology.

About

This skill empowers Claude to design, implement, and optimize robust testing infrastructures for any codebase. It provides a structured workflow covering the entire testing lifecycle—from identifying critical test cases and selecting appropriate frameworks like Vitest, Pytest, or Playwright, to implementing unit, integration, and E2E tests. By applying a rigorous testing pyramid approach and providing standardized templates for mocks and fixtures, it ensures high code quality, reliable coverage targets, and maintainable test suites that prevent regressions.

Key Features

Multi-language support for JavaScript, TypeScript, Python, and Go testing ecosystems
Pre-defined templates for Unit, Integration, and E2E testing patterns
Automated test implementation checklists and validation loops to ensure reliability
1,171 GitHub stars
Standardized testing pyramid implementation for balanced unit, integration, and E2E coverage
Comprehensive mocking strategies and test data management using factories and fixtures

Use Cases

Setting up a new testing infrastructure and framework selection for greenfield projects
Improving code coverage and identifying edge cases in existing business logic
Debugging flaky tests and refactoring legacy test suites for better performance
