Security & Testing

Enforces rigorous test-driven development practices to ensure high code quality and 80%+ test coverage across unit, integration, and E2E tests.

The TDD Workflow skill guides developers through a complete Test-Driven Development lifecycle within Claude Code, from defining user journeys and writing failing tests to implementation and refactoring. It provides standardized patterns for Jest, Vitest, and Playwright while enforcing a mandatory 80% coverage threshold. By integrating advanced mocking strategies for services like Supabase, Redis, and OpenAI, this skill helps maintain a robust safety net for new features, bug fixes, and large-scale code refactoring.

Key Features

01Provides boilerplate patterns for Jest, Vitest, and Playwright testing frameworks.

02Sets a mandatory 80%+ code coverage threshold across unit, integration, and E2E tests.

03Enforces a strict 'Test-First' implementation cycle for all development tasks.

04Includes comprehensive mocking strategies for external APIs, databases, and LLM services.

05Standardizes test file organization and naming conventions for better maintainability.
