How does it enforce the 80% coverage rule?

The skill provides specific workflow steps and configuration patterns for coverage reporting, ensuring that logic, branches, and edge cases are fully accounted for before code is finalized.

Does it handle external service dependencies?

Yes, the skill includes built-in mocking strategies for common services like Supabase, Redis, and OpenAI to ensure your tests remain fast, isolated, and deterministic.

Does this skill support specific testing frameworks?

Yes, it includes optimized patterns and boilerplate for Jest, Vitest, and Playwright, making it ideal for modern JavaScript and TypeScript environments.

Can I use this for existing projects?

Absolutely. It is highly effective for refactoring existing code or adding new features to legacy systems while establishing a new safety net of tests.

Security & Testing

Enforces rigorous test-driven development practices and high code coverage standards to ensure reliable software delivery.

The TDD Workflow skill transforms Claude into a quality-focused engineering partner that mandates a test-first approach to software development. By prioritizing user journeys and failing tests before implementation, it ensures that every new feature, bug fix, or refactoring effort maintains a minimum of 80% coverage across unit, integration, and end-to-end testing layers. It provides standardized patterns for modern stacks including React, Next.js, and Playwright, while offering robust mocking strategies for external services like Supabase and OpenAI, resulting in more maintainable and resilient codebases.
