Does it handle external API mocking?

Yes, it includes built-in patterns for mocking common services like Supabase, Redis, and OpenAI to ensure test isolation and speed.

How does this skill enforce TDD?

It guides Claude to write user journeys and failing test cases before generating any implementation code, strictly following the Red-Green-Refactor cycle.

Can I use this for existing projects?

Yes, it is excellent for refactoring or adding features to existing codebases by establishing a baseline of tests before making logic changes.

Which testing frameworks are supported?

The skill is optimized for Jest, Vitest, and Playwright, providing specific patterns and file organization strategies for these tools.

What is the minimum coverage requirement?

This skill specifically targets and verifies an 80% or higher coverage threshold across lines, branches, and functions.

Seguridad y Pruebas

Enforces rigorous test-driven development practices with comprehensive unit, integration, and E2E coverage for reliable software delivery.

The TDD Workflow skill transforms Claude into a disciplined testing partner, ensuring that every feature, bug fix, or refactor begins with a robust test suite. By mandating a 'test-first' approach and maintaining a minimum 80% coverage threshold across multiple layers—including unit tests with Vitest, API integration tests, and Playwright-driven E2E flows—it minimizes technical debt and prevents regressions. This skill is ideal for developers and teams prioritizing high-quality code and production stability through automated verification, semantic testing patterns, and structured mocking of external services.
