How does the 80% coverage requirement work?

The skill guides the AI to run coverage reports and identify specific lines or branches that lack tests, ensuring the final implementation meets the 80% threshold.

Does it support End-to-End (E2E) testing?

Absolutely. It includes dedicated workflows for Playwright to ensure critical user journeys and UI interactions are verified in a real browser environment.

Does this skill work with any testing framework?

While the skill provides specific patterns for Jest, Vitest, and Playwright, its core TDD principles and workflow can be adapted to any modern testing stack.

Can it help with mocking external APIs?

Yes, it includes built-in patterns for mocking common services like Supabase, Redis, and OpenAI to ensure your tests remain fast, isolated, and cost-effective.

When is the best time to activate the TDD Workflow?

You should activate it at the start of any task involving code changes, including feature development, bug fixes, or architectural refactors.

Seguridad y Pruebas

Enforces test-driven development principles and mandatory 80% coverage across unit, integration, and E2E testing layers.

The TDD Workflow skill transforms Claude into a disciplined software engineer by mandating a 'tests-first' approach for all new features, bug fixes, and refactorings. It guides the development process through a rigorous cycle of writing user journeys, defining failing tests, implementing minimal code, and refactoring, while ensuring a minimum 80% code coverage threshold is met. This skill is indispensable for developers prioritizing code reliability, long-term maintainability, and regression prevention in modern JavaScript and TypeScript environments.
