What is the minimum code coverage requirement?

The skill is designed to enforce a minimum of 80% coverage across the combined total of unit, integration, and E2E tests.

Can I use this for API development?

Absolutely. It provides dedicated patterns for API integration testing, including request validation and database interaction mocking.

Does this skill support Playwright for E2E testing?

Yes, it includes specific patterns, step-by-step workflows, and best practices for browser automation using Playwright.

How does the workflow handle external dependencies?

The skill includes specialized mocking patterns for common services like Supabase, Redis, and OpenAI to ensure tests remain fast and isolated.

Security & Testing

Implements a rigorous test-driven development cycle to ensure 80% code coverage across unit, integration, and E2E tests.

This skill transforms the development process by mandating a 'test-first' approach for new features, bug fixes, and refactoring. It guides Claude to define user journeys and failing test cases before writing implementation code, supporting popular frameworks like Jest, Vitest, and Playwright. By enforcing an 80% coverage threshold and providing standardized patterns for API and UI testing, it ensures codebases remain robust, maintainable, and resilient against regressions through a structured Red-Green-Refactor workflow.
