What is the main goal of the TDD Workflow skill?

It ensures all code development follows TDD principles, requiring tests to be written before implementation and achieving at least 80% coverage.

How does it handle external services like databases?

The skill includes specific patterns for mocking external dependencies like Supabase, Redis, and OpenAI to ensure isolated and reliable tests.

Which testing frameworks does this skill support?

It provides patterns and workflows for Jest, Vitest, and Playwright, covering unit, integration, and end-to-end testing scenarios.

Can I use this for existing projects?

Yes, it is ideal for refactoring existing code or fixing bugs by first establishing a failing test case to define the expected behavior before making changes.

Does it support coverage reporting?

Yes, it includes steps to run coverage reports and verify that the code meets the global 80% threshold for branches, functions, and lines.

Security & Testing

Enforces test-driven development principles to ensure high-quality code with mandatory 80%+ test coverage across unit, integration, and E2E layers.

The TDD Workflow skill automates and enforces a rigorous Test-Driven Development (TDD) cycle within Claude Code, ensuring that tests are written before implementation begins. It provides standardized patterns for unit testing with Jest/Vitest, API integration testing, and end-to-end browser automation using Playwright. By mandating a minimum of 80% code coverage and offering detailed guidance on mocking external services like Supabase and Redis, it helps developers build resilient, bug-free applications while maintaining a clean, refactored codebase.
