What testing frameworks are supported?

The workflow is designed to be framework-agnostic and can be adapted to popular tools like Jest, Vitest, Playwright, Cypress, and Pytest depending on your project's environment.

Can I customize the 80% coverage requirement?

While the core skill targets 80% as a best practice, you can provide specific instructions to Claude to adjust these thresholds based on your team's internal requirements.

What is the Red-Green-Refactor cycle in this skill?

It is a three-step process: first, the skill writes a failing test (Red); second, it implements the minimal code required to pass that test (Green); and third, it cleans up the code while ensuring the test remains passing (Refactor).

Does this skill automatically run my tests?

Yes, the skill is configured to trigger test execution commands and analyze the output to verify coverage and passing status before proceeding with implementation.

Security & Testing

Enforces a rigorous test-driven development cycle using the Red-Green-Refactor methodology to ensure high-quality, verified code output.

The TDD Workflow skill empowers Claude to act as a disciplined software engineer by prioritizing test-driven development principles. It guides the AI through the essential steps of writing failing tests before implementation, creating minimal code to pass, and performing safe refactoring. By mandating a comprehensive test pyramid—including unit, integration, and E2E tests—and enforcing an 80% coverage threshold, this skill ensures that every feature developed is robust, maintainable, and free of regressions. It is an ideal companion for developers who want to maintain high standards of code quality and reliability in AI-assisted projects.
