SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill provides a structured approach to implementing features or bugfixes by enforcing a Red-Green-Refactor cycle, ensuring tests drive code quality from the start.

Core Features & Use Cases

  • Structured workflow: Guides teams through writing failing tests first, then minimal code to pass, followed by refactoring for clarity.
  • Quality assurance: Embeds tests into development to catch regressions early and improve maintainability.
  • Applicable scenarios: Ideal for feature development, bug fixes, and refactors across codebases that rely on test suites.

Quick Start

Begin by writing a failing test for the new or modified feature, then implement just enough code to pass, and refactor for clarity and quality.

FAQPage Schema
How do I implement test-driven development in JavaScript and TypeScript projects?▼

This skill automates test-driven development by enforcing the Red-Green-Refactor workflow in JavaScript and TypeScript projects. It guides you to write a failing test first, implement minimal code to pass, and then refactor for clarity.

What is the Red-Green-Refactor workflow for unit tests?▼

The Red-Green-Refactor workflow is a disciplined test-driven development cycle where you write a failing test first, implement minimal code to make it pass, and then refactor for clarity and maintainability.

Does this test-driven development approach work with npm and yarn test commands?▼

Yes, this test-driven development approach integrates with standard test runners using npm and yarn test commands. It is designed for JavaScript and TypeScript projects that rely on these test suites.

When should I use TDD cycles for bug fixes and refactoring?▼

You should use TDD cycles for bug fixes and refactoring when you want to catch regressions early and improve maintainability. This structured workflow ensures your test suite drives code quality across feature development and modifications.

How do I start writing a failing test for a new feature?▼

To start writing a failing test for a new feature, you define the expected behavior in your test suite first. Then you implement just enough code to make the test pass, and finally refactor for quality.
