SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires typescript, jest, vitest, and includes scripts (resource) components.

What problem does it solve?

This Skill ensures a disciplined Red-Green-Refactor (TDD) workflow in TypeScript/Node.js, promoting high-quality, verifiable code implementations during feature development, bug fixing, or logic migration.

Core Features & Use Cases

  • TDD Workflow: Enforces the Red-Green-Refactor TDD cycle for TypeScript/Node.js projects.
  • Incremental Loop: Guides through the process of writing a test, making it pass, and then refactoring.
  • Type Safety: Utilizes TypeScript to enforce type safety and prevent low-quality code.

Quick Start

Start the TDD cycle by writing a test for the new feature, make it fail, then write the minimal code to pass the test, and finally refactor the code.

FAQPage Schema
How do I enforce a strict test-driven development workflow in TypeScript?▼

To enforce test-driven development in TypeScript, you apply a structured Red-Green-Refactor cycle. This workflow requires writing a failing test first, implementing minimal code to pass it, and then refactoring while maintaining type safety.

What is the Red-Green-Refactor cycle for Node.js feature development?▼

The Red-Green-Refactor cycle is a test-driven development process for Node.js. You write a failing test, implement the minimal code to make it pass, and then refactor the implementation to ensure high-quality, verifiable code.

Can I use Vitest or Jest for TDD in a Node.js project?▼

Yes, you can use Vitest or Jest for TDD in a Node.js project. Both testing frameworks are supported to run the incremental test cycles and verify your TypeScript code implementations during development.

How do I start the TDD cycle when fixing bugs or migrating logic?▼

To start the TDD cycle for bug fixing or logic migration, you write a test that captures the expected behavior or validates the bug. Let the test fail, write minimal code to pass it, and refactor incrementally.

Does test-driven development with TypeScript prevent low-quality code?▼

Yes, test-driven development with TypeScript prevents low-quality code. Combining TDD incremental loops with TypeScript type safety enforces verifiable implementations and strict structural validation throughout feature development.
