SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Helps teams ensure code correctness from the start by enforcing a test-first workflow.

Core Features & Use Cases

  • Enforces the RED-GREEN-REFACTOR cycle to guide development
  • Supports feature work, bug fixes, and refactors with explicit tests
  • Encourages creating minimal, verifiable production code that passes tests

Quick Start

Begin by writing a failing test, run the tests to observe failure, implement the minimal code to pass, and then refactor for clarity and quality.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enforce a strict test-first development workflow in my software project?▼

You can enforce a test-first development workflow by applying the RED-GREEN-REFACTOR cycle to guide feature implementation. This ensures code correctness from the start by requiring a failing test before writing minimal production code and refactoring.

What is the RED-GREEN-REFACTOR cycle in test-driven development?▼

The RED-GREEN-REFACTOR cycle is a test-driven development process where you write a failing test, implement minimal code to pass the test, and then refactor for clarity. It guides development to ensure code correctness from the start.

How do I apply test-driven development to bug fixes and refactoring?▼

To apply test-driven development to bug fixes and refactoring, you write explicit tests that capture the desired behavior or bug condition. You then implement minimal code changes to pass these tests before refactoring for quality.

What do I need to set up before starting test-driven development?▼

Before starting test-driven development, you need a test runner, the ability to run failing tests to confirm the initial state, and the capability to add minimal implementations and perform safe refactoring across your software project.

Can I use test-driven development for large feature implementations across different software projects?▼

Test-driven development supports feature work, bug fixes, and refactors across software projects wanting to enforce strict test-first workflows. It encourages creating minimal, verifiable production code that passes tests regardless of project scale.
