SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill ensures code quality by requiring tests to fail before implementing features, reducing regressions and clarifying design intent.

Core Features & Use Cases

  • Red-Green-Refactor: Follow the classic TDD loop to write a failing test, make it pass with minimal code, then clean up.
  • Guided development: Applies to new features, bug fixes, and refactors across projects, preventing premature shipping.
  • Clear workflow: Provides a repeatable process that improves maintainability and confidence in delivered code.

Quick Start

  1. Write a small failing test for a new behavior.
  2. Implement the minimal production code to pass the test.
  3. Run the full test suite and refactor as needed.

FAQPage Schema
What is test-driven development and how does the red-green-refactor cycle work?▼

Test-driven development is a coding workflow where you write a failing unit test, implement the minimal code to pass it, and then refactor. This red-green-refactor cycle ensures code correctness and clarifies design intent before features ship.

How do I write unit tests before implementing new software features?▼

To write unit tests before implementation, start by defining a new behavior with a small failing test. Next, write the minimal production code required to make that test pass, and finally run the full test suite to verify before refactoring.

Can I apply test-driven development to bug fixes and refactoring existing code?▼

Yes, test-driven development applies to bug fixes and refactoring across software projects. You write a failing test that reproduces the bug or validates the refactored behavior, then implement minimal code to make the test pass and prevent regressions.

What is the best way to prevent code regressions and improve maintainability?▼

The best way to prevent regressions is enforcing a test-driven development pipeline. By requiring authentic, minimal tests to fail before implementation, you translate requirements into maintainable software and gain confidence in delivered code.

Does test-driven development require any specific testing frameworks or dependencies?▼

No specific testing frameworks or dependencies are required. The test-driven development workflow focuses on the disciplined process of writing failing unit tests and minimal implementation code, which can be applied across any software project environment.
