SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill guides teams and developers to adopt test-driven development (TDD) practices, ensuring tests drive implementation to reduce defects and rework.

Core Features & Use Cases

  • Red-Green-Refactor discipline to ensure minimal code and early failure feedback
  • Encourages writing tests before code for new features, bug fixes, and refactors
  • Use Case: When starting a feature, write a failing test first, then implement just enough code to pass

Quick Start

Define a failing test for the target feature and run the test suite to observe the failure. Implement the minimal code required to make the test pass and run tests again to confirm a green result. Refactor for clarity and maintainability, then repeat for subsequent changes.

FAQPage Schema
What is test-driven development and how does it improve software engineering?▼

Test-driven development is a practice where you write failing tests before implementing features. It reduces defects and rework by ensuring tests govern behavior and design throughout the development cycle.

How do I start writing tests before code using the red-green-refactor cycle?▼

To start red-green-refactor, define a failing test for your target feature and run the suite to observe the failure. Implement minimal code to pass the test, then refactor for clarity and maintainability.

Can I use test-first development for bug fixes and refactoring existing code?▼

Yes, test-first development is designed for use during bug fixes and refactors across software projects. Writing tests before code ensures disciplined verification and iterative improvement for existing features.

What's the best way to ensure minimal implementation when writing tests first?▼

The best way to ensure minimal implementation is following the red-green-refactor discipline. Write just enough code to make the failing test pass, then refactor for clarity and maintainability without adding extra behavior.

When should I not use test-driven development for feature development?▼

Test-driven development may not suit exploratory prototyping where requirements are unclear. It requires defined behavior targets to write failing tests first, so highly volatile or undefined feature scopes can limit its effectiveness.
