SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enforces a rigorous development process that leads to more robust, maintainable, and bug-free code by ensuring tests are written before implementation.

Core Features & Use Cases

Enforces Test-First Development: Guides users to write failing tests before writing any production code.
Red-Green-Refactor Cycle: Implements the core TDD loop for iterative development.
Use Case: When starting a new feature, use this Skill to ensure you write a test that defines the expected behavior, then write the minimal code to pass that test, and finally refactor.

Quick Start

Follow the test-driven development process for any new feature or bug fix.

FAQPage Schema

How do I start using test-driven development for new features?▼

Test-driven development starts by writing a failing test that defines expected behavior, then writing minimal code to pass it, and finally refactoring. This enforces the Red-Green-Refactor cycle for iterative development.

What is the Red-Green-Refactor cycle in TDD?▼

The Red-Green-Refactor cycle is the core TDD loop. You write a failing test (Red), implement minimal code to make it pass (Green), and refactor the code while keeping tests green to improve code quality.

Can I use TDD for bug fixes and refactoring existing code?▼

Yes, test-driven development applies to bug fixes and refactoring. You write a test defining the expected behavior or verifying the bug, then implement minimal changes to pass the test before refactoring.

Why write failing tests before implementation code?▼

Writing failing tests before implementation ensures verifiable code and reduces bugs. This strict testing principle enforces test-first development, leading to more robust, maintainable code.

Does test-driven development work within an agile development process?▼

Yes, test-driven development integrates with agile processes. It enforces a rigorous iterative development loop, ensuring code quality and reducing bugs across iterative development cycles.
