SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enforces a rigorous Test-Driven Development (TDD) process, ensuring that all new code is written with corresponding tests that are developed before the implementation code. This prevents bugs, improves code quality, and makes refactoring safer.

Core Features & Use Cases

  • Enforces TDD Cycle: Guides users through the Red-Green-Refactor cycle.
  • Prevents Regressions: Ensures tests catch bugs before they reach production.
  • Improves Design: Writing tests first often leads to cleaner, more testable code.
  • Use Case: When starting a new feature, use this Skill to write a failing test, then write the minimal code to pass, and finally refactor.

Quick Start

Follow the Red-Green-Refactor cycle for all new code development.

Frequently Asked Questions about test-driven-development

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

FAQPage Schema
How do I start writing tests before implementation code using TDD?▼

TDD improves code quality by enforcing the Red-Green-Refactor cycle. Writing tests before implementation prevents bugs, ensures safer refactoring, and naturally leads to cleaner, more testable code designs.

What is the best way to prevent regressions when adding new features?▼

The best way to prevent regressions is using the TDD methodology to write failing tests before the implementation. This ensures new bugs are caught early and existing functionality remains intact during refactoring.

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

Yes, TDD applies to bug fixes and refactoring. You enforce the Red-Green-Refactor cycle to write a failing test reproducing the bug, implement the fix to pass, then refactor safely without breaking existing logic.

Does writing tests first actually improve software design?▼

Writing tests first improves software design by enforcing strict testing principles. It guides developers toward cleaner, more modular, and testable code structures, ensuring overall code integrity before implementation.

When should I not use the Red-Green-Refactor cycle?▼

Avoid the Red-Green-Refactor cycle when strict adherence to testing principles obstructs rapid prototyping or exploratory coding. TDD requires strict discipline to maintain code integrity, which may hinder immediate architectural experimentation.
