SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enforces the Test-Driven Development (TDD) methodology, ensuring that tests are written before code, leading to more robust and maintainable software.

Core Features & Use Cases

  • Mandatory TDD Workflow: Guides users through the Red-Green-Refactor cycle.
  • Configuration Management: Persists TDD preferences across projects and user settings.
  • Use Case: When starting a new feature, this skill ensures you first define acceptance criteria, write a failing test, implement the minimum code to pass, and then refactor, preventing regressions and improving code quality.

Quick Start

Use the tdd skill to implement the new user authentication feature.

FAQPage Schema
How do I enforce a Test-Driven Development workflow for new features?

To enforce a Test-Driven Development workflow, you must mandate test creation prior to code implementation. This process guides you through defining acceptance criteria, writing failing tests, and implementing the minimum code required to pass.

What is the red-green-refactor cycle and how do I apply it to bug fixing?

The red-green-refactor cycle is a Test-Driven Development practice where you write a failing test, implement code to make it pass, and then refactor. Applying this to bug fixing prevents regressions by validating the fix through initial test failure.

How do I start writing tests before code implementation without breaking my development workflow?

Start writing tests before code implementation by activating a Test-Driven Development workflow that governs your entire lifecycle. It ensures your development workflow transitions smoothly from initial test planning through final validation.

Can I use Test-Driven Development for refactoring tasks and improving code quality?

Yes, you can use Test-Driven Development for refactoring tasks to significantly improve code quality. By mandating tests prior to code changes, it ensures refactoring remains robust and prevents existing functionality from regressing.

Does Test-Driven Development configuration persist across different projects?

Test-Driven Development preferences can persist across projects through dedicated configuration management. This ensures your default development practice for feature implementation and refactoring remains consistent across various user settings.

When should I not use Test-Driven Development for software engineering?

You should avoid Test-Driven Development when exploring throwaway prototypes where immediate validation is unnecessary. Because it mandates tests prior to code implementation, using it for rapid exploratory coding can interrupt your development workflow.
