SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enforces the principles of Test-Driven Development (TDD) by ensuring that tests are written before or alongside implementation code, preventing untested code from being committed.

Core Features & Use Cases

TDD Guidance: Provides principles, patterns, and best practices for TDD.
Language-Specific Frameworks: Offers quick references for popular testing frameworks across various programming languages.
Test Design Principles: Details on effective test writing, naming, and structure.
Use Case: When starting a new feature, consult this Skill for guidance on writing the initial failing test and following the Red-Green-Refactor cycle.

Quick Start

Use the tdd-enforce skill to learn about the Red-Green-Refactor cycle.

FAQPage Schema

How do I enforce Test-Driven Development practices in my coding workflow?▼

To enforce Test-Driven Development, you follow the Red-Green-Refactor cycle by writing a failing test before implementation, ensuring no untested code is committed. This methodology improves code quality and maintainability.

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

The Red-Green-Refactor cycle in TDD involves writing a failing test, writing the minimum implementation code to make it pass, and then refactoring the code. This ensures continuous test coverage and clean architecture.

How do I design effective unit tests before writing implementation code?▼

Designing effective unit tests requires following specific test design principles for naming, structure, and patterns. Writing tests first ensures the implementation meets the expected behavior and maintains high code quality.

Can I get TDD guidance for multiple programming languages and testing frameworks?▼

Yes, TDD guidance includes quick references for popular testing frameworks across various programming languages. This allows you to apply test design principles and the Red-Green-Refactor cycle regardless of your tech stack.

When do I need to use TDD practices instead of writing tests after implementation?▼

You need TDD practices when starting a new feature to ensure tests dictate design from the start. Writing tests before or alongside implementation prevents untested code from being committed and ensures maintainability.

What are the limitations of enforcing TDD for refactoring existing code?▼

Enforcing TDD for refactoring requires existing test coverage to ensure safety. While the Skill provides guidance on test design patterns and the Red-Green-Refactor cycle, legacy code without unit tests may need initial test scaffolding before strict TDD adherence.
