SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill introduces Test-Driven Development (TDD) principles, helping developers write tests first and improve code quality.

Core Features & Use Cases

RED-GREEN-REFACTOR Cycle: Follow the TDD cycle to write tests, implement code, and refactor for better quality.
Three Laws of TDD: Understand the fundamental rules of TDD to write effective tests and code.
RED Phase Principles: Learn how to write failing tests and identify key aspects to include in your tests.
GREEN Phase Principles: Implement minimal code to pass the test and avoid unnecessary complexity.
REFACTOR Phase Principles: Refactor code to improve quality without breaking tests.
AAA Pattern: Apply the Arrange-Act-Assert pattern for clear and concise tests.
When to Use TDD: Determine the scenarios where TDD is most effective.

Quick Start

Use the tdd-workflow skill to understand the TDD cycle and implement it in your development process.

FAQPage Schema

What is the RED-GREEN-REFACTOR cycle in test-driven development?▼

The RED-GREEN-REFACTOR cycle in test-driven development involves writing a failing test, implementing minimal code to pass it, and refactoring to improve quality. It aims to enhance code maintainability.

How do I apply the AAA pattern when writing unit tests?▼

You apply the AAA pattern by structuring tests into Arrange, Act, and Assert phases. This test-driven development approach ensures clear, concise tests by explicitly separating setup, execution, and verification steps.

When should I use test-driven development in my software development process?▼

Use test-driven development when aiming to improve code quality and maintainability. It is most effective when you need a structured development process that uses tests to drive design.

What are the three laws of TDD?▼

The three laws of TDD are fundamental rules that enforce writing tests first in the development process. They guide developers to write effective tests and implementation code incrementally to ensure better overall quality.

How do I write minimal code to pass a failing test during the GREEN phase?▼

To write minimal code during the GREEN phase of test-driven development, implement only the logic required to make the failing test pass. This avoids unnecessary complexity and ensures your code remains focused and maintainable.

When should I avoid using test-driven development?▼

You should avoid test-driven development when exploring new prototypes or when the requirements are highly volatile. It is designed to streamline the development process for maintainable code, not for rapid, throwaway exploratory coding.
