Tdd Red Green Refactor

What it does

This skill guides an AI agent through Test-Driven Development (TDD) using the Red-Green-Refactor cycle. It helps break down development into small, testable steps, ensuring code quality and maintainability. The process involves writing a failing test ("red"), then writing just enough code to pass that test ("green"), and finally improving the code's structure without changing its behavior ("refactor").

When to use it

• New feature development: Use when building new functionality, ensuring each step is tested and well-defined.
• Refactoring existing code: Apply to improve the design and readability of existing codebases while preserving functionality.
• Debugging complex issues: Isolate problems by writing tests that fail before fixing them, leading to more targeted solutions.
• Collaborative development: Facilitate a shared understanding of requirements and implementation through testable specifications.

Key capabilities

• Guides the agent through Red-Green-Refactor cycles.
• Focuses on iterative code development.
• Emphasizes writing tests before implementing functionality.
• Promotes clean, maintainable code.

Example prompts

• "Let's implement a function to calculate the area of a rectangle using TDD."
• "Refactor this existing function following the Red-Green-Refactor process."
• "Write a failing test for the login functionality and then guide me through writing the code to pass it."

Tips & gotchas

• Requires a basic understanding of unit testing concepts.
• The agent's effectiveness depends on clear, concise prompts outlining the desired functionality or refactoring goals.
