Test-Driven Development (TDD) Skill

This skill guides the implementation of features using the TDD lifecycle.

When to use this skill

• When developing new features following strict TDD constraints.
• When refactoring legacy code safely by writing tests first.

Guidelines

• Red: Write a failing test for the next piece of functionality. Ensure it fails for the correct reason.
• Green: Write the absolute minimum amount of code necessary to make the test pass.
• Refactor: Improve the code quality, remove duplication, and optimize while ensuring tests remain green.
• Wait on edge cases: Don't write generalized code until the tests explicitly demand it through diverse test cases.
