What is the main benefit of using the TDD skill?

It ensures code reliability by defining requirements through tests before implementation, resulting in higher quality, fewer regressions, and better software design.

Does this skill work with all programming languages?

Yes, TDD is a language-agnostic methodology. This skill provides the logical framework that can be applied to any programming language supported by Claude.

Why write tests before code?

Writing tests first provides immediate design feedback, creates executable documentation, and ensures that every line of code is necessary and verifiable.

How does the Red-Green-Refactor cycle work?

You start by writing a failing test (Red), then write the minimum code necessary to pass (Green), and finally improve the code's design while keeping tests passing (Refactor).

Can I use this for legacy code?

Yes, TDD is highly effective for refactoring legacy code by creating a safety net of tests that reproduce existing behavior before making structural changes.

Implements the Red-Green-Refactor cycle to ensure code reliability and high test coverage from the start.

This skill guides developers through the disciplined process of Test-Driven Development (TDD), emphasizing the creation of failing tests before writing production code. By strictly following the Red-Green-Refactor cycle, it helps ensure that software is built on a foundation of executable specifications, reducing bugs and promoting clean, modular architecture. It is particularly valuable when building complex business logic, refactoring legacy systems, or designing robust APIs where maintainability and regression protection are paramount.
