How does it help with refactoring?

During the Refactor phase, the skill ensures that all tests remain green after every change, allowing you to clean up code and remove duplication without accidentally changing the application's behavior.

What is the Green phase in this TDD workflow?

The Green phase focuses on writing the absolute minimum amount of code required to make the failing test pass. It discourages adding 'extra' features or refactoring until the test is passing.

Can I write production code before the test using this skill?

No. The TDD skill enforces a 'Test First' rule. If production code is written before a failing test, the skill mandates deleting the code and restarting the cycle to ensure true TDD compliance.

Why does this skill insist on watching a test fail?

Watching a test fail ensures that the test is actually checking the right thing. If you don't see it fail, you have no proof that the test is capable of catching a bug or validating the specific behavior you're implementing.

Enforces the Red-Green-Refactor cycle to ensure code reliability and high-quality software architecture.

소개

The TDD skill automates and enforces the rigorous Test-Driven Development methodology within Claude Code. By mandating the Red-Green-Refactor cycle, it ensures that every line of production code is preceded by a failing test, eliminating the risk of 'always-pass' tests that fail to validate logic. This skill provides structured checklists for each phase, integrates TDD directly into implementation plans, and includes deviation logging to prevent the introduction of untested code, making it essential for teams prioritizing long-term maintainability.
