How do I start a new TDD session with Claude?

You can initiate the process by typing '/tdd' followed by the name of the function or feature you want to build, such as '/tdd calculateTotal' or '/tdd user-login'.

What are the FIRST principles in testing?

FIRST stands for Fast, Independent, Repeatable, Self-validating, and Timely. These principles ensure that your test suite remains a helpful tool rather than a maintenance burden.

Which testing frameworks does TDD Assistant support?

The skill is designed to be flexible but comes with built-in support for bash commands related to npm scripts and Vitest, making it compatible with most modern JavaScript and TypeScript environments.

What is the Red-Green-Refactor cycle?

It is the core TDD process: first, write a failing test (Red); second, write the minimal code necessary to make the test pass (Green); and third, optimize the code structure without changing its behavior (Refactor).
