What are the FIRST principles of testing supported by the skill?

FIRST stands for Fast, Independent, Repeatable, Self-validating, and Timely—qualities that define effective and reliable unit tests.

Can this skill help me write better test cases?

Yes, it guides you to use the AAA (Arrange-Act-Assert) pattern and ensures you are writing tests before production code to improve overall design.

How do I start an interactive TDD session?

You can use the `/tdd` command for a general session, or specify a target like `/tdd calculateTotal` to focus on a specific function or logic.

Does this skill work with any programming language?

Yes, the TDD Assistant is language-agnostic and follows universal development standards applicable to any software environment.

What is the Red-Green-Refactor cycle guided by this skill?

It is a three-stage TDD process: first, write a failing test (Red); second, write the minimum code necessary to pass the test (Green); and third, clean up the code without changing its behavior (Refactor).

安全与测试

Guides developers through the Red-Green-Refactor cycle to ensure high-quality, test-first code implementation following FIRST principles.

The TDD Assistant skill empowers developers to adopt and master Test-Driven Development (TDD) by providing a structured, interactive workflow through the Red-Green-Refactor cycle. It ensures that tests are written before production code, validated for the correct failure reasons, and followed by minimal code implementation and clean refactoring. By integrating the FIRST principles—Fast, Independent, Repeatable, Self-validating, and Timely—this skill helps reduce bugs, improve code maintainability, and foster a disciplined development mindset across any programming language.
