Which programming languages does this skill support?

While it provides general TDD principles for any language, it includes deep, specialized guidance and references for Python (pytest/unittest) and Emacs Lisp (ERT/Buttercup).

How does this skill help with code refactoring?

It enforces the 'Refactor Only When Green' rule, ensuring you have a safety net of passing tests before making changes, and provides templates for common refactoring patterns to minimize technical debt.

Does it support Arrange-Act-Assert (AAA) patterns?

Yes, the skill actively promotes the AAA and Given-When-Then patterns to ensure your tests are readable, structured, and serve as effective documentation for your code's behavior.

What is the Red-Green-Refactor cycle?

It is the core TDD workflow: first, write a failing test (Red); second, write the minimal code necessary to make that test pass (Green); third, improve the code's structure and quality while ensuring tests stay passing (Refactor).

安全与测试

Guides developers through the Red-Green-Refactor cycle to implement robust, test-first code across multiple programming languages.

关于

The TDD skill facilitates a disciplined Test-Driven Development workflow, helping users write tests before implementation to ensure high code quality and reliability. It provides structured guidance on the Red-Green-Refactor cycle, enforces best practices like Arrange-Act-Assert (AAA), and offers language-specific patterns for Python and Emacs Lisp. Whether you are building new features from scratch or refactoring legacy systems, this skill ensures that every line of code is verified and every requirement is met through a test-first approach.
