What is the AAA pattern mentioned in the skill?

AAA stands for Arrange, Act, and Assert. It is a pattern that organizes tests into three distinct blocks: preparing the data, executing the target method, and verifying the result.

Can I use this skill for bug fixing?

Yes. The skill encourages writing a failing test case that reproduces the bug (Red) before writing any code to fix it, ensuring the bug is truly resolved and won't regress.

What is the TDD Wada Style skill?

It is a specialized capability for Claude Code that implements the Test-Driven Development philosophy of Takuto Wada, focusing on the Red-Green-Refactor cycle and behavioral testing.

How does this skill help with refactoring?

It ensures that you have a 'Green' test state before you begin, then guides you through structural improvements while ensuring that the external behavior remains unchanged and the tests stay passing.

安全与测试

Implements high-quality software using the Red-Green-Refactor cycle and behavior-driven test patterns inspired by Takuto Wada's philosophy.

关于

This skill integrates Takuto Wada’s (t.wada) renowned TDD philosophy into Claude’s coding workflow, treating tests as a design tool rather than just a verification step. It guides the development process through the disciplined Red-Green-Refactor cycle, enforces the Arrange-Act-Assert (AAA) structure, and prioritizes testing behavior over implementation details. This approach ensures that your codebase remains maintainable, provides living documentation through tests, and achieves high reliability through rigorous boundary and error-case coverage.
