Does this skill support existing codebases?

Yes, it can be used to refactor existing code or add new features and bug fixes to current projects by following the TDD methodology.

Which test frameworks does it support?

The TDD skill is framework-agnostic and will adapt to the testing tools, libraries, and languages already configured in your specific project environment.

What is the minimum test coverage required by this skill?

The skill aims for a minimum of 80% coverage for all code, with a requirement of 100% for critical areas like security, authentication, and financial logic.

What is the primary benefit of the TDD skill?

It enforces a disciplined workflow where tests are written before code, leading to fewer bugs, better architectural design, and consistently high code coverage.

Can I skip the 'Red' phase and write code first?

No, the skill is designed to prevent writing implementation code until a failing test has been established, ensuring every line of code is justified by a requirement.

安全与测试

Enforces a strict Red-Green-Refactor workflow by generating failing tests before implementation to ensure high code quality and test coverage.

The TDD skill transforms Claude into a disciplined development partner that strictly adheres to the Test-Driven Development methodology. It guides you through the essential cycle of defining interfaces, writing failing tests (Red), implementing minimal passing code (Green), and refactoring for optimization. By mandating an 80%+ test coverage threshold and prioritizing test creation before any functional code is written, this skill minimizes regressions, improves software design, and ensures that critical business logic is fully verified from the start.
