Can I use this for refactoring existing code?

Yes, the skill includes a dedicated Refactor phase that encourages code cleanup only after all tests are green, ensuring functional integrity is maintained throughout the process.

What is the AAA pattern mentioned in the skill?

AAA stands for Arrange, Act, and Assert. It is a standardized way of structuring unit tests to make them more readable, maintainable, and consistent.

Does it work with standard build tools?

Yes, it integrates with common CLI tools like npm, cargo, go test, dotnet test, and gradle to run and verify tests automatically.

What programming languages does TDD Discipline support?

It supports a wide variety of environments including TypeScript (Jest/Vitest), Go, Rust (Cargo), C# (dotnet), Java (Maven/Gradle), Swift, and Python (pytest).

Why does the skill force a 'RED' phase?

The RED phase ensures that the test is valid and correctly identifies the absence of the feature or the presence of a bug before implementation begins, preventing false positives.

安全与测试

Enforces a strict test-driven development workflow using the Red-Green-Refactor cycle across multiple programming languages.

TDD Discipline is designed to maintain high code quality by mandating a rigorous test-first approach. It guides the development process through the Red-Green-Refactor cycle, ensuring that tests are written and failed before any implementation code is touched. By enforcing the Arrange-Act-Assert (AAA) pattern and providing specific templates for languages like TypeScript, Go, Rust, C#, and Java, this skill prevents common anti-patterns such as skipping the failure phase or writing implementation-heavy tests. It is an essential tool for developers aiming for high test coverage and reliable, maintainable codebases.
