How does it handle requirements traceability?

It maps every generated test case directly to specific Requirement IDs (REQ-*) and Business Rules (BR-*) in both the code comments and the git commit messages.

Does this skill write the implementation code?

No, this skill specifically handles the RED phase. The implementation (writing code to make tests pass) is handled in the subsequent GREEN phase.

Why must the tests fail initially?

Failing tests confirm that the test suite is correctly configured and that the test is actually checking for the desired behavior rather than passing by accident or due to existing code.

What is the 'RED' phase in TDD?

The RED phase is the first step in the Test-Driven Development cycle where you write a test for a new requirement and watch it fail because the functionality hasn't been implemented yet.

Which programming languages does this skill support?

This skill includes optimized templates and directory logic for Python (pytest), TypeScript/JavaScript (Jest), and Java (JUnit).

セキュリティとテスト

Automates the initial stage of Test-Driven Development by generating failing test cases from requirements before implementation begins.

概要

The TDD Red Phase skill guides Claude through the crucial first step of the Test-Driven Development cycle. It parses business requirements and technical constraints to draft comprehensive test suites for Python, TypeScript, or Java projects. By ensuring tests fail before any code is written, it validates the test's ability to catch regressions and forces a clear definition of API design and expected behavior, establishing a solid foundation for the subsequent implementation and refactoring phases.

主な機能
