Can this skill help with bug fixing?

Absolutely. The skill requires reproducing the bug with a failing test case before any implementation logic is touched, ensuring the fix actually works.

What is the Red-Green-Refactor cycle in this skill?

It is a three-step process where you write a failing test first (Red), implement the minimum code to pass (Green), and then optimize the code structure without changing behavior (Refactor).

When should I avoid using the TDD skill?

TDD is typically skipped for simple UI styling tweaks, configuration file changes, or documentation updates where logic is not being modified.

Does this skill work with both frontend and backend?

Yes, it includes specific patterns for backend development (like Elixir/Mix) and frontend development (like TypeScript/Yarn).

Why does the skill insist on tests failing first?

Ensuring a test fails first verifies that the test is valid and capable of catching the error it was designed to prevent, avoiding false positives.

安全与测试

Enforces the Red-Green-Refactor cycle to ensure robust software development through failing tests before implementation.

关于

The Test-Driven Development skill empowers Claude to follow professional software engineering standards by implementing the strict Red-Green-Refactor cycle. It ensures that every new feature, bug fix, or refactor begins with a failing test case to verify the requirement, followed by the minimal code necessary to pass, and finally a cleanup phase. This methodology reduces bugs, prevents regressions, and produces cleaner, more maintainable codebases across various environments including Elixir and TypeScript.
