What is 'Triangulation' in TDD?

Triangulation is the practice of adding a second test case to force the implementation to move from a hardcoded value to a generalized algorithm.

Can I use this for refactoring existing code?

Yes, the skill provides a workflow for establishing a 'Green' state before refactoring, ensuring that internal changes do not alter external behavior.

Is this skill specific to TypeScript?

While the principles apply generally, the provided implementation patterns and examples are optimized for TypeScript and pnpm environments.

How does this skill help with test naming?

It provides rules for creating clear, descriptive test names that act as documentation, replacing vague names with specific behavioral expectations.

What is the t-wada style of TDD?

It is a specific methodology that emphasizes the Red-Green-Refactor cycle, incremental baby steps, and triangulation to ensure code is both functional and maintainable.

Implements rigorous Test-Driven Development using the Red-Green-Refactor cycle, triangulation, and baby-step methodologies.

This skill integrates the renowned 't-wada' style of Test-Driven Development (TDD) into your development workflow, guiding Claude to prioritize tests before implementation. It enforces the classic Red-Green-Refactor cycle, ensuring that code is built incrementally through 'baby steps' and generalized through 'triangulation.' By focusing on intent-revealing tests and minimal implementations, it helps developers create robust, well-documented, and highly maintainable TypeScript codebases while avoiding over-engineering.
