How does the 'Baby Steps' approach help development?

Baby Steps involves making the smallest possible changes in 2-minute cycles. This localizes errors immediately and ensures the codebase is always only seconds away from a 'Green' passing state.

What is the RGRC cycle in this skill?

RGRC stands for Red-Green-Refactor-Commit. It is a systematic TDD workflow that ensures every feature is tested first, implemented minimally, cleaned up, and then committed in a stable state.

What test design techniques are included?

The skill uses Equivalence Partitioning to group similar inputs, Boundary Value Analysis to test edge cases, and Decision Tables to map complex logical combinations.

Can I use this skill for existing codebases?

Yes, it is highly effective for creating a test safety net before refactoring existing code or for adding missing coverage to legacy logic.

What are the recommended coverage targets?

The skill follows industry best practices, aiming for at least 80% Statement Coverage (C0) and 70% Branch Coverage (C1) to balance quality with development velocity.

セキュリティとテスト

Implements a comprehensive Test-Driven Development (TDD) workflow using RGRC cycles, Baby Steps, and systematic test design techniques.

概要

This skill empowers Claude to follow a rigorous Test-Driven Development (TDD) workflow, incorporating the Red-Green-Refactor-Commit (RGRC) cycle and t_wada's 'Baby Steps' approach. It provides a structured framework for generating high-quality test cases using industry-standard techniques like equivalence partitioning, boundary value analysis, and decision tables. Ideal for developers aiming for high code coverage and a reliable safety net during refactoring, this skill ensures that every line of code is purposeful, verifiable, and maintainable.
