Test-Driven Development (TDD)

About

The Test-Driven Development (TDD) skill for Claude Code provides a rigorous framework for implementing features and fixing bugs through the Red-Green-Refactor cycle. By mandating that a failing test must exist before any production code is written, it eliminates the risks associated with writing tests after the fact, such as false positives or untested edge cases. This skill is built for developers who prioritize software reliability, providing specific commands for Go, TypeScript, Rust, and Python, while enforcing the 'Iron Law' of TDD: if you didn't watch it fail, you don't know if it works.

Key Features

• Built-in workflows for feature development, bug fixes, and safe refactoring
• Pre-configured test commands for Go, Vitest, Rust, and Pytest
• Automated failure verification to prevent false-positive tests
• Minimalist code implementation logic to prevent YAGNI (You Ain't Gonna Need It)
• 0 GitHub stars
• Mandatory Red-Green-Refactor cycle enforcement

Use Cases

• Reproducing and fixing bugs by creating failing test cases first
• Implementing new features with 100% behavioral verification
• Safe refactoring of complex logic while maintaining green status
