SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill eliminates the uncertainty and manual overhead of implementing test-driven development, ensuring you consistently follow proven TDD practices that prevent bugs and improve code quality.

Core Features & Use Cases

  • Red-Green-Refactor Cycle Management: Guides you through the complete TDD workflow with automated step-by-step instructions.
  • Quality Standards Enforcement: Maintains 80%+ code coverage and integrates with linting/type checking tools.
  • Use Case: When building a new feature for your web application, use this Skill to systematically write failing tests first, implement minimal working code, and refactor safely with full test coverage.

Quick Start

Activate this skill when starting a new feature implementation and say: "Help me implement user authentication using TDD starting with writing the first failing test."

FAQPage Schema
How do I implement test-driven development to catch bugs earlier?

Test-driven development (TDD) is a practice where you write failing tests first, then implement minimal code to pass them, then refactor safely. This Skill guides you through the Red-Green-Refactor cycle, enforcing 80%+ code coverage and quality gates to prevent bugs before they reach production.

What's the best way to structure tests in my codebase?

This Skill enforces explicit test placement rules: store tests under `src/__tests__/` or alongside implementation files as `*.test.ts(x)`. Combined with mandatory linting and type checking before commits, this structure ensures consistent test organization and code quality across your project.

How do I maintain code coverage standards while refactoring?

TDD with this Skill ensures you maintain a minimum 80%+ code coverage target throughout refactoring. The Red-Green-Refactor workflow keeps tests passing at each step, so you refactor with confidence that existing functionality remains intact.

Can I automate quality checks before committing code?

Yes. This Skill integrates lint and type-checking tools as mandatory quality gates before commits, automating enforcement of code standards. Combined with test coverage requirements, this prevents low-quality code from entering your repository.

When should I use TDD for feature development?

Use TDD when building new features, implementing bug fixes, or adding product capabilities where code quality and maintainability matter. This Skill is most effective during active development when you want to systematically plan, test, and validate each requirement.

Do I need prior testing experience to follow TDD workflows?

This Skill guides developers through complete TDD workflows step-by-step, eliminating manual overhead and uncertainty. You learn the Red-Green-Refactor pattern by doing, with automated instructions supporting each phase of test-first development.
