SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill guides teams to adopt test-driven development (TDD) practices, ensuring features start from failing tests to drive design and prevent regressions.

Core Features & Use Cases

  • Enforces writing failing tests before implementing code.
  • Supports Red-Green-Refactor cycle for reliable progress.
  • Applies to new features, bug fixes, and refactors across projects.

Quick Start

Begin by writing a failing test for the intended behavior, then implement the minimal code to pass that test, and finally refactor for clarity.

FAQPage Schema
How do I start test-driven development for a new feature?▼

Test-driven development is a strict test-first workflow where you write a failing unit test before any production code, applicable across modern JavaScript and TypeScript projects to guide implementation and guarantee correctness.

Can I use the red-green-refactor cycle when fixing bugs?▼

Yes, the red-green-refactor cycle applies to bug fixes, new features, and refactors across modern JavaScript and TypeScript projects. You write a failing test reproducing the bug, implement the minimal fix to turn it green, and refactor safely.

Does test-driven development work with JavaScript and TypeScript projects?▼

Yes, test-driven development works across modern JavaScript and TypeScript projects. It enforces writing failing unit tests before coding, maintaining a strict red-green-refactor cycle to drive feature implementation and prevent regressions.

What happens if I skip writing a failing test before coding?▼

Skipping tests or writing production code without tests is prohibited. Test-driven development requires a failing unit test before coding to drive design, guarantee code correctness, and prevent regressions throughout feature development and refactoring.

What's the best way to maintain code quality during refactoring?▼

The best way to maintain code quality during refactoring is following the red-green-refactor cycle. Keep unit tests green before and after changes, using existing test coverage to verify behavior remains unchanged while improving code clarity.
