SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development ensures you write failing tests before implementing code, preventing regressions and improving design.

Core Features & Use Cases

  • Red-Green-Refactor cycle: write a failing test, implement minimal code to pass, refactor for clarity.
  • Guardrails for production: enforces test-first discipline for features, bug fixes, and refactors.

Quick Start

Follow the Red-Green-Refactor cycle on every change to validate behavior before shipping.

FAQPage Schema
What is the red-green-refactor cycle in test-driven development?▼

The red-green-refactor cycle in test-driven development involves writing a failing test, implementing minimal code to pass it, then refactoring for clarity to ensure robust design and maintainability.

How do I apply test-first development to bug fixes and refactoring?▼

Apply test-first development to bug fixes and refactoring by enforcing mandatory failing tests before implementing minimal code changes, ensuring code correctness and preventing regressions across your codebase.

Does test-driven development work for both frontend and backend codebases?▼

Yes, test-driven development works for both frontend and backend codebases, applying the test-first workflow to feature development, bug fixes, and refactors to validate behavior before production.

Why should I write failing tests before implementing production code?▼

Write failing tests before implementing production code to enforce test-first discipline, prevent regressions, improve software design, and ensure code correctness before shipping features.

What is the best way to ensure code correctness before shipping to production?▼

The best way to ensure code correctness before production is applying the test-driven development workflow, which mandates failing tests and minimal implementations to validate behavior across all changes.
