SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Ensures code correctness by forcing tests to drive development, preventing regressions and unclear requirements from slipping into production.

Core Features & Use Cases

  • Red-Green-Refactor workflow: write a failing test, implement minimal code to pass, then refactor while keeping tests green.
  • Behavior-first design: ensures APIs meet real-world expectations by codifying them in tests before implementation.
  • Broad applicability: suitable for feature development, bug fixes, and refactoring across software projects.

Quick Start

Write a failing test for the intended behavior, then implement the minimal code to pass it.

FAQPage Schema
How does test-driven development guarantee code correctness?

Test-driven development guarantees correctness by forcing you to write failing tests for intended behavior before implementing minimal code, preventing unclear requirements and regressions from reaching production.

What is the red-green-refactor workflow in software engineering?

The red-green-refactor workflow involves writing a failing RED test, implementing minimal code to pass it as GREEN, and then refactoring while maintaining green tests to ensure behavior remains correct.

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

Apply test-driven development to bug fixes and refactoring by first writing a failing test that captures the expected behavior, then changing the minimal code required to pass that test before refactoring.

When should I use test-driven development in my software project?

Use test-driven development across software projects for feature development, bug fixes, and refactoring to ensure APIs meet real-world expectations by codifying requirements in tests before implementation.

How do I write a failing test for intended behavior before implementation?

Write a failing test for intended behavior by codifying real-world API expectations into a test case, run it to observe the RED failure, and then implement the minimal code required to turn it GREEN.
