SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD enforces writing failing tests first to define behavior and prevent regression, leading to cleaner design and higher confidence.

Core Features & Use Cases

  • Write tests before production code to drive design and confirm expected behavior.
  • Use the RED-GREEN-REFACTOR cycle to iteratively develop features with safety rails.
  • Improve maintainability and reduce debugging time by catching regressions early.

Quick Start

Write a failing test that specifies the desired behavior, then implement the minimal code to pass the test.

FAQPage Schema
How does test-driven-development enforce writing tests before production code?▼

Test-driven-development enforces test-first discipline by requiring a failing test before any production code is written. It applies to feature development, bug fixes, and refactoring through disciplined delivery.

How do I apply the red-green-refactor cycle to feature development?▼

To apply the red-green-refactor cycle, write a failing test specifying desired behavior, implement the minimal code to pass the test, and then refactor to improve maintainability and reduce debugging time.

What is the best way to prevent regressions when refactoring software projects?▼

The best way to prevent regressions during refactoring is to use test-driven-development, catching regressions early through strict verification of behavior with automated tests to ensure higher confidence.

Does test-driven-development work for bug fixes and refactoring across software projects?▼

Yes, test-driven-development applies to feature development, bug fixes, and refactoring across software projects, ensuring disciplined delivery and strict verification of behavior through automated tests.

Why write a failing test before implementing minimal code to pass it?▼

Writing a failing test first defines the exact desired behavior and prevents regression. This leads to cleaner code design, improves maintainability, and reduces debugging time by catching issues early.
