SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD provides a disciplined approach to software development by ensuring tests drive design and verify behavior before production code.

Core Features & Use Cases

  • Red-Green-Refactor cycle: write a failing test first, implement minimal code to pass, then refactor while keeping tests green.
  • Regression safety: prevents regressions by requiring tests for new features and bug fixes.
  • Design guidance: encourages modular, testable interfaces and clearer requirements.

Quick Start

Start by writing a small failing test for a simple behavior, implement just enough code to pass it, then refactor to improve structure while keeping tests green.

FAQPage Schema
What is test-driven development and how does the red-green-refactor cycle work?▼

Test-driven development is a software testing discipline where you write a failing test first, implement minimal code to pass it, then refactor to improve structure while keeping tests green. This cycle ensures correct behavior and maintainable code.

How do I start writing tests before production code for a new feature?▼

Start test-driven development by writing a small failing test for a simple behavior. Implement just enough production code to make it pass, then refactor the implementation while keeping the tests green.

When should I use test-first development for bug fixes and behavioral changes?▼

Use test-first development during bug fixes and behavioral changes to prevent regressions. Writing a failing test before coding verifies the corrected behavior and provides automated regression protection across software projects.

Does test-driven development require specific testing frameworks or dependencies?▼

No specific testing frameworks or dependencies are required. Test-driven development provides a discipline-agnostic methodology applicable across software projects and teams requiring automated regression protection and modular design.

How does writing tests first improve software design and maintainability?▼

Writing tests first improves software design by encouraging modular, testable interfaces and clearer requirements. This test-driven approach ensures production code is guided by behavior verification, resulting in maintainable software.
