SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD enforces writing tests first to guide development, reducing defects and regressive bugs by keeping the codebase aligned with expected behavior.

Core Features & Use Cases

  • Enforces a RED-GREEN-REFACTOR cycle to ensure tests fail before production code and only pass after minimal implementation.
  • Guides developers through test-first workflows for new features, bug fixes, and refactors, improving confidence and maintainability.
  • Provides a clear, repeatable process that teams can adopt to reduce debugging time and improve code quality in ongoing projects.

Quick Start

Write a failing test for a small behavior, then implement the minimal code to pass and refactor.

FAQPage Schema
How does test-driven development reduce software defects?

Test-driven development reduces defects by enforcing a test-first workflow, ensuring tests drive code changes and keeping the codebase aligned with expected behavior throughout feature development and refactoring.

What is the red-green-refactor cycle for testing workflows?

The red-green-refactor cycle in testing workflows ensures tests fail before production code, pass after minimal implementation, and maintain green status during subsequent code refactoring to improve maintainability.

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

To start writing tests before code, write a failing test for a small behavior, run the test suite to confirm the failure, implement the minimal code to pass, and then refactor while keeping tests green.

Can I apply test-first workflows to bug fixes and refactoring?

Yes, test-first workflows apply directly to bug fixes and refactoring across software projects, guiding developers to write failing tests first and then implement minimal code to pass them.

Why should my team adopt a TDD workflow for software engineering?

Adopting a TDD workflow provides a clear, repeatable process that reduces debugging time, improves code quality, and increases confidence in ongoing software projects by keeping tests green during changes.
