SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Reduces the risk of bugs by forcing a failing test before implementing code, ensuring intended behavior is validated early.

Core Features & Use Cases

  • Red-Green-Refactor workflow with small, test-driven iterations.
  • Encourages writing tests first for new features, bug fixes, and refactors.
  • Use case: implement a function by driving design with failing tests and verifying behavior.

Quick Start

Write a minimal failing test for a simple behavior, then implement just enough code to pass and finally refactor for clarity.

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

Test-driven development uses the red-green-refactor cycle to drive reliable code by first writing a failing test, implementing minimal production code to pass it, and then refactoring for clarity without changing behavior.

How do I implement a new feature using test-driven development?▼

To implement a new feature using test-driven development, write a minimal failing test that defines the intended behavior, write just enough code to make it pass, and iterate with small test-driven steps to prevent defects early.

Can I use test-driven development for bug fixes and refactoring?▼

Yes, test-driven development applies to bug fixes and refactoring by enforcing a failing test before implementing any changes, ensuring the intended behavior is validated and preventing regressions across software engineering projects.

Does test-driven development require writing tests before any production code?▼

Yes, test-driven development enforces writing a failing test before implementing production code, ensuring intended behavior is validated early and requiring only minimal code to pass the test.

What's the best way to start a test-driven development workflow?▼

The best way to start a test-driven development workflow is to write a minimal failing test for a simple behavior, implement just enough code to pass, and refactor for clarity to drive design with disciplined test maintenance.
