SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This approach enforces a test-first workflow, preventing production code from being written without validating behavior first, thus reducing regressions and improving reliability.

Core Features & Use Cases

  • Enforces the RED-GREEN-REFACTOR cycle to ensure tests drive implementation.
  • Guides feature development, bug fixes, and refactoring with a verification loop.
  • Helps teams communicate intent and guard against scope creep through automated tests.

Quick Start

Write a failing test first, then implement the minimal production code to pass it.

FAQPage Schema
What is test-driven development and how does it improve software quality?▼

Test-driven development is a tests-first workflow that enforces writing failing tests before production code, reducing regressions and improving reliability by validating behavior upfront.

How do I implement the red-green-refactor cycle for feature development?▼

To implement the red-green-refactor cycle, write a failing test first, then write minimal production code to pass it, and finally refactor while keeping tests green.

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

Yes, you can apply test-driven development during bug fixes and refactoring to ensure changes are validated by tests before coding, maintaining a strict verification loop.

Why does test-driven development prohibit writing production code without tests?▼

Test-driven development prohibits production code without tests to prevent unvalidated behavior, guard against scope creep, and ensure automated tests define intent before implementation begins.

What's the best way to start a test-first workflow for a new feature?▼

The best way to start a test-first workflow is to write at least one failing test defining the expected behavior, then implement the minimal code required to pass it.

Does test-driven development require specific testing frameworks to work?▼

No, test-driven development enforces a workflow rather than requiring specific frameworks, allowing you to apply the red-green-refactor cycle across any software engineering environment.
