SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Red-Green-Refactor helps teams ensure features are designed around tests, reducing regression and guiding implementation with small, verifiable steps.

Core Features & Use Cases

  • Red-Green-Refactor Cycle: Write a failing test, implement the minimal code to pass, and refactor with clean, focused changes.
  • Atomic Commits per Phase: Each cycle yields 2–3 commits with clear scope.
  • Guided Workflow for Bugs & Features: Use TDD to drive both new features and bug fixes when tests define behavior.

Quick Start

Write a failing test, implement the simplest code to pass it, then refactor 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 workflow where you write a failing test, implement the minimal code to pass it, then refactor while keeping tests green. This cycle ensures features are designed around tests with small, verifiable steps.

How do I use test-driven development for bug fixes and feature implementation?

You can use test-driven development for bug fixes and feature implementation by writing a test that defines the expected behavior, implementing the simplest code to pass, and refactoring cleanly with atomic commits per phase.

Can I use atomic commits for each phase of a red-green-refactor cycle?

Yes, atomic commits per phase are enforced during the red-green-refactor cycle. Each cycle yields 2–3 commits with clear scope, ensuring strict adherence to the test-first approach and explicit verification of refactors.

When should I use a test-first approach for software engineering?

You should use a test-first approach for software engineering when you need to reduce regression and guide implementation with small, verifiable steps. It applies to feature implementation, bug fixes, and design-driven development where tests define behavior.

What's the best way to start writing a failing test for new features?

The best way to start writing a failing test is to define the expected behavior first, implement the simplest code to pass it, then refactor while keeping tests green. This ensures features are designed around tests from the beginning.
