SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This approach guides teams to write tests before implementation, preventing regressions and guiding clean design.

Core Features & Use Cases

Red-Green-Refactor cycle: write a failing test, implement code, refactor for clarity.
Behavior-driven discipline: keeps tests in sync with requirements and prevents overfitting.
Applicable to features, bug fixes, and refactors across projects of any size.

Quick Start

Describe a feature, write a failing test first, then implement just enough code to pass.

FAQPage Schema

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

The red-green-refactor cycle in test-driven development means writing a failing test, implementing just enough code to pass it, and then refactoring for clarity. This enforces test-first development to prevent regressions and guide clean design.

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

To start writing tests before implementation, you describe the feature, write a failing test first, and then implement just enough code to pass. This test-first workflow keeps tests in sync with requirements and prevents overfitting.

Can I apply test-driven development to refactors and bug fixes?▼

Yes, you can apply test-driven development to refactors and bug fixes across codebases of varying sizes. It guides teams to write failing tests before code and maintain green tests throughout the refactoring process.

Why does behavior-driven discipline matter in software testing?▼

Behavior-driven discipline matters in software testing because it keeps tests in sync with requirements and prevents overfitting. This ensures clear, minimal tests fail first and validate actual behavior rather than implementation details.

When should I not write production code without a failing test?▼

You should never write production code without a failing test when following this development workflow. It strictly enforces writing failing tests before code to prevent regressions and ensure every feature has clear requirements.
