SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Streamline the adoption of Test-Driven Development by guiding teams through test-first design, reducing risk and design drift.

Core Features & Use Cases

  • Guided Red-Green-Refactor workflow with prompts for test design, failing tests, and incremental refactoring.
  • Supports unit and integration test planning with Arrange-Act-Assert scaffolding and test double recommendations.
  • Encourages consistent test coverage during features, bug fixes, and refactors across software projects.

Quick Start

Run the Red-Green-Refactor cycle on a small feature to validate tests first and drive implementation.

FAQPage Schema
How do I apply test-driven development to my software engineering projects?

Test-driven development is applied through a guided Red-Green-Refactor workflow that prompts test design, generates failing tests first, and drives incremental refactoring to ensure software quality and reduce design drift.

What is the Arrange-Act-Assert pattern in unit testing?

The Arrange-Act-Assert pattern is a test scaffolding structure that organizes unit and integration tests into clear setup, execution, and validation phases, ensuring consistent test coverage across software features and bug fixes.

Do I need a specific scripting environment to start writing failing tests first?

You need a clear scripting environment and test scaffolding to generate failing tests and validate green results. The ability to mock external dependencies is also required to isolate units for integration testing.

When should I not use a test-first workflow for refactoring?

A test-first workflow is not recommended when you lack a clear scripting environment or cannot mock external dependencies, as validating green results during refactoring requires reliable test doubles and Arrange-Act-Assert scaffolding.
