SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill codifies the red-green-refactor loop to drive disciplined testing, reduce defects, and improve code maintainability across software projects.

Core Features & Use Cases

  • Enforces red-green-refactor cycle to guide feature development and bug fixes.
  • Emphasizes the Arrange-Act-Assert testing pattern for clear, scoped tests.
  • Provides guardrails for incremental refactoring and safe code improvement.

Quick Start

Begin by writing a failing test for the intended behavior, then implement the minimal code to pass, and finally refactor.

FAQPage Schema
What is test-driven development and how does the red-green-refactor loop work?

Test-driven development (TDD) is a software engineering process that enforces a red-green-refactor loop. You first write a failing test for intended behavior, implement minimal production code to pass it, and then safely refactor to improve maintainability.

How do I apply the AAA testing pattern for new feature development?

To apply the Arrange-Act-Assert (AAA) testing pattern for feature development, you structure tests into three clear phases: set up data, execute the behavior, and verify outcomes. This ensures clear, scoped tests within the TDD cycle.

Can I use test-driven development for bug fixes and exploratory work?

Yes, you can use test-driven development for bug fixes and exploratory work. The red-green-refactor loop provides clear guardrails to drive reliable software, ensuring you write failing tests that reproduce defects before implementing minimal code to fix them.

What's the best way to ensure safe incremental refactoring in software engineering?

The best way to ensure safe incremental refactoring is to follow the TDD workflow. By maintaining comprehensive tests validated through the red-green-refactor loop, you gain guardrails to safely improve code structure without introducing new defects.

When should I not use test-driven development for my software project?

You should not use test-driven development when minimal production code and structured test-first constraints hinder rapid prototyping. TDD enforces strict red-green-refactor cycles, which may introduce friction during early exploratory work where immediate feedback outweighs test coverage.
