SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill codifies the Test-Driven Development workflow, transforming a best-practice approach into a practical, repeatable guide that reduces defects and accelerates design.

Core Features & Use Cases

  • Structured RED-GREEN-REFACTOR cycle to guide development from failing tests to working code.
  • Design-focused benefits: better interfaces, incremental improvements, and safer refactoring.
  • Use Case: Apply TDD to new features, bug fixes, and API design across OO and procedural codebases.

Quick Start

Follow the RED-GREEN-REFACTOR cycle to practice TDD:

  • Write a failing test that defines the desired behavior.
  • Implement the minimal code to pass the test.
  • Refactor the code to improve structure while keeping tests green.
  • Repeat for the next behavior or feature.

FAQPage Schema
What is the RED-GREEN-REFACTOR cycle in test-driven development?▼

Test-driven development improves software design by defining desired behavior through failing tests first, which naturally drives better interfaces and incremental structural improvements.

How do I start practicing test-driven development for a new feature?▼

To start practicing test-driven development for a new feature, write a failing test defining the desired behavior, implement minimal code to pass, refactor, then repeat for the next feature.

Can I apply test-driven development to procedural codebases?▼

Yes, you can apply test-driven development to procedural codebases. The RED-GREEN-REFACTOR workflow supports both object-oriented and procedural code for unit-level testing and design.

Does test-driven development work for API design and bug fixes?▼

Test-driven development works for API design and bug fixes across object-oriented and procedural codebases, using the structured RED-GREEN-REFACTOR cycle to guide development and reduce defects.
