SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers write robust code by ensuring that every piece of functionality is verified by automated tests before and during its development, preventing bugs and improving code quality.

Core Features & Use Cases

  • Test-Driven Development Workflow: Guides users through the red-green-refactor cycle.
  • Integration Testing Focus: Emphasizes testing through public interfaces rather than implementation details.
  • Use Case: When starting a new feature, use this Skill to define the expected behavior with a failing test, then write the minimal code to make it pass, and finally refactor.

Quick Start

Follow the red-green-refactor cycle to develop new features or fix bugs.

FAQPage Schema
How do I start test-driven development for a new software feature?

Test-driven development starts by writing a failing integration test that defines expected behavior through public interfaces, then writing minimal code to pass it, and finally refactoring.

What is the red-green-refactor cycle in software development?

The red-green-refactor cycle is a test-driven development workflow where you write a failing test, implement the minimal code to make it pass, and then refactor the code to improve quality.

Should I write integration tests for implementation details or public interfaces?

Integration tests should verify behavior through public interfaces rather than testing implementation details, ensuring robust software tests that prevent bugs and improve code quality.

How can I fix bugs using test-driven development?

To fix bugs using test-driven development, define the expected behavior with a failing integration test that exposes the bug, then write the software code required to make the test pass.

When do I need to refactor code during the test-driven development workflow?

Refactoring code is needed during the final stage of the test-driven development cycle, after writing minimal code to pass the integration test, to improve structure and create deep modules.

Can I use test-driven development to build deep modules and testable interfaces?

Test-driven development supports creating deep modules and testable interfaces by emphasizing integration tests that verify software behavior through public interfaces instead of implementation details.
