SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps teams ensure new features are built with verified behavior by requiring tests before implementation.

Core Features & Use Cases

  • Red-Green-Refactor workflow drives incremental delivery and refactoring safety.
  • Test-first discipline reduces regressions and clarifies expected behavior.
  • Use Case: When adding a new feature or fixing a bug, write a failing test first, then implement the minimal code to pass and refactor.

Quick Start

  • Write a failing test that captures the desired behavior.
  • Implement the smallest amount of production code to make the test pass.
  • Refactor the code while keeping tests green, ensuring the behavior stays correct.

FAQPage Schema
What is the test-first development workflow for reliable feature work?▼

The test-first workflow requires writing a failing test that captures desired behavior, implementing minimal production code to pass, and refactoring while keeping tests green. This ensures verified behavior before implementation.

How do I implement a new feature using the red-green-refactor cycle?▼

To implement features using red-green-refactor, write a failing test first, run it to confirm failure, implement the smallest amount of code to pass, then refactor for clarity while keeping tests green.

When should I use test-driven development for bug fixes and refactoring?▼

Use test-driven development for bug fixes and refactoring to ensure behavior is verified before code is written. This test-first discipline reduces regressions and clarifies expected behavior across software projects.

Do I need standard testing frameworks to drive development with TDD?▼

Yes, you need standard testing frameworks to drive development with TDD. These frameworks are required to write failing tests first, run them to confirm failure, and verify minimal code implementation passes.

What is the best way to reduce regressions when adding new software features?▼

The best way to reduce regressions is adopting a test-first discipline. By writing failing tests before code and driving development with the red-green-refactor cycle, you clarify expected behavior and ensure reliable delivery.
