SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps teams ensure code changes don’t introduce regressions by enforcing a test-first approach, driving safer software delivery.

Core Features & Use Cases

  • Red-Green-Refactor workflow: Write failing tests first, then implement minimal code to pass tests, then refactor.
  • Regression protection: Automatically validates existing behavior remains intact during features and fixes.
  • Practical scenarios: Use for new features, bug fixes, or refactors to maintain code quality across releases.

Quick Start

Start by writing a failing test that captures the desired behavior, then implement the minimal code to pass the test and refactor for clarity.

FAQPage Schema
How does test-driven development prevent regressions during refactoring?▼

Test-driven development prevents regressions by requiring a failing test before any code implementation, automatically validating that existing behavior remains intact during refactors and bug fixes.

What is the Red-Green-Refactor cycle in TDD?▼

The Red-Green-Refactor cycle in TDD is a workflow where you write a failing test first, implement minimal code to pass the test, then refactor the code for clarity.

How do I write tests first for new software features?▼

To write tests first for new software features, start by writing a failing test that captures the desired behavior, then implement the minimal code required to pass the test.

Can I apply test-first development to both bug fixes and new features?▼

Yes, you can apply test-first development to bug fixes, new features, and refactors across software projects that rely on automated tests to validate behavior.

Do I need automated tests to use test-driven development?▼

Yes, test-driven development requires automated tests to validate behavior and ensure code changes do not introduce regressions across software releases.
