SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps ensure software quality by enforcing a test-first approach: you write tests before implementing code, reducing regressions and guiding design.

Core Features & Use Cases

  • Test-first workflow: write failing tests, then implement minimal code to pass.
  • Red-Green-Refactor cycle: follow the TDD loop with quick feedback.
  • Safe refactoring: confidence to refactor with tests in place.

Quick Start

  • Create a failing test for a small feature, then implement the minimal code to pass.

FAQPage Schema
What is test-driven development and how does it improve software quality?▼

Test-driven development enforces a test-first workflow where you write failing tests before implementation, reducing regressions and guiding design to guarantee software quality and correct behavior.

How do I apply the red-green-refactor cycle when implementing new features?▼

Apply the red-green-refactor cycle by writing a failing test, implementing minimal production code to pass it, and then safely refactoring the code with quick feedback from the tests.

Does test-driven development work for bug fixes and refactoring existing code?▼

Yes, test-first development is applicable during bug fixes and refactoring. You write a failing test capturing the desired behavior change, then implement minimal code to pass and ensure safe refactoring.

How do I start unit testing with a test-first approach in my software projects?▼

Start unit testing with a test-first approach by creating a failing test for a small feature, then writing the minimal production code required to make that unit test pass.

Why should I write tests before code instead of adding them afterwards?▼

Writing tests before code ensures immediate feedback through the red-green-refactor loop, reduces regressions, and guides software design by focusing on correct behavior upfront.
