SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Catch bugs as soon as they are introduced by enforcing a test-first workflow that ensures code correctness before implementation.

Core Features & Use Cases

Red-Green-Refactor Cycle: Write a failing test, implement the minimal code, and refactor with confidence.
Quality Assurance: Promotes better design, test coverage, and safer refactors during feature development and bug fixes.
Use Case: When starting a new feature or fixing a bug, use this skill to drive the development with tests first and verification steps.

Quick Start

Run a failing test, then implement the minimal production code to make it pass.

FAQPage Schema

How do I apply test-driven development to catch bugs while writing code?▼

Test-driven development catches bugs by enforcing a test-first workflow, where you write a failing test before implementing code to validate behavior. You run the test, implement minimal production code to pass it, and then refactor with confidence.

What is the red-green-refactor cycle in test-driven development?▼

The red-green-refactor cycle in test-driven development is a workflow where you first write a failing test, then implement the minimal production code to make it pass, and finally refactor the code while ensuring all tests still pass.

How do I use test-driven development for bug fixes and refactoring?▼

Test-driven development for bug fixes and refactoring involves writing a test that reproduces the bug or validates existing behavior before changing code. This ensures safer refactors and better test coverage across projects of varying sizes.

Does test-driven development work for projects of varying sizes?▼

Test-driven development works for projects of varying sizes by driving feature development and bug fixes with tests first and verification steps. The red-green-refactor cycle ensures correctness before implementation regardless of project scale.

Why should I write tests before code instead of after implementation?▼

Writing tests before code ensures correctness by validating behavior upfront rather than retrofitting tests to existing implementation. This test-first workflow promotes better design, improves test coverage, and enables safer refactoring during feature development.

What's the best way to start test-driven development for a new feature?▼

The best way to start test-driven development for a new feature is to run a failing test first, then implement the minimal production code to make it pass. This enforces a verification checklist and ensures code correctness before full implementation.
