SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill enforces a rigorous test-first development workflow, ensuring code quality, maintainability, and correctness by preventing the introduction of bugs before they are written.

Core Features & Use Cases

Strict Test-First Workflow: Mandates writing failing tests before any production code.
RED->GREEN->REFACTOR Cycle: Guides development through a proven, iterative process.
Use Case: When tasked with implementing a new user authentication feature, this Skill ensures that comprehensive tests are written first, verifying each aspect of the authentication flow before any implementation code is committed.

Quick Start

Follow the TDD workflow to implement the new feature.

FAQPage Schema

How does the test-driven development RED-GREEN-REFACTOR cycle work?▼

The test-driven development RED-GREEN-REFACTOR cycle enforces writing a failing test, writing production code to pass it, then refactoring. This strict test-first workflow ensures code quality, maintainability, and correctness by preventing bugs before implementation.

How do I implement test-first development for a new software feature?▼

To implement test-first development, you must mandate writing failing tests before any production code. This methodology guides you through an iterative verification process, ensuring comprehensive tests verify each aspect of the feature flow before implementation code is committed.

Why should I use strict test-driven development for code quality and verification?▼

You should use strict test-driven development to enforce a rigorous test-first workflow, ensuring code quality and correctness. By prioritizing test creation before production code, it prevents the introduction of bugs and maintains code integrity through specific verification steps.

What testing anti-patterns does this test-driven development methodology address?▼

This test-driven development methodology addresses testing anti-patterns and applies anti-rationalization rules to maintain code integrity. It enforces strict verification steps and output requirements throughout the RED-GREEN-REFACTOR cycle, preventing common TDD workflow failures.
