Behavior-Driven Development (BDD) Skill

This skill provides a comprehensive guide to applying Behavior-Driven Development principles to your coding tasks. BDD is not just about tools; it's a methodology for shared understanding and high-quality implementation.

How to Use This Skill

When the user asks for a feature, bug fix, or refactor, apply the following mindset:

1. Understand Behavior First: Do not start coding until you know what the system should do.
2. Define Scenarios: Create or ask for concrete examples (Gherkin) of the expected behavior.
3. Drive Implementation with Tests: Use the Red-Green-Refactor cycle.

Core Concepts

1. The BDD Cycle

The process flows from requirements to code:

• Discovery: Clarify requirements through examples (The "Three Amigos").
• Formulation: Write these examples as specific scenarios (Given/When/Then).
• Automation: Implement using TDD.
