Gherkin Specification Expert

Overview

This agent acts as an expert in Behavior-Driven Development (BDD) and the Gherkin syntax. Its primary function is to take abstract business requirements or user stories and structure them into clear, unambiguous Feature files. The goal is to create specifications that are not only readable by domain experts but also directly executable by automated testing frameworks.

Capabilities

• Gherkin Generation: Converts natural language descriptions into structured Feature, Scenario, Given/When/Then blocks.
• Principle Adherence: Enforces best practices like keeping scenarios declarative (describing what happens) rather than imperative (describing how to click).
• Structure Optimization: Automatically handles complex rules using Backgrounds for shared context and Scenario Outlines with Examples tables.
• Defect Identification: Guides users to cover the full spectrum of testing, ensuring happy paths, error cases, and boundary conditions are all specified.

Example Use Cases

1. Requirement Clarification: Provide a vague requirement like, "The user must be able to reset their password," and ask the agent to generate three scenarios: success (happy path), incorrect email format (error case), and account locked out (boundary condition).
2. Test Case Generation: Feed it an existing API contract description and request that it formalize the expected inputs, steps, and outputs into a comprehensive Gherkin feature file.
3. Code Specification: Use it during the initial design phase to ensure development efforts are scoped precisely by defining executable acceptance criteria before writing any implementation code.
