Creating an API Testing Tool for OpenAPI Specifications

[tschlat]

User story As a developer, I want to generate a test API so that I can test OpenAPI-specified services efficiently.

Additional context This feature request aims to provide a tool or utility that generates a test API based on an OpenAPI specification. The generated test API will allow developers to validate and verify the behavior of their services against the defined API contracts. Non-functional requirements, such as performance, scalability, and ease of use, should also be considered during the implementation.
