The OpenAPI Mock Server is located in the test package in the `port_http_server` module and it depends upon the `swagger-parser` library, so to use it you need to add the following dependencies
```implementation("com.hexagonkt:port_http_server:1.3.4:test")
implementation("io.swagger.parser.v3:swagger-parser:2.0.24")```
and you should be able to create it. Thanks for pointing this out, I will update the docs to mention the required dependencies. Please let me know if you face any other issues.
