I understand you would like to create a stub for the HTTP endpoint defined in the Swagger specification. In other words, you are looking for creating an over-the-wire test double.

There are a couple of options you have:

• Use one of the tools available on the market
  • Example of an OpenSource tool: Wiremock. You can manually configure it to simulate your HTTP APIs.
  • Example of a commercial tool: Traffic Parrot. It allows you to import Swagger definition files and create stubs that way.
• Write the stub yourself in Java. This is probably the most time-consuming option, but it allows you to be very flexible. You could build it on top of OpneSource to hit the ground running.
