How to Test Asynchronous WS, built using KAFKA.... any method apart from Mock service

Hi Team,

 

I have to do POC on Asynchronous service which are built using KAFKA in my project.

I am not able to get how can we start with that, firstly if KAFKA can be tested from SOAP ui?

 

Next, how shall i proceed with testing of asynchronous service as i am confused.

When try for mock service, my project dont have port and all details.

 

Please help.
