Beyond the interfaces that you offer out of the box, we have some other interfaces which need to be integrated within E2E tests. Those are TCP based protocols. Is there any chance that you will make karate extendable any time soon so that we can make such calls in actions like statements and not via JS/Java API?
We would need something like
... REST API Test
And send customProtocol message(attr1=1,attr2=2)
Then expect customProtocol message(res=OK)
... GUI Test
