How can I integrate socket.io on Karate

Question

I know that karate has a built-in support for WebSocket, but there is anyway that can use socket.io on karate?

I would like to sent a message into a microservices that comunicate with socket.io, and wait the response for asserting that the message is as expected.

No, you can't use arbitrary JavaScript libraries from Karate, and there is typically never a need to.

EDIT: if you explain what exactly you are trying to do (you can edit your question) that would make for a much more productive discussion. Karate is a testing framework. if you see a gap in the WebSockets implementation, the right thing to do is ask for a fix, see example: https://github.com/intuit/karate/issues/775

Or maybe all you need to do is use the Java inter-op. I know teams using this to test gRPC, JMS messaging and chat-bots that do bi-directional / async flows: https://twitter.com/KarateDSL/status/1128170638223364097
