How to do functional automation for websocket based application?

Question

My Application Under Test is a WebSocket based application.

I have to automate the functional scenarios but don't know how to do it or what tools to use.

I have googled from my side and have found that postman currently does not have support for websocket.

I also come across somecode examples but it is not working as the examples were just showing how to send a text to or recieve text from websocket.

And my application requires different type of parameters and value and the examples which I came across shows just to send text and receive text from websocket.

So if you know how to do this, then please help me.

Answer 1

I was able to send the basic input as per my requirement using Karate tool.

Below is the code I modified as per my requirement from the example provided in the documentation, I have used Karate archtype to create this maven project and updated the karate-config.js as per the latest documentation:

1. Feature File Code

@ignore Feature: wspoctest

Scenario: send first webscoket request Given def demoBaseUrl = 'wss://myURL' And def socket = karate.webSocket(demoBaseUrl, null) And def txt = '{"attr1":"value1","attr2":"value2"}'
When socket.send(txt) And def result = socket.listen(5000) Then print(result)

2. Java Code

package wspoc;

import org.junit.BeforeClass;
import org.junit.runner.RunWith;

import com.intuit.karate.KarateOptions;
import com.intuit.karate.junit4.Karate;

@RunWith(Karate.class)

@KarateOptions(features = "classpath:wspoc/wspoc.feature")
public class WSPOCRunner
{

  @BeforeClass
  public static void beforeClass()
  { // skip 'callSingle' in karate-config.js 
      System.setProperty("karate.env", "mock");
  }
}

Now since my basic scenario is working fine, I am planning to modify and update this into the solution which I want.
