How to manually create socket errors - node websocket(ws)?

I am using ws for websocket in my node application. I want to simulate the possible errors that the server can get. I don't want to modify the server code, so I am trying to do that from the client side.

When I am emitting an error from the client side, that error was coming to client error handler, not going to the server. How can I send the error to the server(not as a message, as error event), so that I can test the error handlers there?

This is what I tried,

var WebSocket = require('ws')
var server = //url
var myClient = new WebSocket(server);

myClient.on('open', function() {
  setTimeout(function() {
    sendError(myClient);
  }, 5000);
});

myClient.on('error', clientErrorHandler(){
  //client error handler
  //This is being executed when emitting error
})

myClient.on('close', closeS(){
  //to clear some data
})

function sendError(client){
  client.emit('error', new Error('ECONNRESET'));
}

When the error emitted , clientErrorHandler got executed. It is not going to server. But I want this to be handled by server's error handler. How can that be done?
