How do I mock websocket in ember-cli-mirage?

I want to know of anyway using which I can mock a websocket in ember-cli-mirage. Currently ember-cli-mirage does not support this. They may in future I guess. Here's the link to the ticket : https://github.com/samselikoff/ember-cli-mirage/issues/1273 Meanwhile can you suggest anyway to achieve this? Or if you're already mocking a websocket using mirage, can you share how?
