Mock websocket server for unit tests

[JulienChampagnol]

Describe the feature

The same way registerEndpoint mocks a server endpoint,
is it possible to create an util that mocks a websocket server?

Additional information

• Would you be willing to help implement this feature?
• Could this feature be implemented as a module?

Final checks

• Read the contribution guide.
• Check existing discussions and issues.

Are you wanting to test Nuxt HMR or are you doing something else with websockets?

[JulienChampagnol]

The goal is to test to mock external features inside of tests

[danielroe]

So this doesn't really seem like a nuxt/test-utils feature request so much as general testing advice, right? You can of course create a websocket server in a test. But I think I (or anyone else) might need some more info on your app, what you are trying and what isn't working for you.
