Websockets (and any other connection upgrade) does not support local testing.

[the10thWiz]

What's missing?

As noted in #2836, Websockets cannot be tested with a local client. Ideally, local::Client should expose the ability to perform a connection upgrade, so that rocket_ws can implement proper testing functionality.

Why can't this be implemented outside of Rocket?

Although web socket specific code can and should live outside Rocket, the local client code needs to support the upgrade mechanism to allow the external implementation.

Are there workarounds usable today?
