Make it easy to write WebSocket tests with MockWebServer

I noticed there are some very useful classes to allow testing web sockets code with MockWebServer in okhttp3.internal.ws.*, such as WebSocketRecorder.

It would be nice if these were public (along with anything else needed) so that OkHttp users can easily test their web sockets code with MockWebServer.

For our own needs we have created a small wrapper around MockWebServer: https://github.com/fabric8io/mockwebserver. This wrapper actually provides a DSL and it does make it easy to work with websockets:

For example:

DefaultMockServer server = new DefaultMockServer();
server.expect().get().withPath("/api/v1/users/shell")
        .andUpgradeToWebSocket()
        .open()
             .waitFor(1000).andEmit("#")
            .expect("create root").andEmit("CREATED").once()
            .expect("delete root").andEmit("DELETED").once()
        .done()
        .once();

server.start();

Anyone has working example for WebSocket testing with mockwebserver?
