In one terminal, run websocket server:
wscat --listen 9000
In another, run a client, connecting through gateway:
wscat --connect ws://localhost:8080/echo
type away in either server and client, messages will be passed appropriately.
Make sure redis is running on localhost:6379 (using brew or apt or docker).
Then run DemogatewayApplicationTests. It should pass which means one of the calls received a 429 TO_MANY_REQUESTS HTTP status.
