}`

you don't how expected incoming messages related other actions, beware don't buffer unmatched incoming messages. if messages arrives before set check, it's lost.

if have feedback websocket load test usage, please share , discuss on our mailing list. there's ongoing effort redesign websocket support gatling 3.
