Hello,

I am trying to check a binary response. I haven’t found a way online or in doc to do it.

The following just ends up hanging the test:

.exec(ws(“Connect WS”).open("/msg"))

.exec(ws(“Request”)  
.sendText("—")

.check(wsAwait.within(30).until(1))  
)

Is there a ‘checkBinary’ or something similar?
