[Rails-core] Unit testing ActionCable

[Roman Snitko]

It seems there currently is no easy (or hard even) way to unit test 
ActionCable channels, which makes me very sad. There is a bit of logic in 
my Channels which would be very nice to cover with tests. Ideally, I'd like 
to have something like this:

it "rejects connection if current_user isn't the owner of the contract" 
do
  channel = create_channel(:contract)
  sign_in @unauthorized_user
  expect(channel.subscribe(params: {contract_id: 1}).to 
reject_connection
end

Is this something even remotely likely to happen? I googled very hard and I 
also checked every ActionCable issue (opened & closed) and couldn't find 
anyone asking this question.
