Based on the idea of vcr project which record the http interactions and store them as files that can be replayed later and simulate the real communication counterpart (mostly server).
However, this projects aims on the web socket protocol where normally there is only a single HTTP connection and multiple messages or frames being sent over the channel.
it 'should record also the outgoing communication' do
WebSocketVCR.configure do |c|
c.hook_uris = [HOST]
end
WebSocketVCR.record(example, self) do
puts 'we are recording..' if WebSocketVCR.live?
url = "ws://#{HOST}/hawkular/command-gateway/ui/ws"
c = WebSocket::Client::Simple.connect url do |client|
client.on(:message, once: true, &:data)
end
sleep 1 if WebSocketVCR.live?
c.send('something 1')
c.send('something 2')
c.send('something 3')
expect(c).not_to be nil
expect(c.open?).to be true
end
end(source)
after running the code above, you should end up with a file that captured the interactions.
