rspec_feature_specs_with_pubsub

After adding pubsub (using Pubnub.com) to our application, our headless specs were straight up breaking. Solved by creating a mock that we can trigger within the specs

Coffeescript required by application.js manifest:

    class PubsubMock
      subscribe: (obj) ->
        @channels ||= {}
        @channels[obj.channel] ||= []
        @channels[obj.channel].push(obj.message)
    
      publish: (channel, message) ->
        for callback in @channels[channel]
          callback(message)

    window.pubsub_listener ||= new PubsubMock()


spec/support/pubsub_mock.rb

    module PubsubMock
      def pubsub_publish(channel, message)
        script = "window.pubsub_listener.publish('#{channel}', '#{message.to_json}')"
        page.execute_script(script)
      end
    end


In a feature spec:

    pubsub_publish('some channel', pubsub_address: user.pubsub_address, event: 'some event')
