action-cable-testing with Devise

My Ruby on Rails application is working as desired. Things are getting broadcast and received as I want. However, I want to add unit testing to channels using action-cable-testing gem. My user registration is done using Devise. Here is my connection.rb file: 

module ApplicationCable
  class Connection < ActionCable::Connection::Base
    identified_by :current_user

    def connect
      self.current_user = find_verified_user
    end

    private
    def find_verified_user
      if verified_user = env['warden'].user
        verified_user
      else
        reject_unauthorized_connection
      end
    end
  end
end

I have a message_notifications_channel.rb like this: 

class MessageNotificationsChannel < ApplicationCable::Channel
  def subscribed
    # stream_from "some_channel"
    if current_user&.account_id
      stream_from "message_notifications_channel_#{current_user.account_id}"
    end
  end

  def unsubscribed
    # Any cleanup needed when channel is unsubscribed
  end
end

This channel allows a user, when signed in, to stream from message_notifications_channel_accountID where accountID is id of the account to which the user belongs.

My cable.js file is the same as shown in the ruby guide: 

// Action Cable provides the framework to deal with WebSockets in Rails.
// You can generate new channels where WebSocket features live using the `rails generate channel` command.
//
//= require action_cable
//= require_self
//= require_tree ./channels

(function() {
  this.App || (this.App = {});

  App.cable = ActionCable.createConsumer();

}).call(this);

I'm having trouble with the following rspec test: 

require 'rails_helper'

RSpec.describe MessageNotificationsChannel, type: :channel do
  let(:authorized_senders) {['11111']}
  let(:common_user_phone){'17777777777'}
  let(:account) {FactoryGirl.create(:account, authorized_senders: authorized_senders)}
  let(:user){FactoryGirl.create(:user, account: account, admin: true)}
  context 'when user is authenticated' do
    describe '#connect' do
      it 'accepts connection' do
        sign_in user
        subscribe(account_id: user.account_id)
      end
    end
  end
end

The error I got is: Failure/Error: if current_user&.account_id

 NameError:
   undefined local variable or method `current_user' for #<MessageNotificationsChannel:0x000000000721d890>

The location of the error is in my message_notifications_channel.rb file. I put a byebug before self.current_user = find_verified_user in the connect method in connection.rb, the test would not hit that byebug at all. And no surprise, I would get that error later.

When I'm running in development environment that byebug will get hit and things will run normally.

This is my cable.yml:

redis: &redis
  adapter: redis
  url: redis://localhost:6379/1

production: *redis
development: *redis
test:
 *redis

I've looked at https://github.com/palkan/action-cable-testing/issues/26#issuecomment-392481619 That person's code does not really use Devise. It's crucial that all parts of my app uses devise for user authentication. Thanks!

Try to add "stub_connection current_user: users(:some_user_from_fixtures)" to your test. So for your code it would be:

   it 'accepts connection' do
        sign_in user
        stub_connection current_user: user
        subscribe(account_id: user.account_id)
   end

This should work. For more information visit rails official documentation: Testing Action Cable
