How to do integration testing with RSpec and Devise/CanCan?

Question

If I have a Devise model User, of which only those users with role :admin are allowed to view a certain url, how can I write an RSpec integration test to check that the stat

Answer 1

As of mid 2017, we have one more, in my opinion better opprotunity to integrate devise in our Rspecs. We are able to utilize stub authentization with helper method sign in defined as described below:

module ControllerHelpers
    def sign_in(user = double('user'))
      if user.nil?
        allow(request.env['warden']).to receive(:authenticate!).and_throw(:warden, {:scope => :user})
        allow(controller).to receive(:current_user).and_return(nil)
      else
        allow(request.env['warden']).to receive(:authenticate!).and_return(user)
        allow(controller).to receive(:current_user).and_return(user)
      end
    end
  end

You should also append in spec_helper.rb or rails_helper.rb reference to newly created file:

require 'support/controller_helpers'
  ...
  RSpec.configure do |config|
    ...
    config.include Devise::TestHelpers, :type => :controller
    config.include ControllerHelpers, :type => :controller
    ...
  end

Then in method just place at the beginning of the method body sign_in for context for authenticated user and you are all set. Up to date details can be found in devise docs here
