How do I simulate a login with RSpec?

Question

I have been playing with Rails for a couple of years now and have produced a couple of passable apps that are in production. I\'ve always avoided doing any testing though an

Add helper file in spec/support/controller_helpers.rb and copy content below

module ControllerHelpers
    def sign_in(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

Now add following lines in spec/rails_helper.rb or spec/spec_helper.rb file

require 'support/controller_helpers'

RSpec.configure do |config|

    config.include Devise::TestHelpers, :type => :controller
    config.include ControllerHelpers, :type => :controller

  end

Now in your controller spec file.

describe  "GET #index" do

    before :each do        
        @user=create(:user)
        sign_in @user
    end
      ...
end
