ruby on rails - rspec, devise, selenium - login in request spec -

i tried follow these steps https://github.com/plataformatec/devise/wiki/how-to:-test-with-capybara don't pass login page. correct me , show i'm doing wrong? rspec

require 'spec_helper'  include warden::test::helpers    warden.test_mode!    describe "business::contacts"    describe "get /business_contacts", js: true      before(:each)       @account = create :business_account       @account.confirmed_at = time.now       @account.save       login_as(@account, scope: :account, run_callbacks: false)     end  >     "show page restricted access", slow: true >       visit business_contacts_path >       save_and_open_page >     end   

factory:

factory :business_account, class: 'account'   email { faker::internet.email }   username { faker::name.name }   first_name { faker::name.name }   last_name { faker::name.name }   password "foaabar123"   password_confirmation { |u| u.password }   confirmed_at time.now - 1.day   phone_number "2234567890" end 

update 1
i've implemented warden.rb commenting out in factory password_confirmation & changing confirmed_at time.now error:

  1) business::contacts /business_contacts visit restricted webpage      failure/error: unable find matching line backtrace      nomethoderror:        undefined method `env' nil:nilclass 

i created warden.rb in spec/support dir:

rspec.configure |config|   config.include warden::test::helpers, :type => :request  warden.test_mode!   config.after(:each)   warden.test_reset!  end  end 

then, in request spec:

before(:each)   @user = create(:user)   login_as(@user, :scope => :user) end
