Я реализую функцию ленивого входа. Моя особенность огурца должна описать это:

    Feature: User log in

        Scenario: Lazy login
            Given I didn't log out the last time I was on the site
            When I go to the homepage
            Then I should automatically be logged in 

И это мои определения шагов:

Given(/^I didn't log out the last time I was on the site$/) do
  user = FactoryGirl.create(:user)
  visit new_user_session_path
  fill_in('user[email]', with: user.email)
  fill_in('user[password]', with: 'test123')
  click_button('Sign in')

  Capybara.reset_sessions!
end

When(/^I go to the homepage$/) do
  visit root_path
end

Then(/^I should automatically be logged in$/) do # "mysite.com",
      :secure => !(Rails.env.test? || Rails.env.development?)
      }
    puts "current_user.remember_token = #{current_user.remember_token}"
    puts 'cookies:'
    puts cookies.signed[:auth_token]
  end
end

конец

Это фильтр до в моем ApplicationController:

def sign_in_through_cookie
  logger.info "logging in by cookie"
  puts "logging in by cookie"
  puts cookies.signed[:auth_token] #
