ruby-on-rails - 在 Rails 3.2.12 中从 webrat 迁移到 capybara 后未定义的方法“访问”

Question

我们正在将 rails 集成测试从 webrat 迁移到 capybara。替换response.should为response.body.should。还添加require 'capybara/rails'到 spec_helper.rb。但是有一个错误说undefined method 'visit'。每一个都会visit导致错误。这是导致错误的前 2 段代码：

describe "TestPaths" do
  describe "GET /customerx_test_paths" do
    before(:each) do
      ul = FactoryGirl.build(:user_level, :sys_user_group_id => ug.id)
      u = FactoryGirl.create(:user, :user_levels => [ul], :login => 'thistest', :password => 'password', :password_confirmation => 'password')
      visit 'authentify/'
      fill_in "login", :with => u.login
      fill_in "password", :with => 'password'
      click_button  
    end

    #customer status category
    it "should display customer status category index page" do
      visit customer_status_categories_path
      response.body.should have_selector("title", :content => "Customerx")
    end

...
end

对于下面的 rspec 案例，之前的循环只是登录到系统。水豚代码有什么问题？感谢帮助。
