Ruby on Rails 3 + Rspec + Capybara：检查响应状态

问题描述

我从Webrat迁移到Capybara，现在遇到很多错误。例如在webrat中，我可以在集成测试中使用它：

I migrated from Webrat to Capybara and now i get a lot of errors. For example in webrat i could use that in integration test:

response.should be_success

但是Capybara显示：

But Capybara shows that:

Failure/Error: response.should be_success
     NoMethodError:
       undefined method `success?' for nil:NilClass

有没有提供这种功能的方法？

Is there any method that provides such function?

UPD ：我的规范：

require 'spec_helper'

describe "Admins" do
  before(:each) do
    @admin = FactoryGirl.create(:admin)

    visit '/'
    click_link "Login"
    fill_in "Email",  :with => @admin.email
    fill_in "Password", :with => 'qwerty'
    click_button "Sign in"
  end

  describe "Admin panel" do
    it "should have correct links" do
      click_link "User"
      response.should be_success
    end
  end
end

推荐答案

您正在混合控制器并索取规格。

You're mixing controller and request specs.

在控制器规范中，您检查响应；在请求规范中，您检查页面内容，因为您只能访问html。

In a controller spec you check the response, in a request spec, you check the page content, since you have only access to the html.
