Rails 教程第 9.3 章失败的测试

Question

我查看了通过问题，但找不到可以解决我的问题的问题。我得到了这些失败的测试。我什至通过浏览器访问了用户索引页面，并看到了登录标题。

Failures:

1) authorization for non-signed-in users in the Users controller visiting the edit page 
 Failure/Error: it { should have_selector('title', text: 'Sign in') }
   expected css "title" with text "Sign in" to return something
 # ./spec/requests/authentication_pages_spec.rb:75:in `block (5 levels) in <top (required)>'

2) authorization for non-signed-in users in the Users controller visiting the user index 
 Failure/Error: it { should have_selector('title', text: 'Sign in') }
   expected css "title" with text "Sign in" to return something
 # ./spec/requests/authentication_pages_spec.rb:85:in `block (5 levels) in <top (required)>'

您的 Authentication_pages_spec.rb 中缺少以下代码：

describe "authorization" do

  subject { page } # This line.

  describe "for non-signed-in users" do
    let(:user) { FactoryGirl.create(:user) }
    .
    .
    .

请参阅http://ruby.railstutorial.org/chapters/filling-in-the-layout#sec-pretty_rspec。

或者，替换

it { should have_selector('title', text: 'Sign in') }

与

page.should have_selector('title', text: 'Sign in')
