自动测试无法测试集成测试

Question

我正在学习 Hartl 的 RoR 教程，现在正在进行集成测试部分。按照指示，我修改了 .autotest ：

require 'autotest/growl'
require 'autotest/fsevent'
require "autotest/restart" 

Autotest.add_hook :initialize do |autotest|
  autotest.add_mapping(/^spec\/requests\/.*_spec\.rb$/) do
    autotest.files_matching(/^spec\/requests\/.*_spec\.rb$/)
  end  
end

我的设置：

Z-Kidds-MacBook-Air:sample_app zkidd$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.2.0]
Z-Kidds-MacBook-Air:sample_app zkidd$ rails -v
Rails 3.1.3

我读出的错误是这样的：

/Users/zkidd/.rvm/rubies/ruby-1.9.2-p290/bin/ruby -rrubygems -S /Users/zkidd/.rvm/gems/ruby-1.9.2-p290/gems/rspec-core-2.6.4/bin/rspec --tty '/Users/zkidd/rails_projects/sample_app/spec/controllers/pages_controller_spec.rb' '/Users/zkidd/rails_projects/sample_app/spec/requests/layout_links_spec.rb'
Exception encountered: #<SyntaxError: /Users/zkidd/rails_projects/sample_app/spec/requests/layout_links_spec.rb:7: syntax error, unexpected ':', expecting ')'
    response.should have_selector('title,' :content => 'Home')
                                            ^
/Users/zkidd/rails_projects/sample_app/spec/requests/layout_links_spec.rb:7: syntax error, unexpected ')', expecting keyword_end>
backtrace: . . . .

我看到错误在 :content 下有一个小胡萝卜，表示自动测试需要“）”而不是冒号。但教程具体说明了我写的内容。这是layout_links_spec.rb

require 'spec_helper'

describe "LayoutLinks" do

  it "should have a Home page at '/'" do
    get '/'
    response.should have_selector('title,' :content => 'Home')
  end

  it "should have a Contact page at '/contact'" do
      get '/contact'
      response.should have_selector('title,' :content => "Contact")
    end

  it "should have an About page at '/about'" do
    get '/contact'
    response.should have_selector('title,' :content => "About")
  end

  it "should have a Help page at '/help'" do
    get '/help'
    response.should have_selector('/title' :content => "Help")
  end

end 

Answer 1

在您发布的代码中，所有类似的行都

response.should have_selector('title,' :content => 'Home')

应该是

response.should have_selector('title', :content => 'Home')

（逗号在字符串之外）。

对于最后一个测试，它也是 'title' 而不是 '/title'
