Question

我正在关注Rails 3的Ruby on Rails教程，位于此处：

http://ruby.railstutorial.org

我在本教程的这一部分：

http://ruby.railstutorial.org/chapters/filling-in-the-layout#sec:integration_tests

此时我的所有网页都按预期呈现;例如，我可以点击http://localhost:3000/about并查看示例应用程序的about页面，其中包含预期的标题（“Ruby on Rails Tutorial Sample App | About”）。然而，本节的集成测试仍然失败。

这是我的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 '/about'
    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

当我使用rspec spec/或autotest运行测试时，我会遇到以下测试失败：

    ........FFFF

    Failed examples:

    rspec ./spec/requests/layout_links_spec.rb:20 # LayoutLinks should have a Help page at '/help'

...请注意，测试失败中显示的响应似乎表明我正在获得模拟/存根响应。 我认为这是我的问题，但我不知道为什么会这样。

Answer 1

我明白了。我自己打了上面的测试。当我直接从教程中重新复制/粘贴测试时，他们开始传递。我很神秘，因为一切看起来都一致。但在运行diff之后，我意识到每次测试都输入了：

response should

...但我应该打字：

# Note the "."
response.should

对每个测试进行校正后，它们都按预期通过。

Answer 2

我遇到了完全相同的错误，但原因是忘记在测试中包含render_views行：

require 'spec_helper'

describe PagesController do

    render_views

    describe "GET 'home'" do
        it "should be successful" do
            get 'home'
            response.should be_success
        end
    end
