测试标题不适用于 rspec/capybara
我正在 Rails 3.0.10 上构建我的第一个 Web 应用程序，并尝试在 Pages_Controller_Spec 中纠正我的标题测试，正如我从 ruby on Rails 教程书中学到的那样，但是即使标题在浏览器中正确，测试也会失败。我已经安装了 Capybara，但尚未使用它 - 这是否有潜在的干扰？
您现在会发现它非常基础，但我想从头开始使用可靠的测试套件。任何帮助将不胜感激！
这是我的规范：（简单的“应该成功通过”）
require 'spec_helper'
describe PagesController do
render_views
describe "GET 'home'" do
it "should be successful" do
get 'home'
response.should be_success
end
it "should have the right title" do
get 'home'
response.should have_selector("title",
:content => "Home")
end
end
describe "GET 'contact'" do
it "should be successful" do
get 'contact'
response.should be_success
end
it "should have the right title" do
get 'contact'
response.should have_selector("title", :content => "Contact")
end
end
end
我在应用程序布局中渲染标题，如下所示：
<!DOCTYPE html>
<html>
<head>
<title><%= @title %></title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
</body>
</html>
这是我设置实例变量的方式：
<% @title = "Home" %>
<h1>Pages#home</h1>
<p>Find me in app/views/pages/home.html.erb</p>
编辑：这是测试输出

编辑2：添加内容放置响应体
Running: spec/controllers/pages_controller_spec.rb

I'm building my first webapp on Rails 3.0.10 and trying to right my title tests in my Pages_Controller_Spec as I learned from the ruby on rails tutorial book, however even though the titles are correct in the browser, the tests are failing. I have installed Capybara, but haven't used it yet - is that potentially interfering?
You'll see it's very basic right now, but I want to start from the ground up with a solid testing suite. Any help would be much appreciated!
Here is my spec: (The simple "should be_success pass fine)
require 'spec_helper'
describe PagesController do
render_views
describe "GET 'home'" do
it "should be successful" do
get 'home'
response.should be_success
end
it "should have the right title" do
get 'home'
response.should have_selector("title",
:content => "Home")
end
end
describe "GET 'contact'" do
it "should be successful" do
get 'contact'
response.should be_success
end
it "should have the right title" do
get 'contact'
response.should have_selector("title", :content => "Contact")
end
end
end
I'm rendering the title in the application layout like this:
<!DOCTYPE html>
<html>
<head>
<title><%= @title %></title>
<%= stylesheet_link_tag :all %>
<%= javascript_include_tag :defaults %>
<%= csrf_meta_tag %>
</head>
<body>
<%= yield %>
</body>
</html>
Here is how I'm setting the instance variable:
<% @title = "Home" %>
<h1>Pages#home</h1>
<p>Find me in app/views/pages/home.html.erb</p>
EDIT: Here is the test output
Failures:
1) PagesController GET 'home' should have the right title
Failure/Error: response.should have_selector("title",
expected css "title" to return something
# ./spec/controllers/pages_controller_spec.rb:15:in `block (3 levels) in <top (required)>'
2) PagesController GET 'contact' should have the right title
Failure/Error: response.should have_selector("title", :content => "Contact")
expected css "title" to return something
# ./spec/controllers/pages_controller_spec.rb:29:in `block (3 levels) in <top (required)>'
Finished in 0.14245 seconds

EDIT 2: Adding what puts response.body
Running: spec/controllers/pages_controller_spec.rb
.<!DOCTYPE html>
<html>
<head>
<title>Home</title>
<script src="/javascripts/prototype.js?1315409404" type="text/javascript"></script>

<script src="/javascripts/controls.js?1315409404" type="text/javascript"></script>

<p>Find me in app/views/pages/home.html.erb</p>

结果我没有将 WebRat 作为 gem 安装。我想这是因为我从 Railscast 中获取了测试精华并使用了我在 Hartl 教程中学到的一些测试。
感谢您的帮助！
Turns out I didn't have WebRat installed as a gem. I guess this came from me taking my testing gems from railscast and using some of the tests I learned in the Hartl tutorial.
Thanks for the help!
