Question

我从michael hartl书中得到了这个测试：

require 'spec_helper'
  describe "Static pages" do
    let(:base_title) { "Ruby on Rails Tutorial Sample App" }

    describe "Home page" do
      it "should have the h1 'Sample App'" do
        visit '/static_pages/home'
        page.should have_selector('h1', :text => 'Sample App')
      end

      it "should have the title 'Home'" do
        visit '/static_pages/home'
        page.should have_selector('title', :text => "#{base_title} | Home")
      end
  end
end

观点：

<% provide(:title, 'Home') %>
<h1>Sample App</h1>
<p>
  This is the home page for the
  <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a>
  sample application.
</p>

当我运行测试时，它说：

....

4 examples, 0 failures

Randomized with seed 42247

.F...

Failures:

  1) Static pages Home page should have the title 'Home'
     Failure/Error: page.should have_selector('title', :text => "#{base_title} | Home")
       expected #has_selector?("title", {:text=>"Ruby on Rails Tutorial Sample App | Home"}) to return true, got false
     # ./spec/requests/static_pages_spec.rb:16:in `block (3 levels) in <top (required)>'

Finished in 1.91 seconds
5 examples, 1 failure

Failed examples:

rspec ./spec/requests/static_pages_spec.rb:14 # Static pages Home page should have the title 'Home'

Randomized with seed 17491

但它应该通过，因为当我在浏览器中查看页面时，标题是：Ruby on Rails Tutorial Sample App | Sample App，这是正确的！

Answer 1

确保您在Gemfile中使用capybara 1.1.2。从2.0 capybara开始不适用于标题测试（https://github.com/jnicklas/capybara/issues/844）

...
group :test do
  gem 'capybara', '1.1.2'
end

Answer 2

目前，你应该做@dimuch建议的事情，并确保你指定Michael Hartl在教程（1.1.2）中使用的相同Capybara版本。

如果您希望将来升级到Capybara 2.0并保留对标题的测试，请查看this StackOverflow answer以获取创建RSpec匹配器的指南，该指南将执行您期望的操作。

Answer 3

使用capubara 2.0你应该使用

page.should have_title("The title")

但是，如果你不添加

，那就完成了工作

<style type="text/css">head, head title { display: block }</style>

到你的application.html

page.title # => "The title"
page.has_title?("The title") # => true
page.should have_title("The title")

Answer 4

我一直在使用以下内容，他们一直在发布绿色版。我删除了have_selector并使用了have_title。

it { should have_title( full_title('Sign up') ) }

- 和 -

it { should have_title(user.name) }

这是与capybara 2.2.0。

Rspec测试应该通过但是失败
