Since the version 2.1.0of capybara there are methods on the session to deal with the title. You have
从2.1.0版本的水豚开始，会话中有处理标题的方法。你有
page.title
page.has_title? "my title"
page.has_no_title? "my not found title"
So you can test the title like:
所以你可以像这样测试标题：
expect(page).to have_title "my_title"

This works under Rails 3.1.10, Capybara 2.0.2 and Rspec 2.12, and allows matching partial contents:
这适用于 Rails 3.1.10、Capybara 2.0.2 和 Rspec 2.12，并允许匹配部分内容：
find('title').native.text.should have_content("Status of your account::")
回答by Dylan Markow
You should be able to search for the titleelement to make sure it contains the text you want:
您应该能够搜索该title元素以确保它包含您想要的文本：
page.should have_xpath("//title", :text => "My Title")

I added this to my spec helper:
我将此添加到我的规范助手中：
class Capybara::Session
def must_have_title(title="")
find('title').native.text.must_have_content(title)
end
end
Then I can just use:
然后我可以使用：
it 'should have the right title' do
page.must_have_title('Expected Title')
end

Testing the Title of each page can be done in a much easier way with RSpec.
使用 RSpec 可以更轻松地测试每个页面的标题。
require 'spec_helper'
describe PagesController do
render_views
describe "GET 'home'" do
before(:each) do
get 'home'
@base_title = "Ruby on Rails"
end
it "should have the correct title " do
response.should have_selector("title",
:content => @base_title + " | Home")
end
end
end

In order to test for the title of a page with Rspec and Capybara 2.1 you could use
为了使用 Rspec 和 Capybara 2.1 测试页面的标题，您可以使用
expect(page).to have_title 'Title text'another option is
expect(page).to have_css 'title', text: 'Title text', visible: false
Since Capybara 2.1 the default isCapybara.ignore_hidden_elements = true, and because the title element is invisible you need the optionvisible: falsefor the search to include non visible page elements.
expect(page).to have_title 'Title text'另一种选择是
expect(page).to have_css 'title', text: 'Title text', visible: false
由于 Capybara 2.1 的默认值是Capybara.ignore_hidden_elements = true，并且由于标题元素是不可见的，因此您需要visible: false搜索选项以包含不可见的页面元素。

You just need to set the subjectto pageand then write an expectation for the page's titlemethod:
你只需要设置subjecttopage然后为页面的title方法写一个期望：
subject{ page }
its(:title){ should eq 'welcome to my website!' }
In context:
在上下文中：
require 'spec_helper'
describe 'static welcome pages' do
subject { page }
describe 'visit /welcome' do
before { visit '/welcome' }
its(:title){ should eq 'welcome to my website!'}
end
end
