Rspec测试应该通过但是失败

Question

我从迈克尔哈特尔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

并且观点:

<% 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:

....

Finished in 1.91 seconds
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 | 示例应用程序,这是正确的!

确保你在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
