我正在研究 Ruby on Rails 第二版，Hartl。在第 3.3.3 节中，我使用一些嵌入式 Ruby 删除了一些静态文本后，我的测试失败了。测试通过之前没有问题。

rspec

    require 'spec_helper'

    describe "Home pages" do

      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 => "Ruby on Rails Tutorial Sample                 App | Home")
        end  
      end
    end

主页.html.erb

    <% provide (:title, 'Home') %>
    <!DOCTYPE html>
    <html>
       <head>
          <title>Ruby on Rails Tutorial Sample App | <%= yield(:title) %></title>
       </head>
       <body>
          <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>
       </body>
    </html>

我认为您需要在括号之前删除空格

provide (:title, 'Home')

应该

provide(:title, 'Home')
