user_pages_spec.rb 的源程序如下：

 1 require 'spec_helper'
 2 
 3 describe "User pages" do
 4 
 5     subject { page }
 6 
 7     describe "profile page" do
 8         let(:user) { FactoryGirl.create(:user) }
 9         before { visit user_path(user) }
10 
11         it { should have_content(user.name) }
12         it { should have_title(user.name) }
13     end
14 
15     describe "signup page" do
16         before { visit signup_path }
17 
18         it { should have_content('Sign up') }
19         it { should have_title(full_title('Sign up')) }
20     end
21 end

错误如下：
