在阅读第 5 章第 5.3.4 节(漂亮规范)中的 Harlts 教程时。即使按照所有说明操作,我也会收到此错误。
    Static pages Contact page 
     Failure/Error: it { should have_title(full_title('Contact')) }
       expected #has_title?("Ruby on Rails Tutorial Sample App | Contact") to return true, got false

这是spec/support/utilities.rb文件的内容
def full_title(page_title)
  base_title = "Ruby on Rails Tutorial Sample App"
  if page_title.empty?
    base_title
  else
    "#{base_title} | #{page_title}"
  end
end
和static_pages_spec.rb文件的内容
require 'spec_helper'
describe "Static pages" do
  subject { page }
  describe "Home page" do
    before { visit root_path }
    it { should have_content('Sample App') }
    it { should have_title(full_title('home')) }
    it { should_not have_title('| Home') }
  end
  describe "Help page" do
    before { visit help_path }
    it { should have_content('Help') }
    it { should have_title(full_title('Help')) }

  describe "About page" do
    before { visit about_path }
    it { should have_content('About') }
    it { should have_title(full_title('About')) }
  end

    it { should have_content('Contact') }
    it { should have_title(full_title('Contact')) }
