我目前正在通过 Hartl 工作。在第 5 章中，我将清单 5.27（如下）中的 Hartl 代码添加到我的 spec/requests/static_pages_spec.rb

require 'spec_helper'

describe "Static pages" do

subject { page }

describe "Home page" do
before { visit root_path }

it { should have_selector('h1',    text: 'Sample App') }
it { should have_selector('title', text: full_title('')) }
it { should_not have_selector 'title', text: '| Home' }
end

describe "Help page" do
before { visit help_path }

it { should have_selector('h1',    text: 'Help') }
it { should have_selector('title', text: full_title('Help')) }
end

describe "About page" do
before { visit about_path }

it { should have_selector('h1',    text: 'About') }
it { should have_selector('title', text: full_title('About Us')) }
end

describe "Contact page" do
before { visit contact_path }

it { should have_selector('h1',    text: 'Contact') }
it { should have_selector('title', text: full_title('Contact')) }
end
end

当我运行 $ bundle exec rspec spec/requests/static_pages_spec.rb 测试时，终端返回此错误：

有任何想法吗？

您好，我还关注了 Michael 的 Rails 3.2 版本教程并得到了同样的错误......试试你当前版本的水豚

我将:text更改为:content并让它工作，所以它看起来像这样：

it { should have_selector('title', content: full_title('')) }

希望有帮助，加油！

你的 spec_helper.rb 文件中有这一行吗？

Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

你有一个看起来像这样的 spec/support/utilities.rb 文件吗？

include ApplicationHelper

def sign_in(user)
  visit signin_path
  fill_in "Email",    with: user.email
  fill_in "Password", with: user.password
  click_button "Sign in"
  # Sign in when not using Capybara as well.
  cookies[:remember_token] = user.remember_token
end

你有一个看起来像这样的 app/helpers/application_helper.rb 文件吗？

module ApplicationHelper

  # Returns the full title on a per-page basis.
  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
end

如果是这样，我认为您的错误应该消失。

第 5 章的练习内容为

"通过为原始辅助方法编写测试来消除对清单 5.26 中 full_title 测试帮助器的需要，如清单 5.37 所示。（您必须同时创建 spec/helpers 目录和application_helper_spec.rb文件。）然后将其包含到测试中使用清单 5.38 中的代码。”

http://ruby.railstutorial.org/chapters/filling-in-the-layout.html#sec-layout_exercises

这是否意味着我只需要“包含 ApplicationHelper”我的utilites.rb文件，因为spec/helpers/application_helper_spec.rb现在包含

require 'spec_helper'

describe ApplicationHelper do

  describe "full_title" do
    it "should include the page title" do
      full_title("foo").should =~ /foo/
    end

进行此设置后，我在运行 RSpec 测试时仍然遇到错误。他们唯一能让我通过的方法是full_title在utilites.rb

考虑到这篇文章已经有两年了，我想你已经明白了。不过，尝试添加

RSpec.configure do |config|
...
config.include ApplicationHelper
...
end

在 spec\requests\spec_helper.rb 中

当前格式应如下所示，以便您的测试通过：

it { should have_title(full_title('Help')) }

it { should have_title(full_title('About')) }

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