Question

我目前正在通过Hartl工作。在第5章中，我将Hartl的代码从5.27（下面）列表添加到我的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 test时，终端返回此错误：

有什么想法吗？

Answer 1

你的spec_helper.rb档案中有这一行吗？

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app / helpers / application_helper.rb文件，看起来像这样吗？

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，我认为你的错误应该消失。

Answer 2

您好我还关注了Michael的Rails 3.2版本教程并得到了相同的错误...尝试使用当前版本的capybara

我将：文字更改为：内容并使其正常工作，所以它看起来像这样：

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

希望它有所帮助，欢呼！

Answer 3

第5章的练习是

“消除了对清单5.26中的full_title测试助手的需求为原始帮助器方法编写测试，如清单所示 5.37。（您必须同时创建spec / helpers目录和application_helper_spec.rb文件。）然后将其包含在测试中代码清单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测试时仍然出错。他们只能在full_title

中定义utilites.rb才能让它通过

Answer 4

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')) }

Answer 5

考虑到这篇文章已有两年了，我猜你已经弄明白了。不过，请尝试添加

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

在spec \ requests \ spec_helper.rb

中
