Question

我正在迈克尔·哈特尔（Michael Hartl）做轨道tutorial，我无法在第3章中通过考试。

static_pages.rb文件：

require 'spec_helper'

describe "Static pages" do

  describe "Home page" do

    it "should have the content 'Sample App'" do
      visit '/static_pages/home'
      expect(page).to have_content('Sample App')
    end
  end
end

home.html.erb文件：

<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>

这是测试的结果：

An error occurred in an after hook
  ArgumentError: rack-test requires a rack application, but none was given
  occurred at C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/capybara-2.1.

我目前的Capybara版本是2.1.0，但我尝试将版本更改为1.1.2并捆绑更新，但也没有工作。还尝试了不同的语法进行测试。

page.should have_title("Sample App")
page.should have_selector('h1', :text => 'Sample App')
page.should have_selector('title', text: 'Sample App')

我的系统是Windows 7，我的rails版本是4.0.8，Ruby版本是1.9.3。

尝试搜索“机架测试需要机架应用程序，但没有给出”错误，似乎我需要更改，以便机架不是默认驱动程序。这就是我的配置文件的样子。

# This file is copied to spec/ when you run 'rails generate rspec:install'

require 'capybara/rspec'

RSpec.configure do |config|
  config.include Capybara::DSL
end

无法通过railstutorial.org第3章获得rspec测试
