bundle exec rspec spec / requests / static_pages_spec.rb

Question

在跟随Michael Hartl的RonR教程时，我正试图让我的主页通过我的书面测试。不幸的是，我无法弄清楚为什么我失败了？任何帮助将不胜感激..

规格/请求/ static_pages_spec.rb

require spec helper
require 'minitest/autorun'

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

应用程序/视图/ static_pages / home.html.erb

<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>

所以我跑..

$bundle exec rspec spec/requests/static_pages_spec.rb

结果是......
