这是我的 spec.rb 文件...

require 'spec_helper'

describe "StaticPages" 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
  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

我不确定我做错了什么。如果有任何帮助，我将不胜感激。

谢谢!!!

问题出在你的规范文件中——

describe "StaticPages" 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
end

您过早地结束了 rspec 上下文——将最后一个“结束”移动到您的规范的底部，您的测试应该全部通过。

干杯!
