我有一个失败的请求规范，即使它应该通过。规范正在寻找的所有内容都出现在应用程序的源代码 ( HTML ) 中。据我所知，这些测试应该通过了。我将按顺序列出：

  • 考试
  • 测试中使用的 helper 辅助方法 full_title
  • haml中的相关视图模板
  • 主页或根路由的 HTML 输出
  • Rspec 失败
  • 宝石文件
  • 布局文件

这是规范代码：

require 'spec_helper'

describe "Static pages" do

  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

这是辅助方法full_title：

module ApplicationHelper
  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

主页视图或 /home 路由：

.center.hero-unit
  %h1
    Welcome to the Sample App 
  %h2
    This is the home page for the 
    %a{ href: "http://railstutorial.org"}Ruby on Rails Tutorial sample app

= link_to image_tag("rails.png", alt: "Rails"), 'http://rubyonrails.org'

This is a very subtle error for a new programmer to debug. I'm using the vim editor and for some reason 4 spaces was expanding to a tab. A hidden tab character in the layouts file was causing the specs to fail.
