我有一个请求规范甚至失败，甚至认为它应该通过。规范要查找的所有内容都显示在应用的源（HTML）中。据我所知，这些测试应该通过。我将按顺序列出：
以下是规范代码：
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

答案 0 :(得分：2)
对于新程序员来说，这是一个非常微妙的错误。我正在使用vim编辑器，由于某种原因，4个空格正在扩展到选项卡。布局文件中隐藏的制表符会导致规范失败。
