ruby-on-rails - MichaelHartlのRailsチュートリアルから仕様の失敗を要求する

Question

合格するはずなのに失敗しているリクエストスペックがあります。仕様が探しているすべてのコンテンツは、アプリのソース（HTML）に表示されます。これらのテストは、私が知る限り合格しているはずです。順番にリストします。

テスト
テストで使用されるヘルパーヘルパーメソッドfull_title
hamlの関連するビューテンプレート
ホームページまたはルートルートのHTML出力
Rspecの失敗
Gemfile
レイアウトファイル

スペックコードは次のとおりです。

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

ヘルパーメソッドは次のfull_titleとおりです。

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

これは、新しいプログラマがデバッグするための非常に微妙なエラーです。私はvimエディターを使用していますが、何らかの理由で4つのスペースがタブに展開されていました。レイアウトファイル内の非表示のタブ文字が原因で、spec が失敗していました。
