【问题描述】：

我目前正在做 Michael Hartl 的 Ruby on Rails 教程，现在我在第 3 章。H 最后，在使用布局、提供和产量之后，测试应该是成功的，但是，我得到了每次失败 3 次。

我把这个放进去测试一下：

bundle exec rspec spec/requests/static_pages_spec.rb

我得到了这个：

'Failures:

1) StaticPages About page should have the title 'About Us'
 Failure/Error: expect(page).to have_title("Ruby on Rails Tutorial Sample App | About  Us")
   expected #has_title?("Ruby on Rails Tutorial Sample App | About Us") to return true, got false
 # ./spec/requests/static_pages_spec.rb:33:in `block (3 levels) in <top (required)>'

2) StaticPages Help page should have the title 'Help'
 Failure/Error: expect(page).to have_title("Ruby on Rails Tutorial Sample App | Help")
   expected #has_title?("Ruby on Rails Tutorial Sample App | Help") to return true, got false
 # ./spec/requests/static_pages_spec.rb:22:in `block (3 levels) in <top (required)>'

3) StaticPages Home page should have the title 'Home'
 Failure/Error: expect(page).to have_title("Ruby on Rails Tutorial Sample App | Home")
   expected #has_title?("Ruby on Rails Tutorial Sample App | Home") to return true, got false
 # ./spec/requests/static_pages_spec.rb:11:in `block (3 levels) in <top (required)>'

我根本无法找出问题所在。

这是我的布局：

<!DOCTYPE html>
<html>
<head>
  <title>Ruby on Rails Sample App | <%= yield(:title) %></title>
  <%= stylesheet_link_tag    "application", media: "all", "data-turbolinks-track" => true %>
  <%= javascript_include_tag "application", "data-turbolinks-track" => true %>
  <%= csrf_meta_tags %>
</head>
<body>

<%= yield %>

</body>
</html>

这里是我的家：

<% provide(:title, 'Home') %>
<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>

这是我的帮助：

<% provide(:title, 'Help') %>
<h1>Help</h1>
<p>
  Get help on the Ruby on Rails Tutorial at the <a href="http://railstutorial.org/help">Rails Tutorial help page</a>.
  To get help on this sample app, see the <a href="http://railstutorial.org/book">Rails Tutorial book</a>
</p>

这是我的简介：

<% provide(:title, 'About Us') %>
<h1>About Us</h1>
<p>
  The <a href="http://railstutorial.org/">Ruby on Rails Tutorial</a> is a project to make a book and screencasts to teach web development with <a href="http://rubyonrails.org/">Ruby on Rails</a>. This is the sample application for the tutorial.
</p>

如果需要，还有我的 gemfile：

source 'https://rubygems.org'
ruby '1.9.3'
#ruby-gemset=railstutorial_rails_4_0

# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.8'

# Use sqlite3 as the database for Active Record
group :development do
  gem 'sqlite3', '1.3.8'
  gem 'rspec-rails', '2.13.1'
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
  gem 'capybara', '2.1.0'
end

group :production do
  gem 'pg', '0.15.1'
  gem 'rails_12factor', '0.0.2'
end

# Use SCSS for stylesheets
gem 'sass-rails', '4.0.1'

# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '2.1.1'

# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '4.0.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby

# Use jquery as the JavaScript library
gem 'jquery-rails', '3.0.4'

# Turbolinks makes following links in your web application faster. Read more:   https://github.com/rails/turbolinks
gem 'turbolinks', '1.1.1'

# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '1.0.2'

group :doc do
  # bundle exec rake doc:rails generates the API under doc/api.
  gem 'sdoc', '0.3.20',  require: false
end

# Use ActiveModel has_secure_password
# gem 'bcrypt', '~> 3.1.7'

# Use unicorn as the app server
# gem 'unicorn'

# Use Capistrano for deployment
# gem 'capistrano', group: :development

# Use debugger
# gem 'debugger', group: [:development, :test]

希望有人可以帮助我，因为我已经用尽了所有可能出错的想法。也许我错过了一些东西。感谢任何可以回答的人。

标签： ruby-on-rails ruby rspec railstutorial.org

【解决方案1】：

改变

<title>Ruby on Rails Sample App | <%= yield(:title) %></title>

到

<title>Ruby on Rails Tutorial Sample App | <%= yield(:title) %></title>

因为这是您使用 rspec 测试的内容。
