RoR 教程 Michael Hartl 5.27

Question

我正在关注 Michael Hartl 的 Ruby on Rails 教程，但我在 third exercise of chapter 5 方面遇到了一些麻烦。我创建了 application_helper_spec.rb，其代码与书中的代码完全相同，utilities.rb 现在只有listing 5.38 中指示的行，但是当我运行测试套件时出现此错误：

C:.../sample_app/spec/helpers/appliaction_helper_spec.rb:1: syntax error, unexpected tIDENTIFIER, expecting $end (SyntaxError)
desc...ApplicationHelper do

文件的第一行是：require 'spec_helper'，当我删除这行时，我没有收到这个错误，但我真的不认为这是正确的解决方案。

这是文件中的代码（与书中的相同）

require 'spec_helper'

  describe ApplicationHelper do

    describe "full_title" do
      it "should include the page title" do
        full_title("foo").should =~ /foo/
      end

      it "should include the base title" do
        full_title("foo").should =~ /^Ruby on Rails Tutorial Sample App/
      end

      it "should not include a bar for the home page" do
        full_title("").should_not =~ /\|/
      end
    end
  end

[编辑] spec_helper：

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'

# Requires supporting ruby files with custom matchers and macros, etc,
# in spec/support/ and its subdirectories.
Dir[Rails.root.join("spec/support/**/*.rb")].each {|f| require f}

RSpec.configure do |config|
  # ## Mock Framework
  #
  # If you prefer to use mocha, flexmock or RR, uncomment the appropriate line:
  #
  # config.mock_with :mocha
  # config.mock_with :flexmock
  # config.mock_with :rr

  # Remove this line if you're not using ActiveRecord or ActiveRecord fixtures
  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  # If you're not using ActiveRecord, or you'd prefer not to run each of your
  # examples within a transaction, remove the following line or assign false
  # instead of true.
  config.use_transactional_fixtures = true

  # If true, the base class of anonymous controllers will be inferred
  # automatically. This will be the default behavior in future versions of
  # rspec-rails.
  config.infer_base_class_for_anonymous_controllers = false

  # Run specs in random order to surface order dependencies. If you find an
  # order dependency and want to debug it, you can fix the order by providing
  # the seed, which is printed after each run.
  #     --seed 1234
  config.order = "random"
end

[编辑] application_helper.rb

module ApplicationHelper

  #Returns the full title on a per-page basis.
  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

你的文件名有错别字：

appliaction_helper_spec.rb => application_helper_spec.rb
