課題３
まず以下のディレクトリを作成

mkdir spec/helpers

次に作成したディレクトリ内で以下のファイルを作成
vim application_helper_spec.rb

application_helper_spec.rb

require 'spec_helper'

describe ApplicationHelper do

  describe "full_title" do
    it "should include the page title" do
      expect(full_title("foo")).to match(/foo/)
    end

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

    it "should not include a bar for the home page" do
      expect(full_title("")).not_to match(/\|/)
    end
  end
end

次にspec/support/utilities.rb
を変更する

utilities.rb

include ApplicationHelper
