ruby-on-rails - 获取在 Rails 中进行测试的方法

Question

我正在关注 RailsSpace: Building a Social Networking Website with Ruby on Rails by Michael Hartl .运行 rails v2.3.2.

我已经到了介绍测试的第 5 章。下面应该使用 get 方法将各个页面的标题与字符串匹配:

require File.dirname(__FILE__) + '/../test_helper' 
require 'site_controller' 

    # Re-raise errors caught by the controller. 
    class SiteController; def rescue_action(e) raise e end; end 

    class SiteControllerTest < Test::Unit::TestCase 
      def setup 
        @controller = SiteController.new 
        @request     = ActionController::TestRequest.new 
        @response   = ActionController::TestResponse.new 
      end 

      def test_index 
        get :index
        title = assigns(:title) 
        assert_equal "Welcome to RailsSpace!", title 
        assert_response :success 
        assert_template "index" 
        end 

      def test_about 
        get :title
        title = assigns(:title) 
        assert_equal "About RailsSpace", title 
        assert_response :success 
        assert_template "about" 
      end 

      def test_help 
        get :help
        title = assigns(:title) 
        assert_equal "RailsSpace Help", title 
        assert_response :success 
        assert_template "help" 
      end 
    end 

在编译时我得到:

Loaded suite site_controller_test
Started
EEE
Finished in 0.057 seconds.

  1) Error:
test_about(SiteControllerTest):
NoMethodError: undefined method `get' for #<SiteControllerTest:0x4854b30>
    site_controller_test.rb:23:in `test_about'

  2) Error:
test_help(SiteControllerTest):
NoMethodError: undefined method `get' for #<SiteControllerTest:0x4854b1c>
    site_controller_test.rb:31:in `test_help'

  3) Error:
test_index(SiteControllerTest):
NoMethodError: undefined method `get' for #<SiteControllerTest:0x485470c>
    site_controller_test.rb:15:in `test_index'

3 tests, 0 assertions, 0 failures, 3 errors

其他人有过this issue唯一建议的解决方案就是重新安装。我对此不感兴趣。由于这是一本较旧的书，因此这可能只是 Rails 版本之间的破损。对于 rails v2.3.2，这相当于什么？

Answer 1

替换所有以下代码

# Re-raise errors caught by the controller. 
class SiteController; def rescue_action(e) raise e end; end 

class SiteControllerTest < Test::Unit::TestCase 
  def setup 
    @controller = SiteController.new 
    @request     = ActionController::TestRequest.new 
    @response   = ActionController::TestResponse.new 
  end

与

class SiteControllerTest < ActionController::TestCase

您使用的代码是指 Rails 2.0/2.1。
