本文介绍了如何使用mock上传文件并在Rails中创建Survey实例的过程。通过定义一个mock_uploader方法来模拟文件上传，然后将模拟文件应用于Survey实例的上传文件字段。最后，验证Survey实例是否成功创建。

1. mock上传文件的代码

 def mock_uploader(file, type = 'image/jpg')
          filename = "%s/%s" % [ File.dirname(__FILE__), file ]
          uploader = ActionController::UploadedStringIO.new
          uploader.original_path = filename
          uploader.content_type = type
          def uploader.read
            File.read(original_path)
          end
          def uploader.size
            File.stat(original_path).size
          end
          uploader
        end

ActionController::UploadedStringIO.new 会生成一个模拟的文件对象
2. 初始化@file

  @file = mock_uploader('1.jpg')

3. 测试方法

 it "should upload the file" do
          #    file = get_file
          tmp = Survey.new(
            :title => "test for upload file",
            :description => "this is for file",
            :upload_file => @file
          )
          tmp.save
          tmp.should_not nil
        end

4. 查看test.log运行结果

 Survey Create (0.3ms)   INSERT INTO `survey` (`title`, `icon_url`, `create_time`, `description`) VALUES('test for upload file', '2010_05_28_14_35_28_1.jpg', '2010-05-28 06:35:28', 'this is for file')
