RSpec 控制器 ajax 请求测试

Question

我正在测试我的控制器，但请求是通过ajax发出的。我不知道我该如何处理这个问题。我正在尝试像HTTP请求一样的方式，但我在HTTP请求之前使用XHR。但是当我运行测试时，我看到了这个问题，

1) RwsController Update widget score takes widget rate information
     Failure/Error: mock_widget.should_receive(:update_attributes).with({'these' => 'params'})
       (Mock "Widget_1003").update_attributes({"these"=>"params"})
           expected: 1 time
           received: 0 times
     # ./spec/controllers/rws_controller_spec.rb:28:in `block (3 levels) in <top (required)>'

我有一个控制器，所有 ajax 请求都在这里记录数据库，

class RwsController < ApplicationController
  layout 'widget'
  skip_before_filter :verify_authenticity_token, :only => [:edit, :update, :show, :getUserInfo]
  respond_to :js, :json, :html
  #cookie check and show exact view
  def show
    @widget = Widget.find_by_uuid(params[:uuid])
    if cookies["last_widget_id"] == @widget.uuid
      render :action => "generate"
    end
    @widget = Widget.find_by_uuid(params[:uuid])
  end
  def edit
    @widget = Widget.find_by_uuid(params[:uuid])
  end
  #after rating the rates and other details record on DB
  def update
    @widget = Widget.find_by_uuid(params[:uuid])
    #logger.info("score-in:  " + params[:score])
    @widget.score = params[:score].to_i
    @widget.total_score = params[:total_score].to_i
    @widget.click_number = params[:click_number].to_i
    @widget.average = params[:average].to_i
    #set cookie
    cookies[:last_widget_id] = {:value => @widget.uuid, :expires => 1.year.from_now}
    @widget.save!
    render :text => 'ok'
    logger.info("score-out:  " + @widget.score.to_s)
    logger.info("cookie-id:  " +  cookies[:last_widget_id])
  end
  #iframe creates and calls .js.erb file
  def generate
    @widget = Widget.find_by_uuid(params[:uuid])
    #@widget_id = @widget.id
    respond_to do |format|
      format.js {}
    end
  end
  #recording the visitor who visit the page
  def getUserInfo
    data = params[:mainURL]
    data1 = params[:mainBrowserAgent]
    data2 = params[:mainReferer]
    data3 = params[:mainDisplayInfo]
    data4 = params[:currentWidgetId]
    @widgetTraffic = WidgetTraffic.new(params[:widget_traffic])
    @widgetTraffic.widget_id = @widget_id
    @widgetTraffic.main_url = data
    @widgetTraffic.main_browser = data1
    @widgetTraffic.main_referer = data2
    @widgetTraffic.main_display = data3
    @widgetTraffic.widget_id = data4

    @widgetTraffic.save!
    render :text => 'ok'
  end
end

所有场景都是用户访问侧面并单击链接，其中包含一些信息，例如分数和其他信息，ajax 将数据发送到控制器以保存它，如您在控制器中看到的那样。

但是我解决不了吗？我该怎么做？

更新方法更新@widget对象而不使用update_attributes：

 def update
    @widget = Widget.find_by_uuid(params[:uuid])
    #logger.info("score-in:  " + params[:score])
    @widget.score = params[:score].to_i
    @widget.total_score = params[:total_score].to_i
    @widget.click_number = params[:click_number].to_i
    @widget.average = params[:average].to_i
    #set cookie
    cookies[:last_widget_id] = {:value => @widget.uuid, :expires => 1.year.from_now}
    @widget.save!

但是，您的更新测试期望您将调用 @widget.update_attributes（params）

1) RwsController Update widget score takes widget rate information
     Failure/Error: mock_widget.should_receive(:update_attributes).with({'these' => 'params'})
       (Mock "Widget_1003").update_attributes({"these"=>"params"})
           expected: 1 time
           received: 0 times        

我认为最有可能的是，原始更新方法确实调用了update_attributes，然后修改了该代码。这就是为什么测试现在失败了。
