Question

您好我遇到了这个问题，我正在测试我的助手，它应该设置实例可用，但在测试时，当我使用它分配它总是返回nil

这是我的帮手：

def popup_campaign
    return "" if cookies["hide_popup_campaign"] == "1"
    popup = PopupCampaign.current(current_locale)
    @popup_campaign = popup.exists? && popup.first.active ? popup.first : false
    puts @popup_campaign # just cheking

    render :partial => 'layouts/shared/popup_campaign'
  end

这是测试

it "should return valid instance" do
      popup.save(:validate => false)
      helper.request.cookies["hide_popup_campaign"] = "0"
      helper.stub(:current_locale).and_return("lv")
      helper.popup_campaign
      expect(assigns(:popup_campaign)).to be_present
    end

和控制台日志：

PublicHelper
  popup_campaign
#<PopupCampaign:0x0000010bb64cc8>
    should return valid instance (FAILED - 1)

失败：

 1) PublicHelper popup_campaign should return valid instance
     Failure/Error: expect(assigns(:popup_campaign)).to be_present
       expected present? to return true, got false

有谁能告诉我我做错了什么？谢谢你:)）

我没有找到如何从助手分配实例变量。相反，我重构了代码，根本不使用实例，并测试部分是否渲染！

类似的东西：

def popup_campaign
    return "" if cookies["hide_popup_campaign"] == "1"
    popup = PopupCampaign.current(current_locale)
    campaign = popup.exists? && popup.first.active ? popup.first : false

    render :partial => 'layouts/shared/popup_campaign', locals: {popup: campaign} if campaign
end

测试：

it "should render" do
      popup.save(:validate => false)
      helper.request.cookies["hide_popup_campaign"] = "0"
      helper.stub(:current_locale).and_return("lv")
      expect(helper.popup_campaign).to render_template('layouts/shared/popup_campaign') # or not_to 
    end

rspec分配（）不起作用
