方法 1：

import {shallowMount} from "@vue/test-utils"

let wrapper = null
const makeWrapper = ()=>{
  wrapper = shallowMount( unittest, {stubs: ['element']})
}

import ElementUI from 'element-ui'

const localVue = createLocalVue()
localVue.use(ElementUI)

let wrapper = null
const makeWrapper = ()=>{
  wrapper = shallowMount( unittest, {localVue}, {})
}
