Jest 单元测试 Vue 项目中引入的 mint-ui 报错

import {createLocalVue, mount} from '@vue/test-utils'
import inputCheckData from '@/pages/health/inputCheckData'
import MintUI from 'mint-ui';

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

describe('health/inputCheckData.vue', () => {
  it('check query', () => {
    const $route = {
      query: {
        id: 1
      }
    }
    const wrapper = mount(inputCheckData, {
      localVue,
      mocks: {
        $route
      }
    })
    expect(wrapper.vm.$route.query.id).toBe(1)
    expect(wrapper.vm.$data.type).toBe(1)
  })
})
