vue.js - @Vue/test-utilsshallowMount 为 vuetify 组件输出 "[Vue warn]: Unknown custom element"

Question

我在 Vue 中的单元测试不仅针对 <v-col> 输出以下警告但是对于每个 vuetify 组件:

[Vue warn]: Unknown custom element: < v-col> - did you register the component correctly? For recursive components, make sure to provide the "name" option.

我创建了一个 localVue并添加 Vuetify ，但这似乎不起作用。这是我的测试用例:

import { shallowMount, createLocalVue } from '@vue/test-utils'
import expect from 'expect'
import ProjetoShow from '../../views/Projeto/ProjetoShow.vue'
import Vuetify from 'vuetify'

describe('ProjetoShow component', () => {
    let wrapper
    let localVue
    beforeEach(() => {
        localVue = createLocalVue()
        localVue.use(Vuetify)
    })

    it('renders correctly', ()=> {
        let vuetify = new Vuetify()
        wrapper = shallowMount(ProjetoShow, {localVue, vuetify})
        expect(wrapper.find('h2').text()).toContain('PROJETO')
    })

})

    "@vue/test-utils": "^1.0.0-beta.31",

在 Unit Testing 上的 Vuetify 文档中，他们声明 let vuetify在 describe块，然后在 beforeEach ，将该变​​量分配给 new Vuetify()
我没有看到您在测试代码的任何地方实际初始化 Vuetify，所以也许这就是这里所需要的。
