@Vue/test-utilsshallowMount 为 vuetify 组件输出“[Vue 警告]：未知的自定义元素”

Question

我在 Vue 中的单元测试不仅<v-col>为每个 vuetify 组件输出以下警告：

[Vue 警告]：未知的自定义元素：<v-col> - 您是否正确注册了组件？对于递归组件，请确保提供“名称”选项。

我创建了一个localVue并添加了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')
    })

})

我的包版本在 package.json

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

我犯了一个错误，将 vuetify 添加到localVue而不是添加Vue。这改变修复了它。根据所使用的版本，这仍然可能输出一些错误。如果出现问题，请更新vuetify和@vue/test-utils到最新版本。mocha

import { shallowMount, createLocalVue } from '@vue/test-utils'
import expect from 'expect'
import ProjetoShow from '../../views/Projeto/ProjetoShow.vue'
import Vuetify from 'vuetify'
import VueRouter from 'vue-router'
import Vue from 'vue'
Vue.use(Vuetify)

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

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

})
