Question

我已经添加了问题Vue-Test-Utils Unknown custom element: 的解决方案，但该解决方案无效。

当我尝试在单元测试规范中运行shallowMount时遇到问题：

[Vue警告]：未知的自定义元素：-您是否注册组件正确吗？对于递归组件，请确保提供“名称”选项。

这是我的规范：

import { shallowMount, createLocalVue, RouterLinkStub } from '@vue/test-utils';
import VueRouter from 'vue-router';
import Vuetify from 'vuetify';
import expect from 'expect';
import Home from '../../pages/Home.vue';

describe('Home.vue', () => {
    // let wrapper;
    let localVue;
    beforeEach(() => {
        // wrapper = shallowMount(Home);
        localVue = createLocalVue();
        localVue.use(Vuetify)
        localVue.use(VueRouter)
    });

    it('renders the Home page component', () => {
        debugger;
        let wrapper = shallowMount(Home, { localVue, stubs: { RouterLink: RouterLinkStub } });
        expect(wrapper.html()).toContain('<h2>Bem-vindo (a) ao Cadastro Nacional de Informações Espeleológicas - CANIE</h2>');
    });
});

我的Home.vue组件：

<template>
        <v-card class="elevation-7">
            <v-card-title>
                <h2>Bem-vindo (a) ao Cadastro Nacional de Informações Espeleológicas - CANIE</h2>
            </v-card-title>
            <v-container>
                <v-row class="align-center justify-space-around fill-height" my-2>
                        <v-btn :to="{name: 'cavernaRegister'}">CADASTRAR CAVERNA</v-btn>
                        <v-btn to="/caverna">CAVERNAS PENDENTES</v-btn>
                        <v-btn to="/relatorio">RELATÓRIO</v-btn>
                </v-row>
                <v-row class="justify-center" my-2>
                    <v-col cols="4">
                        <v-card>
                            <v-card-title primary-title class="headline">
                                <div>
                                    <h3 class="headline mb-0">Cavernas por Estados</h3>
                                </div>
                            </v-card-title>
                            <v-divider></v-divider>
                            <div id="canvas-holder">
                                <canvas id="chart-area"></canvas>
                            </div>
                        </v-card>
                    </v-col>
                </v-row>
            </v-container>
        </v-card>
</template>

<script>

import colors from 'vuetify/es5/util/colors'
import Chart from 'chart.js'
export default {
    name: 'Home',
    data(){
        return {
          config: { ...
          },
        }
    },
    mounted(){
        let ctx = document.getElementById('chart-area').getContext('2d');
        window.doughnutChart = new Chart(ctx, this.config);
    },
}
</script>

我正在使用@vue/test-utils: "^1.0.0-beta.31"和mocha "^6.1.4"。是否有解决此问题的解决方法？

Answer 1

我在vue测试实用程序documentation中找到了一个如何对router-view和router-link进行存根的示例：

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

shallowMount(Component, {
  stubs: ['router-link', 'router-view']
})

Answer 2

2021 年更新：现在需要将其设置为全局属性

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

shallowMount(Component, {
  global: {
      stubs: ['router-link', 'router-view']
  }
})

@ vue / test-utils未知的自定义元素：<router-view>
