node.js - Laravel VueJS 测试 TypeError: _vm._ssrEscape 不是函数

问题描述

我一直在拼凑一些不同的教程，试图让 Mocha 测试适用于 Laravel 7 Vue 组件。

我可以成功运行基本测试

expect(0).toBe(0);

但是，一旦我尝试安装一个组件，我就会收到以下错误

TypeError: _vm._ssrEscape is not a function
      at Proxy.render (public/main.js:154:13)

我正在运行节点 12.18.2。

我的测试文件包含

import { mount } from '@vue/test-utils';
import Counter from '../../resources/js/components/Counter';

describe ('Counter', () => {

    it ('defaults to a count of 0', () => {
        const wrapper = mount(Counter);
    });

});

我的组件包含

<template>
    <div>
        <span class="count" v-text="count"></span>
        <button @click="count++"></button>
    </div>
</template>

<script>
    export default {
        name: "Counter",
        data () {
            return {
                count: 0
            };
        }
    }
</script>

测试命令是

mochapack --webpack-config node_modules/laravel-mix/setup/webpack.config.js --require tests/Vue/setup.js tests/Vue/**/*.spec.js

setup.js 文件包含

require('jsdom-global')()
global.expect = require('expect');

谢谢你的帮助

解决方案

我现在有这个工作。

使用部分https://dev.to/tuandm/how-to-test-vue-components-with-laravel-mix-and-mocha-3kgc/

我没有安装 mcocha-webpack 然后卸载，而是直接安装 mochapack

npm install --save-dev webpack vue-template-compiler @vue/test-utils mocha mochapack jsdom jsdom-global expect
