我正在尝试使用 Mocha + Chai 对包含来自 HereMaps 的 Map 的 VueJS 组件进行单元测试。我按照 VueJS 文档中的官方教程进行操作，进展顺利。
但是，当我想对我的Map.vue组件（包含 HereMap）进行单元测试时，该组件似乎没有正确安装，并且无法克服终端错误。我认为这可能是 HereMap 需要的脚本的问题，但我不确定。
我的单元测试 mapTest.spec.ts如下：
import { shallowMount } from '@vue/test-utils'
import Map from '@/components/Map.vue'
import { expect } from 'chai'
describe('Map', () => {
const wrapper = shallowMount(Map);
it('mounts', () => {
wrapper.setProps({latitude: 0, longitude: 0});
expect(true).equal(true);
})
})
当我评论该行时const wrapper = shallowMount(Map)，错误消失并且测试运行顺利。
有谁知道如何正确地对 HereMap 进行单元测试？
非常感谢您的帮助。
我从 Mocha 得到的错误如下：
