typescript - 开玩笑测试 - TypeError：document.createRange 不是函数

Question

我的测试

import VueI18n from 'vue-i18n'
import Vuex from "vuex"
import iView from 'view-design'
import {mount,createLocalVue} from '@vue/test-utils'
// @ts-ignore
import FormAccountName from '@/views/forms/FormAccountName/FormAccountName'
const localVue = createLocalVue()
localVue.use(Vuex)
localVue.use(iView)
localVue.use(VueI18n)
describe('a',()=>{
    test('b',async ()=>{
        const wrapper = mount(FormAccountName,{
            localVue,
            mocks: {
                $t: () => 'this is a label',
                formItems: {
                    name: '<a>'
                }
            },
        })
        expect(wrapper).toMatchSnapshot()
    })
})

错误

快照正常生成，但报错

作为 iView 标签，但我已经对其进行了初始化。所以我不知道出了什么问题。有人可以帮助我吗？

Answer 1

在 pollyfill.js 或 testSetup 中添加以下配置模拟代码

global.document.createRange = () => ({
        setStart: () => {},
        setEnd: () => {},
        commonAncestorContainer: {
            nodeName: 'BODY',
            ownerDocument: document
        },
        createContextualFragment: jest.fn
    });

Answer 2

document.createRange = () => ({
    setStart: () => {},
    setEnd: () => {},
    //@ts-ignore
    commonAncestorContainer: {
      nodeName: "BODY",
      ownerDocument: document,
    },
  })
