Javascript Jest:提供的元素或ID无效。（视频JS）

当运行jest覆盖率测试时，我不断得到

元素或提供的ID无效。（videojs）

指向我的JS行：

this.player=videojs（this.videoPlayerID，this.videoJSConfig）。我不确定我在测试中做了什么不正确，或者我没有提供什么

js

试验

import videojs from 'video.js';

class IVSPlayer {
  constructor(data) {
    this.player = {};
    this.registerIVSTech = data.ivsTech;
    this.videoPlayerID = data.id;
    this.videoJSConfig = data.config;
  }

  init() {
    this.registerIVSTech(videojs);
    this.videoJSConfig.techOrder = ['AmazonIVS'];
    this.player = videojs(this.videoPlayerID, this.videoJSConfig);
    return this.player;
  }
}

export default IVSPlayer;

/**
 * @jest-environment jsdom
 */
import ivsPlayer from './../../../ivs-player';
import { VIDEO_PLAYER_ID } from '../../../asset-constants';
import { VIDEO_JS_CONFIG } from './../../../create-player';
import videojs from './../../../node_modules/video.js';


describe('#ivsPlayer', () => {
  it('creates an instance of the IVS player', () => {
    const registerIVSTech = jest.fn();
    const player = new ivsPlayer({ id: VIDEO_PLAYER_ID, config: VIDEO_JS_CONFIG, ivsTech: registerIVSTech });

    expect(player).toBeTruthy();
  });
  it('initializes the IVS player', () => {
    jest.spyOn(ivsPlayer.prototype, 'init');
    const registerIVSTech = jest.fn();
    const player = new ivsPlayer({ id: VIDEO_PLAYER_ID, config: VIDEO_JS_CONFIG, ivsTech: registerIVSTech });

    player.init();

    player.videoJSConfig.techOrder = jest.fn().mockReturnValue(['AmazonIVS']);

    player.registerIVSTech = jest.fn().mockReturnValue(player);


    expect(player.init).toHaveBeenCalledTimes(1);
  });
});
