虚拟用户.js试验:w单元测试实用程序和笑话:[vue test utils]:包装器.销毁()只能在Vue实例上调用

 it("should test lifecycle when audio tag is destroyed", () => {
    // jsdom doesn't support any loading or playback media operations. 
    // As a workaround you can add a few stubs in your test setup:
    window.HTMLMediaElement.prototype.removeEventListener = () => { /* do nothing */ };
    // given
    const wrapper = mount(AudioPlayer, {
     // attachToDocument: true,
      propsData: {
        autoPlay: false,
        file: file,
        ended,
        canPlay
      }
    });
    wrapper.vm.loaded = true; // enable buttons
    const player = wrapper.find("#player");
    expect(wrapper.contains('#playPauseBtn')).toBe(true);
    // when
    player.destroy()
    // then
    expect(wrapper.contains('#playPauseBtn')).toBe(false);
  });

但是我得到了一个错误,即使destroy()在文档中使用。。。

[vue测试实用程序]:包装器.销毁()只能在Vue实例上调用

  177 |     expect(wrapper.contains('#playPauseBtn')).toBe(true); // OK
  178 |     // when
> 179 |     player.destroy()

我错在哪里?
