Typescript Jasmine 测试用例一直失败

Question

我不知道为什么会出现以下测试失败，这表明我正在使用find() 。 我正在寻找一个按钮购买testID ，触发点击，并使用find()来检查我要检查的其他 2 个元素。：

**

[chunk-2]         Expected $.length = 0 to equal 2.
[chunk-2]         Expected $[0] = undefined to equal 'oldClock'.
[chunk-2]         Expected $[1] = undefined to equal true.

**

describe('@emitTime', function () {
  it('emits a time event when clock is clicked', function (this: TestContext) {
    this.wrapper = this.mountComponent(TimeClockComponent, {
      notids: [

        {
          enabled: false,
          name: 'newClock',
        },
      ],
    });

    this.wrapper.find(testID('TimeClockComponent')).trigger('click');
    this.wrapper.find(testID('item-oldClock');
    this.wrapper.find(testID('item-newClock');

    expect(this.wrapper.emitted()!.emitTime![1]).toEqual(['oldClock', true]);

    expect(this.wrapper.emitted()!.emitTime![2]).toEqual(['newClock', true]);

  });
});
