Protractor 如何使用量角器测试从API获取数据的表

在Angular8项目中，我想用量角器测试一个包含从API获得的数据的表

在我的HTML页面中：

      <tr *ngFor="let pop of popList" class="pops-list">
        <td>{{pop.name}}</td>
        <td class="pop-description">{{pop.description}}</td>
        <td>{{pop.id}}</td>
        <td>{{pop.area}}</td>
        <td>{{pop.timeZone}}</td>
      </tr>

在我的测试中，我尝试：

await element.all(by.repeater('pop in popList')).count().then(count => console.log(count));

count.toEqual（3）给出了错误： 类型“number”上不存在属性“toEqual”

你能帮个忙吗？

所以使用async和Wait可以很好地工作，但不确定这是否是最好的方法， 在我的等级库文件中：

  it('should be populated with list data', async () => {
    await page.navigateToAdministration();
    let popList = await element.all(by.css('table .pops-list'));
    expect(popList.length).toBe(41);
  });

  it('should display correct POP names', async () => {
    await page.navigateToAdministration();
    const popItems = await element.all(by.css('.pops-list')).all(by.css('.pop-name'));
    expect(popItems[0].getText()).toEqual('AMI');
    expect(popItems[1].getText()).toEqual('ANN');
    expect(popItems[2].getText()).toEqual('AUB');
  });

我在html中添加了一些css类以供选择

  it('should be populated with list data', async () => {
    await page.navigateToAdministration();
    let popList = await element.all(by.css('table .pops-list'));
    expect(popList.length).toBe(41);
  });

  it('should display correct POP names', async () => {
    await page.navigateToAdministration();
    const popItems = await element.all(by.css('.pops-list')).all(by.css('.pop-name'));
    expect(popItems[0].getText()).toEqual('AMI');
    expect(popItems[1].getText()).toEqual('ANN');
    expect(popItems[2].getText()).toEqual('AUB');
  });
