在spec内时从.getAttribute返回值

async getSingleIdFromDrawerUsing(test1, test2) {
    await browser.wait(async () => {
      return await element(by.xpath('//h3[.="' + test1 + '"]/..' +
        '//something//div[@attr1"' + test2 + '"]')).getAttribute('attr2')
        .then(async (value) => {
          const item = value;
          console.log(item);
          return await item;
      });
    });
  }

从console.log中可以看出,这个函数工作得非常好,但是当我在调用它的spec文件中时,我没有定义它。

以下是我的规范和我正在做的工作:

it('should click into widget from drawer and verify URL has correct Id', async () => {
    const actualReportId = await pagePbject.getSingleIdFromDrawerUsing('test1', 'test2');
    console.log(actualReportId);
    await pagePbject.clickIntoIdFromDrawer('test1', 'test2');
    expect(await browser.getCurrentUrl()).toBe(pagePbject.routeUrl + actualReportId);
});

spits out correct Id from console.log inside the pageObject class
undefined (this is from the spec)
    × should click into test1 test2 widget from the drawer
      - Expected 'http://localhost:49158/url/id' to be 'http://localhost:49158/url/undefined'.

我一定是做错了什么,但我想不出来
