Question

我有一个非常简单的量角器测试，它可以进入我的网站，登录并获取菜单按钮的文本，该菜单按钮的文本应该以用户名作为按钮的内文。不幸的是，当我调用getText（）时，即使我尝试通过.then函数手动解决承诺，承诺也无法解决（我将默认超时设置为5分钟）。测试代码如下：

describe('workspace-project App', () => {
  let page: AppPage;
  const secretsManagerService: SecretsManagerService = new SecretsManagerService();
  let username: string;
  let password: string;
  let getSecretCallback = async (err: AWSError, data: GetSecretValueResponse) => {
    if(err) {
      throw err;
    }
    data.SecretString;
  }

  beforeEach((done) => {
    page = new AppPage();
    let request: AWS.Request<SecretsManager.Types.GetSecretValueResponse, AWSError> = secretsManagerService.getSecret("/dev/ui/test/username");
    request.send();
    request.promise().then((data) => {
      username = data.SecretString;
      request = secretsManagerService.getSecret("/dev/ui/test/password");
      request.send();
      request.promise().then((data) => {
        password = data.SecretString;
        done();
      })
    })

  });

  it('should login', async () => {
    await page.navigateTo();
    await page.navigateToLogin();
    await page.typeUsername(username);
    await page.typePassword(password);
    await page.submit()

    // page.getUsername().then((res) => {
    //   console.log("THIS IS A TEST")
    // })
    let actualUsername = await page.getUsername();
    expect(actualUsername).toEqual(username);
  });

  afterEach(async () => {
    // Assert that there are no errors emitted from the browser
    const logs = await browser.manage().logs().get(logging.Type.BROWSER);
    expect(logs).not.toContain(jasmine.objectContaining({
      level: logging.Level.SEVERE,
    } as logging.Entry));
  });
});

正如您在注释代码中看到的那样，我试图解决Promise并记录一条调试语句，但从未记录过任何语句。该应用程序的页面代码为：

export class AppPage {
  navigateTo() {
    return browser.get(browser.baseUrl) as Promise<any>;
  }

  getTitleText() {
    return element(by.css('title')).getWebElement().getText() as Promise<string>;
  }

  navigateToLogin() {
    return element(by.id("loginButton")).getWebElement().click()
  }

  typeUsername(username: string) {
    return element(by.id("username")).sendKeys(username);
  }

  typePassword(password: string) {
    return element(by.id("password")).sendKeys(password);
  }

  submit() {
    return element(by.id("loginSubmit")).getWebElement().click();
  }

  //the promise returned here never resolves
  getUsername() {
    return element(by.id('userMenu')).getText();
  }
}
