Javascript 忽略量角器中的异步等待

一般来说，我对测试和JS都是新手。我正在尝试编写我的第一个异步等待测试，但我无法使它工作

我已设置了

量角器.promise.USE\u promise\u MANAGER=false

；要能够使用

异步等待

当我将selenium promise manager设置为false时，我收到了预期的错误

TypeError:无法创建托管承诺实例：selenium\u promise\u manager环境变量已禁用承诺管理器：未定义。

然而，当我向代码中的所有抽象层添加AsyncWait时，同样的错误仍然存在。如何使用

async await

使以下测试工作

login.spec.js

protractor.promise.USE_PROMISE_MANAGER = false;

describe('Login page :', () => {
  const loginPage = new objects.Login(),
        el = new objects.Element(),
        ec = new objects.ExpectedCondition()


  beforeAll( async () => {
    await loginPage.go();
  });

  describe('with invalid credentials', () => {

    beforeEach( async () => {
      await browser.refresh();
    }); 

    it('should fail to log in without credentials', async () => {
      await loginPage.submit();

      await expect(ec.isVisible(loginPage.selectors.login.errors.lblEmailValidation));
      await expect(ec.isVisible(loginPage.selectors.login.errors.lblPasswordValidation));

此设置似乎不会从一组测试更新到另一组测试。我们在不同的路径中有两组测试，每个测试都有单独的dragrator.conf文件，其中一组为false。除此PROMISE\u管理器外，所有设置均被选中。我们颠倒顺序，第一个设置规则第二个测试集。请随意在量角器中创建关于SO和/或问题的新问题。此设置似乎不会从一组测试更新到另一组测试。我们在不同的路径中有两组测试，每个测试都有单独的dragrator.conf文件，其中一组为false。除此PROMISE\u管理器外，所有设置均被选中。我们颠倒顺序，第一个设置规则第二个测试集。请随意在量角器回购中创建关于SO和/或问题的新问题
