如何在TestCafe中等待直到angular执行？

const waitForAngular = ClientFunction(() => {
  return new Promise((resolve, reject) => {
    const interval = setInterval(() => {
      if (window.angular && window.angular.resumeBootstrap) {
        clearInterval(interval);
        resolve();
      }
    }, 100);
  });
});

import { Selector } from 'testcafe';

fixture `My Fixture`
    .page `http://example.com`;

test('My Test', async t => {
    await waitForAngular();

    // 在这里执行与Angular相关的测试步骤

    const element = Selector('#myElement');
    await t.expect(element.exists).ok();
});
