在量角器测试期间禁用角度材质2动画

Question

Angular Version 5.2.3

Protractor和Angular的新手，在设置测试时遇到问题。我只能想象这可能是由于动画问题导致测试速度变慢，因为测试有时会过去。也许我需要采取不同的方法，但目标是看我是否可以排序表。有没有办法禁用动画？我尝试使用element.all(locator).allowAnimations抛出一个Angular未定义错误。

it('should sort full name column', async () => { // ignoring for now until figure out a way to wait until table sorts
await listUserPage.navigateTo();

await browser.wait(EC.presenceOf(listUserPage.userTable));
const unsortRows: string[] = [];
const sortRows: string[] = [];

// get all values of full name column
await listUserPage.tableRows.each(async (row) => {
const col = row.all(by.tagName('mat-cell')).get(0);
  unsortRows.push(await col.getText());
});

// sort in order we expect
unsortRows.reverse();

await listUserPage.clickFullNameSort();
await listUserPage.clickFullNameSort();   // need to click twice, once for asc then again for desc
await browser.driver.sleep(500);

await listUserPage.tableRows.each(async (row) => {
  const col = row.all(by.tagName('mat-cell')).get(0);
  sortRows.push(await col.getText());
});
