Question

我正在使用量角器和Angular设置e2e测试。在这里，我正在套件中编写3个测试用例。当只有2个时，它运行良好。除此之外，它还会因超时错误而失败。我什至尝试实现“完成”的回调函数，但无法解决。奇怪的是，如果我按照所有3个测试用例通过的顺序重新排列测试用例。例如，请参见下面的代码。

app.po.ts

import { browser, by, element } from 'protractor';

export class TestEngine {
  navigateTo() {
    browser.get('/');
    var script = "window.localStorage.setItem('isAccepted', 'true')";
    return browser.executeScript(script);
  }

  getParagraphText() {
    return element(by.css('page-welcome p')).getText();
    }

  getButtons() { 
      return element(by.buttonText('Login')).getText();
  }

  getButtonsClick() {
      return  browser.actions().mouseMove(element(by.tagName('b'))).click();
        }

}

test-e2e.spec.ts

    import { TestEngine } from './app.po';

    describe('Test Engine App', () => {
      let page: TestEngine;

      beforeEach(function (done) {
        setTimeout(function () {
          page = new TestEngine();
          done();
        }, 1);
      });

//1. Promise included

      it('should display the question for Validation', function (done) {
        page.navigateTo();
        page.getParagraphText()
          .then((text) => {
            expect(text).toEqual('Want to validate an engine?');
            done();
          });
      });

// 2. Promise included

      it('should display a button which is used for Validation', function (done) {
        page.navigateTo();
        page.getButtons().
          then((text) => {
            expect(text).toEqual('Login');
            done();
          });
      });

 //3. Promise not included   

      it('should click on the button which is used for Login', function (done) {
        page.navigateTo();
        page.getButtonsClick()
        done();
      });

    });

场景上面的测试用例1,2,3出现错误时指出

Test Engine App
    √ should display the question for Validation
    √ should display a button which is used for Validation
    × should click on the button which is used for Login

但是，如果我使用 fit 或 xit 分别运行所有3个，则每种情况都会通过，并且如果我以1-> 3-> 2的顺序通过交换来运行第三个测试用例带有2nd，然后全部通过。

我在这里做错了什么？回调函数done（）;是否放置在正确的位置？因为在这个规范文件中，我计划有100多个测试用例。所有都会包括涉及的承诺。

批量运行时，量角器中出现超时错误，但单独运行时，它工作正常吗？
