Question

我尝试设置一些简单的 protractor 测试，尝试使用Angular2进行E2E测试。我使用以下版本：（ v4.4.3 NG2 / v5.1.2量角器）。

我还使用最新的@angular/cli版本和premade protractor.conf.js 文件。

以下是我使用现有应用程序设置的简单测试。

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

describe('Protractor testing suite with TypeScript', () => {
  beforeAll(() => {
    browser.get('/');  

    // Add logging.
    browser.manage().logs().get('browser').then(function (browserLog) {
      console.log('log: ' + require('util').inspect(browserLog));
    });
  });

  describe('Protractor first test suite', function () {
    it('should navigate to the map', function () {
      const navigationMapButton = element(by.id('general.menu.esri_maps'));
      navigationMapButton.click();

      // Testing the navigation to another page here (The page is lazy-loaded, that might be linked)
      browser.wait(() => {
        return browser.getCurrentUrl().then((url) => {
          console.log(url);
          return url.includes('esrimaps');
        })
      })
        .then((resolved) => {
          expect(resolved).toBeTruthy();
        });
    });
  });
})

主要问题是50％的时间，测试失败，而另一次，它的工作原理。以下是日志：

附加信息：

当失败时，显然它是因为它在尝试导航时超时，但在Web驱动程序实例上，它每次都在click()上成功导航。很明显，它以某种方式失去对正在发生的事情的追踪，但我无法指出是什么导致这种情况发生......
加载时间之间有一个加载器，所以它可能已经链接了吗？（我使用根据我的需求定制的NG2管理模板：https://github.com/akveo/ngx-admin）
正如我之前所说，信息中心和地图是延迟加载的，所以它可能已被链接了吗？
我已经看到了这个链接：https://github.com/angular/protractor/blob/master/docs/timeouts.md关于超时，但我不知道我应该实现哪个用例...我真的需要在任何地方更改我的代码才能使用{{ 1}}用于异步任务？因为这个问题而改变一切似乎真的很烦人......

好吧，实际上我用最糟糕的例子来尝试我的测试。我可能是因为懒惰的装载或类似的其他机制，但根本没有：我的地图是使用 ArcGIS JS API 的 Esri 地图，由于ArcGIS JS API通过Dojo提供，因此该地图通过angular-esri-loader库提供。

因此，它不完全是一个角度上下文，我不得不使用browser.waitForAngularEnabled(false);来使它工作。

量角器简单测试可在50％的时间内工作
