      - Failed: Angular could not be found on the page http://127.0.0.1:57025/.If this is not an Angular application, you may need to turn off waiting for Angular.
                                Please see 
                                https://github.com/angular/protractor/blob/master/docs/timeouts.md#waiting-for-angular-on-page-load
      - Failed: Error while waiting for Protractor to sync with the page: "both angularJS testability and angular testability are undefined.  This could be either because this is a non-angular page or because your test involves client-side navigation, which can interfere with Protractor's bootstrapping.  See http://git.io/v4gXM for details"
