+import { Observable } from 'rxjs/Observable';
 
 export class RouterStub {
   url: string;
   //noinspection TypeScriptUnresolvedFunction
   navigate = jasmine.createSpy('navigate');
   parseUrl = jasmine.createSpy('parseUrl');
+  events = Observable.of({});
   navigateByUrl(url): void {
     this.url = url;
   }
