test cases failing when running ng test in angular2.0 with angular2-material components
<p>I am using angular2.0 in my application</p>

<p>I installed angular2-material components and imported in required modules</p>

<p>I tried writing test case for one of my components </p>

<p>//about.component.html</p>

<pre><code>&lt;md-card&gt;
    &lt;h3&gt;{{title}}&lt;/h3&gt;
    &lt;md-card-content&gt;
           &lt;button md-raised-button class="md-raised md-primary primary-bg" (click)="fnnavigate()"&gt;CHOOSE &lt;/button&gt; 
    &lt;/md-card-content&gt;
&lt;/md-card&gt;
</code></pre>

<p>//about.component.ts</p>

<pre><code>import { Component, OnInit } from '@angular/core';
import { Router} from '@angular/router';

@Component({
  selector: 'app-about',
  templateUrl: 'about.component.html',
  styleUrls: ['about.component.css']
     })

    export class AboutComponent implements OnInit {

  constructor(
    private router: Router
  ) { }

  title:string="welcome";

  ngOnInit() {

  }

  fnnavigate() {
    this.router.navigateByUrl('app/home1');
  }
}

<p>when I do <code>ng test</code>, I get:</p>
