How to unit test if an angular 2 component contains another component
<p>I'm quite new to angular 2.</p>

<p>I have a component which in turn has some other components in its template.</p>

<p>How do I write unit tests to check if my parent component consists of other components.</p>

<p>Mentioning a sample or directing me to a resource would be really helpful.</p>

<p>MyComponent.ts:</p>

<pre><code>import { Component } from '@angular/core';
@Component({
selector: 'my-component',
templateUrl: `&lt;div&gt;
&lt;other-component&gt;&lt;/other-component&gt;
&lt;/div&gt;`
})
export class MyComponent{

}
</code></pre>

<p>OtherComponent.ts:</p>

<pre><code>import { Component } from '@angular/core';
@Component({
selector: 'other-component',
templateUrl: `&lt;div&gt;
&lt;h1&gt;Other Component&lt;/h1&gt;
&lt;/div&gt;`
})
export class OtherComponent{

}
</code></pre>
