How to unit test the checkbox in Angular2

I have a sample code for checkbox written with Angular2.

<div class="col-sm-7 align-left" *ngIf="Some-Condtion">
    <input type="checkbox" id="mob_Q1" value="Q1" />
    <label for="mob_Q1">Express</label>
</div>

I want to unit test the above checkbox. Like I want to recognize the checkbox and test whether it is check-able. How do I unit test this with Karma Jasmine?
