Angular2 @Viewchild unit test

I have a component like this:

export class ParentComponent implements OnInit, OnDestroy {


    @ViewChild(ChildComponent) childComponent: ChildComponent;
}

which is using the childComponent to make a call, let's say like this:

this.childComponent.method();

within ParentComponent method.

So, when I am trying to test the ParentComponent method which is internally using the ChildComponent, the childComponent is returning as undefined.

How to resolve the issue?

Declare fixture for child component inside describe. 

let childFixture: ComponentFixture<childComponent>;

And now create component instance using

let childComp = childFixture.componentInstance;
