EmberJS - Unit testing a component

I am new to writing unit tests.

I am trying to write a unit test for a tooltip Ember component. The usage pattern is

<div id="parent"> I have a tooltip</div>
{{tooltip-comp}}
    tooltip content
{{/tooltip-comp}}

I am trying to check that clicking the parent div (with id parent), makes the 'isVisible' property true for the component.

Do I need to somehow insert a parent to DOM to be able to do this?

I am using Ember CLI.
