Test an Angular Component with $componentController

Traditionally you had to create DOM elements to test a directive but by shifting our focus to components, writing unit tests got a lot easier using $componentController within ngMocks. We can now test our component's controller with an easy to use API that does not require us to spin up any DOM elements to do so. In this lesson, we will see how our ES6 tests are transpiled, learn how to test a component using $componentController and talk about how to simulate lifecycle hooks.
