Testing Ember.js files with JUnit

Mainly asking if this is possible, since I have always thought that JS files would be tested with a JS unit test framework, just like Java files would be tested with Java unit test frameworks. From quite a bit of Google searches I've only found results for plugins and this example: http://ift.tt/1NFYQCG

1. Is unit testing something like Ember files possible in a Java-based framework like JUnit?

2. Is there a way to convert QUnit tests to JUnit tests?
