Github user tzolov commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/206#issuecomment-134072279 @Leemoonsoo thanks for the references. If not mistaken the [test controllers and directives](https://github.com/apache/incubator-zeppelin/tree/master/zeppelin-web/test) doesn't contain any real controller tests at the moment. As i've mentioned earlier i'm not much of js/angular authority and would prefer to learn from someone else's experience and examples. @djoelz do you feel like you can help here? Otherwise we can review and merge this and postpone the tests for after someone provide an example such?
