Proper testing of Angular JS applications with ES6 modules

Testing of Angular JS application used to be quite painful especially when using “official” solutions like Karma or Protractor. ES6 (aka ES2015, aka new Javascript release) changed this by introducing standardized module syntax. This enables us to do real unit testing of Angular JS constructs like controllers, factories or services in a very simple and fast fashion. Check out the Github repository for implementation of the concepts described in this post.
