Putting together Webstorm, Karma and Ember

I’m trying to put together webstorm karma and Ember.

I think I’ve to create two karma configuration files, one for unit testing and another one for integration/acceptance testing.

My main question is “where to test the app”, eg before build process (including tests and app folder stuffs) or after the build process (including assets folder stuffs)?

Is a good idea to mimic the behavior of ember-cli-karma?

Thanks a lot!
