modal-select tests: help wanted!

[bianchimro]

The situation about tests is the following:

• Testing environment has been setup with gulp and karma
• Only tests for the compile directive have been added (in tests/compile-directive.tests.js)
• The rest of the project completely lacks tests

I've put some effort in trying to write tests for the main modal-select directive, but couldn't get to a good solution about testing the code.
Sadly, this reflects my poor experience with testing of js code of a component like this one. This case, in particular, is hard to handle for me for the followin reason: It's not very clear to me how to test the component without user interaction, as it has very strong dependencies on some ionic directives and services such as $ionicModalSelect and collection-repeat

Anyone can help on this?
