Unit-test Karma about Parse.com on AngularJS

Question

I am very new about AngularJs, Parse and Karma.This time the problem I meet I didn't search the similar solution online. So I hope anyone good at these parts can help me. To make the Parse can run in my project, I install the angular-parse-patch from this site: https://github.com/mcwebb/angular-parse-patch Then it works and I can use Parse in my project. However, I am doing the unit-test now and when I use Karma test the controller which contains the Parse code. The error generated.

Error: Parse SDK not available

I guess it caused by the Karma didn't connect the path of the parse-patch.
