Error: [$injector:unpr] Unknown provider: DSProvider <- DS <- Users <- UserServices

[kim2014]

I wrote the unit test for my angular JS controller and It complained about

Error: [$injector:unpr] Unknown provider: DSProvider <- DS <- Users <- UserServices

I ran the unit test by the karma command:
karma run test/karma.conf.js

Attached all of my directives, controller and my unit test
DSProvider.zip

Change this:

angular.module('ps.users.services', ['ngResource']);

to this:

angular.module('ps.users.services', ['ngResource', 'js-data']);
