Grunt Test Task - angularjs

Question

i have set up a grunt task for running test using Karma and Jasmine for testing an AngularJS framework!
For some reasons same configurations i have used for other projects fails for this one. here is the error message am getting:

my test is :

/*global module: false, inject: false */
describe('utility', function(){
var utility;
beforeEach(module('eha.van.utility'));
beforeEach(inject(function(_utility_){
utility = _utility_
}));
it('should be defined', function(){
expect(utility).toBeDefined();
});
