jasmine unit testing was method called

I have a simple unit test I am trying to write. I simply need to test if my function was called. In my service I have a simple method that calls another method like so

svc.getNewestNotifications = function getNewestNotifications() {
    getNewNotifications(username);
};

in my test:

describe('notification service tests', function () {
    var $rootScope, $http, $q, notificationSvc, $httpBackend;
    beforeEach(module('myApp'));
    beforeEach(inject(function(_$rootScope_,_$http_,_$httpBackend_,_$q_,_$sce_,_notificationsFeedService_){
    $rootScope = _$rootScope_;
    $httpBackend = _$httpBackend_;
    $http = _$http_;
    $q = _$q_;
    notificationSvc = _notificationsFeedService_;
    _scope_ = $rootScope.$new();
    $scope = _scope_;

    $httpBackend.whenGET(/\.html$/).respond('');

}));

describe("getNewestNotifications test", function() {
        it('calls the getNewestNotifications when scroll to top', function() { 
            spyOn(notificationSvc, 'getNewestNotifications').and.callThrough();
            expect(notificationSvc.getNewestNotifications).toHaveBeenCalled();
        });
    });   

}

Its the " describe("getNewestNotifications test", function() {} " block that is my issue. I get "Expected spy getNewestNotifications to have been called." in the console. I am very new to unit testing in general and I am at a complete loss as to why I am seeing this i am simply trying to test that the method was indeed called. Any help?
