karma runner - Jasmine: Function with transformResponse/resolve -

i have function in controller:

function get(request) {     return userservice.get({                      id: request.id,                      transformresponse: function(data) {                          return angular.fromjson(data);                      }                     }); }; 

and test this:

var $scope; var controller; var userservice;  beforeeach(function() {    angular.mock.module(function($provide) {        userservice = jasmine.createspyobj('userservice', ['get']);         $provide.value('userservice', userservice);    }); });  beforeeach(inject(function($rootscope, $controller, userservice) {     $scope = $rootscope.$new();     controller = $controller('...' {         $scope: $scope,         userservice: userservice     });      $scope.$digest(); }));  it('should call user service function when getting user', function() {     var request = { id: 5 };     controller.get(request);      expect(userservice.get).tohavebeencalledwith(request); }); 

test passed, karma coverage display function transformresponse not covered test. how must correctly mock function? thanks!
