angularjs - Mocking a service call from a controller, Jasmine using the actual service -

i've trying test service called controller using spy , mock. jasmine's error appear it's trying call actual service? doing wrong?

controller

angular.module('vsapp').controller('kitsctrl', function ($scope, productsdataservice) {      productsdataservice.getproducts("kit").success(function (data) {          $scope.products = data;      });  }); 

spec

describe("kits controller", function () {      var productsdataservicemock, $controllerconstructor, scope;      beforeeach(module('vsapp'));      beforeeach(inject(function ($controller, $rootscope) {          $controllerconstructor = $controller;         scope = $rootscope.$new();         productsdataservicemock = {              getproducts: function(type) {return {};}         };      }));      it('should call products data service', inject(function () {          var ctrl = $controllerconstructor('kitsctrl', {$scope: scope, productsdataservice: productsdataservicemock});          spyon(productsdataservicemock, 'getproducts').andcallthrough();          expect(productsdataservicemock.getproducts).tohavebeencalled();      }));  }); 

error

typeerror: 'undefined' not function (evaluating 'productsdataservice.getproducts("kit").success(function (data) {              $scope.products = data;          })')         @ /**removed**/public/app/controllers/kitsctrl.js:9 

there 2 mistakes in test:

1. you spy on mock after having constructed controller, , after controller has called mock.
2. the controller expects service return object having success() method, mock returns empty object. so, when calling success(), since method doesn't exist, exception thrown.

my advice: don't create mock. spy on real service, , use real promise api rather soon-to-be-deprecated success/error callbacks:

angular.module('vsapp').controller('kitsctrl', function ($scope, productsdataservice) {      productsdataservice.getproducts("kit").then(function (data) {         $scope.products = data;     }); }); 

and

var $controller;  beforeeach(inject(function (_$controller_, $rootscope) {      scope = $rootscope.$new();     $controller = _$controller_; }));  it('should call products data service', inject(function(productsdataservice, $q) {     spyon(productsdataservice, 'getproducts').andreturn($q.when('somedata'));     $controller('kitsctrl', {$scope: scope});      expect(productsdataservicemock.getproducts).tohavebeencalledwith('kit');     expect($scope.products).tobe('somedata'); }));
