Jasmine AngularJS : Mock a $scope property? -

i've got angularjs controller :

        app.controller('myctrl', function($scope, myfactory){               $scope.types = myfactory.gettypes();                 $scope.model= {};                 $scope.model.type = $scope.types[0].type;      }); }); 

everything works fine.

but want test controller in jasmine. mock myfactory , init myctrl that:

 describe('controllers: myctrl', function () {          var myctrl, mockedfactory, scope;          beforeeach(module('app.factories', function ($provide) {             mockedfactory = {                 gettypes: function(){}             };              spyon(mockedfactory, 'gettypes');             $provide.value('myfactory', mockedfactory);         }));          beforeeach(module('app'));          beforeeach(inject(function ($rootscope, $controller) {             scope = $rootscope.$new();             myctrl= $controller('myctrl', {                 $scope: scope             });         }));          it('should call accordtypefactory.getavailabletypes()', function () {             scope.types;             expect(mockedfactory.gettypes).tohavebeencalled();         }); 

but i've got logic bug : cannot read property 0 of undefined

i understand bug; because mock factory controller property $scope.model.type it's undefined because use result of factory through $scope.types.

my question simple: how can make work test ?

thx guys

    beforeeach(module('app.factories', function ($provide) {         mockedfactory = {             gettypes: function(){ return [{}]; }         };          spyon(mockedfactory, 'gettypes').andcallthrough();         $provide.value('myfactory', mockedfactory);     })); 

if understood correctly problem mock not return array while controller expects there @ least 1 element in it. set mock return array element , use andcallthrough() on spy have call mock.

if possible factory can return empty arrays while application running, you'd want check array contains @ least 1 element before trying access types[0]
