Struggling to get started on AngularJS unit testing -

i followed post (http://gonehybrid.com/how-to-write-automated-tests-for-your-ionic-app-part-2/) create simple unit test using karma & jasmine ionic controller, keep getting undefined errors while stated objects have been defined. i'm missing obvious? way, i'm able run referenced tests blog above makes me think i'm missing in mine.

errora follows:

1. typeerror: undefined not object (evaluating 'authmock.login') in /users/projects/app/tests/unit-tests/login.controller.tests.js (line 65)
2. typeerror: undefined not object (evaluating 'deferredlogin.resolve') in /users/projects/app/tests/unit-tests/login.controller.tests.js (line 71)
3. typeerror: undefined not object (evaluating 'deferredlogin.reject') in /users/projects/app/tests/unit-tests/login.controller.tests.js (line 79)

here's controller:

    angular.module('app').controller('loginctrl', function($scope, $state, $ionicpopup, $auth) {   $scope.logindata = {};   $scope.user = {       email: '',       password: ''     };      $scope.dologin = function(data) {       $auth.login(data).then(function(authenticated) {         $state.go('app.tabs.customer', {}, {reload: true});       }, function(err) {         var alertpopup = $ionicpopup.alert({           title: 'login failed!',           template: 'please check credentials!'         });       });     };  }); 

here's test:

    describe('loginctrl', function() {      var controller,         deferredlogin,         $scope,         authmock,         statemock,         ionicpopupmock;      // load module our app     beforeeach(angular.mock.module('app'));      // disable template caching     beforeeach(angular.mock.module(function($provide, $urlrouterprovider) {         $provide.value('$ionictemplatecache', function(){} );         $urlrouterprovider.deferintercept();     }));      // instantiate controller , mocks every test     beforeeach(angular.mock.inject(function($controller, $q, $rootscope) {         deferredlogin = $q.defer();      $scope = $rootscope.$new();          // mock dinnerservice         authmock = {             login: jasmine.createspy('login spy')                           .and.returnvalue(deferredlogin.promise)         };          // mock $state         statemock = jasmine.createspyobj('$state spy', ['go']);          // mock $ionicpopup         ionicpopupmock = jasmine.createspyobj('$ionicpopup spy', ['alert']);          // instantiate logincontroller         controller = $controller('loginctrl', {             '$scope': $scope,             '$state': statemock,             '$ionicpopup': ionicpopupmock,                         '$auth': authmock           });      }));      describe('#dologin', function() {          // call dologin on controller every test         beforeeach(inject(function(_$rootscope_) {              $rootscope = _$rootscope_;              var user = {                 email: 'test@yahoo.com',                 password: 'test'             };              $scope.dologin(user);          }));          it('should call login on $auth service', function() {              expect(authmock.login).tohavebeencalledwith(user);         });          describe('when login executed,', function() {             it('if successful, should change state app.tabs.customer', function() {                  deferredlogin.resolve();                 $rootscope.$digest();                  expect(statemock.go).tohavebeencalledwith('app.tabs.customer');             });              it('if unsuccessful, should show popup', function() {                  deferredlogin.reject();                 $rootscope.$digest();                  expect(ionicpopupmock.alert).tohavebeencalled();             });         });     }) }); 

here's karma config:

    files: [   '../www/lib/ionic/js/ionic.bundle.js',   '../www/lib/angular-mocks/angular-mocks.js',   '../www/js/*.js',   '../www/js/**/*.js',   'unit-tests/**/*.js' ], 

i think controller tests undefined. try replace first function , check if defined.

it('controller defained', function() {             expect($controller).tobedefined(); }); 

if isn't, try call controller with:

$controller = _$controller_;
