javascript - Unable to test .success function within controller -


i have simple controller , service performs http post. controller has .success , .error callbacks trying write unit tests:

to call btnclick:

<button ng-click="btnclick('cart')">click</button>

controller:

app.controller('mycontroller', function($scope, myservice, $timeout) {      $scope.btnclick = function (action) {          $scope.postdata = {"id": $scope.myid, "user": $scope.myuser};          $scope.cartrequest = function() {             $scope.disabled = true;             $scope.mytext = '';              myservice.postaction('cart', $scope.postdata)                 .success(function (data, status, headers, config) {                     $timeout(function(){                         $scope.disabled = false;                         $scope.mytext = 'inside timeout';                          $timeout(function(){                             $scope.hidebtn = true;                         }, 1400);                      }, 1500);                                     })                                     .error(function (data, status, headers, config) {                    $scope.carterror();                 });         };          switch(action) {             case "cart":                 $scope.cartrequest();                 break;         }     };

myservice:

 app.factory('myservice', function ($http) {      return {         postaction: function(uri, postdata) {             return $http({                 method: 'post',                 url: '/cartinfo/' + uri,                 data: postdata,                 headers: {'content-type': 'application/json'}             });         }     }; }); });

my test:

describe('cart api: can cart details', function () {     var myservice, httpbackend;      var customerinfo = {             "accountid" : "12345678901",             "username" : "mytestuser",             "firstname" : "joe",             "lastname" : "bloggs"     };      beforeeach(inject(function($rootscope, $controller) {         scope = $rootscope.$new();                  ctrl = $controller('mycontroller', {$scope:scope});          spyon(scope, 'btnclick').and.callthrough();          inject(function ($httpbackend, _myservice_, $timeout) {             myservice = _myservice_;             httpbackend = $httpbackend;             timeout = $timeout;         });     }));      it('should check if user logged in', function () {             scope.customer = customerinfo;         scope.btnclick('cart');          var returndata = {};         var result = {};         var mockdata = { "accountid" : scope.customer.accountid, "username" : scope.customer.username};          httpbackend.expectpost('/cartinfo/cart', mockdata, function () {             return {                 'content-type': 'application/json'             };         }).respond(200, returndata);                    myservice.postaction('unlock', mockdata).success(function (response) {             console.log("hello");             timeout.flush(1501);             scope.$apply();             expect(scope.disabled).tobefalsy();             expect(scope.mytext).toequal('inside timeout');         });      }); });

it seems though .success block within test never called 2 expects:

expect(scope.disabled).tobefalsy(); expect(scope.mytext).toequal('inside timeout');

dont seem run.

promises in specs assume specs should asynchronous. angular promises have tested synchronously:

    myservice.postaction('unlock', mockdata);     $rootscope.$digest();     timeout.flush();     // can omitted if scope watchers don't affect spec     // scope.$apply();     expect(scope.disabled).tobefalsy();     expect(scope.mytext).toequal('inside timeout');

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
