karma/angularjs how to test run block with an asynchronous service -

how can test like:

init.js lama.system module

angular.module('lama.system', [])    .config(['$httpprovider', function($httpprovider) {         // crossdomain requests not allowed if want cors request see filter.php          $httpprovider.defaults.headers.common['x-requested-with'] = 'xmlhttprequest';     }])     .run(['$rootscope', '$state', '$log', 'global',function ($rootscope, $state, $log, global) {         $rootscope.$state = $state;         $rootscope.$log = $log;         $rootscope.global = global;     }]); 

controllers.js lama.system module

angular.module('lama.system')     .controller('systemcontroller', ['$scope',         function($scope) {            $scope.test =[];           }     ]); 

services.js lama.system module

angular.module('lama.system')     .factory('menus', ['$http', function($http) {         return {             query : function(menus){                 return $http.get('/api/v1/user/menus', {                     params: {                         'menus[]': menus                     }                 });             }         };      }]); 

system.js router

//setting route angular.module('lama.system')     .config(['$stateprovider', '$urlrouterprovider',         function($stateprovider, $urlrouterprovider) {             $urlrouterprovider.otherwise('/');             $stateprovider                           .state('home', {                 url: '/',                 templateurl: 'system/views/home.html',                 controller:'systemcontroller'             });         }     ]); 

init.js lama module

angular.module('lama', ['ui.router','restangular','lama.system','lama.users'])     .run(['$rootscope',  'menus',function ($rootscope, menus) {        // default hard coded menu items main menu            var menus = [             {                 'permission': null,                 'title': 'home',                 'link': 'home'             },             {                 'permission': 'users',                 'title': 'user',                 'link': 'user_actions.list'             }             ];              $rootscope.menus = [];              function querymenu(menus) {                 menus.query(menus).then(                     function (result) {                         $rootscope.menus = result.data;                      },                     function (reason) {                         throw new error(reason);                     }                     );             }              // query server menus , check permissions             querymenu(menus);             $rootscope.$on('loggedin', function(event,user) {                 console.log('kkk');                 querymenu(menus);                  $rootscope.global = {                     user:  user,                     authenticated: user.groups.length,                     isadmin:  user.groups.indexof('admins')                 };             });       }]); 

the test

(function() {     describe('unit test: system module', function () {         describe('systemcontroller', function () {              // load controller's module             beforeeach(function() {                 module('lama');                 module('statemock');             });              var systemcontroller,             $rootscope,             $scope,             $httpbackend;              // initialize controller , mock scope             beforeeach(inject(function ($controller, _$rootscope_, _$httpbackend_) {                 $rootscope = _$rootscope_;                 $scope = _$rootscope_.$new();                 $httpbackend = _$httpbackend_;                 systemcontroller = $controller('systemcontroller', {                     $scope: $scope                 });                 $httpbackend.when('get', '/api/v1/user/menus').respond(200,{});             }));              it('should attach list of awesomethings scope', function () {                 expect($scope.test.length).tobe(0);             });              it('should expose global scope', function() {                 expect($rootscope.global).tobetruthy();             });         });      }); }()); 

that give me :(

nb

i'm using ui-router

i've taken @ source code. primary offending item is:

angular.element(document).ready(function() {   angular.bootstrap(document, ['lama']); }); 

by including manual bootstrap in files karma imports, app un-necessarily being bootstrapped within karma test environment. so, instead, move lama module separate file, , omit init.js files included karma.

there couple of other design concerns causing excessive test setup. when testing systemcontroller there no need include lama.system module (as controller belongs to). test setup controller can simple as:

var $scope, $rootscope;  beforeeach(module('system.lama'));  beforeeach(inject(function($controller, _$rootscope_) {   $rootscope = _$rootscope_;   $scope = $rootscope.$new();   $controller('systemcontroller', {$scope: $scope}); })); 

you note in isolating lama.system module above, error $state cannot injected (not found). because module definition should instead be:

angular.module('lama.system', ['ui.router']) 

(a module should not require presence of module own dependencies, else can never function in isolation).

one final observation on mocking lama module run block. strictly speaking should stub service query method entirely , not part of implementation, else test isolated. therefore, instead, better following:

beforeeach(module(function($provide) {   $provide.decorator('menus', function($delegate, $q) {      // overwrite query method      $delegate.query = function() {        return $q.when([{id: 1, name: 'bob'}]);      };          return $delegate;    }); })); 

this way, don't need worry using $httpbackend @ all.
