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.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...

python - How to get a widget position inside it's layout in Kivy? -

i have gridlayout , added image widgets on after adding of images want draw rectangle in each image using canvas couldn't because don't know exact image widgets positions on gridlayout. code: http://paste.ofcode.org/3bdp9yhjrcrzmsztbu9hqp4 http://paste.ofcode.org/3az3gx4fxzr9dlhe2ami97c in last line of python code : rectangle(pos = (child.x - 2.4, child.y + 467), size = (70, 70)) how draw rectangle in child(my method not good^), also why gridlayout not coming in center after setting it's pos_hint = {"center_x" : .5}? if understand question right, try use such methods to_local() , to_parent() , to_widget() , to_window() . try substract position of gridlayout widgets' positions.
