php - How to test a symfony form type with constructor -


i'm struggle typetestcase symfony testing form type constructor. while offical solution registring form service works in application, same form type cannot tested typetestcase. since typetestcase extends formintegrationtestcase , extends \phpunit_framework_testcase instead kerneltestcase. formfactory in typetestcase doesn't/can't forms registered services , throw error calling phpunit:

tests\demobundle\form\type\demotypetest::testsubmitvaliddata missing argument 1 demobundle\form\type\demotype::__construct(), called in /var/www/vendor/symfony/symfony/src/symfony/component/form/formregistry.php on line 90 , defined

the way i've see not serving dependency via constructor using optionsresolver in configureoptions set required element setrequired method dependency.

here relevant parts code:

demotype.php

[...] class demotype extends abstracttype {     /**      * @var entitymanager      */     protected $entitymanager;      public function __construct($entitymanager)     {         $this->entitymanager = $entitymanager;     } [...]

services.yml

app.form.type.demo:     class: demobundle\form\type\demotype     arguments: ["@doctrine.orm.entity_manager"]     tags:         - { name: form.type }

demotypetest.php

[...] class demotypetest extends typetestcase {      protected function getextensions()     {         $classmetadata = $this->getmock(classmetadata::class, [], [], '', false);         /* @var validatorinterface|\phpunit_framework_mockobject_mockobject $validator */         $validator = $this->getmock(validatorinterface::class);         $validator->method('validate')->will($this->returnvalue(new constraintviolationlist()));         $validator->method('getmetadatafor')->will($this->returnvalue($classmetadata));         return [             new validatorextension($validator),         ];     }      public function testsubmitvaliddata()     {         $formdata = [             'some' => 'data',         ];          $form = $this->factory->create(demotype::class);  [...]

you can instantiate formtype , pass form factory, described in doc.

you can mock doctrine entity manager, example:

public function testsubmitvaliddata() {   // mock formtype: entity   $em = $this->getmockbuilder('\doctrine\orm\entitymanager')       ->disableoriginalconstructor()       ->getmock();      $type = new demotype($em);     $formdata = [         'some' => 'data',     ];      $form = $this->factory->create($type);     ...

a sample mocking doctrine object stack simulate repo method can take @ this answer or ask :)

hope help

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 ...
