php - Symfony Console Ask helper not working if called from composer -

in application i'm using symfony/console package (v. 3.2.7) , created several commands works fine.

now i'm trying automate tasks , added in composer.json scripts sections

 "scripts": {         "test": [             "@php app/console myproject:setup"         ]     } 

and code in command is

<?php namespace myproject\command; use symfony\component\console\command\command; use symfony\component\console\input\inputinterface; use symfony\component\console\output\outputinterface; use symfony\component\console\question\confirmationquestion;  /**  * class setupcommand  * @package wpskeletoncli\command  */ class setupcommand extends command {     protected function configure()     {         $this->setname('myproject:setup');         $this->setdescription('a setup wizard brand new skeleton based project.');     }      protected function execute(inputinterface $input, outputinterface $output)     {         $this->gethelper('question')->ask($input, $output, new confirmationquestion('are displaying question?', false));     } } 

if run command console, works fine, if run command in same way composer doesn't work, displays no errors , question not showed. tried add print command know if command call , can see print examples (both methods).

i red scripts section on composer, thing noticed i'm not using composer event object.

maybe symfony question helper not compatible running script composer?
