command is not executed in a controller - symfony

Question

I would like to run a command via a controller. My command run normaly in cli (tests are done)
My controller call the command and I got immediately
[OK] success
from the command return but tests did not run.
my controller
`
<?php
namespace App\Controller\Api;
use OpenApi\Annotations as OA;
use Symfony\Component\Console\Output\ConsoleOutput;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpKernel\KernelInterface;
use Symfony\Component\Process\Process;
use Symfony\Component\Routing\Annotation\Route;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\BufferedOutput;
class UnitTestController extends AbstractController
{
private $kernel;
public function __construct(KernelInterface $kernel)
{
$this->kernel = $kernel;
}
#[Route('/unit_tests', name: 'unit_test', methods: 'GET')]
public function unitTest(): Response
{
$application = new Application($this->kernel);
$application->setAutoExit(false);
$input = new ArrayInput([
'command' => 'mapi:unitTests',
]);
$output = new BufferedOutput();
$application->run($input, $output);
// return the output, don't use if you used NullOutput()
$content = $output->fetch();
dd($content);
}
}
`
and my command
`
<?php
namespace App\Command;
use Symfony\Component\Console\Attribute\AsCommand;
use Symfony\Component\Console\Command\Command;
use Symfony\Component\Console\Input\InputInterface;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\Console\Style\SymfonyStyle;
use Symfony\Component\Process\Process;
use Symfony\Contracts\HttpClient\Exception\ClientExceptionInterface;
use Symfony\Contracts\HttpClient\Exception\DecodingExceptionInterface;
use Symfony\Contracts\HttpClient\Exception\RedirectionExceptionInterface;
use Symfony\Contracts\HttpClient\Exception\ServerExceptionInterface;
#[AsCommand(
name: 'mapi:unitTests',
description: 'lancement des tests unitaires',
)]
class unitTestCommand extends Command
{
/**
* #param InputInterface $input
* #param OutputInterface $output
* #return int
* #throws ClientExceptionInterface
* #throws DecodingExceptionInterface
* #throws RedirectionExceptionInterface
* #throws ServerExceptionInterface
*/
protected function execute(InputInterface $input, OutputInterface $output)
{
$io = new SymfonyStyle($input, $output);
ini_set('max_execution_time', 300);
$process = Process::fromShellCommandline('php vendor/bin/phpunit');
$process->run();
$io->success('success');
return Command::SUCCESS;
}
}
edit: no error, unit tests from command are not executed. when I run the command from the cli, everything is ok
