Symfony Playgound with its Container and a custom configuration

test.php

<?php

use App\Kernel;

require __DIR__.'/vendor/autoload_runtime.php';

use Symfony\Component\Console\Output\StreamOutput;
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface;
use Symfony\Component\DependencyInjection\ContainerBuilder;

return function () {
    $k = new class('dev', true) extends Kernel implements CompilerPassInterface {
        public function process(ContainerBuilder $container)
        {
            $container->getAlias('logger')->setPublic(true);
            $container->getDefinition('monolog.handler.console')->setPublic(true);
        }
    };
    $k->boot();
    $c = $k->getContainer();

    $c->get('monolog.handler.console')->setOutput(
        new StreamOutput(fopen('php://stdout', 'w'),
        StreamOutput::VERBOSITY_VERY_VERBOSE,
    ));

    $logger = $c->get('logger');
    $em = $c->get('doctrine.orm.entity_manager');

    // Start of playground
};

Sorry my stupidity, but what is for?

I often need to test "something" in my application, and it helps me to test that thing.

For example

• Do I setup my CASCADE relation in the good direction : what does happen when I delete a project, does it also delete the organization
• How does my Doctrine type behave if my column is empty
• etc

It could be also solved with

• an integration test
• a custom debug command
• a custom debug controller
• etc.

But I have this habit for a very long time, and I like to be able to "hack" and prototype quickly. So in almost every projects I work on have this test.php file.

Oh ok, gotcha you.

Very good! Thanks you.
It is worth mentioning that this command can be executed using symfony php test.php

Very useful, thx for sharing! 🔥
