[JMS serializer] how to set naming strategy

     public function serialize($object, array $serializationGroups)

    {

        $serializer = SerializerBuilder::create();

        $serializer->setPropertyNamingStrategy(new SerializedNameAnnotationStrategy(new IdenticalPropertyNamingStrategy()));

        $serializer->addMetadataDir($this->configDir . "/serializer", 'App\Entity');

        $serializer->setCacheDir($this->cacheDir . "/jms_serializer");

        $serializer = $serializer->build();

        $group = new GroupsExclusionStrategy($serializationGroups);

        $context = SerializationContext::create();

        $context->addExclusionStrategy($group);

        return $serializer->serialize($object, 'json', $context);

    }

It will make JSON string where property field is camelCased instead of Snake_cased. I highly recommend to use 'App\Entity' in addMetadataDir() because by default in Symfony jms_serializer.yaml config is set 'namespace_prefix' in metadata node, and without 'App\Entity' argument YML/XML entity configs won't work. It is also example how to customize Serializer parameters manually with SerializerBuilder without framework config.

[Symfony] Cannot read index 'email' from object of type App\Entity\User because it doesn't implement \ArrayAccess

                'data_class' => User::class,

[Symfony] Cannot login at Test environment - fix (in Behat)

When you trying to login in Test env, and it does not show any error (you was returned on login form again), and you does not have anything in logs, except Guard authenticator does not support the request. {"firewall_key":"main","authenticator":"App\\Security\\AppAuthenticator"}, you can try this.

 I removed lines:

        storage_id: session.storage.mock_file

in config/packages/test/framework.yaml and it worked
