Thank you Gary, great explanation. Here is some notes from me, maybe for someone it will be useful:
1. it's not necessary to define the name of the event, the class name is enough: AfterDtoCreatedEvent::class => 'validateDto'
2. in your test the container also not necessary, you can create dispatcher by handle, so it will be like below:
$dispatcher = new EventDispatcher();
$event = new AfterDtoCreatedEvent($dto);
$subscriber = new DtoSubscriber($validator);

//your expectation checks here

Hi Gary I don't understand the Philosophie why you used the events and not just using validation without events subscribers....

Thank you, that was a good explanation, and what's more important, done on the newest version of Symfony :)
