Running migration in console command?

Question

symfony

I made my own entity generator, after generating files, 2 commands occur

/**
   * @throws Exception
   */
  private function migrateNewEntity() {
    // Generate database migration fore new Entity
    /** @var Application $application */
    $application = $this->getApplication();
    /** @var MigrationsDiffDoctrineCommand|Command $command */
    $command    = $application->find('doctrine:migrations:diff');
    $arguments  = [
      'command' => 'doctrine:migrations:diff',
    ];
    $greetInput = new ArrayInput($arguments);
    $command->run($greetInput, new NullOutput());

    // migrate new migration
    /** @var MigrationsMigrateDoctrineCommand|Command $command */
    $command    = $application->find('doctrine:migrations:migrate');
    $arguments  = [
      'command' => 'doctrine:migrations:migrate',
    ];
    $greetInput = new ArrayInput($arguments);
    $command->run($greetInput, new NullOutput());
  }

Everything falls still on the first command

In MappingException.php line 64:
                                                                                                      
  No mapping file found named 'Testik.orm.xml' for class 'App\Entity\Testik'.

Testik is the name of the entity, strange, trying to do

console doctrine:schema:validate 

Mapping
-------                                                                
 [OK] The mapping files are correct.          
Database
--------                                                                                               
 [ERROR] The database schema is not in sync with the current mapping file.

It can be seen that the files have a mapping. I manually do migrations:diff + migrations:migrate to work everything out.
Mapping files, like all others, are created before the migration starts.
Why when a command is called in another command gives an error that the file does not exist when it exists?
