Different results if I run one test and all test in same time

Riproduci il problema eseguendo i comandi dei test funzionali Codeception per un singolo file e per un'intera directory mostrati nel report. Leggi i metodi _before() dei Cest e la configurazione di ZF2, Doctrine2, DataFactory e della pulizia. Il lavoro è completato quando gli stessi test producono risultati coerenti se eseguiti singolarmente o come suite.

What are you trying to achieve?

Right now, I have some strange behaviour while running functional tests. If I run one file codecept run functional /FunctionalFolder/Services/ServiceOneCest, all tests are success - as expected. But in secound case, when I run all created tests codecept run functional /FunctionalFolder, some tests are finished as expected, while some others are failed.

Somehow, in _before() section, are not executed all dependeces.

class ServiceOneCest
{
public function _before(FunctionalTester $I)
 {
            $this->entityManager = $I->grabServiceFromContainer(EntityManager::class);
            $this->entity = $this->entityManager->getRepository(Entity::class)
            ->findOneBy([
                'name' => 'test'
            ]);
         
        if (!$this->entity) {
            $this->entity = $I->have(Entity::class, ['name' => 'test']);
        }
}

public function testSomething(FunctionalTester $I)
{
      $I->assertEquals('test', $this->entity->getName());
      // here I catch error message [Error] Call to a member function getName() on null
      // it only happend when I run more then one test file
}
}

//also exist some other test file

class ServiceTwoCest
{
}

I expect same results if I run one test file or more. I need to say, don't have any dependece between test data created in _before()

Please, if you see any reason or my bad code/configuration anything, give me handsup. If you have some other questions, please feel free to contact me.
