[Doctrine] ManyToMany Relationships not persisted in database with haveInRepository nested entity creation

Inizia da tests/functional/ManytoManyEntitiesCest.php e dalla configurazione di Doctrine2 in functional.suite.yml, quindi traccia il modo in cui haveInRepository gestisce i dati annidati di entityB. Verifica il mapping ManyToMany previsto e la sintassi dell’asserzione rispetto allo stato del database segnalato. Il lavoro è completato quando le entità sono create, la tabella di join contiene la relazione e l’asserzione finale seeInRepository ha esito positivo.

What are you trying to achieve?

I am running a functional test on a Symfony 4 + Doctrine 2 with two entities with a ManyToMany relationship. I create the entities using haveInRepository nested functionality and I expect to have the two entities created on the database and related on the join table.

What do you get instead?

The entities are created but relationships in join tables are not, so the test fails due to missing information on database.

Provide console output if related. Use -vvv mode for more details.

}

Details

With that setup, the two first seeInRepository pass but the third does not. It could be due to the syntax of the array not being correct on the last assertion as it should really be an array, but if you look into the database you can see that the join table has not been filled.

It may be due a syntax problem, but in that case it should be an issue with docs as it doesn't specify how to work with ManyToMany relationships.
