Testing persisted entities within Phpunit

Question

I'd like to assert that a method creates and persists certain entities. The method's class has an instance of EntityManagerInterface injected into it.

Within my Phpunit test I can do:

    $mockEntityManager = $this->getMockBuilder(EntityManagerInterface::class)
        ->disableOriginalConstructor()
        ->getMock();

and then instantiate the class and execute the method. However how can I check what entities get persisted?

Ideally I would just be able to override $mockEntityManager's persist method with some arbitrary closure, e.g. one which appends to some $expectedPersistedEntities array, then I can make assertions against this array. However it seems overriding methods with custom behaviour is not possible in PHP.

If it was only one object being persisted then I could do e.g.

        $mockEntityManager->expects(self::once())
            ->method('persist')
            ->with($expectedSyncedObject);

however I'm expecting multiple different objects to get persisted and would like to assert all of them do so.

Is this possible?

You can check every instance being persisted using withConsecutive see the doc
