Prophecy not supported returning by reference ORM 2.6

[mayro]

Hello,
I use Prophecy to testing my code. I have this code in my test class

$unitOfWork = $this->prophesize(UnitOfWork::class);
$unitOfWork->getEntityChangeSet(Argument::exact($account))->willReturn($changeSet)->shouldBeCalled();

With Doctrine/Orm V2.6, so my test doesn't pass anymore, with return by reference in getEntityChangeSet Prophecy\Exception\Doubler\ReturnByReferenceException: Returning by reference not supported

Have you any suggestion to testing my class with Prophecy?

Thanks.

That's not possible with Prophecy.
I really don't know the reasons of this behaviour but I suppose is due to "double" encapsulation and those kind of things.

If you would like to test a class that relies on third party code you should not use Prophecy (more in general you should not do unit tests) at all: do other kind of test (functional, e2e, integration, etc)

I suggest you read this http://docs.park-manager.com/en/latest/contributing/code/testing.html#don-t-mock-a-type-you-don-t-own 👍
