Bug Report

Summary

The method Doctrine\ODM\MongoDB\Aggregation\Builder::execute() is deprecated and should be replaced by $builder->getAggregation()->getIterator() (Note that it's more verbose for the common use case).

But getAggregation() must return an instance of Doctrine\ODM\MongoDB\Aggregation\Aggregation. This class is hard to instantiate in tests as it requires a lot of dependencies that would have to be mocked with the ODM internal behavior. Since the class is final, it cannot be mocked.

I created a draft PR to remove usage of Aggregation\Builder::execute() in API Platform, but the tests cannot be fixed. GromNaN/api-platform-core#2

The solutions would be to remove the final keyword on Doctrine\ODM\MongoDB\Aggregation\Aggregation.
