Are you sure the usage of $iterator->current() targeting TheCodingMachine\TDBM\EmptyInnerResultIterator::current() seems to always return null.

        $this->assertNull($iterator->key());

Are you sure the usage of $iterator->key() targeting TheCodingMachine\TDBM\EmptyInnerResultIterator::key() seems to always return null.
