It seems like you are calling the size function count() as part of the test condition. You might want to compute the size beforehand, and not on each iteration.

            $questionAsArray['answers'][$index]['id'] = $this->uuidFactory->uuid4()->toString();
        }

        return json_encode($questionAsArray);
    }
