          Please avoid 'rand' if possible. It does not guarantee uniqueness which means that there is a risk of collisions. Possible alternatives:
          - If you need unique values, consider using 'SecureRandom.uuid'.
          - To randomly select a value from a list, use [].sample.
          - To generate random test data that does not need to be unique, you can use 'Faker::*'.
