Creating a custom generator

You can create custom generators in addition to the existing generators in the HCL DevOps Test Hub (Test Hub) catalog. You can customize the existing generators and save them as new custom generators to help you create complex real-world scenarios for synthetic data generation. Additionally, custom generators enable the generation of data for specialized fields or domains that may not be readily available in standard datasets.
