Hello @michael_soprano ,
To create test profiles in AEP, you should utilize a specific field group designed for this purpose. By incorporating this field group into your individual profile schema, a new attribute named testProfile will be added to your profile.
For every test profile you intend to ingest, make sure to set the testProfile attribute to true. This will enable you to effectively utilize these profiles in your customer journeys or other relevant scenarios.
You can find more detailed information at the following link: Creating Test Profiles in Adobe Experience Platform.
For differentiating the test profiles, you can always use this flag to identity if the profile is test profile or not.
Thanks,
Arpan
