Is there a way to perform A/B testing in AEM instead of picking the QA activity URLs from Adobe Target and testing it.
i was hoping it can all be done within AEM, looking at experiences and testing it within AEM
Contexthub in AEM does not allow A/B testing. Target is required for A/B testing. Check  for more details.
Within AEM, you can use the targeting mode, but data will be fetched from Target.
