Hi Kevin. Welcome to the most awesome software quality community in the milky way. (not a verifiable fact) But it’s still the right place to be, glad you are here now, with a good question, that has perhaps been asked before in another fashion.
Hmmm what if we invert your question:
What if we word it like - I have an A/B test? or perhaps we phrase it as the product has multiple license tiers, or even as the product has multiple security groups, which tests do I run? If you do currently limit your tests to run in only specific scenarios, then you probably want to just keep on doing the same thing, write a custom test for each feature combination you care about. I prefer a more META approach and table-driven tests to solve this as it tends to scale better. But that’s just my opinion, why no read what the community thought when this question was asked 3 years ago. 30 Days of DevOps Day 25: Feature Flags
