They can do payment testing, but they can't do trading. If you are a stock exchange app, you can't do trading. Obviously, there are limitations related to GDPR, etc, but that is one thing for which they can find solutions. I'd like to see how effectively they can do trading on the app, which is something they are not covering right now. So, the testers currently can't do trading. If you're buying stock and your app allows you to buy Microsoft and Google shares, that is something that is currently not in the testing purview. So, that is something that I would like them to include.
