"You upload a build of your app without providing any additional instructions, and we'll test your app from a user's perspective..."

It seems like a user should have at least some idea of what the app is. For example, I'll read the first couple sentences of an app's description and look at some screenshots/video before I decide to download it. This might be something you want to consider instead of having absolutely no idea what the app is before running it, since I assume most users have at least some context when opening an app.

It's usually a good idea when user testing to tell testers as little as possible about the product. It's true that real-world users have more context than that, but it can be worth it to get more unfiltered feedback— the first few moments you watch a user flounder to even understand what they're looking at can be the most valuable.

Good point! There is an option to attach additional information (description, notes, link to website/app store) when uploading an individual build. We do ask for a little bit of information about the app in general when the first build is uploaded so that we have some context.
