You don't even need confirmation boxes to make this better. Put the "test" options in a section all by itself, clearly labeled as test functionality. Put the real-world scary options in another section, labeled clearly, and perhaps colored red, or badged in such a way (red alert icon, or something) to indicate it's a real-world, serious action.

Yes, and designers here have a lot of power and responsibility to design an interface that is difficult to use in the wrong way, and doesn't treat options with wildly different real-world consequences as equivalent.
