Running pytest fails due to path issues: No such file or directory: 'generated_data/ed25519_metadata' #2745
Description
Hi! I'm working on packaging of Python-TUF for Debian and ran into this self-check failure which I can reproduce in a basic git checkout of d805a81 which is master per 2024-12-06.
Shouldn't running 'pytest' work automatically? Is there some path confusion here, or why does this fail?
