I assume this is about COVID-19. If so, in almost 100% sure it didnt come from eating a bat.

Most recent theories are that it jumped from a bat, to a pangolin, then transferred to a human.

Edit: as for testing, I don’t think there is a test to say “yes it came from this animal”, rather you trace the disease back and look cross reference confirmed cases with animals/sources they’ve been in contact with that carry that specific virus.
