py-bugger 0.3.3 includes a --verbose (-v) flag. This means users don't see which file was modified unless they specifically request that information.
The goal is to replicate realistic bugs, and when new bugs appear we don't usually know which file is the problem.
I know I said I'd move on from this project, but I'm using it in an upcoming post and needed to refine the behavior a bit. And it's a fun project!
@ehmatthes Have you looked at mutation testing at all?
The idea of intentionally introducing a bug is something I sometimes explore in some of my project courses, but the main goal is to see if the bug gets picked up by testing. If not, then it exposes a testing gap of some kind.
@dabeaz I looked briefly at mutation testing libraries before writing any code, to see if there was something I could adapt instead of starting from scratch.
The bug-inducing aspects of those libraries didn't seem like they could easily be pulled out and repurposed for a library where you can specify exactly what kinds of errors you want to induce.
