Well well well.
Well well well.
Seriously, once you commited something to the repo it’s hard to lose it. Unless you delete .git. But a this point frequent pushing has your back.
I know git can be hard to grasp in the beginning. It was hard for me to. I highly encourage everyone to put in the effort to understand it. But if you don’t want to do that right now just use it. Just commit and push. It will pay off.
Ah, the classical “just introduce tests in a legacy codebase”, what can go wrong?
My condolences, it’s always a BITCH to handle
