2 hours spent writing a custom #Django migration for a huge model refactor
8 hours spent writing tests for it (albeit the project didn't have any proper testing setup in place)

And oh my God, it was worth it, since I have already found two bugs I would've just miss otherwise. Learning a lot along the way, too: #pytest, #faker, #FactoryBoy. So exciting 🤩 I think I definitely picked the right career path 😅
