If you have to maintain tests written by other devs you might start to care. Devs apply different patterns to writing tests and show different amounts of discipline doing so. Some produce lots of duplication ("it doesn't matter, it's just a unit test"), others prefer a complete setup and tear-down before and after every little assertion. I've seen things..

I've seen unit tests that test around bugs. Once you fix the bug, a lot of tests fail. Then you discover there is no easy fix for the test. Either delete them all or replace them with new ones.
