  1. When working with older code the policy we use now is based on boy scout rules. Leave the code cleaner than you found it. So if you go work on some old code add some unit tests to the part you are working oon. if you see some really bad code take the opportunity to clean it up a little, if reasonable, and add tests for it. Take that function that is 500 lines long and break it up into many functions with a much clearer interface for each one and then test them. I have found this actually ends up working quite rapidly to fix and older code base.
