You've been handed an old application that you're supposed to maintain and maybe extend a little bit here and there. You dig into the code and recoil in horror: No tests, sandbox modes talking to third party services, and a homegrown framework that nobody ever bothered to document? Where do you even begin? I'd like to show you some things you can do to get a grip on these problems and gain confidence in the changes you'll have to make.
