Test if you can, but I agree. Thinking unit testing will solve the problem can be incredibly naive especially if the code has lots of global state. Sometimes, just setting up all this state for a test is equivalent to rewriting the application. If the rest of the application is written like this, chances are this function makes a ton of 2k line calls of its own. Unit testing just might make sure you aren't doing something catastrophically dumb.
