If you haven’t already, go learn unit testing and write testable code. I promise you, your code will look much better and engineer-like. And not just the look, more importantly it reflects into your application, more robust, higher quality, SOLID. If that’s not enough, it even reflects into yourself and your career, you look more professional and not some ‘just make it work’ developers.
Good guys (and smart, of course) at Google provide easy to understand and simple to follow guide for testable code.
