Testing is really the last stage. Few software suites get there. Yes, yes, I know you're supposed to build with it in mind from day 0. And if you do that, you may never get to the finish line. You exert every ounce of energy you have to making a viable product. You worry about everything else afterward.
Nope! You should be writing your tests along with your code. Not "keep it in mind" actually write them. My first step in a new project is `mkdir spec`.
