I like to think about it like little minecraft characters beating on a piece of code until it works right. It's like smithing, you have to put it through it's paces and iterate as a developer, since thinking of all the complexity on large projects is infeasible. The only thing to do is to write it, test, redo it, test some more, test on a wider test bed, release, get complaints, add more tests, and finally you are at the start.
