Testing is an often overlooked yet critical component of any software system. In some ways this is more true of models than traditional software. The reason is that computational systems must function correctly at both the system level and the model level. This article provides some guidelines and tips to increase the certainty around the correctness of your models. One of my mantras is that a good tool extends our ability and never gets in our way. I avoid many libraries and applications because the tool gets in my way more than it helps me.
