"This is true even when simple test runners are used, but I decided to make things a little snappier by including a couple of other types of measurement and generating a "scorecard" for the present state and progress of my Python software projects. Here's how it works, and a download link for my script, which I call "PyRate".

"Programming is one of the most extreme examples of delayed gratification — you can work for months without having anything to show for it (or at least nothing that would convince your family that it was worth all that time and trouble). This can be really demoralizing, especially if you have any doubts about your abilities to begin with.

"Testing helps. You won't be able to convince many other people of your progress, but at least you will have an objective measure telling you how much closer to your goal you are every day you work on the project. Also, because automated testing catches bugs right when they happen, it's usually much easier to track them down (because you know what you've changed since the previous test)."
