But my documentation runs during the hourly and never raises any red flags! That means its right, therefore better than a comment. edit: You did kind of prove my point by asking for documentation outside of the test. If this "documentation" test isn't enough to find out whats really going on in my 1-line function, what makes you think a test and the best-chosen names in the world would give you any insight to a 2-line function?
