[image error] Classics never get old. Like with Shut up and Write a Test, I am reposting an old meme about lack of tests, see its preview on the right. Lack of tests is a direct result of not following the prior advice when to write tests. ;-) In many coaching discussions I need to fall back to the fundamental basics and I cannot allow such a gem to vanish. Usually I find the lack of tests in my client's code base disturbing.
