Comment (by osa1):

 I'm going over cost-center-related tickets -- does anyone know how do I
 test and close this? As far as I can see `.prof.sample` files are not good
 enough for testing purposes. For example, I created a `.prof.sample` for
 testing this, but if I remove a random line in that file the test is still
 accepted. What am I doing wrong?
