It's a choice of course, but I look at test functions like other functions. If you can name a function such that it doesn't need a comment (but also doesn't use 100 characters to do that), I'll gladly take that over a comment. Same like in all other code: if you need comments to explain what it does, it's likely not good enough and/or needs to be put in a function which tells what it does. Comments on why it does stuff the way it does are of course where it's at.
