I guess that's where our opinions differ, again. I don't think it's fun to
write tests. I also don't think there's anything a new programmer "should"
be doing. He/she should be doing whatever interests them, and
learning/having fun.

Yeah, I've done the whole automated testing thing. Not my style, what can I
say? I think tests can be very valuable in the right situation, don't get me
wrong, but teaching a novice programmer about them is just confusing,
methinks.

How is a sort implementation complex? For a full-fledged, high quality sort
implementation, maybe. For a student just writing what is (probably) a
single method sort? That's going to be an exciting unit test.

I haven't given him any advice, as you so keenly pointed out. I'm sure there
are much more talented programmers who can handle that task, I'm just trying
to save a new programmer some of the confusion that's so rampant with
beginners.

Really, the point I'm trying to make is that he shouldn't be concerned with
the "real world" yet. He should try to have fun and learn at the same time,
not be bashed over the head with more complexity.
