While I tend to agree with Ben that this may not be one of
the most obvious examples for the usefulness of unit tests I
have a quite different question: I haven't gotten into the
habit of writing unit tests and actually have to admit that
I don't have much more than a rather fuzzy idea what it might
involve. On the other hand I'd rather like to learn a bit more
about this concept. Is there something you could recommend
(going a bit further than e.g. Wikipedia) for reading to get
me started (in the best of all cases not too much tied to a
single language)?
Thanks and best regards, Jens
