Comment:
Hi!
It seems that there is a problem I hadn't thought of: If one has used the
spkg before, then data are accumulated that are later used when doing
related computations. Of course, I ''did'' use the package before. Now,
when testing, it can happen that the old results (potentially obtained
with an old program version) are used and spoil the tests.
So, @kcrisman, this might be another explanation for the "particularly
interesting" failure: There are old data on my computer, and I
accidentally used the old data in the tests.
I have to think how to solve that problem. Certainly the tests should work
both with and without having old data in the system. I did try to write
the tests so that the computations are either done from scratch or use
data that I have full control of, but it seems that I missed some
exceptions.
Bets regards,
Simon
