I think this "orthogonal" description may not be strict enough --
as the testing effort grows exponentially.

Usually, you have tested a few sets, say a single one

   grok 0.11, ZODB 2.8.9, zope.component = 2.4.0

Now, I must integrate "grok 0.11" with a component that
requires ZODB 2.9.0 and zope.component 2.5.2.

I run the tests and can then say:

   grok 0.11 works also with "ZODB 2.9.0" and "zope.component 2.5.2".

But I do not know (without explicit testing) that

   "grok 0.11, ZODB 2.8.9, zope.component 2.5.2" is
   a working set as well.

Thus, the knowledge based on the two tests cannot be
expressed by

grok = 0.11
ZODB = 2.8.9, 2.9.0
zope.component = 2.4.0, 2.5.2
