Writing unit tests which encode the developer's assumptions about what
the real world looks like is som much easier than verifying that
unit-tested code actually works with existing, persistent data "in the
wild."

Changing TypeInformation is scary, because getting it wrong takes your
CMF site down completely until you repair the damage.  Dieter and Yuppie
pointed out to me that the conversion code was already in place;  I
added a test for it the day before yesterday, *and* have verified that
an "old" CMF site comes up cleanly against it.
