For now I'm not going to remove the test asserts.

If we changes asserts in tests then it has to be by reviewing what
information the assert provides, and replacing it with something
meaningful for the test at hand. If the assert is triggering it means
some precondition of the test is being violated and that really needs to
be checked *always*.

I wonder if Arjun's scripts can help find all such asserts and possibly
do an automatic transformation (he did test-skeleton.c conversions with
a set of scripts). Arjun?

OK.

You're absolutely right. I'll adjust my commit message to mention taht.
