Maybe, but you still need to maintain the list of files somewhere. And
in any case it doesn't change the fact that the number of files must be
kept small. If the test program is not clever enough to manage large
files it should be fixed.

No, that's just noise. Simply output the description instead of
outputting a random id and hiding the description in a comment.
