Actually, there is a *ton* of obsolete information on that page:
there's no serial_schedule file anymore, and we don't have
dynamically-generated test files anymore (input/output subdirectories)
and therefore there's no substituted variables. The age of the whole
thing can be dated by its references to CVS :-(
Maybe we should indeed try to replace it with something in the main
docs, which are a bit more likely to get maintained. There is an
existing chapter "Regression Tests", but it presently only talks
about how to run the tests not how to write new ones.
