Actually line numbers are not logged by messages printed from "make test", so moving code around does not break the test.

Changing what programs output does break the test and this is intentional - somebody must look at confirm
that program output was changed on purpose or because a bug was introduced (or fixed).

Most "make test" things work this way - run programs, compare output to what is expected. Discrepancies are flagged for human examination.
