[racket] Can `raco test ...' return non 0 values?

raco test's job is to run the 'test' modules of the programs listed.
It imposes no obligations on what these test modules do and does not
communicate with them in any way. Thus, it has no concept of "a check
failing".

If you want, you can write your test modules so that they exit with
non-0 when they fail, which raco test will pass on to you:

(module+ test
 (unless (= 0 (f 5))
  (error 'test-failure "F of 5 is not 0!")))

If this is your test module, then raco test will return a non-0
because 'error' returns a non-0.

There's a good reason that 'rackunit' doesn't work this way, but if
you disagree with that design, you could use a different testing
system and 'raco test' would respect it.
