But... it adds more stars...  I don't think that there's any need for
a convenience macro that does just the combining, since that feature
is for macro writers anyway.  Here's what I have in mind:

  (sub main (printf "Welcome to MY library!\n"))
  (sub tests (require tests/eli-tester)
             (printf "Testing..."))
  (define (plus x y) (+ x y))
  (sub tests (printf ">>> ~s\n" shuffle))
  (sub main (printf "Running tests...\n")
            (require 'tests)
            (printf "Goodbye.\n"))

I have it almost working -- I just have one problem left (that last
nested require doesn't work).

(... As I wrote the above, I realized that `tests' is a better name
for this.)

In any case, I think that the above is lightweight enough that there
is no need for any `when-something'.  (I dislike specific names
because there's more than just testing.)

(And it works for the specified path(s) if given?)

How about generalizing this too?  Something like

  raco run tests <path/s>

This way, you get the others for free since `tests' is not hard
wired:

  raco run extensive-tests <path/s>
  raco run docs <path/s>
  ...
