I'd like to write a unit test that a syntax-parse expectation failure elicits a certain error message. For instance, I'd do a regexp-match? that "something" is present in a message like "expected something".
However it seems that syntax-parse expectation failures don't raise an exception. In other words, this will never return 'caught: (with-handlers ([exn? (lambda (exn) 'caught)]) something-that-elicits-a-syntax-parse-expectation-failure) (At first I'd tried exn:syntax?, and when that didn't work, I checked to see if it was any kind of exception. Seems not.) Is there another way to go about this? p.s. Having such a unit test would be a nice-to-have, not must-have. So if this can't be done, that's fine. I just wanted to double-check if there's some way. ____________________ Racket Users list: http://lists.racket-lang.org/users
