[R] Checking for a proper "stop" statement...

Consider the following two use cases:
goodfunction <- function()
stop("Something went wrong..."
badfunction <- function()
Is there a way for me to test if the functions make use of a stop()
statement WITHOUT modifying the stop() output (assume I can't mod the
function containing the stop() statement itself)? For "goodfunction" the
answer is TRUE, for "badfunction" the answer is FALSE. Both return an
error, but only one does it "safely".
I thought the answer might lie in a tryCatch statement but I'm having a
hard time figuring out how to do this test.
