Research direction
Start by reproducing the two examples in the issue and locating the implementation of test(), then trace how it handles uncaught warnings and messages. Done means uncaught cat() output causes an error while the existing warning and message checks continue to behave as shown.
Written by the indexing model from the issue text.
Description
test(1, { cat("123\n"); TRUE })
# 123
That should error IMO, much as we error for uncaught warnings/messages:
test(1, { message("123\n"); TRUE })
Test 1 produced 1 messages but expected 0
Expected:
Observed: 123
This will help keep the test log clean and is also a best practice IMO.
