[It will not bother me if we revert this commit. I liked SK's idea and found it easy to implement. I wonder if others will be worried that it is easy to unintentionally leave off the second argument to check-error. I also wonder if it is problematic to add new string constants, like I've done.] Here is an example: (check-error (/ 1 0) "/: division by zero") (check-error (/ 1 0) "divide by zero") (check-error (/ 1 0)) (check-error 1) Here is the output: Ran 4 tests. 2 of the 4 tests failed. No signature violations. Check failures: check-error encountered the following error instead of the expected divide by zero :: /: division by zero in ex.rkt, line 2, column 0 check-error expected an error, but instead received the value 1. in ex.rkt, line 4, column 0 |
