Ah! Why don't they state that they shadow "error" in the documentation? Isn't that considered bad form?

It says test/exn only succeeds when the error is explicitly raised by the user, but I try something as simple as:<br> >>><br> >>> "file1.rkt"<br> >>> (provide foo)<br> >>> (define (foo) (error "hello"))<br> >>><br> >>> "file2.rkt"<br> >>> (require plai "file1.rkt")<br> >>> (test/exn (foo) "hello")<br> >>><br> >>> and the test fails with "no expected value". I can even replace "hello" with a call to error, and see that that argument is never evaluated. So by user-written code, I'm assuming they mean code contained in the same module. Or am I missing something fundamental about Racket's idea of "user-written code"?<br> >><br> >> Just a quick look, but it looks like you're failing to thunk the arguments to test/exn, so it never even gets control.<br> >><br> >> John<br> >><br> >><br> >> _________________________________________________<br> >> For list-related administrative tasks:<br> >> <a href="http://lists.racket-lang.org/listinfo/users" target="_blank">http://lists.racket-lang.org/listinfo/users</a><br> >><br> ><br> > _________________________________________________<br> > For list-related administrative tasks:<br> > <a href="http://lists.racket-lang.org/listinfo/users" target="_blank">http://lists.racket-lang.org/listinfo/users</a><br> <br> <br> <br> </div></div><font color="#888888">--<br> Jay McCarthy <<a href="mailto:jay@cs.byu.edu">jay@cs.byu.edu</a>><br> Assistant Professor / Brigham Young University<br> <a href="http://faculty.cs.byu.edu/~jay" target="_blank">http://faculty.cs.byu.edu/~jay</a><br> <br> "The glory of God is Intelligence" - D&C 93<br> </font></blockquote></div><br></div>
