( #3333=superdoc: print w/ replies, xml ) Need Help??

I've been a long-term user of test cases for my own code, as that gives me confidence that my code is good - or at the very least that changes I introduce haven't broken things too much!

My test-cases, in general, have been fairly straightforward in nature, and have worked without issues. As a matter of course I try to document the requirements of my code via a test case modules.t, which should ensure that anybody who can make the test case run successfully (via "make test") has all the modules required.

Here is an explicit example:

#!/usr/bin/perl -w -I.. # # Test that all the Perl modules we require are available. # (This list is automatically generated.) use Test::More qw( no_plan ); # ... BEGIN{ use_ok( 'CGI' ); } require_ok( 'CGI' ); BEGIN{ use_ok( 'Date::Format' ); } require_ok( 'Date::Format' ); BEGIN{ use_ok( 'POSIX' ); } require_ok( 'POSIX' ); # ... # ...

This test is part of a series which runs, via cron, on a daily basis. Unfortunately the combination of modules which I'm testing for give me a whole bunch of spam on STDERR:

skx@gold:~$ perl t.t > /dev/null Subroutine main::ctime redefined at (eval 4) line 2 Prototype mismatch: sub main::ctime ($;$) vs none at (eval 4) line 2 Subroutine main::strftime redefined at (eval 4) line 2 Prototype mismatch: sub main::strftime ($\@;$) vs none at (eval 4) lin +e 2 Subroutine main::asctime redefined at (eval 4) line 2 Prototype mismatch: sub main::asctime (\@;$) vs none at (eval 4) line +2

So, my question. Is it possible for me to avoid these errors whilst still working in the "standard" way when it comes to using Test::More and testing module availability?

(Certainly I accept that making my crontab entry throw away STDERR would solve my immediate problem, but it might hide things from me in the future.)
