[Bioperl-l] Test Suite and Test::Exception

[Chris Fields]

I always liked the Pugs smoketest system, where Pugs tests can be run  
and you get nice htmlized output, then the results can be sent to a  
smokeserver:

http://m19s28.vlinux.de/cgi-bin/pugs-smokeserv.pl?

It supposedly can be configured to test non-Pugs perl5-related stuff.
