tye says "And I prefer to have test suites that validate the code paths so that this validation is effective before going into production, even though the checking isn't done at compile time."
This sounds like a good idea, but I'm not sure that I entirely understand it. Do you mean that you systematically exercise all of the possible paths through your program? What's a good way to actually do this in Perl?
More generally most of the modules that I've looked at have very specific tests, running a function or two from the module on defined data. This is also a good idea, and it's what I've (slavishly) copied in my own work. Could some experienced person point me ot resources on more albaorate testing of Perl software? I'm personally especially interested in database driven web sites with CGI.pm etc.
