in reply to Application Testing: Custom Module or Perl Test Files?

You may also wish to check out Test::WWW::Mechanize, which automates some parts of testing sites. I've had good success with subclassing Test::Unit and writing a custom method for each feature I want to test, with a Test::WWW:Mechanize instance created in set_up() or new(). I know that Test::Unit is largely deprecated in favour of Test::Class, but it's a useful module.
