Metadata-driven lazyness, Perl, and Jenkins provide a nice mix for automated testing. With Perl the only thing required to start testing is a files path, from there the possibilities are endless. Using Symbol's qualify_to_ref makes it easy to validate @EXPORT & @EXPORT_OK, knowing the path makes it easy to use "perl -wc" to get diagnostics.

Object::Exercise replaces the pasted loops with data-driven code, the operation controlled by a data structure of methods, arguments, and expected return values. This replaces cut+paste with declarative data. This talk describes O::E and shows a few ways to apply it for testing the MadMongers' Adventure game.

Perl6 regular expression ("regex") syntax has a number of improvements over the Perl5 syntax. The inclusion of grammars as first-class entities in the language makes many uses of regexes clearer, simpler, and more maintainable. This talk looks at a few improvements in the regex syntax and also at how grammars can help make regex use cleaner and simpler.]]>
