Perl.com Publishes an Introduction to Software Testing in Perl
Perl.com published an article by chromatic introducing software engineering testing methodology and the Perl testing tools that can be used to implement it. This is a valuable article, but is best understood when it is looked at side-by-side with an uninstalled Perl module.
For an idea of just how rigorously code can be tested in an automated fashion, take a look at Perl module test output. The output is even more impressive with the verbose option turned on. Isn't it sad that so many Perl modules have such rigorous verification methods, while so many corporate Perl projects don't even use strict?
