Zenzizenzizenzic has asked for the wisdom of the Perl Monks concerning the following question:

Have been working in Perl at my current job for about 3 years. We have currently no in place testing of any sort for the perl code. What I've seen seems to require all the parts to be tested to be in modules. 80% of the code base is in .pl files only. Is there any (easy, hopefully) way to be able to test this code without re-writes?
