Generally when given this scenario, I have used Test::MockModule to override something like Data::Record->records() in your example with results that would fully exercise the code, regardless of whether it would otherwise be triggered in its 'natural state'.

Correct me if I'm wrong, but that's a generally acceptable testing practice, isn't it?

perl -e 'split//,q{john hurl, pest caretaker}and(map{print @_[$_]}(joi
+n(q{},map{sprintf(qq{%010u},$_)}(2**2*307*4993,5*101*641*5261,7*59*79
+*36997,13*17*71*45131,3**2*67*89*167*181))=~/\d{2}/g));'
