Heya monks,

How do we create a testing for a stand alone application (i.e. not a module)?

Test::Tutorial explains that we could create a *.t file for each *.pm module, but if what I have is only a single *.pl file, how do I create the *.t file?
I mean, I can write a *.t file that tests every case in the application, but if someone changes something in the *.pl file, then my *.t file will never catch the modification?

For example if I have a skeleton script as below in my foo.pl, could someone please shed a light with the test suite? 
#!/usr/bin/perl

use strict;
use warnings;

main();
exit 0;

sub main {
  my @files = get_xml_files();
  extract_file(\@files);
}

sub get_xml_files {
  my @files = glob(*.xml);
  return @files;
}

sub extract_file {
  my ($file) = @_;
  # Do something...
  return;
}
