The best advice I can give you is to get and read the book "Perl Testing. A Developer's Notebook" published by O'Reilly. Alternatively just google for "perl testing" and you will find lots of information about that topic.

But instead of going through the book, are there any perl cpan modules for quick reference to develop.

See TAP, especially App::prove, and likely Test::Harness.

In fact, I would suggest you make all your test output conform to the Test Anything Protocol (wikipedia), then you can use all the converters and harnesses that Perl provides for test suites.

What everyone said already. Testing in Perl is really quite easy.

# some-test.t
use strict;
use Test::More;

ok(1, "1 is okay");
is("A", "A", "A is A");
cmp_ok("B", "gt", "A", "B is greater than puny A");
isnt("A", "B", "A didn't magically become B");
like("this", qr/that/, "This is like that");

done_testing(5);

some-test.t ..
ok 1 - 1 is okay
ok 2 - A is A
ok 3 - B is greater than puny A
ok 4 - A didn't magically become B
not ok 5 - This is like that
