This is the second post in the How To Ask a Question (With Test::More) series, and assumes you have read the first, main post.

In this installment, we learn how to use Test::More::like($string, $regex) and the qr quotelike operator to ask regex questions in a sane way. Let's dive right in.

******************BEGIN QUESTION TEMPLATE************************

O Wise Monks, I can't get this regex to do what I want it to do. As you can see, it fails two tests.

use warnings; use strict; use Test::More qw(no_plan); my $emailsregex = qr/\w+@\w+\.(net|com|org)/; while (<DATA>) { like($_, $emailsregex) } __DATA__ timmytimmers@aol.com hillary-hillers@aol.com garbygerbil@herbill.gerbil.org garbygerbil@herbill.gorgil.org reginald_reggers@aol.com
I'm on Windows XP system using the standard ActiveState perl distribution.

I got both standard and error output out of my test, into one output file, by running this with emailsregex.pl > output.txt 2>&1 output.txt.

The output I got was

ok 1 ok 2 not ok 3 # Failed test (emailsregex.pl at line 8) # 'garbygerbil@herbill.gerbil.org # ' # doesn't match '(?-xism:\w+@\w+\.(net|com|org))' not ok 4 # Failed test (emailsregex.pl at line 8) # 'garbygerbil@herbill.gorgil.org # ' # doesn't match '(?-xism:\w+@\w+\.(net|com|org))' ok 5 1..5 # Looks like you failed 2 tests of 5.

What the heck am I doing wrong?

******************END QUESTION TEMPLATE************************

(Debugging the regex is left as an exercise for the reader.)
