I'd separate out the testing from the program. It makes your code cleaner, and you won't pay the costs of compiling your test suite each time you run the program.
# Main program: #!/usr/bin/perl use strict; use warnings; sub double { my $n = shift; return $n * 2; } return 1 if caller; # Don't leave this out. print join ' ', map {double($_)} @ARGV; print "\n"; __END__ # Test program: #!/usr/bin/perl use strict; use warnings; use Test::Simple tests => 3; require 'main.pl'; # Substitute the name of your program. ok(double( 2) == 4); ok(double(-3) == -6); ok(double( 0) == 0); __END__

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
