IPC::Run looks quite nice and easy. It looks like the timeout from the module handles alarm-style behavior.

Actually, IPC::Run looked so nice and easy that I tried it out. My attempts to use it pleased me, so I wrote a little wrapper to hide some of the clutter.

package Test::CLI; use Modern::Perl; use IPC::Run qw(run timeout); use Test::More; use base qw(Exporter); our @EXPORT_OK = qw( run_output_is ); our $TIMEOUT = 10; sub run_output_is { my ($expected, $command, $input, $diagnostic) = @_; my ($out, $err); run $command, \$input, \$out, \$err, timeout($TIMEOUT); is $expected, $out, $diagnostic; } 1;

That allowed for a nice simple script in my test code.

use Modern::Perl; use Test::CLI qw(run_output_is); use Test::More tests => 1; my @command = qw(parrot code/example-01-06.pir); my $in =<<INPUT Brian INPUT ; my $expected =<<EXPECTED Please enter your name: Brian Hello, Brian! EXPECTED ; run_output_is $expected, \@command, $in;

So thanks for the suggestion! That worked quite nicely for my needs.

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.
