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. |
