Development

The Test262 Runner script requires Perl 5.8.8, to install Perl 5.8.8, use Perlbrew.

It’s not necessary to install Perl 5.8.8 to execute the runner script if you have a more recent version of Perl 5.x.x installed.

It's also not necessary to install or configure anything extra to execute the runner script. The script dependencies are also stored locally.

Installing Perlbrew

Mac

\curl -L https://install.perlbrew.pl | bash

Linux (Debian derivative):

sudo apt-get install perlbrew
perlbrew init

Loading Perlbrew

Append the following piece of code to the end of your ~/.bash_profile and start a new shell, perlbrew should be up and fully functional from there:

source ~/perl5/perlbrew/etc/bashrc

Installing Perl 5.8.8 through Perlbrew

Mac

perlbrew install perl-5.8.8

Linux

perlbrew --notest install perl-5.8.8 # Perl 5.8.8 has some known compilation errors

Switching to Perl versions

perlbrew switch perl-5.8.8
perlbrew switch perl-5.27.6
# ...

Install cpanminus and Carton

Install cpanminus and Carton to set and manage dependencies.

perlbrew install-cpanm
cpanm install Carton

Installing dependencies through Carton

From the Tools/Scripts/test262-helpes/ folder, run carton install to install dependencies from the cpanfile.

More documentation on the cpanfile here.

Executing the script using Carton:

carton exec runner.pl

Loading dependencies without Carton

To run the script without Carton, prepend your script file with the following code:

use FindBin;
use Config;
use Encode;

BEGIN {
    $ENV{DBIC_OVERWRITE_HELPER_METHODS_OK} = 1;

    unshift @INC, ".";
    unshift @INC, "$FindBin::Bin/lib";
    unshift @INC, "$FindBin::Bin/local/lib/perl5";
    unshift @INC, "$FindBin::Bin/local/lib/perl5/$Config{archname}";

    $ENV{LOAD_ROUTES} = 1;
}
