Bootstrap of phpRack Framework

You should create a phprack.php file your public_html directory and put something similar into it:

<?php
// Global variable with params required by PhpRack bootstrap script
$phpRackConfig = array(
    // if you want to protect you phpRack installation
    'auth' => array(
        'username' => 'alex',
        'password' => 'j7L9Kj8H',
        'onlySSL' => false, // you enable connection to phpRack front only through SSL?
    ),

    // if you want to receive notifications when phpRack suite is failed
    'notify' => array(
        // email notifications
        'email' => array(
            // omit this element if you use normal sendmail
            'transport' => array(
                'class' => 'smtp', // either "smtp" or "sendmail"
                'host' => 'smtp.gmail.com',
                'port' => '25', // in case with "tls" option, can be 465, or other. Encrypted by default
                'tls' => false, // you can set this option to use TLS or SSL by default
                'username' => 'alex',
                'password' => 'j7L9Kj8H',
            ),
            // notify this email when test suite fails.
            // you can use multiple addresses. Just put them as array
            'recipients' => 'admin@example.com'
        ),
    ),
    'dir' => '../rack-tests', // where your rack tests are located, path related to the location of this file
);

// absolute path to the bootstrap script
include '../library/phpRack/bootstrap.php';

That's it.
