Mink + Driver无法连接到主机

Question

I am trying to get Mink working on Centos/Apache, but it cannot connect. I have tried with Selenium2Driver, ZombieDriver and last Sahi but I always get a different error.

Right now with Sahi:

require __DIR__ . '/vendor/autoload.php';


$driver = new \Behat\Mink\Driver\SahiDriver('firefox');
$session = new \Behat\Mink\Session($driver);

$session->start();

$session->visit('http://google.it');

echo $session->getStatusCode();

and generate this error:

Fatal error: Uncaught exception 'Buzz\Exception\RequestException' with message 'couldn't connect to host' in /var/www/html/Test/vendor/kriswallsmith/buzz/lib/Buzz/Client/Curl.php:29

I have installed with composer: behat/behat behat/mink behat/mink-sahi-driver behat/sahi-client

Why it cannot connect?
