Проблемы с настройкой PHPUnit и Selenium в PhpStorm

Я хочу запустить тест в промежуточной среде с использованием PhpStorm и перехожу по этой ссылке: https://www.sitepoint.com/using-selenium-with-phpunit/. У меня есть полные задачи до этого кода:

require_once (__DIR__.'/../../../bin/php/php5.6.25/vendor/phpunit/phpunit-selenium/PHPUnit/Extensions/');
class uatTest extends PHPUnit_Extensions_Selenium2TestCase
{
public function setUp()
{
$this->setHost('localhost');
$this->setPort(8383);
$this->setBrowserUrl('http://www.google.com/');
$this->setBrowser('firefox');
}
}

Но теперь я сталкиваюсь с этой проблемой:

C:\wamp\bin\php\php5.6.25\php.exe C:\wamp\www\phpunit-5.6.2.phar --no-configuration uatTest C:\wamp\www\PHPUnit-and-Composer-Workflow\test\uatTest.php --teamcity
Testing started at 2:10 PM ...

Process finished with exit code 255
