在ZF2中PHp单元测试错误'Undefined index: SERVER_NAME in /config/autoload/global.php'

I've just started with Zend framework 2. I want to set up unit testing for my Cart module.

I have followed the steps of http://framework.zend.com/manual/current/en/tutorials/unittesting.html

When I run :/var/www/AHA/CDP/module/Cart/tests$ phpunit from terminal I am getting following output:

Sebastian Bergmann的PHPUnit 3.7.28 .

配置从/var/www/ZF2Sample/module/Cart/tests/phpunit.xml中读取

FAILURES！测试：1，断言：0，错误：1 .

Below is my global.php :

<?php
    define('SITE_URL', 'http://' . $_SERVER['SERVER_NAME'].'/');
    define('JS_URL', 'http://' . $_SERVER['SERVER_NAME'].'/js/');
    define('CSS_URL', 'http://' . $_SERVER['SERVER_NAME'].'/css/');
    define('IMG_URL', 'http://' . $_SERVER['SERVER_NAME'].'/img/');
    return array(
        'cart_webservice_url' => "http://" . $_SERVER['SERVER_NAME'] . "/ecommercewebservices",
    );
?>

I placed $_SERVER['SERVER_NAME'] = 'myproject.com'; at beginning of global.php

Then I got below output :

I searched a lot but could not find any answer . Please suggest.
