Php yii框架中的include_路径定义在哪里？

问题：在哪里定义包含路径？ 我尝试运行PhpUnit测试。将cd复制到项目文件夹并使用命令： “phpunit/functional/SiteTest.php”。命令行输出：

c:\xampp\htdocs\yii\projects\demo\protected\tests>phpunit  functional/SiteTest.php

Warning: require_once(PHPUnit/Extensions/SeleniumTestCase.php): failed 

to open stream: No such file or directory in C:\xampp\htdocs\yii\framework\test\CWebTestCase.php on line 12

Fatal error: require_once(): Failed opening required 

'PHPUnit/Extensions/SeleniumTestCase.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs

\yii\framework\test\CWebTestCase.php on line 12

在哪里定义了include_路径？我需要更改include目录，在我的示例中是c:xampp\php，而不是c:\xampp\php\PEAR

config/main.php的内容：

我去了：[
下载：PHPUnit_Selenium 1.3.3
未开发和未驯服
已从内部文件夹复制内容
'C:\Users\Gintare\Downloads\PHPUnit\u Selenium-1.3.3\PHPUnit\u Selenium-1.3.3\PHPUnit\u Selenium-1.3.3\PHPUnit\Extensions\'
到文件夹
c:\xampp\php\PhpUnit\Extensions.

PHPUnit测试开始工作。
config/main.php中未定义包含路径
