在安装之前，需要配置好PHPUnit的开发环境。在PHPUnit的新版本已经迁移到自己的pear.phpunit.de网站上了。本文假设你已经配置好Xampp的开发环境，我之前的文章PHP开发环境的搭建。
首先升级你的pear版本，新PHPUnit 3.6 要求PEAR的版本较高。在开始菜单打开CMD命令行。
cd /d D:xamppphp pear config-show CONFIGURATION (CHANNEL PEAR.PHP.NET): ===================================== Auto-discover new Channels auto_discover 1 Default Channel default_channel pear.php.net HTTP Proxy Server Address http_proxy <not set> PEAR server [DEPRECATED] master_server pear.php.net Default Channel Mirror preferred_mirror pear.php.net Remote Configuration File remote_config <not set> PEAR executables directory bin_dir D:xamppphp PEAR documentation directory doc_dir D:xamppphpdocs PHP extension directory ext_dir D:xamppphpext PEAR directory php_dir D:xamppphppear PEAR Installer cache directory cache_dir D:xamppphp mp PEAR configuration file cfg_dir D:xamppphpcfg directory PEAR data directory data_dir D:xamppphpdata PEAR Installer download download_dir D:xamppphp mp directory PHP CLI/CGI binary php_bin D:xamppphp.php.exe php.ini location php_ini <not set> --program-prefix passed to php_prefix <not set> PHP's ./configure --program-suffix passed to php_suffix <not set> PHP's ./configure PEAR Installer temp directory temp_dir D:xamppphp mp PEAR test directory test_dir D:xamppphp ests PEAR www files directory www_dir D:xamppphpwww Cache TimeToLive cache_ttl 3600 Preferred Package State preferred_state stable Unix file mask umask 0 Debug Log Level verbose 1 PEAR password (for password <not set> maintainers) Signature Handling Program sig_bin c:gnupggpg.exe Signature Key Directory sig_keydir C:Windowspearkeys Signature Key Id sig_keyid <not set> Package Signature Type sig_type gpg PEAR username (for username <not set> maintainers) User Configuration File Filename C:Windowspear.ini System Configuration File Filename C:Windowspearsys.ini
以上是我的pear配置文件，仅供参考，输入以下命令升级pear的版本
