單元測試是幾個現代敏捷開發方法的基礎，使得PHPUnit成為許多大型PHP專案的關鍵工具。這個工具也可以被Xdebug擴充用來產生程式碼覆蓋率報告 ，並且可以與phing整合來自動測試，最後它還可以和Selenium整合來完成大型的自動化整合測試。
Windows平台LAMP環境XAMPP 1.7.3下如何安裝PHPUnit呢？
首先，以管理員身分執行cmd，使用pear新增phpunit頻道：
D:xamppphp>pear channel-discover pear.phpunit.de
Channel "pear.phpunit.de" is already initialized
Channel "pear.phpunit.de" is already initialized
頻道加好，試試安裝PHPUnit：
D:xamppphp>pear install phpunit/PHPUnit
Unknown remote channel: pear.symfony-project.com
Unknown remote channel: pear.s.com 🎜>Unknown remote channel: components.ez.no
Unknown remote channel: components.ez.no
phpunit/PHPUnit requires PEAR Installer (version >= 1.9.1), installed 7. phpunit/PHPUnit requires package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/PHPUnit can optionally use PHP extension "dbus"
Uniunphp re Installer (version >= 1.9.1), installed version is1.9.0
phpunit/DbUnit requires package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2) phpversion /File_Iterator requires PEAR Installer (version >= 1.9.1), installed version is 1.9.0
phpunit/PHP_CodeCoverage requires PEAR Installer (version >= 1.9.1), installed version 5. requires package "channel://components.ez.no/ConsoleTools" (version >= 1.6)
phpunit/PHP_CodeCoverage requires package "phpunit/File_Iterator" (version >= 1.2.2) = 2.0.5)
phpunit/PHPUnit_MockObject requires PEAR Installer (version >= 1.9.1), installed version is 1.9.0
= 1.9.1), installed version is 1.9.0
phpunit/PHP_TokenStream requires PEAR Installer (version >= 1.9.1), installed version is 1.9.0
phpunStream/PHken_Tochand .ez.no/ConsoleTools" (version >= 1.6)
No valid packages found
install failed
從提示看出，需要安裝PEAR 1.9.1，而當前PEAR是1.9.0，那就要先升級PEAR版本。
pear list-upgrades可以列出当前可用的更新，
