Unit testing is the foundation of several modern agile development methodologies, making PHPUnit a key tool for many large PHP projects. This tool can also be used by the Xdebug extension to generate code coverage reports, and can be integrated with phing to automate testing. Finally, it can be integrated with Selenium to complete large-scale automated integration testing.
How to install PHPUnit under XAMPP 1.7.3 in Windows platform LAMP environment?
First, run cmd as administrator and use pear to add phpunit channel:
D:xamppphp>pear channel-discover pear.phpunit.de
Channel "pear.phpunit.de" is already initialized
After the channel is added, try to install PHPUnit :
D:xamppphp>pear install phpunit/PHPUnit
Unknown remote channel: pear.symfony-project.com
Unknown remote channel: pear.symfony-project.com
Unknown remote channel: components.ez.no
Unknown remote channel: components.ez.no
phpunit/PHPUnit requires PEAR Installer (version >= 1.9.1), installed version is 1.9.0
phpunit/PHPUnit requires package "channel://pear.symfony-project.com/YAML" ( version >= 1.0.2)
phpunit/PHPUnit can optionally use PHP extension "dbus"
phpunit/DbUnit requires PEAR Installer (version >= 1.9.1), installed version is1.9.0
phpunit/DbUnit requires package "channel ://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/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 is 1.9.0
phpunit/PHP_CodeCoverage requires package "channel://components.ez.no/ConsoleTools" (version >= 1.6)
phpunit/PHP_CodeCoverage requires package "phpunit/File_Iterator" (version >= 1.2.2)
phpunit/PHP_CodeCoverage can optionally use PHP extension "xdebug" (version >= 2.0.5)
phpunit/PHPUnit_MockObject requires PEAR Installer (version >= 1.9.1 ), installed version is 1.9.0
phpunit/PHPUnit_Selenium requires PEAR Installer (version >= 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
phpunit/PHP_TokenStream requires package "channel://components.ez.no/ConsoleTools" (version >= 1.6)
No valid packages found
install failed
It can be seen from the prompt that PEAR 1.9.1 needs to be installed , and the current PEAR is 1.9.0, then you need to upgrade the PEAR version first.

更新成功后，PEAR已经是1.9.1版了，现在可以放心地安装PHPUnit了：

上面信息来看，还是没有安装成功，pear.symfony-project.com和components.ez.no两个频道也要添加一下：
D:xamppphp>pear channel-discover pear.symfony-project.com
Adding Channel "pear.symfony-project.com" succeeded
Discovery of channel "pear.symfony-project.com" succeeded
D:xamppphp>pear channel-discover components.ez.no

再次尝试安装PHPUnit：
D:xamppphp>pear install phpunit/PHPUnit
phpunit/PHPUnit can optionally use PHP extension "dbus"
phpunit/PHP_CodeCoverage can optionally use PHP extension "xdebug" (version >= 2.0.5)
