For some test cases on my local yii framework installation I needed to install PHPUnit via PEAR in an XAMPP running on a windows system. I working in a XAMPP 1.6.7 for Windows with PHP Version 5.2.6 System. My XAMPP is installed in ?c:\development\xampp\?. Must change this for your requirements.

Installing PEAR

Execute

c:\development\xampp\php\go-pear.bat

and follow the onscreen instructions. The installation will modify the include_path in your php.ini file, so make sure that the changes are correct (and in the correct php.ini).

Execute

c:\development\xampp\php\PEAR_ENV.reg

to add PEAR to the windows registry

Installing PHPUnit

Open a command prompt

Execute

pear channel-discover pear.phpunit.de

Execute

pear install phpunit/PHPUnit

Now you should find PHPUnit installed in ?c:\development\xampp\php\PEAR\PHPUnit\? .
