Go to the directory where PHP is located. Typically, this is <PATH-TO-YOUR-WAMP-INSTALLATION>\bin\php\php5.3.8
We’ll call this path “PHP’s location” throughout this article.
Now, install PEAR following instructions in this tutorial.
Open a command-prompt, go to PHP’s location using cd, and type:
pear channel-discover components.ez.no pear channel-discover pear.phpunit.de pear channel-discover pear.symfony-project.com pear install --alldeps phpunit/PHPUnit
We’re done! type phpunit –version to confirm installation.
