phpunit with Netbeans on Ubuntu

As a newbie to PHP I got lots of headache on setting up phpunit. It is a little tricky to setup phpunit on Ubuntu since the documentation about this is not accurate. Make some notes here for the future references.

To install phpunit, the only way is to use PEAR. However I got annoying errors during the process.

1. apt-get does not install latest Pear, it only install the PEAR up to verision 1.9.2 which will be complained then when you are installing phpunit. Use this,

$ wget http://pear.php.net/go-pear.phar
$ php go-pear.phar

2. Then install phpunit

pear channel-discover pear.phpunit.de
pear install phpunit/PHPUnit

3. Setup netbeans for phpunit

The right path of phpunit is /home/xxx/pear/bin/phpunit not /usr/lib/php/PHPUnit as documented on neatbeans official website.
