Installing PHPUnit on Ubuntu with Composer

I foolishly installed PHPUnit on Ubuntu 12.04 using PEAR.

sudo apt-get install php-pear
sudo pear channel-discover pear.phpunit.de
sudo pear install --alldeps phpunit/PHPUnit

When I went to run it I recieved this message:
You have installed PHPUnit via PEAR. This installation method is no longer
supported and http://pear.phpunit.de/ will be shut down no later than
December, 31 2014.
Please read http://phpunit.de/manual/current/en/installation.html and
learn how to use PHPUnit from a PHAR or install it via Composer.

So first let's remove phpunit and send PEAR away for good

$ sudo apt-get remove phpunit
$ sudo apt-get remove php-pear

Then, assuming Composer is already installed
<br />
$ curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin<br />
$ ln -s /usr/local/bin/composer.phar /usr/local/bin/composer<br />

$ composer global require "phpunit/phpunit=4.1.*"
$ composer global require "phpunit/php-invoker=~1.1."

next, find the ".composer" directory, mine was in my home directory, and create a symbolic link so we can call it from the command line like so: $phpunit

$ sudo ln -s  ~/.composer/vendor/phpunit/phpunit/phpunit   /usr/bin/

Voila!

Unit test your app and say goodbye to PEAR forever (lol).

$ phpunit -c app/
