Today I installed PHPUnit Skeleton Generator like this:

 $ vim ~/.composer/composer.json

Added:

 "minimum-stability": "dev"

 $ composer global require 'phpunit/phpunit-skeleton-generator=*'

But… then it turned out that the interface was broken when invoking from NetBeans, so over here:

$ pear channel-discover components.ez.no
$ pear install phpunit/PHPUnit_SkeletonGenerator

Then I created a phpunit-skelgen.php file in my project and added:

#!/usr/bin/php
<?php

require_once '/usr/share/php/SebastianBergmann/PHPUnit/SkeletonGenerator/autoload.php';
require_once '/usr/share/php/SebastianBergmann/PHPUnit/SkeletonGenerator/Command.php';

SebastianBergmann\PHPUnit\SkeletonGenerator\Command::main();

Simple! :)
