We are looking at switching from phpundercontrol to Hudson (it looks to have some really cool features!) but I can\'t figure out how to get phpunit logs to show up.
With the last answer being from 2009 and a lot of people migrating from Hudson to Jenkins now due to Oracle, consider using the Jenkins Template for PHP, offering a free and convenient template for all your configuration needs of PHPQATools, like pdepend, phpmd, phpcs and phpunit in one convenient template.
There is also the IRC channel #jenkins-php on Freenode for support.
