I’m using PHP53 package from the IUS Community repository. I’ve been trying to get phpunit to install, but it gives an error that it needs DOM install. It took me a little bit to figure this out, but I finally got it working. What you need is the php53-xml package. You can install it using

yum install php53-xml

or if you’re using puppet

package { ["php53-xml"]:
          ensure => present
        }

And finally, to get it to install, I used the below. I had to make it go to multiple lines to fit on the page but I have it all on 1 line in my puppet script:

exec { "pear channel-discover pear.phpunit.de;
pear channel-discover pear.symfony-project.com;
pear install --alldeps phpunit/PHPUnit  ":
          creates => "/usr/bin/phpunit"
 }
