What? No PHPUnit?

Considering half the tests in Drupal 8 are now PHPUnit based its omission from the base install is a bit of an oversight I'd think. Otherwise works great.

PHPUnit should be installed along with other composer dependencies as required per-project... how else would you like to see it installed?

Globally..
composer global require "phpunit/phpunit=4.7.*"

Also PHP Code Sniffer would be useful to have off the bat for code format compliance.

composer global require "squizlabs/php_codesniffer=*"

I ran each of these after I got it up and running, then added the composer bin directory to my path.

They're easy enough to setup though including them would further help people hit the ground running.

I've updated the upstream geerlingguy.composer role (see geerlingguy/ansible-role-composer#2), so now you can add something like the following in your config.yml file (I'll add a commented example in the project's example file in a commit in a minute or two):

composer_global_packages:
  - { name: phpunit/phpunit, release: '4.7.*' }
  - { name: phpmd/phpmd, release: '2.2.*' }
