I've been setting up a local dev environment and when running the tests I receive the following errors:
root@:~/sites/drupal8# sudo -u www-data php core/scripts/run-tests.sh --url http://drupal8.doggz/ --concurrency 8 --all > ../test-output.txt
PHP Fatal error: Class 'Drupal\system\Tests\Form\CallbackBuilderTest' not found in /home/ben/sites/drupal8/core/scripts/run-tests.sh on line 402
