Where we are
While Red Hat released Beaker as an open source project several years ago, none of the regression tests were released at that point in time.
This is now changing, with the essential installer regression tests being made available for use in Fedora as well: http://atodorov.org/blog/2013/11/19/open-source-quality-assurance-infrastructure-for-fedora-qa/
