There is actually, but only for python2.6 unittests run on CentOS 6.5.
All of the tempest tests run on Ubuntu Precise with most jobs using
MySQL and a few using PostgreSQL. None of the tests use MariaDB today.
There were folks working on getting Fedora nodes into nodepool to do
testing of some sort on Fedora (which would be MariaDB aiui), but ran
into trouble around nodepool's privilege expectations (something about
sudo needing a proper tty and paramiko not being able to nicely provide
one). We should pick that work back up again, but Infra has been swamped

If we do end up adding MariaDB integration (tempest) tests I would not
add another set of tests. Instead we should probably swap out MySQL and
use MariaDB in one of the existing tests.
