Our skipIf on the method does the same thing, because we rarely have a
setUp. Realistically, Tempest tests are often a bit strange relative to
testing you will see in project trees. Because Tempest is running tests
on real resources, computes, cinder volumes, networks which can be very
expensive to setup. This means that the bulk of the time in tempest
tests is on setup.
As a bunch of these tests aren't destructive to those resources, we
cheat a little, and build them once in setUpClass. A naive convert to
setUp would probably increase the Tempest run times by a factor of 6 to
10. We have ideas about how to do a non naive convert... but it will be
late cycle at best.
All of this is a bit of a digression, but it seemed like useful context.
