Is it possible to specify that certain tables not be cleared on each

I've inherited a project where a good amount of enumerated data is
stored in the database (US States, statuses, about 15-20 tables
worth. Over all, it's a reasonable decision that leads to solid
production code (acts_as_enumerated is good). This data is read-only
and relatively static; any changes to these tables are done via
migrations.
The problem comes when I'm writing my tests. Obviously all these
tables get wiped with each example.
This should not be the case. Transactions get rolled back, but tables
do not just get wiped clean.
If this static data is being generated in migrations, then you should
be OK. Is it?
Yes, I could specify these as fixtures, but I really don't want to
have to specify 15-20 fixtures on every example. Yes, I could mock/
stub all the values, except that I use many of these values at class
definition time, which means that errors are thrown before I can
even mock/stub.
For instance, I have a statement like this.
named_scope :open, :conditions => ["lead_status_id IN (?)", %w{New
Incubating Client UAG}.collect{|x| LeadStatus[x].id}]
Which loads the named_scope using the string version of the
enumeration for clarity's sake. It works great, except for testing.
Does anybody see anyway around this other than creating a fixture
file for each of these tables and loading all the fixtures on each
describe block. Not only does this make for ugly code, but I'm sure
it takes a good chunk of time to setup and teardown each of the
tables each example.
It would be wonderful if there was some option to specify tables
that behave like this, that should be loaded at the beginning of the
test run, and (optionally) trashed at the end of the run. Or even
better, specify that the test script shouldn't touch (build or
teardown) these tables at all, and let their migrated state remain.
Thanks,
Andrew
