I put together a proof of concept of this exact functionality using 
fixtures.Fixture and a context manager called acting_as() [1] that was 
extended by subclasses' do_as() method [2] to make it easy to write 
clean impersonation code [3]:

class TestFlavorsNonAdmin(base.ComputeApiTest):

     def test_list_flavors(self):
         with self.do_as('non_admin') as client:
             flavors = client.flavors.list()
             self.assertTrue(len(flavors) > 0)

     def test_unauthorized(self):
         with self.do_as('non_admin') as client:
             self.assertRaises(Exception, client.flavors.create, 
'flavorname')


class TestFlavorsAdmin(base.ComputeApiTest):

     def test_list_flavors(self):
         with self.do_as('admin') as client:
             flavors = client.flavors.list()
             self.assertTrue(len(flavors) > 0)

     def test_crud(self):
         with self.do_as('admin') as client:
             flavor_name = self.getUniqueString("flavor")
             flavor = client.flavors.create(flavor_name, 64, 1, 10)
             self.assertEqual(flavor_name, flavor.name)
             self.assertEqual(64, flavor.ram)
             self.assertEqual(1, flavor.vcpus)
             self.assertEqual(10, flavor.disk)
             flavors = client.flavors.list()
             flavor_ids = [x.id for x in flavors]
             self.assertIn(flavor.id, flavor_ids)
             flavor = client.flavors.find(name=flavor_name)
             self.assertEqual(flavor_name, flavor.name)
             self.assertEqual(64, flavor.ram)
             self.assertEqual(1, flavor.vcpus)
             self.assertEqual(10, flavor.disk)
             client.flavors.delete(flavor.id)
