Check out TestSkipped.
It's already implemented as a part of utility functions for 
unittest module and heavily used in Lib/test directory.
Here's a simple example:

from test.test_support import TestSkipped

class AnythingTest(unittest.TestCase):
     def testSomethingAsRoot(self):
         if os.geteuid() != 0:
             raise TestSkipped, "Must be root"

         self.assertEqual(...)
         ...

     def testSomethingAsNormalUser(self):
         if os.geteuid() == 0:
             raise TestSkipped, "Must be normal user"
         self.skipIf(os.geteuid() == 0, "Must be normal user")

         self.assertEqual(...)
         ...
