You mean like this?

$ cat skiptest.py
import unittest
import sys

def hide_if(condition):
    def g(f):
        return None if condition else f
    return g

class T(unittest.TestCase):
    @hide_if(sys.version_info[0] > 2)
    def test_two(self):
        pass
    @hide_if(sys.version_info[0] < 3)
    def test_three(self):
        pass

if __name__ == "__main__":
    unittest.main()
$ python skiptest.py -v
test_two (__main__.T) ... ok

OK
$ python3 skiptest.py -v
test_three (__main__.T) ... ok

Ran 1 test in 0.000s

OK

I don't understand that remark.
