In other words, nose the module doesn't handle optimized mode, and apparently nosetests cannot run in optimized mode.

On the other hand, unittest:
--------------------------------------
from unittest import TestCase, main

class TestTest(TestCase):
     def test_optimized(self):
         self.assertTrue(1 == 2)

if __name__ == '__main__':
     main()
--------------------------------------

ethan@media:~/source$ python3.4 test.py
Ran 1 test in 0.001s
FAILED (failures=1)

ethan@media:~/source$ python3.4 -O test.py
Ran 1 test in 0.001s
FAILED (failures=1)


I'll stick with unittest.
