[Tutor] Unittest traceback

[Oleg Oltar]

Hi!
I am trying to use unittest in python first time. But have a strange
traceback each time I run my sample tests.
Can you please explain why I have it. No info about it in the doc.
e.g. the code is

import unittest
import squaren

class TestCases(unittest.TestCase):
    def setUp(self):
        pass

    def testsmall(self):
        self.assertEqual(True, True)



if __name__ == '__main__':
    unittest.main()

And the traceback is

----------------------------------------------------------------------
Ran 1 test in 0.000s

OK
Traceback (most recent call last):
  File "/tmp/py359hJx", line 14, in <module>
    unittest.main()
  File "/opt/local/lib/python2.5/unittest.py", line 768, in __init__
    self.runTests()
  File "/opt/local/lib/python2.5/unittest.py", line 806, in runTests
    sys.exit(not result.wasSuccessful())
SystemExit: False
