  Python unit testing framework, based on Erich Gamma's JUnit and Kent Beck's
  Smalltalk testing framework (used with permission).
  
  This module contains the core framework classes that form the basis of
  specific test cases and suites (TestCase, TestSuite etc.), and also a
  text-based utility class for running the tests and reporting the results
   (TextTestRunner).
  
  Simple usage:
  
      import unittest
  
      class IntegerArithmeticTestCase(unittest.TestCase):
          def testAdd(self):  # test method names begin with 'test'
              self.assertEqual((1 + 2), 3)
              self.assertEqual(0 + 1, 1)
          def testMultiply(self):
              self.assertEqual((0 * 10), 0)
              self.assertEqual((5 * 8), 40)
  
      if __name__ == '__main__':
          unittest.main()
  
  Further information is available in the bundled documentation, and from
