+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()
