 | 
						|
Python unit testing framework, based on Erich Gamma's JUnit and Kent Beck's
 | 
						|
Smalltalk testing framework.
 | 
						|
 | 
						|
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 IntegerArithmenticTestCase(unittest.TestCase):
 | 
						|
        def testAdd(self):  ## test method names begin 'test*'
 | 
						|
            self.assertEquals((1 + 2), 3)
 | 
						|
            self.assertEquals(0 + 1, 1)
 | 
						|
        def testMultiply(self):
 | 
						|
            self.assertEquals((0 * 10), 0)
 | 
						|
            self.assertEquals((5 * 8), 40)
 | 
						|
 | 
						|
    if __name__ == '__main__':
 | 
						|
        unittest.main()
 | 
						|
 | 
						|
