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()
|
|
|
|
