Revert "bpo-45162: Remove many old deprecated unittest features (GH-28268)"
This reverts commit b0a6ede3d0.
We're deferring this change until 3.12 while upstream projects that use
the legacy assertion method names are fixed. See the issue for links
to the discussion. Many upstream projects now have issues and PRs
filed.

|
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()
|
|
|
|
