[issue27071] unittest.TestCase.assertCountEqual is a very misleading name

Vitaly added the comment:

Same results on Python.org's Python 3.5.1 shell:
>>> class Test(u.TestCase):
...     def test_equal_count_of_same_elements(self):
...         self.assertCountEqual(set([1,2,3]), set([1,2,3]))
...     def test_equal_count_of_different_elements(self):
...         self.assertCountEqual(set([1,2,3]), set([1,2,4]))
...     def test_different_count(self):
...         self.assertCountEqual(set([1,2,3]), set([1,2,3,4]))
... 
>>> u.main()
FF.
