assertItemsEqual was removed from Python's unittest.TestCase in Python 3.3 [1][2]. We have been able to use them since then, because testtools required unittest2, which still included it. With testtools removing Python 2.7 support [3][4], we will lose support for assertItemsEqual, so we should switch to use assertCountEqual.
