Mixin defining test helpers common to multiple types of constants collections.

Method	_notInstantiableTest	Assert that an attempt to instantiate the constants class raises `TypeError`.
Method	_initializedOnceTest	Assert that `container._enumerants` does not change as a side-effect of one of its attributes being accessed.

def _notInstantiableTest(self, name, cls):

Assert that an attempt to instantiate the constants class raises TypeError.

Parameters	name	A `str` giving the name of the constants collection.
	cls	The constants class to test.

def _initializedOnceTest(self, container, constantName):

Parameters	container	A `_ConstantsContainer` subclass which will be tested.
	constantName	The name of one of the constants which is an attribute of `container`.
