TestArray.KVStoreClass is not overridden in tests that inherit from TestArray

[d-v-b]

The TestArray class in test_core.py defines a class attribute called KVStoreClass that is assigned to KVStore (or KVStoreV3 in the v3 version of the test class), and this value is used in just one test: test_array_init. test_array_init only references self once, to get the KVStoreClass for instantiation before creating an array with the init_array -> Array sequence.

Because none of the V2 test array classes inheriting from TestArray override KVStoreClass, and none of them override test_array_init, it seems like this test is identical for each V2 subclass of TestArray, and therefore not needed.

Is this assessment correct, or did I miss something here?
