Take any message of length, say, 45. Init the key and counter, and encrypt. Then start again with the same message, key, and counter. Encrypt the first x bytes, and then the remaining 45-x (both in place). You should get the same answer. If you do this with x = 0,1,7,8,9,15,16,17,22, that should be a good set of test cases, I think.
