Ah, your right! That test only verifies that null value that has been persisted, won’t throw and ArgumentNullException. In this case, the response should be a KEY_NOT_FOUND exception, since, well…the key doesn’t exist in the database.
If you would like to file a bug (so you can track the progress/resolution), you can do so here: http://www.couchbase.com/issues/browse/NCBC
