Yes, missing for single element enqueue/dequeue

The dequeued objects are checked against the enqueued objects for the bulk and burst APIs. Look at tests test_ring_burst_bulk_tests1..4. 'memcmp' is used to compare the enqueued objects against the dequeued ones.
Similar comparison can be added in test_ring_basic_ex, test_ring_with_exact_size functions.
