/*
* Ring
* ====
*
- * #. Basic tests: done on one core:
- *
- * - Using single producer/single consumer functions:
- *
- * - Enqueue one object, two objects, MAX_BULK objects
- * - Dequeue one object, two objects, MAX_BULK objects
- * - Check that dequeued pointers are correct
- *
- * - Using multi producers/multi consumers functions:
- *
- * - Enqueue one object, two objects, MAX_BULK objects
- * - Dequeue one object, two objects, MAX_BULK objects
- * - Check that dequeued pointers are correct
- *
- * - Test watermark and default bulk enqueue/dequeue:
- *
- * - Set watermark
- * - Set default bulk value
- * - Enqueue objects, check that -EDQUOT is returned when
- * watermark is exceeded
- * - Check that dequeued pointers are correct
- *
- * #. Check quota and watermark
- *
- * - Start a loop on another lcore that will enqueue and dequeue
- * objects in a ring. It will monitor the value of quota (default
- * bulk count) and watermark.
- * - At the same time, change the quota and the watermark on the
- * master lcore.
- * - The slave lcore will check that bulk count changes from 4 to
- * 8, and watermark changes from 16 to 32.
- *
- * #. Performance tests.
- *
- * This test is done on the following configurations:
- *
- * - One core enqueuing, one core dequeuing
- * - One core enqueuing, other cores dequeuing
- * - One core dequeuing, other cores enqueuing
- * - Half of the cores enqueuing, the other half dequeuing
- *
- * When only one core enqueues/dequeues, the test is done with the
- * SP/SC functions in addition to the MP/MC functions.
- *
- * The test is done with different bulk size.
+ * #. Functional tests. Tests single/bulk/burst, default/SPSC/MPMC,
+ * legacy/custom element size (4B, 8B, 16B, 20B) APIs.
+ * Some tests incorporate unaligned addresses for objects.
+ * The enqueued/dequeued data is validated for correctness.
*
- * On each core, the test enqueues or dequeues objects during
- * TIME_S seconds. The number of successes and failures are stored on
- * each core, then summed and displayed.
- *
- * The test checks that the number of enqueues is equal to the
- * number of dequeues.
+ * #. Performance tests are in test_ring_perf.c
