/* ----------------- Basic ring buffer behavior tests cases --------------------
|
|
* The following set of test cases will test basic send, receive, wrap around and buffer full
|
|
* behavior of each type of ring buffer.
|
|
* Test Case 1:
|
|
* 1) Send multiple items (nearly fill the buffer)
|
|
* 2) Receive and check the sent items (also prepares the buffer for a wrap around)
|
|
* 3) Send a final item that causes a wrap around
|
|
* 4) Receive and check the wrapped item
|
|
*
|
|
* Test Case 2:
|
|
* 1) Send multiple items (completely fill the buffer)
|
|
* 2) Send another item and verify that send failure occurs
|
|
* 3) Receive one item and verify that space is freed up in the buffer
|
|
* 4) Receive and check the remaining sent items
|
|
*
|
|
* Test Case 3:
|
|
* 1) Send multiple items (nearly fill the buffer)
|
|
* 2) Send another small sized item to fill the buffer without causing a wrap around (not needed in case of byte buffer)
|
|
* 2) Send another item and verify that send failure occurs
|
|
* 4) Receive and check the sent items
