|

* Description: Test the buffer count implementation.
|
|
*
|
|
* Test Type: Feature
|
|
*
|
|
* Targets: CIRC_CNT
|
|
*
|
|
* Inputs: None
|
|
*
|
|
* Steps:
|
|
* 1) Invoke CIRC_CNT in loop with head assigned with loop index value and
|
|
* tail as zero.
|
|
* 2) Check if the return value of buffer count is equal to loop index. Else
|
|
* return fail.
|
|
* 3) Invoke CIRC_CNT in loop with head assigned as maximum index and tail
|
|
* decreased according to the loop index value.
|
|
* 4) Check if the return value of buffer count is equal to loop index. Else
|
|
* return fail.
|
|
* 5) Invoke CIRC_CNT with both head and tail assigned with same value.
|
|
* 6) Check if the return value is equal to zero, else return fail.
|
|
* 7) Return PASS.
|
|
*
|
|
* Output:
|
|
* The test returns PASS if all the invocations of CIRC_CNT returns the
|
|
* expected value as buffer count. Otherwise, test returns FAIL.
