* Test Synopsis:
* - Test CV linked list management.
*
* Test Method (Validation or Falsification):
* - Validation:
* Initiate and destroy several CVs in random order.
*
* Requirements Tested:
* -
*
* Features Tested:
* -
*
* Cases Tested:
* -
*
* Description:
* - Creates and then imediately destroys a CV. Does not
* test the CV.
*
* Environment:
* -
*
* Input:
* - None.
*
* Output:
* - File name, Line number, and failed expression on failure.
* - No output on success.
*
* Assumptions:
* -
*
* Pass Criteria:
* - All initialised CVs destroyed without segfault.
* - Successfully broadcasts all remaining CVs after
* each CV is removed.
*
* Fail Criteria:
