36 * Test Synopsis:
37 * - Test CV linked list management.
38 *
39 * Test Method (Validation or Falsification):
40 * - Validation:
41 * Initiate and destroy several CVs in random order.
42 *
43 * Requirements Tested:
44 * -
45 *
46 * Features Tested:
47 * -
48 *
49 * Cases Tested:
50 * -
51 *
52 * Description:
53 * - Creates and then imediately destroys a CV. Does not
54 * test the CV.
55 *
56 * Environment:
57 * -
58 *
59 * Input:
60 * - None.
61 *
62 * Output:
63 * - File name, Line number, and failed expression on failure.
64 * - No output on success.
65 *
66 * Assumptions:
67 * -
68 *
69 * Pass Criteria:
70 * - All initialised CVs destroyed without segfault.
71 * - Successfully broadcasts all remaining CVs after
72 * each CV is removed.
