38 * Test Method (Validation or Falsification):
39 * -
40 *
41 * Requirements Tested:
42 * -
43 *
44 * Features Tested:

50 * Description:
51 * -
52 *
53 * Environment:
54 * -
55 *
56 * Input:
57 * - None.
58 *
59 * Output:
60 * - File name, Line number, and failed expression on failure.
61 * - No output on success.
62 *
63 * Assumptions:
64 * - have working pthread_create, pthread_self, pthread_mutex_lock/unlock
