/**
 * @file component_Testing.h
 * @brief A component that takes no actions, not even reads.
 *
 * This is useful to put in the stack around a component under test to
 * isolate it from the system and then intercept the queues.
 *
 * This component may be used as both TESTING_UPPER and TESTING_LOWER
 * to surround another component:
 *
 * { SYSTEM : COMPONENTS : [TESTING_UPPER, component under test, TESTING_LOWER] }
 *
 * In your test code, you would then have something like this to operate in
 * the "down" direction:
 *    PARCEventQueue *upper = rtaProtocolStack_GetPutQueue(stack, TESTING_UPPER, RTA_DOWN);
 *    PARCEventQueue *rea   = rtaProtocolStack_GetPutQueue(stack, component under test, RTA_UP);
 *    PARCEventQueue *lower = rtaProtocolStack_GetPutQueue(stack, TESTING_LOWER, RTA_UP);
 *
