 * This test case performs the following actions:
 *
 * - Validate the signal constant.
 *
 *   - Check that the signal constant is equal to the integer representation of
 *     the signal in the signal set.
 *
 * - Validate the signal delivery.
 *
 *   - Check that the caught signal set represents exactly the sent signal.
