 * @brief This test case collection provides validation test cases for
 *   requirements of the @ref RTEMSAPIClassicPart.
 *
 * This test case performs the following actions:
 *
 * - Create a partition with a buffer area length which is greater than three
 *   times the buffer size and less than four times the buffer size.
 *
 *   - Check that exactly three buffers can be obtained from the partition for
 *     use in parallel.
 *
 *   - Return the three buffers in use to the partition and check that they can
 *     be obtained from the partition for use in parallel in FIFO order.
 *
 * - Assert that RTEMS_PARTITION_ALIGNMENT is a constant expression which
 *   evaluates to the expected value.
