Casting (uint16_t)data[0] of data[0] into a 16 bit unsigned int just
uses the 8 bit value in data[0] and not the 16 bit value from data[0]
with data[1]. A better way would be to defined a structure for this buffer
typedef struct {
uint16_t status;
uint16_t extended_status;
uint16_t validation_flags;
uint32_t data_loss_count;
uint8_t reserved[54];
} __attribute__ ((packed))nts_return_t;
..and cast this onto data
struct nts_return_t *nts_ret = (struct nts_return_t *)data;
and use the nts_return fields instead.
Same for all the return type in the tests you added.
