Redeem测试

传入数据需满足：v = v_old - v_s v_s < v_old

---

v_old/value_old:转换前零知识余额对应的明文余额

v_s/value_s:需要被转换的明文余额

v/value：转换后零知识余额对应的明文余额

---

理想测试：

uint64_t value = uint64_t(13); 
uint64_t value_old = uint64_t(20); 
uint64_t value_s = uint64_t(7);

结果：Verifying redeem proof successfully!

---

v > v_old - v_s

uint64_t value = uint64_t(14); 
uint64_t value_old = uint64_t(20); 
uint64_t value_s = uint64_t(7);

结果：generate redeem proof fail!

---

v < v_old - v_s

uint64_t value = uint64_t(12); 
uint64_t value_old = uint64_t(20); 
uint64_t value_s = uint64_t(7);

结果：generate redeem proof fail!

---

v_s = 0

uint64_t value = uint64_t(12); 
uint64_t value_old = uint64_t(12); 
uint64_t value_s = uint64_t(0);

结果：Verifying redeem proof successfully!

---

v_s = 0 v_old = 0 v=0

uint64_t value = uint64_t(0); 
uint64_t value_old = uint64_t(0); 
uint64_t value_s = uint64_t(0);

结果：generate redeem proof fail!

---

v_s = v_old

uint64_t value = uint64_t(0); 
uint64_t value_old = uint64_t(12); 
uint64_t value_s = uint64_t(12);

结果：generate redeem proof fail!

---

v_s > v_old

uint64_t value = uint64_t(-1); 
uint64_t value_old = uint64_t(12); 
uint64_t value_s = uint64_t(13);

结果：generate redeem proof fail!

验证proof时的测试参数及测试结果 （1）sn_old，value_s，cmtA_old，cmtA为生成proof时的正确参数：

uint256 sn_old = uint256S("123456");
uint256 cmtA_old = note_old.cm();
uint256 cmtA = note.cm();
uint64_t value_s = uint64_t(7);

验证proof通过，结果: Verifying send proof successfully!!!

---

（2）value_s，cmtA_old，cmtA为生成proof时的正确参数，sn_old为错误参数：

uint256 wrong_sn_old = uint256S("666");
uint256 cmtA_old = note_old.cm();
uint256 cmtA = note.cm();
uint64_t value_s = uint64_t(7);

验证proof不通过，结果: Verifying redeem proof unsuccessfully!!!

---

（3）sn_old，cmtA_old，cmtA为生成proof时的正确参数，value_s为错误参数:

uint256 sn_old = uint256S("123456");
uint256 cmtA_old = note_old.cm();
uint256 cmtA = note.cm();
uint64_t wrong_value_s = uint64_t(8);

验证proof不通过，结果: Verifying redeem proof unsuccessfully!!!

（4）sn_old，value_s，cmtA为生成proof时的正确参数，cmtA_old为错误参数:

uint256 sn_old = uint256S("123456");
uint256 wrong_cmtA_old = note.cm();
uint256 cmtA = note.cm();
uint64_t value_s = uint64_t(7);

验证proof不通过，结果: Verifying redeem proof unsuccessfully!!!

（5）sn_old，value_s，cmtA_old为生成proof时的正确参数，cmtA为错误参数:

uint256 sn_old = uint256S("123456");
uint256 cmtA_old = note_old.cm();
uint256 wrong_cmtA = note_old.cm();
uint64_t value_s = uint64_t(7);

验证proof不通过，结果: Verifying redeem proof unsuccessfully!!!
