""" |
||||
Exercise the wallet backup code. Ported from walletbackup.sh. |
||||
|
||||
Test case is: |
||||
4 nodes. 1 2 and 3 send transactions between each other, |
||||
fourth node is a miner. |
||||
1 2 3 each mine a block to start, then |
||||
Miner creates 100 blocks so 1 2 3 each have 50 mature |
||||
coins to spend. |
||||
Then 5 iterations of 1/2/3 sending coins amongst |
||||
themselves to get transactions in the wallets, |
||||
and the miner mining one block. |
||||
|
||||
Wallets are backed up using dumpwallet/backupwallet. |
||||
Then 5 more iterations of transactions and mining a block. |
||||
|
||||
Miner then generates 101 more blocks, so any |
||||
transaction fees paid mature. |
||||
|
||||
Sanity check: |
||||
Sum(1,2,3,4 balances) == 114*50 |
||||
|
||||
1/2/3 are shutdown, and their wallets erased. |
||||
Then restore using wallet.dat backup. And |
||||
confirm 1/2/3/4 balances are same as before. |
||||
|
||||
Shutdown again, restore using importwallet, |
||||
and confirm again balances are correct. |
