# Test wallet backup / dump / restore functionality
|
|
|
|
|
|
|
|
|
|
# Test case is:
|
|
|
|
|
# 4 nodes. 1 2 3 and send transactions between each other,
|
|
|
|
|
# fourth node is a miner.
|
|
|
|
|
# 1 2 3 and 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, then block.
|
|
|
|
|
#
|
|
|
|
|
# Miner then generates 101 more blocks, so any
|
|
|
|
|
# transaction fees paid mature.
|
|
|
|
|
#
|
|
|
|
|
# Sanity checks done:
|
|
|
|
|
# Miner balance >= 150*50
|
|
|
|
|
# Sum(1,2,3,4 balances) == 153*150
|
|
|
|
|
#
|
|
|
|
|
# 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.
