# Exercise the wallet. Ported from wallet.sh.
|
|
# Does the following:
|
|
# a) creates 3 nodes, with an empty chain (no blocks).
|
|
# b) node0 mines a block
|
|
# c) node1 mines 101 blocks, so now nodes 0 and 1 have 50btc, node2 has none.
|
|
# d) node0 sends 21 btc to node2, in two transactions (11 btc, then 10 btc).
|
|
# e) node0 mines a block, collects the fee on the second transaction
|
|
# f) node1 mines 100 blocks, to mature node0's just-mined block
|
|
# g) check that node0 has 100-21, node2 has 21
|
|
# h) node0 should now have 2 unspent outputs; send these to node2 via raw tx broadcast by node1
|
|
# i) have node1 mine a block
|
|
# j) check balances - node0 should have 0, node2 should have 100
|
|
# k) test ResendWalletTransactions - create transactions, startup fourth node, make sure it syncs
|
|
