"""Test wallet import RPCs.
|
|
|
|
Test rescan behavior of importaddress, importpubkey, importprivkey, and
|
|
importmulti RPCs with different types of keys and rescan options.
|
|
|
|
In the first part of the test, node 0 creates an address for each type of
|
|
import RPC call and sends BTC to it. Then other nodes import the addresses,
|
|
and the test makes listtransactions and getbalance calls to confirm that the
|
|
importing node either did or did not execute rescans picking up the send
|
|
transactions.
|
|
|
|
In the second part of the test, node 0 sends more BTC to each address, and the
|
|
test makes more listtransactions and getbalance calls to confirm that the
|
|
importing nodes pick up the new transactions regardless of whether rescans
|
|
happened previously.
