"""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. |
