| """Test HD Wallet keypool restore function. | |||||
| Two nodes. Node1 is under test. Node0 is providing transactions and generating blocks. | |||||
| - Start node1, shutdown and backup wallet. | |||||
| - Generate 110 keys (enough to drain the keypool). Store key 90 (in the initial keypool) and key 110 (beyond the initial keypool). Send funds to key 90 and key 110. | |||||
| - Stop node1, clear the datadir, move wallet file back into the datadir and restart node1. | |||||
| - connect node1 to node0. Verify that they sync and node1 receives its funds.""" | |||||
