"""Test the wallet backup features.
2014-12-04 22:09:58 +01:00
Test case is:
4 nodes. 1 2 and 3 send transactions between each other,
fourth node is a miner.
1 2 3 each mine a block to start, then
Miner creates 100 blocks so 1 2 3 each have 500 mature
2014-12-04 22:09:58 +01:00
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 and mining a block.
Miner then generates 101 more blocks, so any
transaction fees paid mature.
Sanity check:
Sum(1,2,3,4 balances) == 114*500
2014-12-04 22:09:58 +01:00
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.

Merge #13054: tests: Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports. 68400d8b96 tests: Use explicit imports (practicalswift) Pull request description: Enable automatic detection of undefined names in Python tests scripts. Remove wildcard imports. Wildcard imports make it unclear which names are present in the namespace, confusing both readers and many automated tools. An additional benefit of not using wildcard imports in tests scripts is that readers of a test script then can infer the rough testing scope just by looking at the imports.
