"""Test the abandontransaction RPC.
|
|
|
|
The abandontransaction RPC marks a transaction and all its in-wallet
|
|
descendants as abandoned which allows their inputs to be respent. It can be
|
|
used to replace "stuck" or evicted transactions. It only works on transactions
|
|
which are not included in a block and are not currently in the mempool. It has
|
|
no effect on transactions which are already conflicted or abandoned.
