"""Tests that fundrawtransaction correctly handles the case of sending many
|
|
inputs of an issued asset, with no policy asset recipient.
|
|
|
|
See: https://github.com/ElementsProject/elements/issues/1259
|
|
|
|
This test issues an asset and creates many utxos, which are then used as inputs in
|
|
a consolidation transaction created with the various raw transaction calls.
