"""Test that the wallet can send and receive using all combinations of address types. |
||||
|
||||
There are 4 nodes-under-test: |
||||
- node0 uses legacy addresses |
||||
- node1 uses p2sh/segwit addresses |
||||
- node2 uses p2sh/segwit addresses and bech32 addresses for change |
||||
- node3 uses bech32 addresses |
||||
|
||||
node4 exists to generate new blocks. |
||||
|
||||
The script is a series of tests, iterating over the 4 nodes. In each iteration |
||||
of the test, one node sends: |
||||
- 10/101th of its balance to itself (using getrawchangeaddress for single key addresses) |
||||
- 20/101th to the next node |
||||
- 30/101th to the node after that |
||||
- 40/101th to the remaining node |
||||
- 1/101th remains as fee+change |
||||
|
||||
Iterate over each node for single key addresses, and then over each node for |
||||
multisig addresses. In a second iteration, the same is done, but with explicit address_type |
||||
parameters passed to getnewaddress and getrawchangeaddress. Node0 and node3 send to p2sh, |
||||
node 1 sends to bech32, and node2 sends to legacy. As every node sends coins after receiving, |
||||
this also verifies that spending coins sent to all these address types works.""" |
