Replace-by-fee regression tests
|
||||
===============================
|
||||
|
||||
First get version v0.5.0 of the python-bitcoinlib library. In this directory
|
||||
run:
|
||||
|
||||
git clone -n https://github.com/petertodd/python-bitcoinlib
|
||||
(cd python-bitcoinlib && git checkout 8270bfd9c6ac37907d75db3d8b9152d61c7255cd)
|
||||
|
||||
Then run the tests themselves with a bitcoind available running in regtest
|
||||
mode:
|
||||
|
||||
./rbf-tests.py
