We introduce Taproot support in the test framework through a global toggle. A few modifications are made to some tests to adapt them under Taproot (notably the hardcoded fees / amounts). This is based on my introduction of a quick and dirty support for TapMiniscript in my python-bip380 library: https://github.com/darosior/python-bip380/pull/23. In addition to this i didn't want to implement a signer in the Python test suite so here we introduce a simple Rust program based on our "hot signer" which will sign a PSBT with an xpriv provided through its stdin and output the signed PSBT on its stdout. Eventually it would be nicer to have a Python signer instead of having to call a program. The whole test suite should pass under both Taproot and P2WSH. Only a single test is skipped for now under Taproot since it needs a finalizer in the test suite. I also caught a bug in the RBF tests which i fixed in place.

Lianad blackbox tests
Here we test lianad by starting it on a regression testing Bitcoin network,
and by then talking to it as an user would, from the outside.
Python scripts are used for the automation, and specifically the pytest framework.
Credits: this test framework was taken and adapted from revaultd, which was itself adapted from C-lightning's test framework.
Building the project for testing
To run the tests, we must build the debug version of lianad. Follow the instructions at doc/BUILD.md but instead of running
$ cargo build --release
Run
$ cargo build
to build the daemon for testing.
The lianad and liana-cli binaries will be in the target/debug directory at the root of the
repository.
Test dependencies
Functional tests dependencies can be installed using pip. Use a virtual environment.
# Create a new virtual environment, preferably.
python3 -m venv venv
. venv/bin/activate
# Get the deps
pip install -r tests/requirements.txt
Additionaly you need to have bitcoind installed on your computer, please
refer to bitcoincore for installation. You may use a
specific bitcoind binary by specifying the BITCOIND_PATH env var.
Running the tests
From the root of the repository:
pytest tests/
For running the tests under Taproot a bitcoind version 26.0 or superior must be used. It can be
pointed to using the BITCOIND_PATH variable. For now, one must also compile the taproot_signer
Rust program:
(cd tests/tools/taproot_signer && cargo build --release)
Then the test suite can be run by using Taproot descriptors instead of P2WSH descriptors by setting
the USE_TAPROOT environment variable to 1.
Tips and tricks
Logging
We use the Live Logging
functionality from pytest. It is configured in (pyproject.toml)[../pyproject.toml] to
output INFO-level to the console. If a test fails, the entire DEBUG log is output.
You can override the config at runtime with the --log-cli-level option:
pytest -vvv --log-cli-level=DEBUG -k test_startup
Note that we record all logs from daemons, and we start them with log_level = "debug".
Test lints
Just use black.
