	steps:
	- name: Checkout repository
	uses: actions/checkout@v4

	- name: Check and install CMake if needed
	# lnd_grpc_rust (via prost-build) requires CMake >= 3.5.
	# Since ubuntu-latest is not a fixed version,
	# a future update could include a lower CMake version.
	# This step ensures the correct version is installed.
	run: \|
	if ! command -v cmake &> /dev/null \|\| [ "$(cmake --version \| head -n1 \| cut -d' ' -f3)" \< "3.5" ]; then
	sudo apt-get update
	sudo apt-get install -y cmake

	- name: Set permissions for LND data directory
	# In PR 4622 (https://github.com/lightningnetwork/lnd/pull/4622),
	# LND sets file permissions to 0700, preventing test code from accessing them.
	# This step ensures the test suite has the necessary permissions.
	run: sudo chmod -R 755 $LND_DATA_DIR

	LND_DATA_DIR: ${{ env.LND_DATA_DIR }}

	run: LND_CERT_PATH=$LND_DATA_DIR/tls.cert LND_MACAROON_PATH=$LND_DATA_DIR/data/chain/bitcoin/regtest/admin.macaroon
	RUSTFLAGS="--cfg lnd_test" cargo test --test integration_tests_lnd -- --exact --show-output
