# This is a smoke test of bcachefs-tools.
#
# It builds the source with multiple options (debug, release, valgrind, FUSE)
# and runs the test suite.
#
# Returns 0 on success, nonzero on any failure.
#
# Dependencies:
#
# valgrind, python3-pytest, python3-pytest-xdist
#
# On debian/ubuntu based systems, install with:
#
#   apt install valgrind python3-pytest python3-pytest-xdist
#
# You also currently need fuse 3.7 or later.  Fuse 3.7 unfortunately requires
# debian sid or bullseye at this time, so you may need to install from source.
