magicciv/scripts/dev-setup/test_bluefin.sh

#!/usr/bin/env bash
# Smoke tests for scripts/dev-setup/bluefin.sh.
#
# Runs locally on the EDIT host without any bluefin/bootc prereqs —
# exercises the shell logic via bash -n (parse) and the --help / --check
# argument paths, which must not require sudo or rpm-ostree on the caller.
#
# Usage:
#   bash scripts/dev-setup/test_bluefin.sh           # run all tests
#   bash scripts/dev-setup/test_bluefin.sh -v        # verbose
#
# Exit codes:
#   0  all tests passed
#   1  at least one test failed
#
# Wired into CI via `./run verify` → scripts/run/verify.sh once that lands.
