# This script can be used to test the 'install.sh' and 'verify'sh'
# scripts locally without running the 3pp LUCI recipe.
# Usage:
#    ./test_locally.sh <BAZEL_BIN> <BAZEL_VERSION>
#
# Where <BAZEL_BIN> points to the real Bazel binary (note that 'bazel'
# can be a wrapper script to the real binary, e.g. it would be
# /usr/bin/bazel-real on a Debian based system).
#
# Where <BAZEL_VERSION> is the Bazel build label for said binary.
# (which can be obtained with `bazel info`
#
# E.g.:
#    ./test_locally.sh /usr/bin/bazel-real 5.2.0
