# Script to run a "Ravenwood" host side test.
#
# A proper way to run these tests is to use `atest`, but `atest` has a known issue of loading
# unrelated jar files as the class path, so for now we use this script to run host side tests.

# Copy (with some changes) some functions from ../common.sh, so this script can be used without it.
