# The line below specified that line under it should be used as the test's short description when launching test via run_tests script.
# The text should not be longer than 80 chars - if it is, the script will strip addititonal characters
# DESCRIPTION Check if casctl stop/start handles flushing/loading properly

# The line below says that this test should be included in BVT - it will be launched, when we use "./run_tests -b"

# USE_IN_NIGHTLY

# Standard beginning for every test - get the main tests directory and
# link the cas_lib file for CAS API, then use "start_test $*" to pass params
# and do other necessary checks and setup
TESTS_DIR="$(dirname $0)/../"
. $TESTS_DIR/cas_lib
start_test $*

# This is where the real test starts
