#
# exit_state_action sysvar specifies which action is taken by a server once it
# has involuntarily left the group. Currently there are only two actions:
# either the server continues running but with super_read_only enabled
# (READ_ONLY) or it aborts (ABORT_SERVER).
#
# This test verifies that the sysvar behaves as expected, meaning that the
# default value is the expected one (READ_ONLY), that we can change it
# and the value is maintained and that invalid values result in error.
#
# Test:
# 0) The test requires one server.
# 1) Check the default value. It should be READ_ONLY.
# 2) Set the sysvar to the possible valid values. Verify that the valid values
#    are accepted with no error and the values are set correctly.
# 3) Set the sysvar to invalid values. There should be an error and the value of
#    the sysvar should not be altered.
# 4) Cleanup.
