# Test Parameters:
# OPENBMC_HOST        The BMC host name or IP address.
# OS_HOST             The OS host name or IP Address.
# OS_USERNAME         The OS login userid (usually root).
# OS_PASSWORD         The password for the OS login.
# HTX_DURATION        Duration of HTX run, for example, 8 hours, or
#                     30 minutes.
# HTX_LOOP            The number of times to loop HTX.
# HTX_INTERVAL        The time delay between consecutive checks of HTX
#                     status, for example, 30s.
#                     In summary: Run HTX for $HTX_DURATION, looping
#                     $HTX_LOOP times checking every $HTX_INTERVAL.
# HTX_KEEP_RUNNING    If set to 1, this indicates that the HTX is to
#                     continue running after an error.
# CHECK_INVENTORY     If set to 0 or False, OS inventory checking before
#                     and after each HTX run will be disabled.  This
#                     parameter is optional.
# PREV_INV_FILE_PATH  The file path and name of an initial previous
#                     inventory snapshot file in JSON format.  Inventory
#                     snapshots taken before and after each HTX run will
#                     be compared to this file.
#                     This parameter is optional.  If not specified, an
#                     initial inventory snapshot will be taken before
#                     HTX startup.
