## Note:
##    G_RECORD_LOCAL_CSV: when this environment variant is set to "TRUE",
##         the result will be recorded in a csv file in the following path:

##    G_VERBOSE_OUTPUT: when this environment variant is set to "TRUE", and only it is TRUE,
##         the verbose informain about the result will be outputed
##    G_RECORD_STATISTICS: only when this environment variant is set to "FALSE",
##         lava-test-case will be executed to report the result to LAVA for each raw data.
