# *********************************************************
# The aim of this testcase is to test the functionality
# of the multiple get functionality
# case 1: be able to get correct value from mutliple get
# case 2: If there is no corresponding value for a key
#         should not affect the other values in fetching
# case 3: No support for switch between the tables
