implementation of Multiple test case input

[cybermritunjay]

i want to add a functionality to compile the code against multiple test cases. any ideas how can i do so.
example:
i have a python code
def simpleArraySum(n,ar):
s = 0
for i in ar:
s += i
return s
n = int(raw_input().strip())
ar = map(int, raw_input().strip().split(' '))
result = simpleArraySum(n,ar)
print(result)

i want to test it against more then one inputs i.e. 6\n1 2 3 4 5 6 and 5\n5 6 9 8 7
