+            Consider a Program to print even or odd number.
+            The code in the Test case Field should be as follows: ::
+
+                source("function.r")
+                check_empty = function(obj){
+                    stopifnot(is.null(obj) == FALSE)
+                }
+                check = function(input, output){
+                stopifnot(input == output)
+                }
+                is_correct = function(){
+                if (count == 3){
+                    quit("no", 31)
+                }

+                check_empty(odd_or_even(3))
+                check(odd_or_even(6), "EVEN")

+                count = 3
+                is_correct()
+
+            Assuming Students answer to be as below: ::
+
+                odd_or_even <- function(n){
+                  if(n %% 2 == 0){
+                    return("EVEN")

+                  return("ODD")
+                }
