A program reads an integer number within the range [0, 200] and determines whether it is an even number or not. Design test cases for this program using BVC, robust and worst case testing methods.

Test cases using BVC

Since there is only one variable for finding number is even or not, the total test cases will be 4n + 1 = 5

$\therefore$ min value = 0

maximum value = 200

minimum + value = 1

maximum - value = 199

nominal value = 100

Using this test cases designs are as follows.

Test case id	Integer value	Expected o/p
1	0	even no.
2	200	even no.
3	1	odd no.
4	199	odd no.
5	100	even no.

* Test cases using robust testing :*

$\therefore$ there is only one variable, total no. of test cases will be

6n + 1 = 7

min value = 0

max value = 100

min - value = -1

min + value = 1

max + value = 201

max - value = 199

nominal value = 100

Using these values, test cases can be designed as follows:

Test case ID	Integer value	Expected o/p
1	0	even no.
2	200	even no.
3	-1	odd no.
4	1	odd no.
5	201	odd no.
6	199	odd no.
7	100	even no.

Test cases using worst case testing : Since there is only one variable, the total number of test cases will be $5^n = 5$ Therefore the number of test cases will be same as BVC.
