Consider a program that computes the factorial of a number (n).

ISTQB ISTQB-CTFL Question Answer

Consider a program that computes the factorial of a number (n). From the specifications you know that:

• I n < 0. a message "Value out of range" must be issued.

• If 0 < n < 100, the program calculates the factorial and returns the number

• If 100 < n < 200 message "Value out of range" must be issued

There are 3 partitions - one for negative numbers, one for numbers up to 100 and the last one for numbers up to 200

The equivalence partitions cannot be determined for this question because factorial of numbers close to 200 will be very large

The equivalence partitions cannot be determined for this question because the error message for two partitions is exactly same

The requirements are not correct because the partitions are overlapping
