Factorial Test Cases
n! means n(n-1)(n-2)……3,2,1First Check the given integer is positive If the given integer is negative,n! is not defined If the given number is fraction,n! is not defined check the given number is 0,n! is 1hope I’ll get an idea…if any wrong in this….correct me…
n! :n(n-1)(n-2)…..3,2,1.First TC: Check the given integer is positive If the given number is negative, ExpectedResult: n! is not defined If the given integer is a fraction. n! is not defined TC: check the given number is 0 (0!=1) ER: 1 is displayed Hope I’ll get an idea…correct if it’s wrong
Factorials are represented by n!
Examples: 3! = 1 * 2 * 3 = 6
4! = 1 * 2 * 3 * 4 = 24
5! = 1 * 2 * 3 * 4 * 5 = 120
A factorial program is easy to test because you are simply testing the input value for an integer variable related to a single text box and then verifying its output value. Here are the test cases:

Determine the maximum integer value that the computer can calculate its factorial. This value becomes the upper boundary.
POSITIVE TEST CASES
- Submit integer value at lower boundary [ 0 ]
- Submit integer value at lower boundary +1 [ 1 ]
- Submit integer value at the upper boundary -1
- Submit integer value at the upper boundary
NEGATIVE TEST CASES
- Submit integer value at upper boundary +1
- Submit integer value with leading 0
- Submit integer value with leading plus sign [+]
- Submit integer value with the leading minus sign [-]
- Submit integer value with leading space
- Submit number with a decimal point
- Submit number with the letter ‘e’ in it
- Submit alpha character(s)
- Submit special character(s) [ex: !@#$^]
- Submit with only space
- Submit with nothing entered
Factorial of a given number should not be negative numbers, decimal point numbers, alpha characters, special characters and if it is a function, it takes only one parameter.
