Chapter 8 of Sommerville covers Software Testing. Test cases are representative numbers to test a co program written in C, Java etc. To test a program with 100 possible inputs, you do not need to try all 100 possibilities, usually 2, 3, or 5 cases may suffice if you pick appropriately (a) To test a square function that computes the square of integer n for n = 1 to 100, design tree working test cases with n between 1 and 100 that somehow explain this function works to compute the square of an integer (note you do not have to design 100 cases). Design two nonworking cases such as n-1 and explain what you expect for the nonworking case. r people to order a book to type in their first name, street address, and quantity. Design two working (valid) cases and two invalid cases
