SEEMC ZG552 - SOFTWARE TESTING METHODOLOGIES

Time: 1.5 hrs Date: 23.03.2012 Max. Marks: 30

1. The following function, written in a Pascal-like pseudo-code, takes as input a

string assumed to be a URL and checks to see if it contains any characters that are

illegal. Illegal URL characters are control characters (0-31, 127 decimal), space(32 decimal), and delimiter characters (">", "":

valid = false;case "

For the following program, provide the following:

a. DD Path graph [2]b. The set of unique paths through the program [3]

c. For each feasible path, exact values of program variables that would cause

the path to be executed. [3]

d. Cyclomatic complexity [2]

2. Consider the specification given below. Identify the Causes and Effects in this

specification and then produce a cause effect graph showing their relationship.Using this truth table construct a set of test cases for this specification.

Specification: the basic cost of a health insurance premium is 100, however, thispremium can increase or decrease depending on two factors: their age and

whether they are a smoker. Customers who are above the age of 65 have their

insurance premium increased by 50. Customers who smoke have their premium

increased by 60. Customers whoare above the age of 65 and also smoke havetheir premium increased by 120 [5]

3. The basic cost of an insurance premium for drivers is 500, however, this

premium can increase or decrease depending on four factors: their age, theirgender, their marital status and number of penalty points. The input gender is

given by the character M for male and F for female. Drivers that are below the

age of 25, male and single face an additional premium increase of 1500. If adriver outside of this bracket is married or female their premium reduces by 200,

and if there are aged between 46 and 65 inclusive, their premium goes down by

100. Regardless of their status a driver will be charged an extra 20 for each

penalty point they have up to a maximum of 5. An entry of 0 is made for driverswith no penalty points

(1) int CarIns (int age, char gender, boolean married, int points) {

(2) Premium=500;(3) If ((age45) && (age5) {(14) points=5;

(15) }

(16) Premium = Premium + points*20;(17) return Premium;

(18) }

Derive test cases and test data for the following White Box Software testing

methods:i. Statement Testing [2]

ii. Condition Coverage Testing [3]

iii. Multiple Condition Coverage Testing [4]

4.

For the following binary search procedure.

1. int BSearch (List, Elem, LEN)

2. int LEN, List [LEN], Elem;

3. {

4. int high, low, mid;

5.

6. low = 1;

7. high = LEN-1;

8. mid = (low + high) / 2;

9. while (Elem != List[mid])

10.

{11. mid = (low + high) / 2;

12. if (high < low)

13. return (FALSE);

14. else if (Elem == List[mid])

15. return (TRUE);

16. else if (Elem > List[mid])

17. low = mid + 1;

18. else

19. high = mid - 1;

20. }

21.

return (TRUE);22. }

a. Give the required associations to satisfy All-Defs for the variable mid (both

definitions of mid). [2]b. Give the required associations to satisfy All-Uses for the variable mid (both

definitions of mid). [4]

NOTE:

1. The Question Paper has 3 printed Pages and 4 Questions.

2. The Questions which requires justification for answers will be awarded marksonly if justification is provided. Else no marks will be awarded.

3. Just Answer to the Question. Do not write additional things which are not

required. It will not fetch you any marks.

4. Copying is a serious offence. You will be severely penalized if there are evidencesleading to the confirmation of my suspicion
