  1. some of the answers are wrong

  2. Hello Nawab,

    Corrected the typo errors for the questions:

    Bug Q.35-C is correct answer:
    The ISO 9126-1 software quality model identifies 6 main quality characteristics, namely:

  3. Q no 35...Ans should be b)pole coverage

    1. I beg your pardon Nabanita.
      I think you are asking for the question 34.
      However, I have corrected the Question: 34 with the correct answer: b)Pole Coverage.
      Thanks for pointing the error.

  4. Is the answer for Q:23 correct?
    I guess i should be D instead of C.

    1. Hello sk,

      The correct answers is C.
      As first we get the requirement then we do the design.
      So if we have a bug in the requirement then design is also buggy.
      So we have to fix the bug from the requirement phase which will lead to have a new design.
      So, faults in requirements are the most expensive to fix.


  5. I think, question #30 have correct answer is C instead of b. Please confirm

    1. Hello Harish,

      The correct answer for question#30 is B.
      As you can see in the question it will accept numbers between 10 to 21.
      So the MOST boundary values that covers will be: 9,10,21,22.
      That is what we check in 'Boundary Value' testing.

      According to ISTQB:
      Boundary value analysis (BVA) is based on testing at the boundaries between partitions. If you have ever done 'range checking', you were probably using the boundary value analysis technique, even if you weren't aware of it. Note that we have both valid boundaries (in the valid partitions) and invalid boundaries (in the invalid partitions).
      As an example, consider a printer that has an input option of the number of copies to be made, from 1 to 99.
      To apply boundary value analysis, we will take the minimum and maximum (boundary) values from the valid partition (1 and 99 in this case) together with copies to be made, from 1 to 99.

      The first or last value respectively in each of the invalid partitions adjacent to the valid partition (0 and 100 in this case). In this example we would have three equivalence partitioning tests (one from each of the three partitions) and four boundary value tests.

      So in the end we get: 0,1,99,100


  6. Dear ISTQB Team - Could you please provide a list of all testing standard in a tabular format so that it will be easier for me to remember.For example: Question 21 & 22...As we have so many testing standards for different kind of testing, will that be possible for you to provide all of them in a subtle way or in 2*2 table. Or please write the answer in front of these below:
    a. IEEE829 -
    b. IEEE610 -
    c. BS7925-1 -
    d. BS7925-2 - Component Test Standard

    would be highly appreciated,Thanks - Mukta

    1. Hi Mukta, here it is:

      IEEE 730 - SW Quality Assurance plan
      IEEE 829 - SW & system test documentation
      IEEE 1008 - Unit testing
      IEEE 1012 - SW verification/validation
      IEEE 1028 - SW inspections
      IEEE 1044 - classification of SW anomalies
      IEEE 12207 - SW life cycle process and life cycle data
      BS 7925-1 - vocabulary & testing terms
      BS 7925-2 - SW component testing

  7. If answer for Question 36 is B, can you please provide a similar example to show the usage of Stubs..? As per Section 2.2.1 in ISTQB Book -
    Most often stubs and drivers are used to replace the missing software and simulate the interface between the software components in a simple manner. A stub is called from the software component to be tested; a driver calls a component to be tested...
    Still,am not sure on the question you have asked...Please elaborate,if possible. Thanks - Mukta

    1. Hi Mukta,

      let's consider a following class that you want to test automaticaly:

      public class ToTest() {

      ....private InternalService internalService;

      ....public static void methodToTest() {
      ........if (internalService.checkSomething()) {
      ............return true;
      ........} else {
      ............return false;

      1. You need some script/program that would invoke this class (that would create an instance and invoke methodToTest()). This piece of a software you'd call Driver
      2. Note that class ToTest requires also and instance of InternalService so you can create a Stub (or Mock) and inject it into this class. The purpose of Stub/Mock is to simulate (record) behavior of InternalService. Since you want to test only ToTest class you need to mock all it's dependencies.

      There is one additional word I used - Mock. For the purpose of this post I used them interchangeably but these in fact are not the same, there is a nice article about the differences:

  8. Hi, it seems to me that the answer to question #37 is wrong. There are two "if" statements so in fact we need 2^2 scenarios to cover all paths which is 4 while the answer says that we need only 3. Please advise.

    1. This comment has been removed by the author.

    2. Let me just add one more information. In Question paper 5, question 14 is exactly the same, and the answer is as I would expect -> 4.

    3. yes , i noted the same why the ans for the same question in different test papers is different

  9. This comment has been removed by the author.

  10. hi ISTQB team, i read this blog first time. really appreciate your work
    you provide good support. i shall be thankful to you for this activity .

  11. Hi! Could you elaborate on the result of question 37?
    I first got the question a bit wrong and thought I should count testcases to cover all statements. In this case only 2 cases would be needed. -> (cond1 true + cond2 true):statement1 and 3 covered and (cond1 false):statement 2 covered ...
    But ok, text says all possible combinations of statements. So we have 3 statements S1, S2 and S3. According to the code all possible combinations would be S1, S2, S1+S3, S2+S3 (the first two combinations when cond3 is false) -> makes 4 combinations and thus 4 test-cases necessary.
    Hope someone can explain why the solution given here is 3?

    1. I was also looking at that question and I also got either 2 or 4.

  12. I agree with you Gordon ,I too got the answer for question 37 as 4 , please can some one explain why the answer is 3?

  13. Hello people,

    I have my ISTQB exam in another week and I have recently encountered this site(which I think is awesome), I was wondering if this set of 33 sample papers are good enough to practice before attempting the final one , or do I require to google search for other set of questionnaire.

    Response is highly appreciated.


  14. Hi Friends.
    My exam is in 14 Sept 2013
    Please tell me if these questions are enough or there is need to buy dumps from any other website.
    Please answer me

  15. how was your exam did you guys clear it?

  16. ans given for q. no 23 is not correct.. becoz the later is the bug found , it wl be more expensive to fix that bug and requirement stage is the first step of sdlc.

    1. as requirement is the initial stage, if there is a fault in the initial step itself, the work done in later steps will become wrong.Once we relealise the fault in requirement, then it is a rework and reinstallment of money, that y it has been answered as c

  17. why 31 is C ? I think D is the correct

    1. Hi Zhao,
      Please check 4.3.2 Boundary Value Analysis(K3) from ISTQB foundation level syllabus 2011.
      “Tests cab be designed to cover both valid and invalid boundary values.”
      Answer “C” has both valid (1900,2004) and invalid(1899,2005) boundary values. Why do you think that there should be one more pair of valid values(1901,2003) be there?

  18. 29Q answer is A
    10,11,21 all three values are accepted values so all three will fall under equivalence partition, can you please check and correct.

    1. Hi Pradeep,
      The question is about “cover all of the equivalence partitions”. So you should cover all three partitions (RejectAcceptReject) not just the accept one(10 to 21).

  19. Can you explain question 38.)

  20. This comment has been removed by the author.

  21. Could please explain why the answer for Q5 is d, it should be a

  22. Hi guys,

    Could you please explain me why 3 test case are needed for statement and branch coverage in the Q17 and Q18?
    Why it is not enough, for example, to use the 2 following ones:
    1) x=3, y=2;
    2) x=1, y=5?

    1. I think we need to consider another case x=3,y=5 or x=1,y=2.

  23. This comment has been removed by the author.

  24. for Q37 the right answer is 4 test cases. Ithink that the variants should be:
    a. 2
    b. 3
    c. 4
    d. None of the above
    And then the correct answer would be c.

  25. HI, i have doubt about this answer. can any one explain this answer plz.
    1.Software testing activities should start

    a. as soon as the code is written
    b. during the design stage
    c. when the requirements have been formally documented
    d. as soon as possible in the development life cycle

  26. Dear ISTQB Team,
    Q19. Which of the following is NOT a type of non-functional test?
    a. State-Transition
    b. Usability
    c. Performance
    d. Security
    Security test is mentioned is Function test--> in Syllabus, 2.3.1 in page 28 of Syllabus book
    in wikipedia link is non-function:
    ---> I really confuse about Security is function or non-function test

  27. I agree with the above comment about Q19. The ISEB/ISTQB book specifically says security testing is considered functional testing.

  28. Really nice topics you had discussed above. I am much impressed. Thank you for providing this nice information here.
