  1. For question 33, I think answer is not correct. It should be c.

    Do the answers are verified & confirm?


  2. Are the answers given here correct? because I feel few of them are incorrect.

  3. This is the way of ISTQB and ISEB. Ignore the real world and answer how they want you to.

    As for question 33, the purpose of testing is to ensure to the best of your ability that the program doesn't do what it's not meant to. As a test analyst your job is to find defects and assure quality; measured against business specifications.

    As always each question has answers which could be correct, but you must state which is most correct ;)

  4. Question #29 should also be corrected. IEEE 829 refers to the document containing deviations as Test Incident Report, while this quiz says the right answer is Anomaly Report (wrong).

  5. As per question #33, I agree with Preet's statement on testing's main purpose is to show that the software does what is expected to do (or in other words, what the customer requested for the software to do).

    Finding defects is part of the V&V process (a very important one), but an errors free software which doesn't fulfil the customer requirements is useless (and can't be approved for release).

    The right answer is 'C'.

  6. For question 33, it is the developer's job to make sure the system does what it is supposed to do. Testers looks for defects.
