Q. 40: In system testing...
A. Both functional and non-functional requirements are to be tested
B. Only functional requirements are tested; non-functional requirements are validated in a
C. Only non-functional requirements are tested; functional requirements are validated in a review
D. Only requirements which are listed in the specification document are to be tested



  1. The answer of Q38 is wrong. The correct answer should be ‘C’.

    1. No, the right answer is indeed B because branch coverage=condition coverage=decision coverage. It's the same thing

  2. Q 26 answer is wrong.
    According to ISTQB Syllabus, section 2.3.1: "A type of functional testing, security testing, investigates the functions (e.g., a firewall) relating to detection of threats, such as viruses, from malicious outsiders."

    So the correct answer is 'D';
    the given answer 'A', State-Transition which is a black box technique has nothing to do with the question.
