ISTQB Questions for Foundation Level: Part 1

The International Software Testing Qualifications Board (ISTQB) is a software testing qualification certification organization that operates internationally. Their Foundation Level exam is of theoretical nature and requires knowledge in the field of software testing. We have listed out some sample ISTQB questions to help you with the certification. You can find the answers at the end of the exercise.

15. For which of the following would a static analysis tool be most useful?

16. Which of the following is a purpose of the review planning phase?
A. Log defects.
B. Explain the documents to the participants.
C. Gather metrics.
D. Allocate the individual roles.

17. Measurement dysfunction is a problem because:
A. Even though the numbers you look at appear better, to achieve these numbers, people are doing other aspects of their work much less well.
B. We don’t know how to measure a variable (our measurement is dysfunctional) and so we don’t know how to interpret the result.
C. You are measuring the wrong thing and thus reaching the wrong conclusions.
D. All of the above.

18. Typical defects that are easier to find in reviews than in dynamic testing are:
A. Deviations from standards,
B. Requirement defects,
C. Design defects,
D. Insufficient maintainability and incorrect interface specifications.

C. You have completed every test in the test plan.
D. You have reached the scheduled ship date.

21. Which of the following combinations correctly describes a valid approach to component testing:

C. That you have tested every IF statement in the program.
D. That you have tested every combination of values of IF statements in the program

24. We can achieve complete statement coverage but still miss bugs because:
A. The failure occurs only if you reach a statement taking the TRUE branch of an IF statement, and you got to the statement with a test that passed through the FALSE branch.
B. The failure depends on the program’s inability to handle specific data values, rather than on the program’s flow of control.
C. We are not required to test code that customers are unlikely to execute.
D. All of the above
