Important consequences of the impossibility of complete testing are:

  1. We can never be certain that the program is bug free.
  2. We have no definite stopping point for testing, which makes it easier for some managers to argue for very little testing.
  3. We have no easy answer for what testing tasks should always be required, because every task takes time that could be spent on other high importance tasks.
  4. All of the above

Answer(s): D



Which of the following statements are true?

(i) Defects are likely to be found earlier in the development process by using reviews rather than static analysis.
(ii) Walkthroughs require code but static analysis does not require code.
(iii) Informal reviews can be performed on code and specifications.
(iv) Dynamic techniques are generally used before static techniques.
(v) Dynamic techniques can only be used after code is ready to be executed.

  1. (i), (ii), (vi).
  2. (ii), (iii), (v).
  3. (i), (iv), (v).
  4. (i), (iii), (v).

Answer(s): D

Explanation:

The other answers are incorrect because:
(ii) Walkthroughs do not require code and static analysis does require code.
(iv) Static techniques do not execute the code and therefore can be run before and after the code is ready for execution.



A bug or defect is:

  1. A mistake made by a person;
  2. A run-time problem experienced by a user;
  3. The result of an error or mistake;
  4. The result of a failure, which may lead to an error?

Answer(s): C



Which of the following are the most important factors to be taken into account when selecting test techniques?

(i) Tools available.
(ii) Regulatory standards.
(iii) Experience of the development team.
(iv) Knowledge of the test team.

The need to maintain levels of capability in each technique.

  1. (i) and (ii)
  2. (ii) and (iv)
  3. (iii) and (iv)
  4. (i) and (v)

Answer(s): B

Explanation:

Answer (i) looks temptingly right, and the availability of tools might make the use of a technique more or less attractive, but it would not be decisive in the way that regulatory standards and tester knowledge are.
Answer (iii) is irrelevant because testing should be independent of development anyway, but it could tempt someone who is unsure about the relationship between development and testing.
Answer (v) is a factor in managing the test team, and experience would need to be maintained, but this should not influence the selection of techniques for a live project.
