  Which type of test tool would you recommend for this purpose?

  A. Test execution tool

  B. Modeling tool

• Question 87:

  Which of the following statements correctly emphasize the viewpoint of a developer and a tester with respect to the testing psychology?

  A. If a developer implements a fundamental design error (e.g. conceptual misunderstanding), it is HIGHLY probable that he/she will not find is using own tests.

  II. The tester can observe the object to be tested without prejudices. It is not his/her own product and the assumptions and misunderstandings of the developer are not, in general, the same as those of the tester.

  III. An independent tester must acquire knowledge about the object to be tested in order to create test cases; the developer has good knowledge of the object to be tested and this saves time: hence, it is advisable to assign the test activities to the developer

  IV. The weakness of the tests done by the developer is that developers tend to be optimistic about their own software. The risk is that reasonable test cases are forgotten because the developer is more interested in development than testing.

  B. I, II, III

  C. I, II, IV

  D. I, II

  E. III, IV

  Correct Answer: D

• Question 88:

  B. Assessment of whether the benefits will be achieved at reasonable cost

  C. Highlight where, if necessary, changes should be made to the test process

  D. Identify rules and conventions that should be defined for the extensive use of the tool

  Correct Answer: D

• Question 89:

  A software application is supposed to calculate square root of all integers from 1 to 32767. The tester divides the input into valid and invalid equivalence classes. Valid equivalence class: 1-32767, invalid: all negative numbers, all numbers > 32767, all non-integers etc. However, when square root for all numbers in the valid equivalence class was calculated, it was found that for 3 number, the results were incorrect. These number were not the boundary values. Which of the following is correct?

  A. It is sometimes possible to find that some values in equivalence class do not behave in the same manner as rest of the class.

  B. The tester should always try all possible.

  C. It is practically impossible for values in an equivalence class to behave in different manner.

  D. The tester chose equivalence classes incorrectly.

  Correct Answer: A

  A. 3

  B. 6

  C. Can't be determined

  D. 9

  Correct Answer: D
