Question 1

Your company produces electric windows and corresponding control units. The newest control unit for electric windows has repeatedly been problematic, which you think result from issues In the requirements, in particular, you noticed Bee following requirements in your first review.

Which of the following requirements for the system test violates at least one of the quality criteria of the ISO/IEC/IEEE 29148:2011 ?

ID; 12. When the central lock is activated, then all windows are automatically closed.

ID; 37 Given: the ignition q activated. When the button tor a window is pressed down, then the window moves down.

ID; 85: Given: the window moves up. When the window encounters resistance, then the window ttng motor stops.

ID; 142; Given: a door is open When the button for a window is pressed then the message M-85 is sent to the control unit

AThe requirement 85 is not atomic

BThe requirement 37 is Inconsistent on system level.

CThe requirement 12 is ambiguous.

DThe requirement 142 is not verifiable on system level

Answer : D

Question 2

Which statement regarding requirements-based testing is true?

ARequirements-based testing can be combined with other lest practices or testing techniques.

BRequirements-based testing can solve issues like complete requirements

COnly extensive and delated requirements can be covered completely by the tester.

DRequirements-based testing is a testing technique

Answer : D

Question 3

Which statement characterizes back-to-back testing?

ABack-to-back testing is a variation of pair programming in which the testers should sit back to back to be able to work as independently as possible from each other.

BBack-to-back testing compares test objects with mainly overlapping requirements to recognize the results of requirement change.

CBack-to-back testing compares lest objects which are based on the same requirements.

DBack-to-back testing compares different execution environments of the same test object

Answer : C

Question 4

ISO 26262 recognizes several context factors which influence the selection of testing techniques. Which statement is correct? Please choose the BEST POSSIBLE answer.

AAn testing techniques are always applied to one test basis. The specific techniques, e.g. equivalence partition analysis, however, can always be applied.

BISO 26262 recommends specific testing techniques depending on the ASH level. Furthermore, the current state of technology must be considered

CThe risk assessment provides insights regarding the risks, whose causes will then be tested Intensively (independent of the testing technique).

DFor the selection and the applicability of the test techniques, the test basis is important, but not fie test level.

Answer : B

Question 5

You are working as a .module tester* (syn. unit tester, component tester) in an automotive project for the development of a control unit for an electric window. During white-box lest design, you come atomic requirements: B1 AND (B2 OR B3). The task for you is to design test cases according to the principle of the modified condition/decision testing (MOOC). You have already designed three test cases:

1) B1 = TRUE, B2 = TRUE, B3 = FALSE

2) B1 = TRUE, B2 = FALSE, B3 = TRUE

3) B1 = FALSE, B2 = TRU, B3 = FALSE

Which of the following test cases is necessary to achieve 100% modified condition/decision coverage?

AB1 = FALSE, 62 = FALSE, B3 = TRUE

BB1 = FALSE, B2 = FALSE, B3 = FALSE

CB1= TRUE, B2 = TRUE. B3 = TRUE

DB1 = TRUE, B2 = FALSE, B3 = FALSE
