Question (1 Point)

You will be invited to a review. The work product to be reviewed is a description of the in-house document creation process. The aim of the description is to present the work distribution between the different roles involved in the process in a way that can be clearly understood by everyone.

You will be invited to a checklist-based review. The checklist will also be sent to you. It includes the following points:

i. Is the person who performs the activity clearly identified for each activity?

ii. Are the entry criteria clearly defined for each activity?

iii. Are the exit criteria clearly defined for each activity?

iv. Are the supporting roles and their scope of work clearly defined for each activity?

In the following we show an excerpt of the work result to be reviewed, for which you should use the checklist above:

“After checking the customer documentation for completeness and correctness, the software architect creates the system specification. Once the software architect has completed the system specification, he invites testers and verifiers to the review. A checklist describes the scope of the review. Each invited reviewer creates review comments – if necessary – and concludes the review with an official review done-comment.”

Which of the following statements about your review is correct?

Select ONE option.

Point ii) of the checklist has been violated because it is not clear which condition must be fulfilled in order to invite to the review

You notice that in addition to the tester and the verifier, the validator must also be invited. Since this item is not part of your checklist, you do not create a corresponding comment

Point iii) of the checklist has been violated as it is not clear what marks the review as completed

Point i) of the checklist has been violated because it is not clear who is providing the checklist for the invitation to the review

10.

Question (1 Point)

Which of the following statements correctly describes the difference between testing and debugging?

Select ONE option.

Testing identifies the source of defects; debugging analyzes the defects and proposes prevention activities

Dynamic testing shows failures caused by defects; debugging eliminates the defects, which are the source of failures

Testing does not remove faults; but debugging removes defects that cause the faults

Dynamic testing prevents the causes of failures; debugging removes the failures

11.

Question (1 Point)

The following statement refers to decision coverage:

“When the code contains only a single ‘if’ statement and no loops or CASE statements, and its execution is not nested within the test, any single test case we run will result in 50% decision coverage.”

Which of the following statement is correct?

Select ONE option.

The statement is true. Any single test case provides 100% statement coverage and therefore 50% decision coverage

The statement is true. Any single test case would cause the outcome of the “if” statement to be either true or false

The statement is false. A single test case can only guarantee 25% decision coverage in this case

The statement is false. The statement is too broad. It may be correct or not, depending on the tested software

12.
