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. Is the entry criteria clearly defined for each activity?
iii. Is 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?
a) 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.
b) 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.
c) Point iii) of the checklist has been violated as it is not clear what marks the review as
completed.
d) Point i) of the checklist has been violated because it is not clear who is providing the
checklist for the invitation to the review.
Select ONE option.

What is checklist-based testing?
a) A test technique in which tests are derived based on the tester's knowledge of past faults,
or general knowledge of failures.
b) Procedure to derive and/or select test cases based on an analysis of the specification,
either functional or non-functional, of a component or system without reference to its
internal structure.
c) An experience-based test technique whereby the experienced tester uses a list of items to
be noted, checked, or remembered, or a set of rules or criteria against which a product has
to be verified.
d) An approach to testing where the testers dynamically design and execute tests based on
their knowledge, exploration of the test item and the results of previous tests.
Select ONE option.
Which one of the following options is categorized as a black-box test technique?

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.”

a) The statement is true. Any single test case provides 100% statement coverage and
therefore 50% decision coverage.
b) The statement is true. Any single test case would cause the outcome of the “if” statement to
be either true or false.
c) The statement is false. A single test case can only guarantee 25% decision coverage in this
case.
