Introduction
Purpose of this document
The sample questions, answer sets and associated justifications in this document have been
created by a team of Subject Matter Experts and experienced question writers with the aim
of assisting ISTQB® Member Boards and Exam Boards in their question writing activities.
These questions cannot be used as-is in any official examination, but they should serve as
guidance for question writers. Given the wide variety of formats and subjects, these sample
questions should offer many ideas for the individual Member Boards on how to create good
questions and appropriate answer sets for their examinations.
Instructions
The question and answer sets are organized in the following way:
 Learning Objective and K-level
 Question - including any scenario followed by the question stem (The question is
contained in a separate document)
 Answer Set (The answer set is contained in the document)
 Correct answer – including justification of the answers

1. a, b a) is right as the Epic could be easily transferred to a storyboard as a
visual representation of the system.
b) is right as the Epic could also be easily transferred to a story
mapping.
c) is wrong as there are not enough different users of the system to use
personas to improve quality.
d) is wrong as the epic is not big enough to use diagrams and there is
nothing mentioned that diagrams are already in use.
e) is wrong as the Epic is not big enough (e.g. number of stakeholders
or interfaces, etc.)
ATT-1.1.1-1 K4 3
2. b, d
a) Wrong, because a ‘Storyboard’ is neither the ‘Agile task board’ nor the
‘Agile user story board’
b) RIGHT, because Syllabus says ‘Visualize groups of user stories
related to a common area of the system (Themes) which can be
considered for inclusion in the same iteration, as they will likely be
touching the same piece of code’
c) Wrong, because fancy answer
d) RIGHT because Syllabus says ‘Assist with identifying acceptance
criteria for user stories and epics.
ATT-1.1.1-2 K2 1
3. a a) is right as the acceptance criteria are following the INVEST criteria.
b) is wrong as the acceptance criteria are following the INVEST criteria.
c) is wrong as the scope is not as big as the scope of an Epic could be.
d) is wrong as not always are non-functional acceptance criteria
needed

5. a a) CORRECT according to Syllabus 2.1.1.,
b) Wrong because unit test can not be derived from use cases.
c) Wrong during refactoring unit test must not change to ensure same
system behaviour
d) Wrong because unit test should be written in an “atomic” manner
ATT-2.1.1-2 K2 1
6. d a) Write additional test classes to test also other relevant aspects of the
leap year calculation .
b) Start to write code that covers other relevant aspects of the leap year
calculation.
c) Start to write code that makes fail this test case.
d) Start to write code that makes pass this test case.
In TDD you should write first test code for one special area, then
write code that makes pass this test case. Then you should continue
with the next small part.Therefore, D is right and all other answers
are wrong
ATT-2.1.1 K3 2
7. b
a) Wrong
b) RIGHT because Syllabus says: ‘FIRST = Fast, Isolated, Repeatable,

8. a a) is right as it fulfills all requirements of the Gherkin language.
b) Is wrong as there is an else that is not Gherkin format
c) Is wrong as there are not enough details to develop and test this
spec.
d) Is wrong as the Given element of gherkin is missing.
ATT-2.1.2 K3 2
9. b
a) NOT correct, because related to (B) ‘Automated Test Suites’ are less
used. But Automated Testing is key to get reliable feedback in each
of the 4 week iterations.
b) CORRECT, because ‘Automated Test Suites’ are used to maximum
degree, to generate reliable feedback in each of the 4 week
iterations. Also ‘Specification based manual testing’ is used to
maximum degree to cover critical features (not covered by
automated tests). Manual Exploratory Testing is used in addition
only.
c) NOT correct, because related to (B) Manual Exploratory Testing
dominates which is not adequate for testing a safety critical
system.
d) NOT correct, because related to (B) ‘Automated Test Suites’ are
used less, so manual testing dominates, which is suboptimal
for testing in a incremental-4-week iteration development
approach
ATT-2.2.1 K4 3
10. a a) Is right as mentioned in table 1 on page 17 of the syllabus.
b) Is wrong as non-functional tests are not mentioned in the syllabus.
c) Is wrong as we are in a mission and safety critical system and risk
level is high (see syllabus page 17, table 1).
d) Is wrong as we are in a mission and safety critical system and risk
level is high (see syllabus page 17, table 1).

11. a a) is CORRECT according to Syllabus 2.2.2.
b) Wrong, Using test charters in exploratory testing is used when a
heuristic approach for writing and performing test sessions is
needed.
c) Wrong, exploratory testing shall also create insight into better test
design, ideas for testing the product, ideas for improvement and so
on.
d) Wrong because a test basis to measure the coverage, does not exist
in a quality good enough and a linkage between specification and
test is hard to define
ATT-2.2.2-2 K2 1
12. a a) CORRECT
b) The reason is not correct, although the fact stated is (we are unable
to aintain writing detailed test cases in short iterations), nor are the
benefits listed.
c) Refactoring in general, is a way to clean up code in an efficient and
controlled manner, by clarifying and simplifying the design of existing
code, without changing its behavior. It is not specificaly designed for
test cases or testing, but is used by testers on their test cases for
similar reasons.
d) The process idenfiyed in the question is not correct. the correct
process steps are: Identification, Analysis of impact, Refactor
(Mutate), Re-Run, Evaluate.

ATT-3.1.3-1 K2 1
16. a
a) RIGHT because Syllabus says: ‘an increased proportion of automated
test coverage often leads to a greater degree of manual testing that
follows reactive strategies since many of the tests that can be
prepared upfront will be automated’
b) Wrong
c) Wrong
d) Wrong
ATT-3.1.3-2 K2 1
17. a a) CORRECT answer
b) UT automation is indeed critical, but does not cover most of the code
quality in agile projects. One must include also integration level test
automation, and system level one and some manual tests has added
value as well (done mainly as exploratory tests).
c) Test Development time is the correct answer, and not Deployment
time.
d) Test Execution Time is a challenge of course, as increasing the test
suite volume every sprint, creates a load of tests needed to be run
and tested.
