Question 1

A software system checks age in order to determine which welcome screen to display. Age groups are:
Group I: 0-12
Group II; 13-18 Group III: over 18
Which of the below represent boundary values?

Accepted Answer

A correct list of boundary values for the age input should include the minimum and maximum values of each age group (0, 12, 13, 18), as well as the values just
below and above each boundary (-1, 19). Boundary value analysis is a test design technique that involves testing the values at or near the boundaries of an input
domain or output range, as these values are more likely to cause errors than values in the middle. Option A satisfies this condition, as it has all six boundary values
(-1, 0, 12, 13, 18, 19). Option B has two values from the same equivalence class (12 and 13), option C has only four boundary values (0, 12, 18, 19), and option D
has no boundary values at all. Verified References: A Study Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer, page 34.

Question 2

Which of the following statements about testing in the context of an agile (iterative- incremental) development model is correct?

Accepted Answer

In the context of agile (iterative-incremental) development models, testing is integrated into the development process and occurs continuously throughout the
lifecycle of the project. Agile testing emphasizes adaptability and the need for feedback at various stages of development.
Option C is correct because regression testing is indeed necessary whenever a new increment is added to the existing system. Agile development often involves
frequent changes and additions to the codebase, which can potentially introduce new defects into previously tested code. Regression testing ensures that new
changes have not adversely affected existing functionality.
Options A, B, and D present misconceptions about agile testing:
? A is incorrect because, in agile, all types of testing (unit, integration, system, acceptance) are important and occur throughout the iteration, not just unit and
acceptance tests.
? B is incorrect because agile methodologies advocate for continuous integration and testing, where development and testing activities overlap and support each
other throughout an iteration.
? D is incorrect because agile methodologies encourage a wide range of testing types, including both functional and non-functional, as well as exploratory testing,
to ensure a comprehensive quality assessment.

Question 3

Which of the following statements about Experience Based Techniques (EBT) is correct?

Accepted Answer

Experience based techniques (EBT) are techniques that use the knowledge, intuition and skills of the test engineers to design and execute tests. EBT use tests
derived from the test engineers’ previous experience with similar technologies, domains, applications or systems. EBT are not based on the ability of the test
engineer to implement various testing techniques, but rather on their personal judgment and creativity. EBT are not done as a second stage of testing, after nonexperience-based testing took place, but rather as a complementary or alternative approach to other techniques. EBT require broad and deep knowledge in both
testing and the application or technological domain, as this can help the test engineer identify potential risks, scenarios or defects. Verified References: [A Study
Guide to the ISTQB® Foundation Level 2018 Syllabus - Springer], Chapter 5, page 48-49.

Question 4

Which of the following BEST describes a benefit of test automation?

Accepted Answer

Test automation provides numerous benefits to software testing, and one of the key advantages is the reduction of repetitive manual work. This benefit is explicitly
covered in the ISTQB Foundation Level Syllabus (v4.0).
Test automation allows testers to automate repetitive tasks such as regression testing, freeing up their time to focus on more complex and exploratory testing. This
leads to improved efficiency and helps in avoiding human errors associated with repetitive tasks. Option A: "More subjective assessment" contradicts the benefit of
automation as it focuses on objectivity.

Option C: "Availability of the test automation tool vendor" is not a direct benefit of test automation, although vendor support can be valuable.
Option D: "Negligible effort to maintain the test assets" is misleading as maintaining automated tests often requires effort and attention to changes in the system
under test. Therefore, the correct answer is B (ISTQB not-for-profit association) (ISTQB). References:

Question 5

Which of the following applications will be the MOST suitable for testing by Use Cases

Accepted Answer

A new navigation system compared with a previous system is the most suitable application for testing by use cases, because it involves a high level of interaction
between the user and the system, and the expected behavior and outcomes of the system are based on the user’s needs and goals. Use cases can help to
specify the functional requirements of the new navigation system, such as the ability to enter a destination, select a route, follow the directions, receive alerts, etc.
Use cases can also help to compare the accuracy and usability of the new system with the previous system, by defining the success and failure scenarios, the
preconditions and postconditions, and the alternative flows of each use case. Use cases can also help to design and execute test cases that cover the main and
exceptional paths of each use case, and to verify the satisfaction of the user’s expectations.
The other options are not the most suitable applications for testing by use cases, because they do not involve a high level of interaction between the user and the
system, or the expected behavior and outcomes of the system are not based on the user’s needs and goals. A billing system used to calculate monthly charge
based on a large number of subscriber parameters is more suitable for testing by data-driven testing, which is a technique for testing the functionality and
performance of a system or component by using a large set of input and output data. The ability of an antivirus package to detect and quarantine a new threat is
more suitable for testing by exploratory testing, which is a technique for testing the functionality and security of a system or component by using an informal and
flexible approach, based on the tester’s experience and intuition. The suitability and performance of a multimedia (audio video based) system to a new operating
system is more suitable for testing by compatibility testing, which is a technique for testing the functionality and performance of a system or component by using
different hardware, software, or network environments. References = CTFL 4.0 Syllabus, Section 3.1.1, page 28-29; Section 4.1.1, page 44-45; Section 4.2.1,

Question 6

Which of the following software development models BEST exemplifies a model that does NOT support the principle of early testing?

Accepted Answer

The Waterfall model exemplifies a software development model that does not support the principle of early testing. In the Waterfall model, each phase must be
completed before the next begins, which delays testing until after the completion of the earlier phases like requirements gathering and design. This can often result
in finding defects later in the development cycle, making them more expensive and time-consuming to fix (ISTQB not-for-profit association) (ISTQB not-for-profit
association).References:

Question 7

Which of the following definitions is NOT true?

Accepted Answer

Test Management tools are designed to support the planning, execution, and monitoring of the testing process. They provide features for managing test cases, test
runs, tracking defects, and reporting on testing activities. However, the statement in option C describes Test Management tools as monitoring and reporting on the
system's behavior during testing activities, which is not accurate. Test Management tools focus on the testing process itself rather than on the behavior of the
system under test.
? Test data preparation tools (A) indeed create and manage test data for use during test execution.
? Test execution tools (B) automate the execution of test cases and the comparison of actual outcomes against expected results.
? Test comparators (D) are tools that compare actual outcomes with expected outcomes, highlighting discrepancies.
Therefore, option C is the correct answer as it inaccurately describes the function of Test Management tools.

Question 8

A program is used to control a manufacturing line (turn machines on and off. start and stop conveyer belts, add raw materials to the flow. etc.). Not all actions are
possible at all times. For example, there are certain manufacturing stages that cannot be stopped - unless there is an emergency. A tester attempts to evaluate if
all such cases (where a specific action is not allowed) are covered by the tests.
Which coverage metric will provide the needed information for this analysis?

Accepted Answer

Branch coverage is a type of structural coverage metric that measures the percentage of branches or decision outcomes that are executed by the test cases. A
branch is a point in the code where the control flow can take two or more alternative paths based on a condition. For example, an if-else statement is a branch that
can execute either the if-block or the else-block depending on the evaluation of the condition. Branch coverage ensures that each branch is taken at least once by
the test cases, and thus reveals the behavior of the software under different scenarios. Branch coverage is also known as decision coverage or all-edges
coverage.
Branch coverage is suitable for testing the cases where a specific action is not allowed, because it can verify that the test cases cover all the possible outcomes of
the conditions that determine the action. For example, if the program has a condition that checks if the manufacturing stage can be stopped, then branch coverage
can ensure that the test cases cover both the cases where the stage can be stopped and where it cannot be stopped. This way, branch coverage can help identify
any missing or incorrect branches that may lead to undesired or unsafe actions.
The other options are not correct because they are not suitable for testing the cases where a specific action is not allowed. Code coverage is a general term that
encompasses various types of coverage metrics, such as statement coverage, branch coverage, data flow coverage, etc. Code coverage does not specify which
type of coverage metric is used for the analysis. Data flow coverage is a type of structural coverage metric that measures the percentage of data flow paths that
are executed by the test cases. A data flow path is a sequence of statements that define, use, or kill a variable. Data flow coverage is useful for testing the
correctness and completeness of the data manipulation in the software, but not for testing the conditions that determine the actions. Statement coverage is a type
of structural coverage metric that measures the percentage of statements or lines of code that are executed by the test cases. Statement coverage ensures that
each statement is executed at least once by the test cases, but it does not reveal the behavior of the software under different scenarios. Statement coverage is a
weaker criterion than branch coverage, because it does not account for the branches or decision outcomes in the code. References = ISTQB Certified Tester

Question 9

A calculator software is used to calculate the result for 5+6. The user noticed that the result given is 6.
This is an example of;

Accepted Answer

According to the ISTQB Glossary of Testing Terms, Version 4.0, 2018, page 18, a failure is “an event in which a component or system does not perform a
required function within specified limits”. In this case, the calculator software does not perform the required function of calculating the correct result for 5+6 within
the specified limits of accuracy and precision. Therefore, this is an example of a failure.
The other options are incorrect because:
? A mistake is “a human action that produces an incorrect result” (page 25). A mistake is not an event, but an action, and it may or may not lead to a failure. For
example, a mistake could be a typo in the code, a wrong assumption in the design, or a misunderstanding of the requirement.
? A fault is “a defect in a component or system that can cause the component or system to fail to perform its required function” (page 16). A fault is not an event,
but a defect, and it may or may not cause a failure. For example, a fault could be a logical error in the code, a missing specification in the design, or a contradiction
in the requirement.
? An error is “the difference between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition”
(page 15). An error is not an event, but a difference, and it may or may not result in a failure. For example, an error could be a rounding error in the calculation, a
measurement error in the observation, or a deviation error in the condition.

Question 10

ST is a Software Testing organization which utilizes a testing knowledge base. Access to ST knowledge base can be either full or limited. Access level is
determined based on ST certification and testing experience as follows:
* 1. If ST certified, with less than 5 years testing experience - allow limited access
* 2. If ST certified, 5-10 years of testing experience - allow full access
* 3. If not ST certified with 5-10 years of testing experience - allow limited access.
What would be the results for:
A - ST certified. 12 years of testing experience
B - Not ST certified. 7 years of testing experience
C - Not ST certified. 3 years of testing experience

Accepted Answer

The correct answer can be derived by applying the given rules to each case:
? A is ST certified and has 12 years of testing experience, which is more than 10 years. Therefore, A does not match any of the rules and the result is unknown.
? B is not ST certified and has 7 years of testing experience, which is between 5 and 10 years. Therefore, B matches rule 3 and the result is limited access.
? C is not ST certified and has 3 years of testing experience, which is less than 5 years. Therefore, C does not match any of the rules and the result is unknown.
