The objective of testing is to implement exhaustive testing and execute as many test cases as possible.

Exhaustive testing can only be carried out using behavior-based techniques.

It is impossible to test all possible combinations of inputs and preconditions of a system.

Automated testing enables exhaustive testing.

Q161. Which ONE of the following options isNOTa benefit oftest automation?

Reduced test execution times

More objective assessment

Prevention of simple human errors

Eliminating completely the need for manual testing

Q162. Which testing principle provides a good reason to base testing upon risk mitigation priorities?

Testing shows the presence of defects

Exhaustive testing is impossible

Tests wear out

Defects tend to cluster in a few modules

Q163. Which of the following is not an example of a typical generic skill required for testing?

Be able to apply test-driven development

Be able to use test management tools and defect tracking tools

Be able to communicate defects and failures to developers as objectively as possible

Possess the necessary social skills that support effective teamwork

Test-driven development is not an example of a typical generic skill required for testing, but rather an example of a specific technical skill or a development practice that may or may not be relevant for testing, depending on the context and the objectives of the testing activities. Test-driven development is an approach to software development and testing, in which the developers write automated unit tests before writing the source code, and then refactor the code until the tests pass. Test-driven development can help to improve the quality, the design, and the maintainability of the code, as well as to provide fast feedback and guidance for the developers. However, test-driven development is not a skill that is generally expected or needed for testers, especially for testers who are not involved in unit testing or who do not have access to the source code. The other options are examples of typical generic skills required for testing, which are skills that are applicable and beneficial for testing in any context or situation, regardless of the specific testing techniques, tools, or methods used. The typical generic skills required for testing include:
* Be able to use test management tools and defect tracking tools: These are tools that help testers to plan, organize, monitor, and control the testing activities and resources, as well as to record, track, analyze, and resolve the defects detected during testing. These tools can improve the efficiency, the effectiveness, and the communication of the testing process, as well as to provide traceability, metrics, and reports for the testing outcomes.
* Be able to communicate defects and failures to developers as objectively as possible: This is a skill that involves the ability to report and describe the defects and failures found during testing in a clear, concise, accurate, and unbiased manner, using relevant information, evidence, and terminology, without making assumptions, judgments, or accusations. This skill can facilitate the collaboration, the understanding, and the resolution of the defects and failures between the testers and the developers, as well as to prevent conflicts, misunderstandings, or blame games.
* Possess the necessary social skills that support effective teamwork: These are skills that involve the ability to interact, cooperate, and coordinate with other people involved in or affected by the testing activities, such as the test manager, the test team, the project manager, the developers, the customers, the users, etc. These skills can include communication, negotiation, leadership, motivation, feedback, conflict resolution, etc. These skills can enhance the quality, the productivity, and the satisfaction of the testing process, as well as to foster a positive and constructive testing culture.

Q164. A requirement specifies that if the total amount of sales (TAS) made during the year by a corporate seller is
300000€ or more, the bonus that must be paid to the seller is 100% of a certain amount agreed upon at the beginning of the year. The software contains a fault as it implements this requirement with the decision “IF (TAS = 300000)” instead of “IF (TAS >= 300000)”. The application of the 3-value boundary value analysis to this problem consists of the following three test cases (TAS is an integer variable):
TC1 = 299999 TC2=300000 TC3=300001
Which of the following statements is true?

TC1 would highlight the fault

TC2 would highlight the fault

TC3 would highlight the fault

None of the three test cases would highlight the fault

The problem described involves a software implementation error in a decision statement for calculating a bonus based on the Total Amount of Sales (TAS). The requirement states that if TAS is 300,000 or more, a bonus should be paid. However, the software incorrectly implements this with “IF (TAS = 300000)” instead of “IF (TAS >= 300000)”.
Applying Boundary Value Analysis (BVA) to this situation involves selecting test cases at the boundaries of the input domain, including just below, at, and just above the boundary conditions.
* Test Case TC1 = 299999:
* This value is just below the boundary (300,000).
* Expected Result: No bonus should be paid.
* Actual Result: No bonus paid.
* TC1does not highlight the fault because the implemented condition “IF (TAS = 300000)” and the correct condition “IF (TAS >= 300000)” both yield the same result (no bonus).
* Test Case TC2 = 300000:
* This value is exactly at the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: Bonus paid.
* TC2does not highlight the fault because the implemented condition “IF (TAS = 300000)” and the correct condition “IF (TAS >= 300000)” both yield the same result (bonus paid).
* Test Case TC3 = 300001:
* This value is just above the boundary.
* Expected Result: Bonus should be paid.
* Actual Result: No bonus paid due to the incorrect implementation.
* TC3highlights the fault because the implemented condition “IF (TAS = 300000)” fails to pay the bonus, whereas the correct condition “IF (TAS >= 300000)” would pay the bonus.
* BVA focuses on the edges of input ranges where errors are more likely.
* The critical values are just below, at, and just above the boundary.
Boundary Value Analysis (BVA):Verification:According to the ISTQB CTFL syllabus, BVA is an essential technique for identifying potential errors at the boundaries of input ranges. This is because developers are more likely to make mistakes at these extremes.
Therefore,TC3 (300001)is the test case that would highlight the fault in the software’s implementation of the decision condition.

Q165. Categorize these risks into project risks and product risks.
(i) Unforeseen technical difficulties, such as integrating with third-
party APIs for payment or delivery tracking, could slow down progress
(ii) Sensitive customer information, such as payment details and
addresses, may be exposed due to insufficient security measures
(iii) Uncontrolled additional feature requests or unclear requirements
may lead to delays and budget overruns
(iv) Limited availability of skilled developers, testers, or designers
could hinder the timely delivery of the product

[II]. A development vendor fails to deliver their software system on time, causing significant delays to system integration testing activities that have been planned as part of a development project for a system of systems
[III]. People in the test team do not have sufficient skills to automate tests at the test levels required by the test automation strategy which does not allow production of an effective regression test suite
[IV]. In a web application, data from untrusted sources is not subject to proper input validation, making the application vulnerable to several security attacks Which of the following statements is true?

[I] and [III] are product risks; [II] and [IV] are project risks

[I] and [IV] are product risks. [II] and [III] are project risks

Q169. You test a hotel booking system and you identified three domains, each with three equivalence partitions:
– Number of guests. Partitions:
– (G1) single guest
– (G2) couple
– (G3) group
– Room type. Partitions:
– (R1) standard
– (R2) deluxe
– (R3) suite
– Booking duration. Partitions:
– (D1) 1-2 nights
– (D2) 3-6 nights
– (D3) 7 or more nights
The hotel booking policy has some constraints, which are controlled by the reservation system, so your test cases cannot violate them. The constraints are:
– Group booking (G3) cannot be made in standard rooms (R1).
– Suite room (R3) cannot be booked for short stays of 1 or 2 nights
(D1)
– Single guests (G1) cannot book deluxe room (R2) for long stays of 7
or more nights (D3)
A test case contains the number of guests, the room type, and the booking duration. You apply equivalence partitioning when designing the test cases.
What is the MINIMAL number of test cases to achieve Each Choice coverage?

Q170. In a two-hour uninterrupted test session, performed as part of an iteration on an Agile project, a heuristic checklist was used to help the tester focus on some specific usability issues of a web application.
The unscripted tests produced by the tester’s experience during such session belong to which one of the following testing quadrants?

The unscripted tests produced by the tester’s experience during the two-hour test session belong to the testing quadrant Q3. The testing quadrants are a classification of testing types based on two dimensions: the test objectives (whether the testing is focused on supporting the team or critiquing the product) and the test basis (whether the testing is based on the technology or the business). The testing quadrants are labeled as Q1, Q2, Q3, and Q4, and each quadrant represents a different testing perspective, such as unit testing, acceptance testing, usability testing, or performance testing. The testing quadrant Q3 corresponds to the testing types that have the objective of critiquing the product from the business perspective, such as exploratory testing, usability testing, user acceptance testing, alpha testing, beta testing, etc. The unscripted tests performed by the tester in the given scenario are examples of exploratory testing and usability testing, as they are based on the tester’s experience, intuition, and learning of the web application, and they focus on some specific usability issues, such as the user interface, the user satisfaction, the user feedback, etc. The other options are incorrect, because:
The testing quadrant Q1 corresponds to the testing types that have the objective of supporting the team from the technology perspective, such as unit testing, component testing, integration testing, system testing, etc. These testing types are usually performed by developers or testers who have access to the source code, the design, the architecture, or the configuration of the software system, and they aim to verify the functionality, the quality, and the reliability of the software system at different levels of integration.
The testing quadrant Q2 corresponds to the testing types that have the objective of supporting the team from the business perspective, such as functional testing, acceptance testing, story testing, scenario testing, etc. These testing types are usually performed by testers or customers who have access to the requirements, the specifications, the user stories, or the business processes of the software system, and they aim to validate that the software system meets the expectations and the needs of the users and the stakeholders.
The testing quadrant Q4 corresponds to the testing types that have the objective of critiquing the product from the technology perspective, such as performance testing, security testing, reliability testing, compatibility testing, etc. These testing types are usually performed by testers or specialists who have access to the tools, the metrics, the standards, or the benchmarks of the software system, and they aim to evaluate the non-functional aspects of the software system, such as the efficiency, the security, the reliability, or the compatibility of the software system under different conditions or environments.

grant a license
– 17 years old, passed vision test, failed driving test; expected
result: do not grant a license
– 19 years old, failed both vision and driving tests; expected result:
do not grant a license
Which test case needs to be added to this set to achieve full decision table coverage?

No test case is needed; the existing test cases already achieve the required coverage

17 years old, passed both vision and driving test; expected result: grant a license

18 years old, passed vision test, failed driving test; expected result: do not grant a license

20 years old failed vision test passed driving test-expected result: do not grant a license
