NEW QUESTION # 81
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?

• A. Q3
• B. Q2
• C. Q1
• D. Q4

Answer: A

Explanation:
Explanation
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 usabilityissues, 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.

NEW QUESTION # 82
Which of the following statements is not correct?

• A. Identifying defects may be perceived as criticism against product
• B. Testing is often seen as a destructive activity instead of constructive activity
• C. Looking for defects in a system may require Ignoring system details
• D. Looking for defects in system requires professional pessimism and curiosity

Answer: C

Explanation:
* Looking for defects in a system does not require ignoring system details, but rather paying attention to them and understanding how they affect the system's quality, functionality, and usability. Ignoring system details could lead to missing important defects or testing irrelevant aspects of the system.
* Identifying defects may be perceived as criticism against product, especially by the developers or stakeholders who are invested in the product's success. However, identifying defects is not meant to be a personal attack, but rather a constructive feedback that helps to improve the product and ensure its alignment with the requirements and expectations of the users and clients.
* Looking for defects in system requires professional pessimism and curiosity, as testers need to anticipate and explore the possible ways that the system could fail, malfunction, or behave unexpectedly.
Professional pessimism means being skeptical and critical of the system's quality and reliability, while curiosity means being eager and interested in finding out the root causes and consequences of the defects.
* Testing is often seen as a destructive activity instead of constructive activity, as it involves finding and reporting the flaws and weaknesses of the system, rather than creating or enhancing it. However, testing is actually a constructive activity, as it contributes to the system's improvement, verification, validation, and optimization, and ultimately to the delivery of a high-quality product that meets the needs and expectations of the users and clients.

NEW QUESTION # 83
Which of the following statements about exploratory testing is true?

• A. In exploratory testing, testers usually produce scripted tests and establish bidirectional traceability between these tests and the items of the test basis
• B. When exploratory testing is conducted following a session-based approach, the issues detected by the testers can be documented in session sheets
• C. Exploratory testing is an experience-based test technique in which testers explore the requirements specification to detect non testable requirements
• D. Exploratory testing is an experience-based test technique used by testers during informal code reviews to find defects by exploring the source code

Answer: B

Explanation:
Exploratory testing is an experience-based test technique in which testers dynamically design and execute tests based on their knowledge, intuition, and learning of the software system, without following predefined test scripts or test cases. Exploratory testing can be conducted following a session-based approach, which is a structured way of managing and measuring exploratory testing. In a session-based approach, the testers perform uninterrupted test sessions, usually lasting between 60 and 120 minutes, with a specific charter or goal, and document the issues detected, the test coverage achieved, and the time spent in session sheets.
Session sheets are records of the test activities, results, and observations during a test session, which can be used for reporting, debriefing, and learning purposes. The other statements are false, because:
* Exploratory testing is not a test technique in which testers explore the requirements specification to detect non testable requirements, but rather a test technique in which testers explore the software system to detect functional and non-functional defects, as well as to learn new information, risks, or opportunities. Non testable requirements are requirements that are ambiguous, incomplete, inconsistent, or not verifiable, which can affect the quality and effectiveness of the testing process. Non testable requirements can be detected by applying static testing techniques, such as reviews or inspections, to the requirements specification, before the software system is developed or tested.
* Exploratory testing is not a test technique used by testers during informal code reviews to find defects by exploring the source code, but rather a test technique used by testers during dynamic testing to find defects by exploring the behavior and performance of the software system, without examining the source code. Informal code reviews are static testing techniques, in which the source code is analyzed by one or more reviewers, without following a formal process or using a checklist, to identify defects,
* violations, or improvements. Informal code reviews are usually performed by developers or peers, not by testers.
* In exploratory testing, testers usually do not produce scripted tests and establish bidirectional traceability between these tests and the items of the test basis, but rather produce unscripted tests and adapt them based on the feedback and the findings of the testing process. Scripted tests are tests that are designed and documented in advance, with predefined inputs, outputs, and expected results, and are executed according to a test plan or a test procedure. Bidirectional traceability is the ability to trace both forward and backward the relationships between the items of the test basis, such as the requirements, the design, the risks, etc., and the test artifacts, such as the test cases, the test results, the defects, etc.
Scripted tests and bidirectional traceability are usually associated with more formal and structured testing approaches, such as specification-based or structure-based test techniques, not with exploratory testing.

NEW QUESTION # 84
Consider a given test plan which, among others, contains the following three sections: "Test Scope", "Testing Communication", and "Stakeholders". The features of the test object to be tested and those excluded from the testing represent information that is:

• A. usually included in a test plan and, in the given test plan, it is more likely to be specified within
  "Stakeholders" rather than in the other two sections mentioned
• B. not usually included in a test plan, and therefore in the given test plan it should not be specified neither within the three sections mentioned, nor within the others
• C. usually included in a test plan and, in the given test plan, it is more likely to be specified within "Test Scope" rather than in the other two sections mentioned
• D. usually included in a test plan and, in the given test plan, it is more likely to be specified within "Testing Communication" rather than in the other two sections mentioned

Answer: C

Explanation:
Explanation
The features of the test object to be tested and those excluded from the testing represent information that is usually included in a test plan and, in the given test plan, it is more likely to be specified within "Test Scope" rather than in the other two sections mentioned. The test scope defines the boundaries and limitations of the testing activities, such as the test items, the features to be tested, the features not to be tested, the test objectives, the test environment, the test resources, the test assumptions, the test risks, etc. The test scope helps to establish a common understanding of what is included and excluded from the testing, and to avoid ambiguity, confusion, or misunderstanding among the stakeholders. The other two sections, "Testing Communication" and "Stakeholders", are also important parts of a test plan, but they do not directly address the features of the test object. The testing communication describes the methods, frequency, and responsibilities for the communication and reporting of the testing progress, status, issues, and results. The stakeholders identify the roles and responsibilities of the 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. References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

NEW QUESTION # 85
Which of the following statements refers to good testing practice to be applied regardless of the chosen software development model?

• A. Test objectives should be the same for all test levels, although the number of tests designed at various levels can vary significantly
• B. Involvement of testers in work product reviews should occur as early as possible to take advantage of the early testing principle
• C. Test levels should be defined such that the exit criteria of one level are part of the entry criteria for the next level
• D. Tests should be written in executable format before the code is written and should act as executable specifications that drive coding

Answer: B

Explanation:
Explanation
The statement that refers to good testing practice to be applied regardless of the chosen software development model is option D, which says that involvement of testers in work product reviews should occur as early as possible to take advantage of the early testing principle. Work product reviews are static testing techniques, in which the work products of the software development process, such as the requirements, the design, the code, the test cases, etc., are examined by one or more reviewers, with or without the author, to identify defects, violations, or improvements. Involvement of testers in work product reviews can provide various benefits for the testing process, such as improving the test quality, the test efficiency, and the test communication. The early testing principle states that testing activities should start as early as possible in the software development lifecycle, and should be performed iteratively and continuously throughout the lifecycle. Applying the early testing principle can help to prevent, detect, and remove defects at an early stage, when they are easier, cheaper, and faster to fix, as well as to reduce the risk, the cost, and the time of the testing process. The other options are not good testing practices to be applied regardless of the chosen software development model, but rather specific testing practices that may or may not be applicable or beneficial for testing, depending on the context and the objectives of the testing activities, such as:
Tests should be written in executable format before the code is written and should act as executable specifications that drive coding: This is a specific testing practice that is associated with test-driven development, which 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 good testing practice to be applied regardless of the chosen software development model, as it may not be feasible, suitable, or effective for testing in some contexts or situations, such as when the requirements are unclear, unstable, or complex, when the test automation tools or skills are not available or adequate, when the testing objectives or levels are not aligned with the unit testing, etc.
Test levels should be defined such that the exit criteria of one level are part of the entry criteria for the next level: This is a specific testing practice that isassociated with sequential software development models, such as the waterfall model, the V-model, or the W-model, in which the software development and testing activities are performed in a linear and sequential order, with well-defined phases, deliverables, and dependencies. Test levels are the stages of testing that correspond to the levels of integration of the software system, such as component testing, integration testing, system testing, and acceptance testing. Test levels should have clear and measurable entry criteria and exit criteria, which are the conditions that must be met before starting or finishing a test level. In sequential software development models, the exit criteria of one test level are usually part of the entry criteria for the next test level, to ensure that the software system is ready and stable for the next level of testing. However, this is not a good testing practice to be applied regardless of the chosen software development model, as it may not be relevant, flexible, or efficient for testing in some contexts or situations, such as when the software development and testing activities are performed in an iterative and incremental order, with frequent changes, feedback, and adaptations, as in agile software development models, such as Scrum, Kanban, or XP, when the test levels are not clearly defined or distinguished, or when the test levels are performed in parallel or concurrently, etc.
Test objectives should be the same for all test levels, although the number of tests designed at various levels can vary significantly: This is a specific testing practice that is associated with uniform software development models, such as the spiral model, the incremental model, or the prototyping model, in which the software development and testing activities are performed in a cyclical and repetitive manner, with similar phases, deliverables, and processes. Test objectives are the goals or the purposes of testing, which can vary depending on the test level, the test type, the test technique, the test environment, the test stakeholder, etc. Test objectives can be defined in terms of the test basis, the test coverage, the test quality, the test risk, the test cost, the test time, etc. Test objectives should be specific, measurable, achievable, relevant, and time-bound, and they should be aligned with the project objectives and the quality characteristics. In uniform software development models, the test objectives may be the same for all test levels, as the testing process is repeated for each cycle or iteration, with similar focus, scope, and perspective of testing. However, this is not a good testing practice to be applied regardless of the chosen software development model, as it may not be appropriate, realistic, or effective for testing in some contexts or situations, such as when the software development and testing activities are performed in a hierarchical and modular manner, with different phases, deliverables, and dependencies, as in sequential software development models, such as the waterfall model, the V-model, or the W-model, when the test objectives vary according to the test levels, such ascomponent testing, integration testing, system testing, and acceptance testing, or when the test objectives change according to the feedback, the learning, or the adaptation of the testing process, as in agile software development models, such as Scrum, Kanban, or XP, etc.References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents:

NEW QUESTION # 86
Which of the following statements is true?

• A. Testers who perform functional tests are generally expected to have more technical skills than testers who perform non-functional tests
• B. Non-functional testing includes testing of both technical and non-technical quality characteristics
• C. Functional testing focuses on what the system should do while non-functional testing on the internal structure of the system
• D. The test techniques that can be used to design white-box tests are described in the ISO/IEC 25010 standard

Answer: B

Explanation:
Explanation
Non-functional testing includes testing of both technical and non-technical quality characteristics.
Non-functional testing is the process of testing the quality attributes of a system, such as performance, usability, security, reliability, etc. Non-functional testing can be applied at any test level and can use both black-box and white-box test techniques. Non-functional testing can cover both technical aspects, such as response time, throughput, resource consumption, etc., and non-technical aspects, such as user satisfaction, accessibility, compliance, etc. Therefore, option B is the correct answer.

NEW QUESTION # 87
The following rules determine the annual bonus to be paid to a salesman of a company based on the total annual amount of the sales made (referredto as TAS).
If the TAS is between 50k€ and 80k€, the bonus is 10%. If the TAS exceeds 80k€ by a value not greater than
40k€, the bonus is 15%. Finally, if the TAS
exceeds the maximum threshold which entitles to a 15% bonus, the bonus is 22%.
Consider applying equivalence partitioning to the TAS (Note: 1k€ = 1000 euros).
Which one of the following answers contain only test cases that belong to the same equivalence partition?

• A. TC1 = 40k€; TC2= 46k€; TC3=51k€; TC4=53k€
• B. TC1 = 79k€; TC2= 80k€; TC3=81k€; TC4=82k€
• C. TC1 = 81 k€; TC2= 97k€; TC3=111k€; TC4=118k€
• D. TC1 = 90k€; TC2= 110k€; TC3=125k€: TC4=140k€

Answer: C

Explanation:
Explanation
This answer is correct because equivalence partitioning is a test design technique that divides the input domain of a system or component into partitions of equivalent data, such that each partition is expected to produce the same output or behavior. Equivalence partitioning aims to reduce the number of test cases by selecting one representative value from each partition. In this case, the input domain of the TAS can be divided into four partitions based on the bonus rules: less than 50k€, between 50k€ and 80k€, between 80k€ and 120k€, and more than 120k€. The test cases in the answer belong to the same partition, which is between 80k€ and 120k€, and they are expected to produce the same output, which is a bonus of 15%.

The acceptance criteria associated with a user story:

• A. can be written in different formats and represent an aspect of a user story referred to as confirmation' of the so called "3 C's"
• B. must be written in one of the two following formats: scenario-oriented or rule-oriented
• C. are often written in a rule-oriented format using the template referred to as "Given/When/Then"
• D. are often documented following in rule-oriented format using the following template: "As a [role], I want [feature], so that I can [benefit]"

Answer: A

Explanation:
Explanation
The acceptance criteria associated with a user story are the conditions that must be met for the user story to be considered done and to deliver the expected value to the user. They are often written in different formats, such as rule-oriented, scenario-oriented, or table-oriented, depending on the nature and complexity of the user story.They represent an aspect of a user story referred to as confirmation, which is one of the so called "3 C's" of user stories. The other two aspects are card and conversation. Card refers to the concise and informal description of the user story, usually following the template: "As a [role], I want [feature], so that I can
[benefit]". Conversation refers to the ongoing dialogue between the stakeholders and the team members to clarify and refine the user story and its acceptance criteria. Therefore, option C is the correct answer.

NEW QUESTION # 89
Which of the following statements about TDD, BDD and ATDD is true?

• A. ATDD is a black-box test design technique that is applicable exclusively at acceptance test level
• B. BDD is a developer practice where business stakeholders are not usually involved as the tests are directly written at unit/component test level
• C. ATDD is the practice of running the automated acceptance tests as part of a continuous integration process
• D. Refactoring is a practice that is an integral part of TDD and is applied both to tests and to code written to satisfy those tests

Answer: D

Explanation:
Test-Driven Development (TDD) includes refactoring as a key practice. After writing tests and the code to satisfy those tests, refactoring is performed to improve the code and test quality without changing the functionality. This continuous process helps maintain clean, efficient, and manageable code.

NEW QUESTION # 91
Following a risk-based testing approach you have designed 10 tests to cover a product risk with a high-risk level. You want to estimate, adopting the three-point test estimation technique, the test effort required to reduce the risk level to zero by executing those 10 tests. You made the following three initial estimates:
* most optimistic = 6 person hours
* most likely = 30 person hours
* most pessimistic = 54 person hours
Based only on the given information, which of the following answers about the three-point test estimation technique applied to this problem is true?

• A. The final estimate is between 6 person hours and 54 person hours
• B. The final estimate is exactly 30 person hours because the technique uses the initial most likely estimate as the final estimate
• C. The final estimate is between 22 person hours and 38 person hours
• D. The final estimate is exactly 30 person hours because the technique uses the arithmetic mean of the three initial estimates as the final estimate

Answer: C

Explanation:
Explanation
The three-point test estimation technique is a method of estimating the test effort based on three initial estimates: the most optimistic, the most likely, and the most pessimistic. The technique uses a weighted average of these three estimates to calculate the final estimate, which is also known as the expected value. The formula for the expected value is:
Expected value = (most optimistic + 4 * most likely + most pessimistic) / 6 Using the given values, the expected value is:
Expected value = (6 + 4 * 30 + 54) / 6 Expected value = 30 person hours However, the expected value is not the only factor to consider when estimating the test effort. The technique also calculates the standard deviation, which is a measure of the variability or uncertainty of the estimates. The formula for the standard deviation is:
Standard deviation = (most pessimistic - most optimistic) / 6
Using the given values, the standard deviation is:
Standard deviation = (54 - 6) / 6 Standard deviation = 8 person hours
The standard deviation can be used to determine a range of possible values for the test effort, based on a certain level of confidence. For example, using a 68% confidence level, the range is:
Expected value ± standard deviation
Using the calculated values, the range is:
30±8 person hours
Therefore, the final estimate is between 22 person hours and 38 person hours, which is option A.

NEW QUESTION # 92
A system has a self-diagnostics module that starts executing after the system is reset. The diagnostics are running 12 different tests on the systems memory hardware. The following is one of the requirements set for the diagnostics module:
'The time taking the diagnostics tests to execute shall be less than 2 seconds' Which of the following is a failure related to the specified requirement?

• A. The diagnostic tests fail to start after a system reset
• B. The diagnostic tests take too much time to execute
• C. The diagnostic tests fail due to incorrect implementation of the test code
• D. The diagnostic tests that measure the speed of the memory, fail

Answer: B

Explanation:
A failure is an event in which a component or system does not perform a required function within specified limits1. A requirement is a condition or capability needed by a user to solve a problem or achieve an objective2. In this case, the requirement is that the diagnostics tests should execute in less than 2 seconds. Therefore, any event that violates this requirement is a failure. The only option that clearly violates this requirement is B. The diagnostic tests take too much time to execute. If the diagnostic tests take more than 2 seconds to complete, then they do not meet the specified limit and thus fail. The other options are not necessarily failures related to the specified requirement. Option A. The diagnostic tests fail to start after a system reset is a failure, but not related to the time limit. It is related to the functionality of the self-diagnostics module. Option C. The diagnostic tests that measure the speed of the memory, fail is also a failure, but not related to the time limit. It is related to the accuracy of the memory tests. Option D. The diagnostic tests fail due to incorrect implementation of the test code is also a failure, but not related to the time limit. It is related to the quality of the test code. Reference = ISTQB® Certified Tester Foundation Level Syllabus v4.0, Requirements Engineering Fundamentals.

Which of the following is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development?

• A. Acceptance Test-Driven Development (ATDD)
• B. Test-Driven Development (TDD)
• C. Domain-Driven Design (DDD)
• D. Behavior-Driven Development (BDD)

Answer: D

Explanation:
This answer is correct because Behavior-Driven Development (BDD) is a test-first approach, where tests that express a shared understanding from stakeholders of how the application is expected to work, are first written in business-readable language (following the Given/When/Then format), and then made executable to drive development. BDD is a collaborative approach that involves testers, developers, business analysts, product owners, and other stakeholders in defining the expected behavior of the application using scenarios that describe the preconditions, actions, and outcomes of the application. BDD scenarios are written using a domain-specific language (DSL) that can be translated into executable test cases using tools such as Cucumber or SpecFlow. BDD aims to improve communication, collaboration, and feedback among the team members, and to deliver software that meets the customer's needs and expectations.

• A. 0
• B. 1
• C. 2
• D. 3

Answer: B

Explanation:
Explanation
The minimum number of test cases needed to cover every unique sequence of up to 3 states/2 transitions starting in the "Start" state and ending in the "End" state is 4. This is because there are 4 unique sequences of up to 3 states/2 transitions starting in the "Start" state and ending in the "End" state:

Start -> Deal -> End
Start -> 1st Deal -> End
Start -> 2nd Deal -> End References: ISTQB Certified Tester Foundation Level (CTFL) v4.0 sources and documents.

NEW QUESTION # 95
The tests at the bottom layer of the test pyramid:

• A. cover larger pieces of functionalities than the tests at the top layer of the pyramid
• B. are defined as 'Ul Tests' or 'End-To-End tests' in the different models of the pyramid
• C. are unscripted tests produced by experience-based test techniques
• D. run faster than the tests at the top layer of the pyramid

Answer: D

Explanation:
Explanation
The tests at the bottom layer of the test pyramid run faster than the tests at the top layer of the pyramid because they are more focused, isolated, and atomic. They usually test individual units or components of the software system, such as classes, methods, or functions. They are also easier to maintain and execute, as they have fewer dependencies and interactions with other parts of the system. The tests at the top layer of the test pyramid, on the other hand, are slower because they cover larger pieces of functionalities, such as user interfaces, workflows, or end-to-end scenarios. They also have more dependencies and interactions with other systems, such as databases, networks, or external services. They are more complex and costly to maintain and execute, as they require more setup and teardown procedures, test data, and test environments. References:

NEW QUESTION # 96
A typical objective of testing is to ensure that:

• A. testing is used to drive the development of a software
• B. a software has been tested using a combination of test techniques
• C. there are no defects in a software that is about to be released
• D. a software has been properly covered

Answer: B

Explanation:
This answer is correct because a typical objective of testing is to ensure that a software has been tested using a combination of test techniques, such as black-box, white-box, or experience-based techniques, that are appropriate for the test objectives, test levels, and test types. Testing using a combination of test techniques can increase the effectiveness and efficiency of testing, as different techniques can target different aspects of the software quality, such as functionality, usability, performance, security, reliability, etc. Testing using a combination of test techniques can also reduce the risk of missing defects that could be detected by one technique but not by another.

NEW QUESTION # 97
Consider the following examples of risks identified in different software development projects:
[I]. The contrast color ratio for both normal text and large text of a website does not comply with the applicable accessibility guidelines, making it difficult for many users to read the content on the pages
[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?

• A. [I] and [III] are product risks; [II] and [IV] are project risks
• B. [I] and [IV] are product risks. [II] and [III] are project risks
• C. [II], [III] and [IV] are product risks; [I] is a project risk
• D. [IV] is a product risk; [I]. [II] and [III] are project risks

Answer: B

Explanation:
This answer is correct because product risks are risks that affect the quality of the software product, such as defects, failures, or non-compliance with requirements or standards. Project risks are risks that affect the project's schedule, budget, resources, or scope, such as delays, cost overruns, skill gaps, or scope changes. In this case, [I] and [IV] are product risks, as they relate to the accessibility and security of the software product, which are quality attributes. [II] and [III] are project risks, as they relate to the delivery time and the test automation skills of the test team, which are project factors.

NEW QUESTION # 98
The following 4 equivalence classes are given:

Which of the following alternatives includes correct test values for x. based on equivalence partitioning?

• A. -99; 99:101; 1001
• B. -100; 100:1000; 1001
• C. -1000; -100; 100; 1000
• D. -500; 0; 100; 1000

Answer: C

Explanation:
The question is about selecting the correct test values for x based on equivalence partitioning. Equivalence partitioning is a software test design technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In this case, the given equivalence classes are:
(x \leq -100)
(-100 < x < 100)
(100 \leq x < 1000)
(x \geq 1000)
Option D provides a value from each of these partitions:
For (x \leq -100), it gives -1000.
For (-100 < x < 100), it gives -100 and 100.
For (100 \leq x < 1000), it gives 500.
For (x \geq 1000), it gives 1500.
So, option D covers all four given equivalence classes with appropriate values.

NEW QUESTION # 99
Which of the following statements about how different types of test tools support testers is true?

• A. The support offered by a bug prediction tool is often used by testers to track the bugs they found
• B. The support offered by a performance testing tool is often leveraged by testers to run load tests
• C. The support offered by a test data preparation tool is often leveraged by testers to run automated regression test suites
• D. The support offered by a continuous integration tool is often leveraged by testers to automatically generate test cases from a model

Answer: B

Explanation:
The support offered by a performance testing tool is often leveraged by testers to run load tests, which are tests that simulate a large number of concurrent users or transactions on the system under test, in order to measure its performance, reliability, and scalability. Performance testing tools can help testers to generate realistic workloads, monitor system behavior, collect and analyze performance metrics, and identify performance bottlenecks. The other statements are false, because:
A test data preparation tool is a tool that helps testers to create, manage, and manipulate test data, which are the inputs and outputs of test cases. Test data preparation tools are not directly related to running automated regression test suites, which are test suites that verify that the system still works as expected after changes or modifications. Regression test suites are usually executed by test execution tools, which are tools that can automatically run test cases and compare actual results with expected results.
A bug prediction tool is a tool that uses machine learning or statistical techniques to predict the likelihood of defects in a software system, based on various factors such as code complexity, code churn, code coverage, code smells, etc. Bug prediction tools are not used by testers to track the bugs they found, which are the actual defects that have been detected and reported during testing. Bugs are usually tracked by defect management tools, which are tools that help testers to record, monitor, analyze, and resolve defects.
A continuous integration tool is a tool that enables the integration of code changes from multiple developers into a shared repository, and the execution of automated builds and tests, in order to ensure the quality and consistency of the software system. Continuous integration tools are not used by testers to automatically generate test cases from a model, which are test cases that are derived from a representation of the system under test, such as a state diagram, a decision table, a use case, etc. Test cases can be automatically generated by test design tools, which are tools that support the implementation and maintenance of test cases, based on test design specifications or test models.

NEW QUESTION # 100
In addition to thorough testing of the requirements specification, a development team aims to involve users as early as possible in the development process, using practices such as prototyping, to ensure that the software systems being developed will meet the users' expectations. This approach is especially useful at mitigating the risks associated with one of the seven testing principles, which one?

• A. Tests wear out
• B. Absence-of-errors fallacy
• C. Working software over comprehensive documentation
• D. Defects cluster together

Answer: B

Explanation:
The absence-of-errors fallacy is one of the seven testing principles mentioned in the ISTQB syllabus. This principle states that even if no defects are found in the software, it does not guarantee that the software is usable and meets the user needs and expectations. By involving users early in the development process through practices like prototyping, the team can gather feedback to ensure that the software aligns with user expectations, thereby addressing the risk of this fallacy.
