Which of the following tasks is MOST LIKELY to be performed by the test manager? a) Write test summary reports based on the information gathered during testing b) Review tests developed by others c) Prepare and acquire test data d) Analyze, review, and assess requirements, specifications, and models for testability Select ONE option. Explanation / Rationale a) Is correct. One of the typical tasks of a test manager b) Is not correct. One of the typical tasks of a tester c) Is not correct. One of the typical tasks of a tester d) Is not correct. One of the typical tasks of a tester 2 / 40 2. What is quality? a) Activities focused on providing confidence that quality requirements will be fulfilled b) The degree to which a component or system satisfies the stated and implied needs of its various stakeholders c) The degree to which a component or system protects information and data so that persons or other components or systems have the degree of access appropriate to their types and levels of authorization d) The total costs incurred on quality activities and issues and often split into prevention costs, appraisal costs, internal failure costs and external failure costs Select ONE option. Explanation / Rationale a) Is not correct. This is the Glossary definition of quality assurance b) Is correct. This is the Glossary definition of quality c) Is not correct. This is the Glossary definition of security d) Is not correct. This is the Glossary definition of cost of quality 3 / 40 3. Which activities are carried out within the planning of a formal review? a) Collection of metrics for the evaluation of the effectiveness of the review b) Answer any questions the participants may have c) Definition and Verification of fulfillment of entry criteria for the review d) Evaluation of the review findings against the exit criteria Select ONE option. Explanation / Rationale a) Is not correct. ‘Collection of metrics’ belongs to the main activity “Fixing and Reporting” b) Is not correct. ‘Answer any question.’ belongs to the main activity “Initiate Review” c) Is correct. The checking of entry criteria takes place in the planning of a formal review d) Is not correct. The evaluation of the review findings against the exit criteria belongs to the main activity “Issue communication and analysis” 4 / 40 4. Which of the following are two factors that can be used to determine the level of risk? a) Testing and development b) Dynamic and reactive c) Statement and decision d) Likelihood and impact Select ONE option. Explanation / Rationale The level of risk will be determined by the likelihood of an adverse event happening and the impact (the harm) from that event. Thus: a) Is not correct b) Is not correct c) Is not correct d) Is correct 5 / 40 5. Mr. Test has been testing software applications on mobile devices for a period of 5 years. He has a wealth of experience in testing mobile applications and achieves better results in a shorter time than others. Over several months, Mr. Test did not modify the existing automated test cases and did not create any new test cases. This leads to fewer and fewer defects being found by executing the tests. What principle of testing did Mr. Test not observe? a) Testing depends on the environment b) Exhaustive testing is not possible c) Repeating of same tests will not find new defects d) Defects cluster together Select ONE option. Explanation / Rationale a) Is not correct. Testing is context dependent, regardless of it being manual or automated (principle #6), but does not result in detecting a decreasing number of faults as described above b) Is not correct. Exhaustive testing is impossible, regardless of the amount of effort put into testing (principle #2) c) Is correct. Principle #5 says “If the same tests are repeated over and over again, eventually these tests no longer find any new defects. To detect new defects, existing tests and test data may need changing, and new tests may need to be written.” Automated regression testing of the same test cases will not bring new findings d) Is not correct. ”Defect cluster together” (principle #4). A small number of modules usually contain most of the defects, but this does not mean that fewer and fewer defects will be found 6 / 40 6. Which of the following tools is most useful for reporting test metrics? a) Test management tool b) Static analysis tool c) Coverage tool d) Model-Based testing tools Select ONE option. Explanation / Rationale a) Is correct. Test management tools support the activities associated with test manager including metrics b) Is not correct. Static code analysis metrics would have to do with the code only, not testing as a whole c) Is not correct. These tools report on test basis coverage and code coverage only, not testing as a whole d) Is not correct. Model-Based testing tools focus on one specific area, not testing as a whole 7 / 40 7. How can white-box testing be applied during user acceptance testing? a) To check if large volumes of data can be transferred between integrated systems b) To check if all code statements and code decision paths have been executed c) To check if all work process flows have been covered d) To cover all web page navigations Select ONE option. Explanation / Rationale a) Is not correct. Relevant for integration testing b) Is not correct. Relevant for component testing c) Is correct. For acceptance testing, tests are designed to cover all workflows defined in the functional requirements documents. d) Is not correct. Relevant for system testing 8 / 40 8. In what way can testing be part of Quality Assurance? a) It ensures that requirements are detailed enough b) Testing reduces the risk of poor software quality c) It ensures that standards in the organization are followed d) It measures the quality of software in terms of number of executed test cases Select ONE option. Explanation / Rationale a) Is not correct. Static testing (reviews) contributes, but could not ensure, that requirements are detailed enough b) Is correct. Testing contributes to the achievement of quality in a variety of ways, e.g., such as reducing the risk of inadequate software quality c) Is not correct. This is quality assurance but not testing d) Is not correct. The quality cannot be measured by counting the number of executed test cases without knowing the outcome 9 / 40 9. Given the following test activities and tasks: A. Test design B. Test implementation C. Test execution D. Test completion 1. Entering change requests for open defect reports 2. Identifying test data to support the test cases 3. Prioritizing test procedures and creating test data 4. Analyzing discrepancies to determine their cause Which of the following BEST matches the activities with the tasks? a) A-2, B-3, C-4, D-1 b) A-2, B-1, C-3, D-4 c) A-3, B-2, C-4, D-1 d) A-3, B-2, C-1, D-4 Select ONE option. Explanation / Rationale The correct pairing of test activities and tasks is: A. Test design – (2) Identifying test data to support the test cases B. Test implementation – (3) Prioritizing test procedures and creating test data C. Test execution – (4) Analyzing discrepancies to determine their cause D. Test completion – (1) Entering change requests for open defect reports Thus: a) Is correct b) Is not correct c) Is not correct d) Is not correct 10 / 40 10. Which of the following is MOST likely to be an example of a PRODUCT risk? a) The expected security features may not be supported by the system architecture b) The developers may not have time to fix all the defects found by the test team c) The test cases may not provide full coverage of the specified requirements d) The performance test environment may not be ready before the system is due for delivery Select ONE option. Explanation / Rationale a) Is correct. If the expected security features are not supported by the system architecture, then the system could be seriously flawed. As the system being produced is the problem here, it is a product risk b) Is not correct. If the developers run over budget, or run out of time, that is a problem with the running of the project – it is a project risk c) Is not correct. If the test cases do not provide full coverage of the requirements, this means the testing may not fulfil the requirements of the test plan – it is a project risk d) Is not correct. If the test environment is not ready, this means the testing may not be done, or it may have to be done on a different environment and it is impacting how the project is run – it is a project risk 11 / 40 11. You are testing an e-commerce system that sells cooking supplies such as spices, flour, and other items in bulk. The units in which the items are sold are either grams (for spices and other expensive items) or kilograms (for flour and other inexpensive items). Regardless of the units, the smallest valid order amount is 0.5 units (e.g., half a gram of cardamom pods) and the largest valid order amount is 25.0 units (e.g., 25 kilograms of sugar). The precision of the unit’s field is 0.1 units. Which of the following is a set of input values that cover the boundary values with two-point boundary values for this field? a) 0.3, 10.0, 28.0 b) 0.4, 0.5, 0.6, 24, 9, 25, 0, 25.1 c) 0.4, 0.5, 25.0 25.1 d) 0.5, 0.6, 24.9, 25.0 Select ONE option. Explanation / Rationale There are three equivalence partitions, with the boundaries as shown: • Invalid too low (0.4 and below) • Valid (0.5 to 25.0) • Invalid too high (25.1 and above) Thus: a) Is not correct. None of those four boundary values are included in this set of tests. These tests do cover the equivalence partitions b) Is not correct. All these four boundary values are included in this set of tests, but two additional values are included, one for each boundary. These are the values associated with three-point boundary value analysis c) Is correct. Each of those four two-point boundary values are included in this set of tests d) Is not correct. These four values are all included in the valid partition 12 / 40 12. Consider the following types of defects that a test level might focus on: a) Defects in separately testable modules or objects b) Not focused on identifying defects c) Defects in interfaces and interactions d) Defects in the whole test object Which of the following list correctly matches test levels from the Foundation syllabus with the defect focus options given above? a) 1 = performance test; 2 = component test; 3 = system test; 4 = acceptance test b) 1 = component test; 2 = acceptance test; 3 = system test; 4 = integration test c) 1 = component test; 2 = acceptance test; 3 = integration test; 4 = system test d) 1 = integration test; 2 = system test; 3 = component test; 4 = acceptance test Select ONE option. Explanation / Rationale Performance testing is a test type, not a test level. Component testing focuses on defects in separately testable modules or objects, integration testing on defects in interfaces and interactions, system testing on defects in the whole test object, and acceptance testing is not typically focused on identifying defects. Thus: a) Is not correct b) Is not correct c) Is correct d) Is not correct 13 / 40 13. A phone ringing momentarily distracts a programmer, causing the programmer to improperly program the logic that checks the upper boundary of an input variable. Later, during system testing, a tester notices that this input field accepts invalid input values. The improperly coded logic for the upper boundary check is: a) The root-cause b) The failure c) The error d) The defect Select ONE option. Explanation / Rationale a) Is not correct. The root cause is the distraction that the programmer experienced while programming b) Is not correct. The accepting of invalid inputs is the failure c) Is not correct. The error is the mistaken thinking that resulted in putting the defect in the code d) Is correct. The problem in the code is a defect 14 / 40 14. Which of the following lists contains only typical exit criteria from testing? a) Reliability measures, test coverage, schedule and status about fixing defect and remaining risks b) Reliability measures, test coverage, degree of tester’s independence and product completeness c) Reliability measures, test coverage, test cost, availability of test environment, time to market and product completeness d) Time to market, remaining defects, tester qualification, availability of testable use cases, test coverage and test cost Select ONE option. Explanation / Rationale a) Is correct. See reasons from incorrect answers b) Is not correct. The “degree of tester’s independence” does not play a role in exit criteria c) Is not correct. “Availability of test environment” is an entry criterion d) Is not correct. “The Qualification of Tester” is not a typical exit criterion 15 / 40 15. An employee’s bonus is to be calculated. It cannot be negative, but it can be calculated down to zero. The bonus is based on the length of employment: • Less than or equal to 2 years • More than 2 years but less than 5 years • 5 to 10 years inclusively • Longer than 10 years What is the minimum number of test cases required to cover all valid equivalence partitions for calculating the bonus? a) 3 b) 5 c) 2 d) 4 Select ONE option. Explanation / Rationale a) Is not correct. One too few (see the four correct partitions in the correct answer) b) Is not correct. One too much (see the four correct partitions in the correct answer) c) Is not correct. Two too few (see the four correct partitions in the correct answer) d) Is correct. The 4 equivalence partitions correspond to the description in the question, i.e., at least one test case must be created for each equivalence partition: 1. Equivalence partition: 0 ≤ employment time ≤ 2 2. Equivalence partition: 2 < employment time < 5 3. Equivalence partition: 5 ≤ employment time ≤ 10 4. Equivalence partition: 10 < employment time 16 / 40 16. You have just completed a pilot project for a regression testing tool. You understand the tool much better and have tailored your testing process to it. You have standardized an approach to using the tool and its associated work products. Which of the following is a typical test automation pilot project goal that remains to be carried out? a) Learn more details about the tool b) See how the tool would fit with existing processes and practices c) Decide on standard ways of using, managing, storing, and maintaining the tool and the test assets d) Assess whether the benefits will be achieved at reasonable cost Select ONE option. Explanation / Rationale a) Is not correct. This is an objective for a pilot, but you have achieved it because you understand the tool much better due to the pilot b) Is not correct. This is an objective for a pilot, but you have achieved it because you have tailoring your testing processes c) Is not correct. This is an objective for a pilot, but you have achieved it because you have standardized an approach to using the tool and its associated work products d) Is correct. Assessing the benefits and configuring the metrics collection are the two objectives missing from this list 17 / 40 17. Consider the following state transition diagram for a credit-card only, unattended gasoline pump: Assume that you want to develop the minimum number of tests to cover each transition in the state transition diagram. Assume further that each test must start at the beginning state, waiting for customer, and each test ends when a transition arrives at the beginning state. How many tests do you need? a) 4 b) 7 c) 1 d) Infinite Select ONE option. Explanation / Rationale Each transition must be traversed at least once. To do so, the first test can cover the happy path, a successful purchase, the next test cancels, or timeout from waiting for pumping, the next test cancels, or timeout from waiting for fuel type, and the last test the insertion of an invalid credit card. While the order is immaterial, fewer than four tests fail to cover one of the transitions inbound to waiting for customer or violates the rules about where a test starts or ends. More than four tests include tests that re-traverse already-covered transitions. Thus: a) Is correct b) Is not correct c) Is not correct d) Is not correct 18 / 40 18. Which of the following is a defect rather than a root cause in a fitness tracker? a) Because the author of the requirements was unfamiliar with the domain of fitness training, he therefore wrongly assumed that users wanted heartbeat in beats per hour b) The tester of the smartphone interface had not been trained in state transition testing, so missed a major defect c) An incorrect configuration variable implemented for the GPS function could cause location problems during daylight saving times d) Because the designer had never worked on wearable devices before, she as designer of the user interface therefore misunderstood the effects of reflected sunlight Select ONE option. Explanation / Rationale a) Is not correct. The lack of familiarity of the requirements author with the fitness domain is a root cause b) Is not correct. The lack of training of the tester in state transition testing was one of the root causes of the defect (the developer presumably created the defect, as well) c) Is correct. The incorrect configuration data represents faulty software in the fitness tracker (a defect), that may cause failures d) Is not correct. The lack of experience in designing user interfaces for wearable devices is a typical example of a root cause of a defect 19 / 40 19. 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. Are the entry criteria clearly defined for each activity? iii. Are 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 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. Explanation / Rationale a) Is not correct. It is described that the software architect must have completed the system specification b) Is not correct. ‘Checklist-based’, last sentence it is documented that you should also look for defects outside the checklist c) Is not correct. It is described: every reviewer did his review done comment d) Is correct. It is described that a checklist is available, but who provides the checklist? 20 / 40 20. Which of the following statements about test types and test levels is CORRECT? a) Functional and non-functional testing can be performed at system and acceptance test levels, while white-box testing is restricted to component and integration testing b) Functional testing can be performed at any test level, while white-box testing is restricted to component testing c) It is possible to perform functional, non-functional and white-box testing at any test level d) Functional and non-functional testing can be performed at any test level, while white-box testing is restricted to component and integration testing Select ONE option. Explanation / Rationale a) Is not correct. It is possible to perform any of the test types (functional, non-functional, white-box) at any test level - so, although it is correct that functional and non-functional testing can be performed at system and acceptance test levels, it is incorrect to state that white-box testing is restricted to component and integration testing b) Is not correct. It is possible to perform any of the test types (functional, non-functional, white-box) at any test level - so, it is incorrect to state that white-box testing is restricted to component testing c) Is correct. It is possible to perform any of the test types (functional, non-functional, white-box) at any test level d) Is not correct. It is possible to perform any of the test types (functional, non-functional, white-box) at any test level - so, it is incorrect to state that white-box testing is restricted to component testing and integration testing 21 / 40 21. Which of the review types below is the BEST option to choose when the review must follow a formal process based on rules and checklists? a) Informal Review b) Technical Review c) Inspection d) Walkthrough Select ONE option. Explanation / Rationale a) Is not correct. Informal review does not use a formal process b) Is not correct. Use of checklists are optional c) Is correct. Inspection is a formal process based on rules and checklists d) Is not correct. Does not explicitly require a formal process and the use of checklists is optional 22 / 40 22. A company's employees are paid bonuses if they work more than a year in the company and achieve a target which is individually agreed before. These facts can be shown in a decision table: Which of the following test cases represents a situation that can happen in real life, and is missing in the above decision table? a) Condition1 = YES, Condition2 = NO, Condition3 = YES, Action= NO b) Condition1 = YES, Condition2 = YES, Condition3 = NO, Action= YES c) Condition1 = NO, Condition2 = NO, Condition3 = YES, Action= NO d) Condition1 = NO, Condition2 = YES, Condition3 = NO, Action= NO Select ONE option. Explanation / Rationale a) Is not correct. If there was no agreement on targets, it is impossible to reach the targets. Since this situation can´t occur, this is not a scenario happening in reality b) Is not correct. The test case is objectively wrong, since under these conditions no bonus is paid because the agreed target was not reached c) Is not correct. There was no agreement on targets, it is impossible to reach the targets. Since this situation can´t occur, this is not a scenario happening in reality d) Is correct. The test case describes the situation that the too short period of employment and the non-fulfilment of the agreed target leads to non-payment of the bonus. This situation can occur in practice but is missing in the decision table 23 / 40 23. A tester participated in a discussion about proposed database structure. The tester identified a potential performance problem related to certain common user searches. This possible problem was explained to the development team. Which of the following is a testing contribution to success that BEST matches this situation? a) Enabling required tests to be identified at an early stage b) Ensuring processes are carried out properly c) Reducing the risk of fundamental design defects d) Reducing the risk of untestable functionality Select ONE option. Explanation / Rationale a) Is not correct. While enabling required tests to be identified in an early stage is a testing contribution to success, there is no indication in the question that the tester did so b) Is not correct. Ensuring processes are carried out properly is part of quality assurance, not a testing contribution to success c) Is correct. Reducing the risk of fundamental design defects is a testing contribution to success. Database structure is related to design, and performance problems can be a significant product risk d) Is not correct. While reducing the risk of untestable functionality is a testing contribution to success, the tester here has not identified something untestable, but rather something that would result in performance tests failing 24 / 40 24. Which of the following BEST describes the concept behind error guessing? a) Error guessing requires you to imagine you are the user of the test object and guess mistakes the user could make interacting with it b) Error guessing involves using your personal experience of development and the mistakes you made as a developer c) Error guessing involves using your knowledge and experience of defects found in the past and typical mistakes made by developers d) Error guessing requires you to rapidly duplicate the development task to identify the sort of mistakes a developer might make Select ONE option. Explanation / Rationale a) Is not correct. error guessing is not a usability technique for guessing how users may fail to interact with the test object b) Is not correct. Although a tester who used to be a developer may use their personal experience to help them when performing error guessing, the technique is not based on prior knowledge of development c) Is correct. The basic concept behind error guessing is that the tester tries to guess what mistakes may have been made by the developer and what defects may be in the test object based on past-experience (and sometimes checklists) d) Is not correct. Duplicating the development task has several flaws that make it impractical, such as the requirement for the tester to have equivalent skills to the developer and the time involved in performing the development. It is not error guessing 25 / 40 25. Which of the following is a true statement about exploratory testing? a) More experienced testers who have tested similar applications and technologies are likely to do better than less experienced testers at exploratory testing b) Exploratory testing does not identify any additional tests beyond those that would result from formal test techniques c) The time required to complete an exploratory testing session cannot be predicted in advance d) Exploratory testing can involve the use of black-box techniques but not white-box techniques Select ONE option. Explanation / Rationale a) Is correct. Exploratory testing is a form of experience-based testing, which benefits from the skills and experience of the tester b) b) Is not correct. Exploratory testing is useful to complement formal testing techniques c) Is not correct. In session-based test management, exploratory testing is conducted within a defined time-box, and the tester uses a test charter containing test objectives to guide the testing d) Is not correct. Exploratory testing can incorporate the use of other black-box, white-box, and experience-based techniques referenced in this syllabus 26 / 40 26. Given that the testing being performed has the following attributes: • Based on interface specifications • Focused on finding failures in communication • The test approach uses both functional and structural test types Which of the following test levels is MOST likely being performed? a) Integration testing b) Acceptance testing c) System testing d) Component testing Select ONE option. Explanation / Rationale Considering the scenario: 1. ‘testing is based on interface specifications’ – the test basis for integration testing includes interface specifications (along with communication protocol specification), while these are not included for any of the other test levels 2. ‘testing is focused on finding failures in communication’ - failures in the communication between tested components is included as a typical failure for integration testing, but failures in communication is not included for any of the other test levels 3. ‘the test approach uses both functional and structural test types’ - functional and structural test types are both included as possible approaches for integration testing, and would also be appropriate for any of the other test levels, although they are only otherwise explicitly mentioned in the syllabus for system testing Thus: a) Is correct b) Is not correct c) Is not correct d) Is not correct 27 / 40 27. Which of the following qualities is MORE likely to be found in a tester’s mindset rather than in a developer’s? a) A tester´s mindset tends to grow and mature as the tester gains experience b) Ability to see what might go wrong c) Good communication with team members d) Focus on getting all things done Select ONE option. Explanation / Rationale a) Is not correct. Both developers and testers gain from experience b) Is correct. Developers are often more interested in designing and building solutions than in contemplating what might be wrong with those solutions c) Is not correct. Both developers and testers should be able to communicate well d) Is not correct. Testers shall focus on the quality, not on the quantity 28 / 40 28. Which one of the following is TRUE? a) The purpose of regression testing is to check if the correction has been successfully implemented, while the purpose of confirmation testing is to confirm that the correction has no side effects b) The purpose of regression testing is to detect unintended side effects, while the purpose of confirmation testing is to check if the system is still working in a new environment c) The purpose of regression testing is to detect unintended side effects, while the purpose of confirmation testing is to check if the original defect has been fixed d) The purpose of regression testing is to check if the new functionality is working, while the purpose of confirmation testing is to check if the original defect has been fixed Select ONE option. Explanation / Rationale a) Is not correct. Regression testing does not check successful implementation of corrections and confirmation testing does not check for side effects b) Is not correct. The statement about confirmation testing should be about regression testing c) Is correct. See reasons from incorrect answers d) Is not correct. Testing new functionality is not regression testing 29 / 40 29. 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.” Which of the following statement is correct? 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 d) The statement is false. The statement is too broad. It may be correct or not, depending on the tested software Select ONE option. Explanation / Rationale a) Is not correct. While the given statement is true, the explanation is not. The relationship between statement and decision coverage is misrepresented b) Is correct. Since any test case will cause the outcome of the “if” statement to be either TRUE or FALSE, by definition we achieved 50% decision coverage c) Is not correct. A single test case can give more than 25% decision coverage, this means according to the statement above always 50 % decision coverage d) Is not correct. The statement is specific and always true, because each test case achieves 50 % decision coverage 30 / 40 30. Which of the following statements about static testing are MOST true? a) Static testing is a cheap way to detect and remove defects b) Static testing makes dynamic testing less challenging c) Static testing makes it possible to find run-time problems early in the lifecycle d) When testing safety-critical system, static testing has less value because dynamic testing finds the defects better Select ONE options. Explanation / Rationale a) Is correct. Defects found early are often much cheaper to remove than defects detected later in the lifecycle b) Is not correct. Dynamic testing still has its challenging because they find other types of defects c) Is not correct. This is dynamic testing d) Is not correct. Static testing is important for safety-critical computer systems 31 / 40 31. Match the following test work products (1-4) with the right description (A-D). 1. Test suite 2. Test case 3. Test script 4. Test charter A. A set of test scripts to be executed in a specific test run B. A set of instructions for the execution of a test C. Contains expected results D. Documentation of test activities in session-based exploratory testing a) 1A, 2C, 3B, 4D b) 1D, 2B, 3A, 4C c) 1A, 2C, 3D, 4B d) 1D, 2C, 3B, 4A Select ONE option. Explanation / Rationale Glossary defines the following tests as: • Test suite: “A set of test scripts or test procedures to be executed in a specific test run.” (1A) • Test case: “A set of preconditions, inputs, actions (where applicable), expected results and post conditions, developed based on test conditions” (2C) • Test script: “A sequence of instructions for the execution of a test” (3B) • Test charter: “Documentation of test activities in session-based exploratory testing” (4D) Thus: a) Is correct b) Is not correct c) Is not correct d) Is not correct 32 / 40 32. Which of the following is MOST likely to be used as a reason for using a pilot project to introduce a tool into an organization? a) The need to evaluate how the tool fits with existing processes and practices and determining what would need to change b) The need to evaluate the test automation skills and training, mentoring and coaching needs of the testers who will use the tool c) The need to evaluate whether the tool provides the required functionality and does not duplicate existing test tools d) The need to evaluate the tool vendor in terms of the training and other support they provide Select ONE option. Explanation / Rationale a) Is correct b) Is not correct. The evaluation of the test automation skills and training, mentoring and coaching needs of the testers who will use the tool should have been performed as part of the tool selection activity c) Is not correct. The decision on whether the tool provides the required functionality and does not duplicate existing tools should have been performed as part of the tool selection activity d) Is not correct. The evaluation of the tool vendor in terms of the training and other support they provide should have been performed as part of the tool selection activity 33 / 40 33. Which of the following statements CORRECTLY describes a role of impact analysis in Maintenance Testing? a) Impact analysis is used when deciding if a fix to a maintained system is worthwhile b) Impact analysis is used to identify how data should be migrated into the maintained system c) Impact analysis is used to decide which hot fixes are of most value to the user d) Impact analysis is used to determine the effectiveness of new maintenance test cases Select ONE option. Explanation / Rationale a) Is correct. Impact analysis may be used to identify those areas of the system that will be affected by the fix, and so the extent of the impact (e.g., necessary regression testing) can be used when deciding if the change is worthwhile b) Is not correct. Although testing migrated data is part of maintenance testing (see conversion testing), impact analysis does not identify how this is done c) Is not correct. Impact analysis shows which parts of a system are affected by a change, so it can show the difference between different hot fixes in terms of the impact on the system, however it does not give any indication of the value of the changes to the user d) Is not correct. Impact analysis shows which parts of a system are affected by a change; it cannot provide an indication of the effectiveness of test cases 34 / 40 34. Which of the following is a common test metric often used to monitor BOTH test preparation and test execution? a) Test case status b) Defect find/fix rates c) Test environment preparation d) Estimated cost to find the next defect Select ONE option. Explanation / Rationale a) Is correct. Percentage of test cases prepared is a common metric during test preparation while percentage of test cases passed, failed, not run, etc., are common during test execution b) Is not correct. Defect reports are typically filed during test execution, based on failures found c) Is not correct. Test environment preparation is part implementation and would generally be complete before test execution d) Is not correct. Defects are typically reported during test execution, based on failures found, so the cost to find the next defect is available during test execution only 35 / 40 35. For which of the following situations is exploratory testing suitable? a) When time pressure requires speeding up the execution of tests already specified b) When the system is developed incrementally, and no test charter is available c) When testers are available who have enough knowledge of similar applications and technologies d) When an advanced knowledge of the system already exists, and evidence is to be if it should be tested intensively Select ONE option. Explanation / Rationale a) Is not correct. Exploratory testing is not suitable to speed up tests, which are already specified. It is most useful when there are few or inappropriate specified requirements or significant time pressure on testing b) Is not correct. The absence of a test charter, which may have been derived from the test analysis, is a poor precondition for the use of exploratory testing c) Is correct. Exploratory tests should be performed by experienced testers with knowledge of similar applications and technologies d) Is not correct. Explorative testing alone is not suitable to provide evidence that the test was very intensive, instead the evidence is provided in combination with other test methods 36 / 40 36. Which of the following BEST matches the descriptions with the different categories of test techniques? 1. Coverage is measured based on a selected structure of the test object 2. The processing within the test object is checked 3. Tests are based on defects’ likelihood and their distribution 4. Deviations from the requirements are checked 5. User stories are used as the test basis Using notation for the following 4 options: Black - Black-box test techniques White - White-box test techniques Experience - Experience-based test techniques a) Black – 4, 5 White – 1, 2; Experience – 3 b) Black – 3 White – 1, 2; Experience – 4, 5 c) Black – 4 White – 1, 2; Experience – 3, 5 d) Black – 1, 3, 5 White – 2; Experience – 4 Select ONE option. Explanation / Rationale The correct pairing of descriptions with the different categories of test techniques is: • Black-box test techniques Deviations from the requirements are checked (4) User stories are used as the test basis (5) • White-box test techniques Coverage is measured based on a selected structure of the test object (1) The processing within the test object is checked (2) • Experience-based test techniques Tests are based on defects’ likelihood and their distribution (3) Thus: a) Is correct b) Is not correct c) Is not correct d) Is not correct 37 / 40 37. Decision table testing is being performed on a speeding fine system. Two test cases have already been generated for rules R1 and R4, which are shown below: Given the following additional test cases: Which two of the additional test cases would achieve full coverage of the complete decision table (when combined with the test cases that have already been generated for rules R1 and R4)? a) DT1, DT2 b) DT2, DT3 c) DT2, DT4 d) DT3, DT4 Select ONE option. Explanation / Rationale The complete decision table is shown below: To achieve full coverage, test cases covering rules 2 and 3 are needed. DT4 satisfies the constraints of rule 2, while DT2 satisfies the constraints of rule 3. Thus: a) Is not correct b) Is not correct c) Is correct d) Is not correct 38 / 40 38. Which of the following options are roles in a formal review? a) Developer, Moderator, Review leader, Reviewer, Tester b) Author, Moderator, Manager, Reviewer, Developer c) Author, Manager, Review leader, Reviewer, Designer d) Author, Moderator, Review leader, Reviewer, Scribe Select ONE option. Explanation / Rationale a) Is not correct. Tester and developer are NOT roles in a formal review b) Is not correct. Developer is NOT a role in a formal review c) Is not correct. Designer is NOT a role in a formal review d) Is correct. See reasons from incorrect answers 39 / 40 39. Which of the following can affect and be part of the (initial) test planning? a) Budget limitations b) Test log c) Failure rate d) Use cases Select ONE options. Explanation / Rationale a) Is correct. Making decisions about what to test are documented in the test plan. This means when you are planning the test and there are budget limitations, prioritizing is needed; what should be tested and what should be omitted b) Is not correct. Test monitoring and control c) Is not correct. Common test metrics d) Is not correct. It is a part of test analysis 40 / 40 40. Consider the following decision table for the portion of an online airline reservation system that allows frequent flyers to redeem points for reward travel: Suppose that there are two equivalence partitions for the condition where “Account/password okay” is not true, one where the account is invalid and another where the account is valid, but the password is invalid. Suppose that there is only one equivalence partition corresponding to the condition where “Account/password okay” is true, where both the account and password are valid. If you want to design tests to cover the equivalence partitions for “Account/password okay” and also for this portion of the decision table, what is the minimum number of tests required? a) 2 b) 3 c) 4 d) 9 Select ONE option. Explanation / Rationale There is at least one test for each column in the decision table. However, column one requires two tests, one where the account is invalid and another where the account is valid, but the password is invalid, so the minimum number of tests is four. Thus: a) Is not correct b) Is not correct c) Is correct d) Is not correct 0% Restart quiz
