Which one of the following is NOT included in a test summary report? a) Defining pass/fail criteria and objectives of testing b) Deviations from the test approach c) Measurements of actual progress against exit criteria d) Evaluation of the quality of the test object Select ONE option. Explanation / Rationale a) Is correct. This information has been defined earlier in the test project b) Is not correct. This information is included in a test report: information on what occurred during a test period c) Is not correct. This information is included in a test report: • Status of testing and product quality with respect to the exit criteria or definition of done • Metrics of defects, test cases, test coverage, activity progress, and resource consumption d) Is not correct. This information is included in a test report: Information and metrics to support recommendations and decisions about future actions, such as an assessment of defects remaining, the economic benefit of continued testing, outstanding risks, and the level of confidence in the tested software 2 / 40 2. 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 3 / 40 3. A video application has the following requirement: The application shall allow playing a video on the following display resolution: 1. 640x480 2. 1280x720 3. 1600x1200 4. 1920x1080 Which of the following list of test cases is a result of applying the equivalence partitioning test technique to test this requirement? a) Verify that the application can play a video on a display of size 1920x1080 (1 test case) b) Verify that the application can play a video on a display of size 640x480 and 1920x1080 (2 test cases) c) Verify that the application can play a video on each of the display sizes in the requirement (4 test cases) d) Verify that the application can play a video on any one of the display sizes in the requirement (1 test case) Select ONE option. Explanation / Rationale a) Is not correct. See reason from correct answer b) Is not correct. See reason from correct answer c) Is correct. This is a case where the requirement gives an enumeration of discrete values. Each enumeration value is an equivalence class by itself; therefore, each will be tested when using equivalence partitioning test technique d) Is not correct. See reason from correct answer 4 / 40 4. 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 5 / 40 5. 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 6 / 40 6. You are testing an unattended gasoline pump that only accepts credit cards. Once the credit card is validated, the pump nozzle placed into the tank, and the desired grade selected, the customer enters the desired amount of fuel in gallons using the keypad. The keypad only allows the entry of digits. Fuel is sold in tenths (0.1) of a gallon, up to 50.0 gallons. Which of the following is a minimum set of desired amounts that covers the equivalence partitions for this input? a) 0.0, 20.0, 60.0 b) 0.0, 0.1, 50.0 c) 0.0, 0.1, 50.0, 70.0 d) -0.1, 0.0, 0.1, 49.9, 50.0, 50.1 Select ONE option. Explanation / Rationale There are three equivalence partitions: • No sale completed (0.0 gallons) • A valid sale occurs (0.1 to 50.0 gallons) • An invalid amount is selected (50.1 or more gallons) Thus: a) Is correct. This set of input values has exactly one test per equivalence partition b) Is not correct. This set of input values has does not cover the invalid amount partition c) Is not correct. This set of input values has two tests for the valid sale equivalence partition, which is not the minimum d) Is not correct. This set of input values covers the three-point boundary values for the two boundaries, not the minimum number required to cover the equivalence partitions 7 / 40 7. Which of the following statements BEST describes how test cases are derived from a use case? a) Test cases are created to exercise defined basic, exceptional and error behaviors performed by the system under test in collaboration with actors b) Test cases are derived by identifying the components included in the use case and creating integration tests that exercise the interactions of these components c) Test cases are generated by analyzing the interactions of the actors with the system to ensure the user interfaces are easy to use d) Test cases are derived to exercise each of the decision points in the business process flows of the use case, to achieve 100% decision coverage of these flows Select ONE option. Explanation / Rationale a) Is correct. This explains that each use case specifies some behavior that a subject can perform in collaboration with one or more actors. It also (later) explains that tests are designed to exercise the defined behaviors (basic, exceptional and errors) b) Is not correct. Use cases normally specify requirements, and so do not ‘include’ the components that will implement them c) Is not correct. Tests based on use cases do exercise interactions between the actor and the system, but they are focused on the functionality and do not consider the ease of use of user interfaces d) Is not correct. Tests do cover the use case paths through the use case, but there is no concept of decision coverage of these paths, and certainly not of business process flows 8 / 40 8. You are working as a tester on an Agile team and have participated in over two dozen user story refinement sessions with the product owner and the developers on the team at the start of each iteration. As the reviews have gotten more effective at detecting defects in user stories and the product owner more proficient at correcting those defects, you and the team notice that the team’s velocity, as shown in your burndown charts, has started to increase. Which of the following is a benefit of static testing that is MOST DIRECTLY related to the team’s increased velocity? a) Increasing total cost of quality b) Reducing testing cost c) Increasing development productivity d) Reducing total cost of quality Select ONE option. Explanation / Rationale a) Is not correct. Reviews reduce, not increase, the total cost of quality b) Is not correct. Increasing velocity is a sign of increasing development productivity overall, not just testing, so B only partially applies c) Is correct. Velocity is a way of measuring productivity in Agile development d) Is not correct. The benefit mentioned here has to do with increasing overall development team productivity 9 / 40 9. Which of the following is an example of a failure in a car cruise control system? a) The developer of the system forgot to rename variables after a cut-and-paste operation b) Unnecessary code that sounds an alarm when reversing was included in the system c) The system stops maintaining a set speed when the radio volume is increased or decreased d) The design specification for the system wrongly states speeds Select ONE option. Explanation / Rationale a) Is not correct. This is an example of a mistake made by the developer b) Is not correct. This is an example of a defect (something wrong in the code that may cause a failure) c) Is correct. This is a deviation from the expected functionality - a cruise control system should not be affected by the radio d) Is not correct. This is an example of a defect (something wrong in a specification that may cause a failure if subsequently implemented) 10 / 40 10. You are engaged in planning a test effort for a new mobile banking application. As part of estimation, you first meet with the proposed testers and others on the project. The team is well-coordinated and has already worked on similar projects. To verify the resulting estimate, you then refer to some industry averages for testing effort and costs on similar projects, published by a reputable consultant. Which statement accurately describes your estimation approach? a) A simultaneous expert-based and metrics-based approach b) Primarily an expert-based approach, augmented with a metrics-based approach c) Primarily a metrics-based approach, augmented with an expert-based approach d) Primarily planning poker, checked by velocity from burndown charts Select ONE option. Explanation / Rationale a) Is not correct. The two methods are used sequentially, not simultaneously b) Is correct. The primary sources of information come from the experienced testers, who are the experts. The consultant’s industry averages augment the original estimate from published metrics c) Is not correct. The expert-based approach is the primary approach, augmented by a metrics-based approach d) Is not correct. We do not know if this project is following Agile methods, and burndown charts do not come from external consultants 11 / 40 11. During a period of intensive project overtime, a system architecture document is sent to various project participants, announcing a previously unplanned technical review to occur in one week. No adjustments are made to the participants’ list of assigned tasks. Based on this information alone, which of the following is a factor for review success that is MISSING? a) Appropriate review type b) Adequate time to prepare c) Sufficient metrics to evaluate the author d) Well-managed review meeting Select ONE option. Explanation / Rationale a) Is not correct. Technical reviews are appropriate for technical documents such as a system architecture b) Is correct. Adequate time for preparation is important, but people are working overtime and no adjustments are made for this new set of tasks c) Is not correct. Gathering metrics from a review to evaluate participants is a factor that leads to failure, not success, because it destroys trust d) Is not correct. A well-managed review meeting is important, but there is no reason to think the review meeting will not be well managed based on the information provided 12 / 40 12. A product owner says that your role as a tester on an Agile team is to catch all the bugs before the end of each iteration. Which of the following is a testing principle that could be used to respond to this (false) statement? a) Defect clustering b) Testing shows the presence of defects c) Absence of error fallacy d) Root cause analysis Select ONE option. Explanation / Rationale a) Is not correct. Defect clustering has to do with where defects are most likely to be found, not whether all of them can be found b) Is correct. Testing can show the presence of defects but cannot prove their absence, which makes it impossible to know if you have caught all the bugs. Further, the impossibility of exhaustive testing makes it impossible for you to catch all the bugs c) Is not correct. This principle says that you can find and remove many bugs but still release an unsuccessful software product, which is not what the product owner is asking you to ensure d) Is not correct. Root cause analysis is not a testing principle 13 / 40 13. Which of the following statements BEST describes how tasks are divided between the test manager and the tester? a) The test manager plans testing activities and chooses the standards to be followed, while the tester chooses the tools and set the tools usage guidelines b) The test manager plans, coordinates, and controls the testing activities, while the tester automates the tests c) The test manager plans, monitors, and controls the testing activities, while the tester designs tests and decides on the release of the test object d) The test manager plans and organizes the testing and specifies the test cases, while the tester executes the tests Select ONE option. Explanation / Rationale a) Is not correct. Selection of tools is a test manager task b) Is correct. See reasons from incorrect answers c) Is not correct. The tester does not decide on the release of the test object d) Is not correct. The tester specifies the test cases, the test manager does the prioritization 14 / 40 14. Which one of the following is MOST likely to be a benefit of test execution tools? a) It is easy to create regression tests b) It is easy to maintain version control of test assets c) It is easy to design tests for security testing d) It is easy to run regression tests Select ONE option. Explanation / Rationale a) Is not correct. The benefits are not when creating regressions tests, more in executing them b) Is not correct. This is done by configuration management tools c) Is not correct. This needs specialized tools d) Is correct. Reduction in repetitive manual work (e.g., running regression tests, environment set up/tear down tasks, re-entering the same test data, and checking against coding standards), thus saving time 15 / 40 15. Which of the following statements BEST compares the purposes of confirmation testing and regression testing? a) The purpose of regression testing is to ensure that all previously run tests still work correctly, while the purpose of confirmation testing is to ensure that any fixes made to one part of the system have not adversely affected other parts b) The purpose of confirmation testing is to check that a previously found defect has been fixed, while the purpose of regression testing is to ensure that no other parts of the system have been adversely affected by the fix c) The purpose of regression testing is to ensure that any changes to one part of the system have not caused another part to fail, while the purpose of confirmation testing is to check that all previously run tests still provide the same results as before d) The purpose of confirmation testing is to confirm that changes to the system were made successfully, while the purpose of regression testing is to run tests that previously failed to ensure that they now work correctly Select ONE option. Explanation / Rationale a) Is not correct. Although the description of regression testing is largely correct, the description of confirmation testing (which should be testing a defect has been fixed) is not correct b) Is correct. The descriptions of both confirmation and regression testing match the intent of those in the syllabus c) Is not correct. Although the description of regression testing is largely correct, the description of confirmation testing (re-running all previously run tests to get the same results) is not correct, as the purpose of confirmation testing is to check that tests that previously failed now pass (the fix worked) d) Is not correct. Although the description of confirmation testing is largely correct, the description of regression testing (re-running tests that previously failed) is not correct (this is a more detailed description of confirmation testing) 16 / 40 16. 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 17 / 40 17. During an Agile development effort, a product owner discovers a previously unknown regulatory requirement that applies to most of the user stories within a particular epic. The user stories are updated to provide for the necessary changes in software behavior. The programmers on the team are modifying the code appropriately. As a tester on the team, what types of tests will you run? a) Confirmation tests b) Regression tests c) Functional tests d) Change-related tests Select ONE option. Explanation / Rationale The change in behavior may be either functional or non-functional you need to run change-related tests, some of which are confirmation tests and others are regression tests. Thus: a) Is not correct b) Is not correct c) Is not correct d) Is correct 18 / 40 18. Which of the following statements correctly describes the difference between testing and debugging? a) Testing identifies the source of defects; debugging analyzes the defects and proposes prevention activities b) Dynamic testing shows failures caused by defects; debugging eliminates the defects, which are the source of failures c) Testing removes faults; but debugging removes defects that cause the faults d) Dynamic testing prevents the causes of failures; debugging removes the failures Select ONE option. Explanation / Rationale a) Is not correct. Testing does not identify the source of defects, debugging identifies the source of defects b) Is correct. Dynamic testing can show failures that are caused by defects in the software. Debugging eliminates the defects, which are the source of failures c) Is not correct. Testing does not remove faults, but debugging removes faults, which is synonyms for defects, that may cause the failures d) Is not correct. Dynamic testing does not directly prevent the causes of failures (defects) but detects the presence of defects 19 / 40 19. 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 20 / 40 20. 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 21 / 40 21. 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” 22 / 40 22. 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 23 / 40 23. Which one of the following answers describes a test condition? a) A distinguishing characteristic of a component or system b) A testable aspect of a component or system identified as a basis for testing c) The degree to which a software product provides functions which meet stated and implied needs when the software is used under specified conditions d) Test cases designed to execute combinations of conditions and actions resulting from them Select ONE option. Explanation / Rationale a) Is not correct. Definition of feature according to glossary b) Is correct. From glossary c) Is not correct. Definition of functionality suitability according to glossary d) Is not correct. Like Definition of Decision table testing according to glossary 24 / 40 24. Consider the following list of undesirable outcomes that could occur on a mobile app development effort: A. Incorrect totals on screens B. Change to acceptance criteria during acceptance testing C. Users find the soft keyboard too hard to use with your app D. System responds too slowly to user input during search string entry E. Testers not allowed to report test results in daily standup meetings Which of the following properly classifies these outcomes as project and product risks? a) Product risks: B, E; Project risks: A, C, D b) Product risks: A, C, D; Project risks: B, E c) Product risks: A, C, D, E Project risks: B d) Product risks: A, C Project risks: B, D, E Select ONE option. Explanation / Rationale Product risks exist when a work product may fail to satisfy legitimate needs, while project risks are situations that could have a negative impact on the project’s ability to achieve its objectives. So: A. Incorrect totals on screens = product risk B. Change to acceptance criteria during acceptance testing = project risk C. Users find the soft keyboard too hard to use with your app = product risk D. System responds too slowly to user input during search string entry = product risk E. Testers not allowed to report test results in daily standup meetings = project risk Thus: a) Is not correct. This list is entirely backwards b) Is correct c) Is not correct. While E is about product quality and product risks, the failure to communicate test results is a project risk per the syllabus d) Is not correct. Product risks can be functional and non-functional, so d is also a product risk 25 / 40 25. Which of the following statements is a valid objective for testing? a) The test should start as late as possible so that development had enough time to create a good product b) To validate whether the test object works as expected by the users and other stakeholders c) To prove that all possible defects are identified d) To prove that any remaining defects will not cause any failures Select ONE option. Explanation / Rationale a) Is not correct. Contradiction to principle 3: “Early testing saves time and money” b) Is correct. This is one objective of testing c) Is not correct. Principle #2 states that exhaustive testing is impossible, so one can never prove that all defects were identified d) Is not correct. To make an assessment whether a defect will cause a failure or not, one must detect the defect first. Saying that no remaining defect will cause a failure implicitly means that all defects were found. This again contradicts principle #2 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. During a project following Agile methods, you find a discrepancy between the developer’s interpretation of an acceptance criteria and the product owner’s interpretation, which you bring up during a user story refinement session. Which of the following is a benefit of test independence exemplified by this situation? a) Recognizing different kinds of failures b) Taking primary responsibility for quality c) Removing a defect early d) Challenging stakeholder assumptions Select ONE option. Explanation / Rationale a) Is not correct. While recognizing different kinds of failures is a benefit of tester independence, in the scenario here no code yet exists that can fail, and the problem is that the developer and product owner are both assuming different things about the acceptance criteria b) Is not correct. Developers losing a sense of responsibility for quality is a drawback, not a benefit c) Is not correct. While the effect of the discovery of this disagreement is the earlier removal of the defect, prior to coding, defects can be discovered early by various people, not just independent testers d) Is correct. Challenging stakeholder assumptions is a benefit of tester independence, and here the developer and product owner are both assuming different things about the acceptance criteria 28 / 40 28. What is checklist-based testing? a) A test technique in which tests are derived based on the tester's knowledge of past faults, or general knowledge of failures b) A test technique based on an analysis of the specification of a component or system c) An experience-based test technique whereby the experienced tester uses a list of items to be noted, checked, or remembered, or a set of rules or criteria against which a product must be verified d) An approach to testing where the testers dynamically design and execute tests based on their knowledge, exploration of the test item and the results of previous tests Select ONE option. Explanation / Rationale a) Is not correct. This is error guessing b) Is not correct. This is black-box test technique c) Is correct. See reasons from incorrect answers d) Is not correct. This is exploratory testing 29 / 40 29. As a test manager you are responsible for testing the following parts of requirements: • R1 - Process anomalies • R2 - Synchronization • R3 - Approval • R4 - Problem solving • R5 - Financial data • R6 - Diagram data • R7 - Changes to the user profile Notation: Logical requirement dependencies (A -> B means, that B depends on A): Which one of the following options structures the test execution schedule according to the requirement dependencies? a) R1 ; R3 ; R4 ; R7 ; R2 ; R5 ; R6 b) R1 ; R3 ; R2 ; R4 ; R7 ; R5 ; R6 c) R1 ; R3 ; R2 ; R5 ; R6 ; R4 ; R7 d) R1 ; R2 ; R5 ; R6 ; R3 ; R4 ; R7 Select ONE option. Explanation / Rationale a) Is not correct. R4 is dependent on R2, so R2 should be tested before R4 b) Is not correct. R4 is dependent on R2, R5 and R6, so R5 and R6 should be tested before R4 c) Is correct. The tests are specified in a sequence that takes the dependencies into account d) Is not correct. R2 is dependent on R3, so R3 should be tested before R2 30 / 40 30. Which of the following is a typical objective of testing? a) To find defects and failures b) To validate the project plan works as required c) Ensuring of complete testing d) Comparing actual results with expected results Select ONE option. Explanation / Rationale a) Is correct. One of the major objectives of testing b) Is not correct. Validation of the project plan would be a project management activity c) Is not correct. Contradiction to principle #2; complete/exhaustive testing is not possible d) Is not correct. “Comparing actual results with expected results” is a test performing activity, but not a test objective 31 / 40 31. Which of the following descriptions of statement coverage is CORRECT? a) Statement coverage is a measure of the number of lines of source code exercised by tests b) Statement coverage is a measure of the proportion of executable statements in the source code exercised by tests c) Statement coverage is a measure of the percentage of lines of source code (without comments) exercised by tests d) Statement coverage is a measure of the number of executable statements in the source code exercised by tests Select ONE option. Explanation / Rationale a) Is not correct. Statement coverage is a measure of the proportion of executable statements exercised by tests. The number of executable statements is often close to the number of lines of code minus the comments, but this option only talks about the number of lines of code exercised and not the proportion exercised b) Is correct. Statement coverage is a measure of the proportion of executable statements exercised by tests (normally presented as a percentage) c) Is not correct. Statement coverage is a measure of the percentage of executable statements exercised by tests, however many of the lines of source code are not executable (e.g., comments) d) Is not correct. Statement coverage is a measure of the proportion of executable statements exercised by tests. This option only talks about the number of executable statements exercised and not the proportion (or percentage) exercised 32 / 40 32. 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 33 / 40 33. Which of the following is an example of a task that can be carried out as part of the test process? a) Analyzing a defect b) Designing test data c) Assigning a version to a test item d) Writing a user story Select ONE option. Explanation / Rationale a) Is not correct. Analyzing a defect is part of debugging, not testing b) Is correct. Creating test data is a test implementation task c) Is not correct. While a tester may need to identify a test item’s version for results reporting purposes, assigning a test item’s version is part of configuration management d) Is not correct. Writing a user story is not a testing activity and should be done by the product owner 34 / 40 34. Which of the following statements about test estimation approaches is CORRECT? a) With the metrics-based approach, the estimate is based on test measures from the project and so this estimate is only available after the testing starts b) With the expert-based approach, a group of expert users identified by the client recommends the necessary testing budget c) With the expert-based approach, the test managers responsible for the different testing activities predict the expected testing effort d) With the metrics-based approach, an average of the testing costs recorded from several past projects is used as the testing budget Select ONE option. Explanation / Rationale a) Is not correct. Estimates may be updated as more information becomes available, but estimates are needed to assist with planning before the testing starts b) Is not correct. In the expert-based approach, the experts need to be experts in testing, not in using the test object c) Is correct. Test Managers, who will be leading testers doing the testing, are considered experts in their respective areas and suitable for estimating the necessary resources needed d) Is not correct. While it is useful to know the testing costs from previous projects, a more sophisticated approach is needed than simply taking an average of past projects (the new project may not be like the previous projects, e.g., it may be far larger or far smaller than previous projects) 35 / 40 35. Which one of the following test tools is mostly suitable for developers rather than testers? a) Requirement management tools b) Configuration management tools c) Static analysis tools d) Performance testing tools Select ONE option. Explanation / Rationale a) Is not correct. Requirement management tools are not particularly suitable for developers b) Is not correct. Configuration management tools are not particularly suitable for developers c) Is correct. Static analysis tools are especially suitable for developers d) Is not correct. Performance testing tools are not better suited for developers than for testers 36 / 40 36. 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 37 / 40 37. Which of the following provides the BEST description of exploratory testing? a) A testing practice in which an in-depth investigation of the background of the test object is used to identify potential weaknesses that are examined by test cases b) An approach to testing whereby the testers dynamically design and execute tests based on their knowledge, exploration of the test item and the results of previous tests c) An approach to test design in which test activities are planned as uninterrupted sessions of test analysis and design, often used in conjunction with checklist-based testing d) Testing based on the tester's experience, knowledge, and intuition Select ONE option. Explanation / Rationale a) Is not correct. Exploratory testing is often carried out when timescales are short, so making in-depth investigations of the background of the test object is unlikely b) Is correct. Glossary definition c) Is not correct. Based on the Glossary definition of session-based testing, but with test execution replaced by test analysis d) Is not correct. Glossary definition of experience-based testing 38 / 40 38. In a formal review, what is the role name for the participant who runs an inspection meeting? a) Facilitator b) Programmer c) Author d) Project manager Select ONE option. Explanation / Rationale a) Is correct. The facilitator or moderator runs the review meetings b) Is not correct. This is not a role name for a formal review participant c) Is not correct. The facilitator or moderator runs the review meetings d) Is not correct. The facilitator or moderator runs the review meetings 39 / 40 39. A daily radiation recorder for plants produces a sunshine score based on a combination of the number of hours a plant is exposed to the sun (below 3 hours, 3 to 6 hours or above 6 hours) and the average intensity of the sunshine (very low, low, medium, high). Given the following test cases: What is the minimum number of additional test cases that are needed to ensure full coverage of ALL VALID INPUT equivalence partitions? a) 1 b) 2 c) 3 d) 4 Select ONE option. Explanation / Rationale The following valid input equivalence partitions can be identified: • Hours 1. Below 3 hours 2. 3 to 6 hours 3. Above 6 hours • Intensity 4. Very low 5. Low 6. Medium 7. High The given test cases cover the following valid input equivalence partitions: Thus, the missing valid input equivalence partitions are: (2), (5) and (7). These can be covered by two test cases, as (2) can be combined with either (5) or (7). Thus: a) Is not correct b) Is correct c) Is not correct d) Is not correct 40 / 40 40. Which one of the following options is categorized as a black-box test technique? a) A technique based on analysis of the architecture b) A technique checking that the test object is working according to the detailed design c) A technique based on the knowledge of past faults, or general knowledge of failures d) A technique based on formal requirements Select ONE option Explanation / Rationale a) Is not correct. This is a white-box test technique b) Is not correct. This is a white-box test technique c) Is not correct. This is an experience-based test technique d) Is correct. Black-box test techniques are based on an analysis of the appropriate test basis (e.g., formal requirements documents, specifications, use cases, user stories) 0% Restart quiz
