You are running a performance test with the objective of finding possible network bottlenecks in interfaces between components of a system. Which of the following statements describes this test? a) A functional test during the integration test level b) A non-functional test during the integration test level c) A functional test during the component test level d) A non-functional test during the component test level Select ONE option. Explanation / Rationale a) Is not correct. While this test does match the description of an integration test, it is a non-functional test b) Is correct. This test matches the description of an integration test and it is a non-functional test c) Is not correct. This test does not match the description of a component test and it is not a functional test d) Is not correct. While this test is a non-functional test, it does not match the description of a component test 2 / 40 2. You are defining the process for carrying out product risk analysis as part of each iteration on an Agile project. Which of the following is the proper place to document this process in a test plan? a) Scope of testing b) Approach of testing c) Metrics of testing d) Configuration management of the test object Select ONE option. Explanation / Rationale a) Is not correct. While scope is a topic addressed in a test plan, the implementation of a risk-based testing strategy on this project is the approach, so this topic should be addressed in that section b) Is correct. Approach is a topic addressed in a test plan and the implementation of a risk-based testing strategy on this project is the approach c) Is not correct. While metrics for test monitoring and control is a topic addressed in a test plan, the implementation of a risk-based testing strategy on this project is the approach, so this topic should be addressed in that section d) Is not correct. Configuration management is not a topic addressed in a test plan 3 / 40 3. 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 4 / 40 4. 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 5 / 40 5. Which of the following metrics would be MOST useful to monitor during test execution? a) Percentage of executed test cases b) Average number of testers involved in the test execution c) Coverage of requirements by source code d) Percentage of test cases already created and reviewed Select ONE option. Explanation / Rationale a) Is correct. Test case execution (e.g., number of test cases run/not run, and test cases passed/failed) b) Is not correct. This metric can be measured, but its value is low. The number of testers does not give any information about the quality of the test object or test progress c) Is not correct. the coverage of requirements by source code is not measured during test execution. At most, the TEST(!) coverage of the code or requirements is measured d) Is not correct. This metric is part of test preparation and not test execution 6 / 40 6. 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 7 / 40 7. Programmers often write and execute unit tests against code which they have written. During this self-testing activity, which of the following is a tester mindset that programmers should adopt to perform this unit testing effectively? a) Good communication skills b) Code coverage c) Evaluating code defects d) Attention to detail Select ONE option. Explanation / Rationale a) Is not correct. The programmer appears to be performing unit testing on their own code b) Is not correct. Code coverage is useful for unit testing, but it is not a tester mindset c) Is not correct. The programmer’s mindset included contemplating what might be wrong with the code, but that is not a tester’s mindset d) Is correct. This tester mindset, attention to detail, will help programmers find defects during unit testing 8 / 40 8. 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 9 / 40 9. 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 10 / 40 10. Which of the following should NOT be a trigger for maintenance testing? a) Decision to test the maintainability of the software b) Decision to test the system after migration to a new operating platform c) Decision to test if archived data is possible to be retrieved d) Decision to test after “hot fixes” Select ONE option. Explanation / Rationale a) Is correct. This is maintainability testing, not maintenance testing b) Is not correct. This is a trigger for maintenance testing: Operational tests of the new environment as well as of the changed software c) Is not correct. This is the trigger for maintenance testing: testing restore/retrieve procedures after archiving for long retention periods d) Is not correct. This is the trigger for maintenance testing: Reactive modification of a delivered software product to correct emergency defects that have caused actual failures 11 / 40 11. Which one of the statements below describes the most common situation for a failure discovered during testing or in production? a) The product crashed when the user selected an option in a dialog box b) The wrong version of a compiled source code file was included in the build c) The computation algorithm used the wrong input variables d) The developer misinterpreted the requirement for the algorithm Select ONE option. Explanation / Rationale a) Is correct. A crash is clearly noticeable by the user b) Is not correct. This is a defect, not a failure since there is something wrong in the code. It may not result in a visible or noticeable failure, for example if the changes in the source code file are only in comments c) Is not correct. The use of wrong input variables may not result in a visible or noticeable failure, for example if nobody uses this particular algorithm; or if the wrong input variable has a similar value to the correct input variable; or if the FALSE result of the algorithm is not used d) Is not correct. This type of fault will not necessarily lead to a failure; for example, if no one uses this special algorithm 12 / 40 12. 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 units’ field is 0.1 units. Which of the following is a MINIMAL set of input values that cover the equivalence partitions for this field? a) 10.0, 28.0 b) 0.4, 0.5, 25.0, 25.1 c) 0.2, 0.9, 29.5 d) 12.3 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. Only two of the equivalence partitions are covered in this set of tests b) Is not correct. Each of those four boundary values are included in this set of tests, but the question asked for equivalence partition coverage with minimal tests, so either 0.5 or 25.0 should be dropped c) Is correct. Each of these three equivalence partitions are covered in this set of tests d) Is not correct. Only one of those equivalence partitions is covered by this test 13 / 40 13. 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 14 / 40 14. 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 15 / 40 15. 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 16 / 40 16. 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 17 / 40 17. 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 18 / 40 18. 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 19 / 40 19. A batch application has been in production unchanged for over two years. It runs overnight once a month to produce statements that will be e-mailed to customers. For each customer, the application goes through every account and lists every transaction on that account in the last month. It uses a nested-loop structure to process customers (outer loop), each customer’s accounts (middle loop), and each account’s transactions (inner loop). One night, the batch application terminates prematurely, failing to e-mail statements to some customers, when it encounters a customer with one account for which no transactions occurred in the last month. This is a very unusual situation and has not occurred in the years since this application was placed in production. While fixing the defect, a programmer asks you to recommend test techniques that are effective against this kind of defect. Which of the following test techniques would most likely have been able to detect the underlying defect? a) Decision testing b) Statement testing c) Checklist-based testing d) Error guessing Select ONE option. Explanation / Rationale a) Is correct. For a loop construct, statement coverage only requires that all statements within the loop are executed, but decision coverage requires testing of both the conditions where the loop is executed and when it is bypassed b) Is not correct. For a loop construct, statement coverage only requires that all statements within the loop are executed, but decision coverage requires testing of both the conditions where the loop is executed and when it is bypassed c) Is not correct. Checklists are based on experience, defect and failure data, knowledge about what is important for the user, and an understanding of why and how software fails, none of which is likely to have led to the inclusion of such a test condition d) Is not correct. While it is possible that someone might anticipate a developer making the mistaken assumption that there would always be at least one transaction in a month for every account, only decision testing guarantees testing of that condition 20 / 40 20. 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 21 / 40 21. 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 22 / 40 22. 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 23 / 40 23. 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 24 / 40 24. 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 25 / 40 25. 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 26 / 40 26. 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 27 / 40 27. 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 28 / 40 28. 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 29 / 40 29. 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 30 / 40 30. 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 31 / 40 31. 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 32 / 40 32. You are working on a video game development project, using Agile methods. It is based on Greek mythology and history, and players can play key roles in scenarios such as the battles between the Greeks and Trojans. Consider the following user story and its associated acceptance criteria: As a player, I want to be able to acquire the Rod of Midas (a new magic object), so that I can turn objects and other players into gold AC1: The Rod must work on any object or player, no matter what size, which can be touched anywhere by the player holding the Rod AC2: Holding the Rod does not change the player holding it into gold AC3: Any object or player touched by the Rod transforms completely into gold within one millisecond AC4: The Rod appears as shown in Prototype O.W.RoM AC5: The transformation starts at the point of contact with the Rod and moves at a rate of one meter per millisecond You are participating in a checklist-based review session of this user story. This user story and its associated acceptance criteria contain which of the following typical defects identified by static testing in this type of work product? a) Deviation from standards b) Contradiction c) Security vulnerability d) Coverage gaps Select ONE option. Explanation / Rationale a) Is not correct. While deviation from standards is a typical, we are not given any standard with which the user stories should comply b) Is correct. Contradiction is a typical requirements defect. AC3 and AC5 conflict if the Rod is touched to an object that extends more than 1 meter in any direction from the point at which touched, since AC1 does not limit the size of the objects to be touched c) Is not correct. While security vulnerabilities are typical defects, there is nothing here related to security d) Is not correct. While test coverage gaps are typical defects, including missing tests for acceptance criteria, we are not provided with any information about which tests do and do not exist 33 / 40 33. 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 34 / 40 34. A mass market operating system software product is designed to run on any PC hardware with an x86-family processor. You are running a set of tests to look for defects related to support of the various PCs that use such a processor and to build confidence that important PC brands will work. What type of test are you performing? a) Performance test b) Processor test c) Functional test d) Portability test Select ONE option. Explanation / Rationale a) Is not correct. The test described is a non-functional test, it is a portability test, not a performance test b) Is not correct. Processor test is not a defined test type c) Is not correct. The test described is a non-functional test, specifically a portability test d) Is correct. Testing supported devices is a non-functional test, specifically a portability test 35 / 40 35. Which of the following statements comparing component testing and system testing is TRUE? a) Component testing verifies the functionality of software modules, program objects, and classes that are separately testable, whereas system testing verifies interfaces between components and interactions between different parts of the system b) Test cases for component testing are usually derived from component specifications, design specifications, or data models, whereas test cases for system testing are usually derived from requirement specifications or use cases c) Component testing only focuses on functional characteristics, whereas system testing focuses on functional and non-functional characteristics d) Component testing is the responsibility of the testers, whereas system testing typically is the responsibility of the users of the system Select ONE option. Explanation / Rationale a) Is not correct. System testing does not test interfaces between components and interactions between different parts of the system; this is a target of integration tests b) Is correct. Examples of work products that can be used as a test basis for component testing include detailed design, code, data model, component specifications. Examples of work products for system testing include system and software requirement specifications (functional and non-functional) use cases c) Is not correct. Component testing does not ONLY focus on functional characteristics d) Is not correct. Component tests are also executed by developers, whereas system testing typically is the responsibility of (independent) testers 36 / 40 36. 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 37 / 40 37. 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) 38 / 40 38. 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 39 / 40 39. Which of the following CORRECTLY matches the roles and responsibilities in a formal review? a) Manager – Decides on the execution of reviews b) Review Leader - Ensures effective running of review meetings c) Scribe – Fixes defects in the work product under review d) Moderator – Monitors ongoing cost-effectiveness Explanation / Rationale a) Is correct. The management decides about performing the review b) Is not correct. The moderator, not the review leader should ensure the effective running of review meetings c) Is not correct. The author fixes the work product under review d) Is not correct. The manager monitors ongoing cost-effectiveness 40 / 40 40. 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 0% Restart quiz
