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

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)

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

Explanation / Rationale

The following valid equivalence partitions can be identified:

1. Up to 1000 - Couch Potato!
2. Above 1000, up to 2000 - Lazy Bones!
3. Above 2000, up to 4000 - Getting There!
4. Above 4000, up to 6000 - Not Bad!
5. Above 6000 - Way to Go!

The sets of test inputs therefore cover the following partitions:
a) Is not correct. 0 (1), 1000 (1), 2000 (2), 3000 (3), 4000 (3) – 3 partitions (out of 5)
b) Is not correct. 1000 (1), 2001 (3), 4000 (3), 4001 (4), 6000 (4) – 3 partitions (out of 5)
c) Is not correct. 123 (1), 2345 (3), 3456 (3), 4567 (4), 5678 (4) – 3 partitions (out of 5)
d) Is correct. 666 (1), 999 (1), 2222 (3), 5555 (4), 6666 (5) – 4 partitions (out of 5)

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

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

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

Explanation / Rationale

a) Is not correct. Quality should be the responsibility of everyone working on the project and not the sole responsibility of the test team
b) Is not correct. First, it is not a benefit if an external test team does not meet delivery deadlines, and second, there is no reason to believe that external test teams will feel they do not have to meet strict delivery deadlines
c) Is not correct. It is bad practice for the test team to work in complete isolation, and we would expect an external test team to be concerned with changing project requirements and communicate well with developers
d) Is correct. Specifications are never perfect, meaning that assumptions will have to be made by the developer. An independent tester is useful in that they can challenge and verify the assumptions and subsequent interpretation made by the developer

Explanation / Rationale

Considering each statement:

1. Each development activity should have a corresponding testing activity. TRUE
2. Reviewing should start as soon as final versions of documents become available. FALSE – it should start as soon as drafts are available
3. The design and implementation of tests should start during the corresponding development activity. FALSE – the analysis and design of tests should start during the corresponding development activity, not the implementation
4. Testing activities should start in the early stages of the software development lifecycle. TRUE

Thus:
a) Is not correct
b) Is not correct
c) Is not correct
d) Is correct

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

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

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

Explanation / Rationale

a) Is not correct. This is the Glossary definition of condition coverage
b) Is not correct. Decision coverage is a higher level of coverage and the two terms are not defined as synonyms in the Glossary
c) Is not correct. This is the Glossary definition of statement coverage
d) Is correct. This is the Glossary definition of coverage as applied to decisions

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

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

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

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

Explanation / Rationale

a) Is correct. The metrics-based approach: estimating the testing effort based on metrics of former similar projects or based on typical values
b) Is not correct. This is expert-based approach: estimating the tasks based on estimates made by the owners of the tasks or by experts
c) Is not correct. This is expert-based approach: estimating the tasks based on estimates made by the responsible team of the tasks or by experts
d) Is not correct. This is expert-based approach: estimating the tasks based on estimates made by the owners of the tasks or by experts

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

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

Explanation / Rationale

This question is looking for bad application of product risk analysis.

a) Is not correct. As we are told security flaws have a particularly high impact, their risk level will be higher, and thus we have prioritized the security testing ahead of some other testing. Thus, product risk analysis has influenced the testing properly.
b) Is correct. As less defects than expected have been found in the network module, the perceived risk in this area should be lower, and so less testing should be focused on this area, NOT additional testing. Thus, product risk analysis has NOT CORRECTLY influenced the testing in this situation
c) Is not correct. Because the users had problems with the user interface of the previous system, there is now high awareness of the risk associated with the user interface, which has resulted in additional usability testing being planned. Thus, product risk analysis has properly influenced the thoroughness and scope of testing
d) Is not correct. As the time needed to load web pages has been identified as crucial to the success of the new website, the performance of the website should be considered a risk, and the employment of an expert in performance testing helps to mitigate this risk. Thus, product risk analysis has properly influenced the testing

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

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

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

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

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

Explanation / Rationale

Considering each of the pieces of information:

1. Degree of impact (severity) of the defect – the developers are already aware of the problem and are waiting to fix it, so this is a less important piece of information.
2. Identification of the test object – as the developers are already aware of the problem and you are performing system testing, and you have already provided the version of the system you are testing you can assume they know the object that was being tested, so this is a less important piece of information.
3. Details of the test environment – the set-up of the test environment may have a noticeable effect on the test results, and detailed information should be provided, so this is an important piece of information.
4. Urgency/priority to fix – the developers are already aware of the problem and are waiting to fix it, so this is a less important piece of information.
5. Actual results – the actual results may well help the developers to determine what is going wrong with the system, so this is an important piece of information.
6. Reference to test case specification – this will show the developers the tests you ran, including the test inputs that caused the system to fail (and expected results), so this is an important piece of information.

Thus:
a) Is not correct
b) Is not correct
c) Is not correct
d) Is correct

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

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

Explanation / Rationale

a) Is not correct. Static testing does not involve execution of the test object
b) Is not correct. Some static tests involve the use of a tool, especially static analysis, but reviews (such as the activity described here) do not necessarily involve the use of a tool
c) Is not correct. The review activity described here is part of a static test, but defects found in static tests are usually cheaper than those found in dynamic testing
d) Is correct. Static testing does not involve execution of the test object

Explanation / Rationale

a) Is not correct. Based on definition of equivalence partition
b) Is correct. Based on definition from Glossary
c) Is not correct. Based on Glossary definition of testware
d) Is not correct. Based on definition of test oracle

Explanation / Rationale

a) Is not correct. Statement coverage measures the percentage of statements exercised by test cases
b) Is correct. Statement testing exercises the executable statements in the code. Statement coverage is measured as the number of statements executed by the tests divided by the total number of executable statements in the test object, normally expressed as a percentage
c) Is not correct. The coverage does not measure pass/fail
d) Is not correct. It is a metric and does not provide true/false statements

Explanation / Rationale

a) Is not correct. Reviews should increase the quality of specifications, however the time required for development and testing should decrease
b) Is not correct. Detecting defects is generally easier earlier in the lifecycle
c) Is not correct. Reviews will result in fewer missed requirements and better communication between testers and developers, however this is not true for static analysis
d) Is correct. This is a benefit of static analysis

Explanation / Rationale

a) Is not correct. This activity is performed during the test design activity (test design)
b) Is not correct. This activity is performed during the test implementation activity (test implementation)
c) Is not correct. This activity is performed during the test completion activity (test completion)
d) Is correct. This activity is performed during the test analysis activity (test analysis)

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

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

Explanation / Rationale

Traceability assists with:

• Selecting regression tests in terms of analyzing the impact of changes (1D)
• Evaluating completeness of test execution which makes testing auditable (2B)
• Identifying which user stories have open defect reports which improves understandability of test status reports to include status of test basis items (3A)
• Evaluating whether the number of tests for each requirement is consistent with the level of product risk which provides information to assess test process quality (i.e., alignment of test effort with risk) (4C)

Thus:
a) Is not correct
b) Is not correct
c) Is not correct
d) Is correct

Explanation / Rationale

The following partitions can be identified:

1. <= 50, boundary value 50
2. 51 – 55 boundary values 51, 55
3. 56 – 60 boundary values 56, 60
4. >=61 boundary value 61

Boundary value according to glossary V.3.2: A minimum or maximum value of an ordered equivalence partition.

Thus:
a) Is not correct. Does not include all necessary boundary values, but it includes additional values: 0, 49, and 59, which are not boundary values in this equivalence partition
b) Is not correct. Does not include all necessary boundary values. 51 and 55 are missing
c) Is not correct. Does not include necessary boundary values but it includes additional values: 49, 62, and 54, which are not boundary values in this equivalence partition
d) Is correct. includes all necessary boundary values

Explanation / Rationale

Given the annotated state model below:

The options achieve the following transition coverage:
a) Is not correct: OFF (2) WAIT (1) OFF (2) WAIT (3) TRICKLE (5) CHARGE (9) HIGH (10) CHARGE (7) LOW = 7 transitions (out of 10)
b) Is not correct: WAIT (3) TRICKLE (4) WAIT (1) OFF (2) WAIT (3) TRICKLE (5) CHARGE (7) LOW (8) CHARGE = 7 transitions (out of 10)
c) Is not correct: HIGH (10) CHARGE (7) LOW (8) CHARGE (6) TRICKLE (4) WAIT (3) TRICKLE (4) WAIT (3) TRICKLE = 6 transitions (out of 10)
d) Is correct: WAIT (3) TRICKLE (5) CHARGE (9) HIGH (10) CHARGE (6) TRICKLE (4) WAIT (1) OFF (2) WAIT = 8 transitions (out of 10)

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”
