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. Incremental development involves establishing requirements, designing, building, and testing a system in pieces
b) Is not correct. This is a sequential model
c) Is not correct. This describes the waterfall model
d) Is not correct. Testing alone is not an increment/additional step in the development

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. While this information is useful for developers, it does not provide managers with a sense of the impact on product quality
b) Is not correct. This summary does not provide developers or managers with the necessary information and attacks the developers
c) Is not correct. This summary does not provide developers or managers with the necessary information and attacks the developers
d) Is correct. This summary gives a good sense of the failure and its impact

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

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

Explanation / Rationale

Test 01.001 must come first, followed by 01.002, to satisfy dependencies. Afterwards, 01.004 and 01.003 should be run in either order, followed by 01.005, to satisfy priority.
Thus:
a) Is not correct
b) Is correct
c) Is not correct
d) Is not correct

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

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

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

Explanation / Rationale

Considering the potential inconsistencies:

• 6-10 – If librarians should get system responses within 5 seconds, it is NOT inconsistent for borrowers to get system responses within 3 seconds.
• 6-15 - If librarians should get system responses within 5 seconds, it is inconsistent for all users to get system responses within 3 seconds.
• 7-12 – If borrowers can borrow a maximum of 3 books at one time it is NOT inconsistent for them to also reserve books (if they are on-loan).
• 9-11 – If a borrower can be fined for failing to return a book within 3 weeks it is inconsistent for them to also be allowed to borrow a book at no cost for a maximum of 4 weeks – as the length of valid loans are different.

Of the potential inconsistencies, 6-15 and 9-11 are valid inconsistencies.

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

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. 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. 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

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

Explanation / Rationale

The test cases should be scheduled in priority order, but the schedule must also take account of the dependencies.

The two highest priority test cases (TC1 and TC3) are both dependent on TC4, so the first three test cases should be scheduled as either TC4 – TC1 – TC3 or TC4 – TC3 – TC1 (we have no way to discriminate between TC1 and TC3).
Next, we need to consider the remaining medium priority test case, TC6. TC6 is dependent on TC5, but TC5 is dependent on TC2, so the next two three cases must be scheduled as
TC2 – TC5 – TC6.
This means there are two possible optimal schedules:

• TC4 – TC1 – TC3 – TC2 – TC5 – TC6 or
• TC4 – TC3 – TC1 – TC2 – TC5 – TC6

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

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

Explanation / Rationale

a) Is not correct. Testing is context dependent, regardless of it being manual or automated (principle #6), but does not result in detecting a decreasing number of faults as described above
b) Is not correct. Exhaustive testing is impossible, regardless of the amount of effort put into testing (principle #2)
c) Is correct. Principle #5 says “If the same tests are repeated over and over again, eventually these tests no longer find any new defects. To detect new defects, existing tests and test data may need changing, and new tests may need to be written.” Automated regression testing of the same test cases will not bring new findings
d) Is not correct. ”Defect cluster together” (principle #4). A small number of modules usually contain most of the defects, but this does not mean that fewer and fewer defects will be found

Explanation / Rationale

a) Is not correct. It is described that the software architect must have completed the system specification
b) Is not correct. ‘Checklist-based’, last sentence it is documented that you should also look for defects outside the checklist
c) Is not correct. It is described: every reviewer did his review done comment
d) Is correct. It is described that a checklist is available, but who provides the checklist?

Explanation / Rationale

Performance testing is a test type, not a test level. Component testing focuses on defects in separately testable modules or objects, integration testing on defects in interfaces and interactions, system testing on defects in the whole test object, and acceptance testing is not typically focused on identifying defects.

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

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

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

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

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. 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

Explanation / Rationale

a) Is not correct. Relevant for integration testing
b) Is not correct. Relevant for component testing
c) Is correct. For acceptance testing, tests are designed to cover all workflows defined in the functional requirements documents.
d) Is not correct. Relevant for system testing

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 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

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

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

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

Explanation / Rationale

a) Is not correct. Risk is determined by considering a combination of the likelihood of problem situations and the harm that may result from them but cannot be calculated by adding these together (the probability would be in the range 0 to 1 and the harm could be in dollars)
b) Is not correct. Risk is determined by considering a combination of a likelihood and an impact. This definition only considers likelihood and chance (both forms of probability) with no consideration of the impact (or harm)
c) Is correct. See reasons from incorrect answers
d) Is not correct. Risk is determined by considering a combination of a likelihood and an impact. This definition only considers hazards and losses (a hazard is a bad event, like a risk, while loss is a form of impact) with no consideration of the likelihood (or probability)

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

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. 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 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. 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 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 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

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
