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. 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

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)

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 correct pairing of descriptions with the different categories of test techniques is:

• Black-box test techniques
Deviations from the requirements are checked (4) User stories are used as the test basis (5)
• White-box test techniques
Coverage is measured based on a selected structure of the test object (1) The processing within the test object is checked (2)
• Experience-based test techniques
Tests are based on defects’ likelihood and their distribution (3)

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

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

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 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. One too few (see the four correct partitions in the correct answer)
b) Is not correct. One too much (see the four correct partitions in the correct answer)
c) Is not correct. Two too few (see the four correct partitions in the correct answer)
d) Is correct. The 4 equivalence partitions correspond to the description in the question, i.e., at least one test case must be created for each equivalence partition:

1. Equivalence partition: 0 ≤ employment time ≤ 2
2. Equivalence partition: 2 < employment time < 5
3. Equivalence partition: 5 ≤ employment time ≤ 10
4. Equivalence partition: 10 < employment time

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. ‘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”

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

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

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. 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

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. Structure-based, or white-box techniques are based on an analysis of the architecture, detailed design, internal structure, or the code of the test object
b) Is correct. Behavior-based, or black-box techniques are based on an analysis of the appropriate test basis (e.g., formal requirements documents, specifications, use cases, user stories, or business processes), which describe functional and non-functional behavior
c) Is not correct. Experience-based techniques leverage the experience of developers, testers, and users to determine what should be tested
d) Is not correct. Error guessing is a type of experience-based testing, which is not black-box

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

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 not correct. Regression testing does not check successful implementation of corrections and confirmation testing does not check for side effects
b) Is not correct. The statement about confirmation testing should be about regression testing
c) Is correct. See reasons from incorrect answers
d) Is not correct. Testing new functionality is not regression testing

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

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. Statement testing exercises the executable statements in the code, which might result in the absence of certain greetings not being tested
b) Is not correct. Unless the test charter specifically mentioned testing both the presence and the absence of each type of greeting, coverage can be difficult to assess for an exploratory test
c) Is not correct. State transition testing is useful for situations where the test object responds differently to an input depending on current conditions or previous history, but in this case the test object must decide whether the current date matches a particular milestone and thus whether to display the relevant greeting
d) Is correct. Decision testing involves test cases that follow the control flows that occur from a decision point, which in this case would be deciding whether a greeting should or should not be given

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)

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. 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

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. 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. 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

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 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 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 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. 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

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

Explanation / Rationale

The correct pairing of test activities and tasks is:

A. Test design – (2) Identifying test data to support the test cases
B. Test implementation – (3) Prioritizing test procedures and creating test data
C. Test execution – (4) Analyzing discrepancies to determine their cause
D. Test completion – (1) Entering change requests for open defect reports

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

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. While impact analysis is useful during maintenance testing it is not necessary for confirmation testing since confirmation testing is on the intended effects of a bug fix or other change
b) Is not correct. Confirmation and regression testing are two separate activities, and confirmation testing is not part of system design
c) Is correct. Impact analysis can be used to select regression tests for maintenance testing
d) Is not correct. Confirmation testing is not part of impact analysis, though confirmation testing will typically happen during maintenance testing

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

Explanation / Rationale

a) Is correct. If the expected security features are not supported by the system architecture, then the system could be seriously flawed. As the system being produced is the problem here, it is a product risk
b) Is not correct. If the developers run over budget, or run out of time, that is a problem with the running of the project – it is a project risk
c) Is not correct. If the test cases do not provide full coverage of the requirements, this means the testing may not fulfil the requirements of the test plan – it is a project risk
d) Is not correct. If the test environment is not ready, this means the testing may not be done, or it may have to be done on a different environment and it is impacting how the project is run – it is a project risk
