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. 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. 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 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

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

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

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

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. 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

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 correct. The statement is true. Achieving 100% decision coverage guarantees 100% statement coverage
b) Is not correct. The statement is false because achieving 100 % statement coverage does not in any case mean that the decision coverage is 100%
c) Is not correct. The statement is false because we can only do statements about 100% values
d) Is not correct. The statement is false

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. A path through source code is one potential route through the code from the entry point to the exit point that could exercise a range of decision outcomes. Two different paths may exercise all but one of the same decision outcomes, and by just changing a single decision outcome a new path is followed. Test cases that would achieve decision coverage are typically a tiny subset of the test cases that would achieve path coverage. In practice, most non-trivial programs (and all programs with unconstrained loops, such as ‘while’ loops) have a potentially infinite number of possible paths through them and so measuring the percentage covered is practically infeasible
b) Is not correct. Coverage of business flows can be a focus of use case testing, but use cases rarely cover a single component. It may be possible to cover the decisions within business flows, but only if they were specified in enough detail, however this option only suggests coverage of “business flows” as a whole. Even if business flows would cover some decisions, the measure “Decision Coverage” don’t measure the percentage of business flows, but the percentage of decision outcomes exercised by the business flows
c) Is not correct. Achieving full decision coverage does require all ‘if’ statements to be exercised with both true and false outcomes, however, there are typically several other decision points in the code (e.g., ‘case’ statements and the code controlling loops) that also need to be taken into consideration when measuring decision coverage
d) Is correct. Decision coverage is a measure of the proportion of decision outcomes exercised (normally presented as a percentage)

Explanation / Rationale

Product risks exist when a work product may fail to satisfy legitimate needs, while project risks are situations that could have a negative impact on the project’s ability to achieve its objectives. So:

A. Incorrect totals on screens = product risk
B. Change to acceptance criteria during acceptance testing = project risk
C. Users find the soft keyboard too hard to use with your app = product risk
D. System responds too slowly to user input during search string entry = product risk
E. Testers not allowed to report test results in daily standup meetings = project risk

Thus:
a) Is not correct. This list is entirely backwards
b) Is correct
c) Is not correct. While E is about product quality and product risks, the failure to communicate test results is a project risk per the syllabus
d) Is not correct. Product risks can be functional and non-functional, so d is also a product risk

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 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 (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

a) Is not correct. The book provides general guidance, and is not a formal requirements document, a specification, or a set of use cases, user stories, or business processes
b) Is not correct. While you could consider the list as a set of test charters, it more closely resembles the list of test conditions
c) Is correct. The list of user interface best practices is the list of test conditions
d) Is not correct. The tests are not focused on failures that could occur, but rather on knowledge about what is important for the user, in terms of usability

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

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

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. 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. During planning it is decided whether checklists are used. The preparation of the checklists is not part of the planning. In addition, the reviewers are neither involved in the planning, nor responsible for the creation of the checklists
b) Is not correct. During issue communication, any potential defects that have been identified in the individual review are communicated. The completion of checklists by the reviewers already takes place, if at all, during individual review
c) Is not correct. During review session, the reviewers communicate any potential defects of the work product that they did identify during the individual review. Defect reports are only created during the fixing and reporting activity
d) Is correct. Initiating the review (“Kick-off”) involves distributing the work product and other materials, like checklists

Explanation / Rationale

a) Is not correct. If inadequate developer testing were the problem, the confirmation test would not pass in step 3
b) Is not correct. The same tester who successfully performed the confirmation test in step 3 is repeating it in step 5
c) Is correct. Configuration management maintains the integrity of the software. If a test that passes in step 3 fails in step 5, then something is different between those two steps. One possible difference is the test object, the option listed here. Another possible difference is the between the development environment and the test environment, but that is not an option listed here
d) Is not correct. If the developers were not fixing the defect, the confirmation test would not pass in step 3

Explanation / Rationale

The correct pairings of test activities and test tools are:

1. Performance measurement and dynamic analysis – (b) Dynamic analysis tools
2. Test execution and logging – (a) Code coverage tools
3. Management of testing and testware – (d) Defect management tools
4. Test design – (c) Test data preparation tools

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

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

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

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

The correct pairings of examples to entry and exit criteria are:

• Entry criteria

o (3) The trading performance test environment has been designed, set-up and verified – example of the need for a test environment to be ready before testing can begin
o (5) The autopilot design specifications have been reviewed and reworked – example of the need for the test basis to be available before testing can begin
o (6) The tax rate calculation component has passed unit testing – example of the need for a test object to have met the exit criteria for a prior level of testing before testing can begin

• Exit criteria

o (1) The original testing budget of $30,000 plus contingency of $7,000 has been spent – example of spending the testing budget being a signal to stop testing
o (2) 96% of planned tests for the drawing package have been executed and the remaining tests are now out of scope – example of all the planned tests being run being a signal to stop testing (normally used alongside the exit criteria on outstanding defects remaining)
o (4) Current status is no outstanding critical defects and two high-priority ones – example of the number of outstanding defects achieving a planned limit being a signal to stop testing (normally used alongside the exit criteria on planned tests being run).

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

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

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 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 test result is given in the short summary
b) Is correct. When testing different versions of software, identifying information is necessary
c) Is not correct. You are just writing the defect report; hence, the status is automatically open
d) Is not correct. This information is useful for the tester but does not need to be included in the defect report

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:

• No sale completed (0.0 gallons)
• A valid sale occurs (0.1 to 50.0 gallons)
• An invalid amount is selected (50.1 or more gallons)

Thus:
a) Is correct. This set of input values has exactly one test per equivalence partition
b) Is not correct. This set of input values has does not cover the invalid amount partition
c) Is not correct. This set of input values has two tests for the valid sale equivalence partition, which is not the minimum
d) Is not correct. This set of input values covers the three-point boundary values for the two boundaries, not the minimum number required to cover the equivalence partitions

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. 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 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
