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

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

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. 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. 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

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

Each transition must be traversed at least once. To do so, the first test can cover the happy path, a successful purchase, the next test cancels, or timeout from waiting for pumping, the next test cancels, or timeout from waiting for fuel type, and the last test the insertion of an invalid credit card. While the order is immaterial, fewer than four tests fail to cover one of the transitions inbound to waiting for customer or violates the rules about where a test starts or ends. More than four tests include tests that re-traverse already-covered transitions.

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

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. 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

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

a) Is not correct. Traceability will allow existing test cases to be linked with updated and deleted requirements (although there is no support for new requirements), but it will not help with the automation of maintenance testing
b) Is correct. If all test cases are linked with requirements, then whenever a new test case (with traceability) is added, it is possible to see if any previously uncovered requirements are covered by the new test case
c) Is not correct. Traceability between the test basis and test artifacts will not provide information on which testers found high-severity defects, and, even if this information could be determined, it would be of limited value
d) Is not correct. Traceability can help with identifying test cases affected by changes, however areas impacted by side-effects would be the focus of regression testing

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. 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 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. 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

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. ‘Beware of the pesticide paradox’ is concerned with re-running the same tests and their fault-finding effectiveness decreasing
b) Is not correct. This testing principle is concerned with performing testing differently based on the context (e.g., games vs safety-critical)
c) Is not correct. This testing principle is concerned with the difference between a tested and fixed system and a validated system. No ‘errors’ does not mean the system is fit for use
d) Is correct. If clusters of defects are identified (areas of the system containing more defects than average), then testing effort should be focused on these areas

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. 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. 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. 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 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. 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

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 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 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. 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. 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. 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

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

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

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. 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. error guessing is not a usability technique for guessing how users may fail to interact with the test object
b) Is not correct. Although a tester who used to be a developer may use their personal experience to help them when performing error guessing, the technique is not based on prior knowledge of development
c) Is correct. The basic concept behind error guessing is that the tester tries to guess what mistakes may have been made by the developer and what defects may be in the test object based on past-experience (and sometimes checklists)
d) Is not correct. Duplicating the development task has several flaws that make it impractical, such as the requirement for the tester to have equivalent skills to the developer and the time involved in performing the development. It is not error guessing

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 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. 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

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

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. This is an objective listed
b) Is not correct. This is debugging
c) Is not correct. This is an activity within the test execution group of activities within the test process
d) Is not correct. This is part of debugging
