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 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 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. 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

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

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 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

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. 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. 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. 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. 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. System testing does not test interfaces between components and interactions between different parts of the system; this is a target of integration tests
b) Is correct. Examples of work products that can be used as a test basis for component testing include detailed design, code, data model, component specifications. Examples of work products for system testing include system and software requirement specifications (functional and non-functional) use cases
c) Is not correct. Component testing does not ONLY focus on functional characteristics
d) Is not correct. Component tests are also executed by developers, whereas system testing typically is the responsibility of (independent) testers

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

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. ‘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. 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. 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. 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. 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. 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 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 correct. Exploratory testing is a form of experience-based testing, which benefits from the skills and experience of the tester
b) b) Is not correct. Exploratory testing is useful to complement formal testing techniques
c) Is not correct. In session-based test management, exploratory testing is conducted within a defined time-box, and the tester uses a test charter containing test objectives to guide the testing
d) Is not correct. Exploratory testing can incorporate the use of other black-box, white-box, and experience-based techniques referenced in this syllabus

Explanation / Rationale

a) Is not correct. Estimates may be updated as more information becomes available, but estimates are needed to assist with planning before the testing starts
b) Is not correct. In the expert-based approach, the experts need to be experts in testing, not in using the test object
c) Is correct. Test Managers, who will be leading testers doing the testing, are considered experts in their respective areas and suitable for estimating the necessary resources needed
d) Is not correct. While it is useful to know the testing costs from previous projects, a more sophisticated approach is needed than simply taking an average of past projects (the new project may not be like the previous projects, e.g., it may be far larger or far smaller than previous projects)

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. 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

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 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

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 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. 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. While the given statement is true, the explanation is not. The relationship between statement and decision coverage is misrepresented
b) Is correct. Since any test case will cause the outcome of the “if” statement to be either TRUE or FALSE, by definition we achieved 50% decision coverage
c) Is not correct. A single test case can give more than 25% decision coverage, this means according to the statement above always 50 % decision coverage
d) Is not correct. The statement is specific and always true, because each test case achieves 50 % decision coverage

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 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. One of the major objectives of testing
b) Is not correct. Validation of the project plan would be a project management activity
c) Is not correct. Contradiction to principle #2; complete/exhaustive testing is not possible
d) Is not correct. “Comparing actual results with expected results” is a test performing activity, but not a test objective

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. 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 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. 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. 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
