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. 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

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 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. 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 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 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

Considering the scenario:

1. ‘testing is based on interface specifications’ – the test basis for integration testing includes interface specifications (along with communication protocol specification), while these are not included for any of the other test levels
2. ‘testing is focused on finding failures in communication’ - failures in the communication between tested components is included as a typical failure for integration testing, but failures in communication is not included for any of the other test levels
3. ‘the test approach uses both functional and structural test types’ - functional and structural test types are both included as possible approaches for integration testing, and would also be appropriate for any of the other test levels, although they are only otherwise explicitly mentioned in the syllabus for system testing

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

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 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. 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. 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 correct. This information has been defined earlier in the test project
b) Is not correct. This information is included in a test report: information on what occurred during a test period
c) Is not correct. This information is included in a test report:

• Status of testing and product quality with respect to the exit criteria or definition of done
• Metrics of defects, test cases, test coverage, activity progress, and resource consumption

d) Is not correct. This information is included in a test report: Information and metrics to support recommendations and decisions about future actions, such as an assessment of defects remaining, the economic benefit of continued testing, outstanding risks, and the level of confidence in the tested software

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

Proposed test case covers all five possible single valid transitions in the given state diagram (S1->S2, S2->S1, S2->S3, S3->S2, and S3->S1).

Thus:
a) Is not correct. Because no invalid transitions are covered
b) Is correct. Because all valid transitions are covered
c) Is not correct. Because all valid transitions are covered
d) Is not correct. Because the test cases do not have pairs of transitions specified

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. 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 correct. Percentage of test cases prepared is a common metric during test preparation while percentage of test cases passed, failed, not run, etc., are common during test execution
b) Is not correct. Defect reports are typically filed during test execution, based on failures found
c) Is not correct. Test environment preparation is part implementation and would generally be complete before test execution
d) Is not correct. Defects are typically reported during test execution, based on failures found, so the cost to find the next defect is available during test execution only

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. 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

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 correct. A crash is clearly noticeable by the user
b) Is not correct. This is a defect, not a failure since there is something wrong in the code. It may not result in a visible or noticeable failure, for example if the changes in the source code file are only in comments
c) Is not correct. The use of wrong input variables may not result in a visible or noticeable failure, for example if nobody uses this particular algorithm; or if the wrong input variable has a similar value to the correct input variable; or if the FALSE result of the algorithm is not used
d) Is not correct. This type of fault will not necessarily lead to a failure; for example, if no one uses this special algorithm

Explanation / Rationale

This question is looking for bad application of product risk analysis.

a) Is not correct. As we are told security flaws have a particularly high impact, their risk level will be higher, and thus we have prioritized the security testing ahead of some other testing. Thus, product risk analysis has influenced the testing properly.
b) Is correct. As less defects than expected have been found in the network module, the perceived risk in this area should be lower, and so less testing should be focused on this area, NOT additional testing. Thus, product risk analysis has NOT CORRECTLY influenced the testing in this situation
c) Is not correct. Because the users had problems with the user interface of the previous system, there is now high awareness of the risk associated with the user interface, which has resulted in additional usability testing being planned. Thus, product risk analysis has properly influenced the thoroughness and scope of testing
d) Is not correct. As the time needed to load web pages has been identified as crucial to the success of the new website, the performance of the website should be considered a risk, and the employment of an expert in performance testing helps to mitigate this risk. Thus, product risk analysis has properly influenced the testing

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. 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

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

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 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. 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

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. 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 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. 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. 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 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. 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. 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. 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. Static testing does not involve execution of the test object
b) Is not correct. Some static tests involve the use of a tool, especially static analysis, but reviews (such as the activity described here) do not necessarily involve the use of a tool
c) Is not correct. The review activity described here is part of a static test, but defects found in static tests are usually cheaper than those found in dynamic testing
d) Is correct. Static testing does not involve execution of the test object

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
