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. 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. 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. 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 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 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. 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

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

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. 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. 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

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. 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. 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

For the input equivalence partitions given, the above used boundary value technique yields the following 8 coverage items:

10°C, 11°C, 15°C, 16°C, 19°C, 20°C, 22°C, 23°C.

Hence, the options have the following boundary value coverage:
a) Is not correct. 4 out of 8 (11, 20 ,22 and 23)
b) Is not correct. 3 out of 8 (15, 19 and 23)
c) Is correct. 5 out of 8 (10, 16, 19, 22 and 23)
d) Is not correct. 3 out of 8 (15, 19 and 22)

Explanation / Rationale

There is at least one test for each column in the decision table. However, column one requires two tests, one where the account is invalid and another where the account is valid, but the password is invalid, so the minimum number of tests is four.

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

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

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

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 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

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

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 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

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. 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. 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 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. 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. 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

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. 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 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

Considering the attributes:

• There is a role of a scribe – specified for walkthroughs, technical reviews, and inspections; thus, the reviews being performed cannot be informal reviews
• The purpose is to detect potential defects – the purpose of detecting potential defects is specified for all types of review.
• The review meeting is led by the author – this is not allowed for inspections and is typically not the author for technical reviews, but is part of walkthroughs, and allowed for informal reviews
• Reviewers find potential issues by individual review - all types of reviews can include individual review (even informal reviews)
• A review report is produced - all types of reviews can produce a review report, although it would be less likely for an informal review

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

Explanation / Rationale

a) Is correct. This is maintainability testing, not maintenance testing
b) Is not correct. This is a trigger for maintenance testing: Operational tests of the new environment as well as of the changed software
c) Is not correct. This is the trigger for maintenance testing: testing restore/retrieve procedures after archiving for long retention periods
d) Is not correct. This is the trigger for maintenance testing: Reactive modification of a delivered software product to correct emergency defects that have caused actual failures

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)
