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. 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 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 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

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. 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. 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 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. 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. 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

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

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. Informal review does not use a formal process
b) Is not correct. Use of checklists are optional
c) Is correct. Inspection is a formal process based on rules and checklists
d) Is not correct. Does not explicitly require a formal process and the use of checklists is optional

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 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

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. 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 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. 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

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

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. 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. 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. 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 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. 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

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 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. 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

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. 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. 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. 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. 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 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. 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

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 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. 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. 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
