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

The following partitions can be identified:

1. <= 50, boundary value 50
2. 51 – 55 boundary values 51, 55
3. 56 – 60 boundary values 56, 60
4. >=61 boundary value 61

Boundary value according to glossary V.3.2: A minimum or maximum value of an ordered equivalence partition.

Thus:
a) Is not correct. Does not include all necessary boundary values, but it includes additional values: 0, 49, and 59, which are not boundary values in this equivalence partition
b) Is not correct. Does not include all necessary boundary values. 51 and 55 are missing
c) Is not correct. Does not include necessary boundary values but it includes additional values: 49, 62, and 54, which are not boundary values in this equivalence partition
d) Is correct. includes all necessary boundary values

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. 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 not correct. This is a white-box test technique
b) Is not correct. This is a white-box test technique
c) Is not correct. This is an experience-based test technique
d) Is correct. Black-box test techniques are based on an analysis of the appropriate test basis (e.g., formal requirements documents, specifications, use cases, user stories)

Explanation / Rationale

a) Is correct. Incremental development involves establishing requirements, designing, building, and testing a system in pieces
b) Is not correct. This is a sequential model
c) Is not correct. This describes the waterfall model
d) Is not correct. Testing alone is not an increment/additional step in the development

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. 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

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 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

The following valid equivalence partitions can be identified:

1. Up to 1000 - Couch Potato!
2. Above 1000, up to 2000 - Lazy Bones!
3. Above 2000, up to 4000 - Getting There!
4. Above 4000, up to 6000 - Not Bad!
5. Above 6000 - Way to Go!

The sets of test inputs therefore cover the following partitions:
a) Is not correct. 0 (1), 1000 (1), 2000 (2), 3000 (3), 4000 (3) – 3 partitions (out of 5)
b) Is not correct. 1000 (1), 2001 (3), 4000 (3), 4001 (4), 6000 (4) – 3 partitions (out of 5)
c) Is not correct. 123 (1), 2345 (3), 3456 (3), 4567 (4), 5678 (4) – 3 partitions (out of 5)
d) Is correct. 666 (1), 999 (1), 2222 (3), 5555 (4), 6666 (5) – 4 partitions (out of 5)

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. See reason from correct answer
b) Is not correct. See reason from correct answer
c) Is correct. This is a case where the requirement gives an enumeration of discrete values. Each enumeration value is an equivalence class by itself; therefore, each will be tested when using equivalence partitioning test technique
d) Is not correct. See reason from correct answer

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. 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. 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. Statement coverage is a measure of the proportion of executable statements exercised by tests. The number of executable statements is often close to the number of lines of code minus the comments, but this option only talks about the number of lines of code exercised and not the proportion exercised
b) Is correct. Statement coverage is a measure of the proportion of executable statements exercised by tests (normally presented as a percentage)
c) Is not correct. Statement coverage is a measure of the percentage of executable statements exercised by tests, however many of the lines of source code are not executable (e.g., comments)
d) Is not correct. Statement coverage is a measure of the proportion of executable statements exercised by tests. This option only talks about the number of executable statements exercised and not the proportion (or percentage) exercised

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

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

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

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. 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. 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

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 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

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 correct. If the expected security features are not supported by the system architecture, then the system could be seriously flawed. As the system being produced is the problem here, it is a product risk
b) Is not correct. If the developers run over budget, or run out of time, that is a problem with the running of the project – it is a project risk
c) Is not correct. If the test cases do not provide full coverage of the requirements, this means the testing may not fulfil the requirements of the test plan – it is a project risk
d) Is not correct. If the test environment is not ready, this means the testing may not be done, or it may have to be done on a different environment and it is impacting how the project is run – it is a project risk

Explanation / Rationale

a) Is correct. 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. Exploratory testing is not suitable to speed up tests, which are already specified. It is most useful when there are few or inappropriate specified requirements or significant time pressure on testing
b) Is not correct. The absence of a test charter, which may have been derived from the test analysis, is a poor precondition for the use of exploratory testing
c) Is correct. Exploratory tests should be performed by experienced testers with knowledge of similar applications and technologies
d) Is not correct. Explorative testing alone is not suitable to provide evidence that the test was very intensive, instead the evidence is provided in combination with other test methods

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

a) Is correct. The statement is true. Achieving 100% decision coverage guarantees 100% statement coverage
b) Is not correct. The statement is false because achieving 100 % statement coverage does not in any case mean that the decision coverage is 100%
c) Is not correct. The statement is false because we can only do statements about 100% values
d) Is not correct. The statement is false

Explanation / Rationale

a) Is not correct. While impact analysis is useful during maintenance testing it is not necessary for confirmation testing since confirmation testing is on the intended effects of a bug fix or other change
b) Is not correct. Confirmation and regression testing are two separate activities, and confirmation testing is not part of system design
c) Is correct. Impact analysis can be used to select regression tests for maintenance testing
d) Is not correct. Confirmation testing is not part of impact analysis, though confirmation testing will typically happen during maintenance testing

Explanation / Rationale

a) Is not correct. The lack of familiarity of the requirements author with the fitness domain is a root cause
b) Is not correct. The lack of training of the tester in state transition testing was one of the root causes of the defect (the developer presumably created the defect, as well)
c) Is correct. The incorrect configuration data represents faulty software in the fitness tracker (a defect), that may cause failures
d) Is not correct. The lack of experience in designing user interfaces for wearable devices is a typical example of a root cause of a defect

Explanation / Rationale

Given the annotated state model below:

The options achieve the following transition coverage:
a) Is not correct: OFF (2) WAIT (1) OFF (2) WAIT (3) TRICKLE (5) CHARGE (9) HIGH (10) CHARGE (7) LOW = 7 transitions (out of 10)
b) Is not correct: WAIT (3) TRICKLE (4) WAIT (1) OFF (2) WAIT (3) TRICKLE (5) CHARGE (7) LOW (8) CHARGE = 7 transitions (out of 10)
c) Is not correct: HIGH (10) CHARGE (7) LOW (8) CHARGE (6) TRICKLE (4) WAIT (3) TRICKLE (4) WAIT (3) TRICKLE = 6 transitions (out of 10)
d) Is correct: WAIT (3) TRICKLE (5) CHARGE (9) HIGH (10) CHARGE (6) TRICKLE (4) WAIT (1) OFF (2) WAIT = 8 transitions (out of 10)

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. During planning it is decided whether checklists are used. The preparation of the checklists is not part of the planning. In addition, the reviewers are neither involved in the planning, nor responsible for the creation of the checklists
b) Is not correct. During issue communication, any potential defects that have been identified in the individual review are communicated. The completion of checklists by the reviewers already takes place, if at all, during individual review
c) Is not correct. During review session, the reviewers communicate any potential defects of the work product that they did identify during the individual review. Defect reports are only created during the fixing and reporting activity
d) Is correct. Initiating the review (“Kick-off”) involves distributing the work product and other materials, like checklists

Explanation / Rationale

Traceability assists with:

• Selecting regression tests in terms of analyzing the impact of changes (1D)
• Evaluating completeness of test execution which makes testing auditable (2B)
• Identifying which user stories have open defect reports which improves understandability of test status reports to include status of test basis items (3A)
• Evaluating whether the number of tests for each requirement is consistent with the level of product risk which provides information to assess test process quality (i.e., alignment of test effort with risk) (4C)

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

Explanation / Rationale

a) Is not correct. 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 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
