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. Structure-based, or white-box techniques are based on an analysis of the architecture, detailed design, internal structure, or the code of the test object
b) Is correct. Behavior-based, or black-box techniques are based on an analysis of the appropriate test basis (e.g., formal requirements documents, specifications, use cases, user stories, or business processes), which describe functional and non-functional behavior
c) Is not correct. Experience-based techniques leverage the experience of developers, testers, and users to determine what should be tested
d) Is not correct. Error guessing is a type of experience-based testing, which is not black-box

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. 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

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. Only two of the equivalence partitions are covered in this set of tests
b) Is not correct. Each of those four boundary values are included in this set of tests, but the question asked for equivalence partition coverage with minimal tests, so either 0.5 or 25.0 should be dropped
c) Is correct. Each of these three equivalence partitions are covered in this set of tests
d) Is not correct. Only one of those equivalence partitions is covered by this test

Explanation / Rationale

a) Is not correct. While recognizing different kinds of failures is a benefit of tester independence, in the scenario here no code yet exists that can fail, and the problem is that the developer and product owner are both assuming different things about the acceptance criteria
b) Is not correct. Developers losing a sense of responsibility for quality is a drawback, not a benefit
c) Is not correct. While the effect of the discovery of this disagreement is the earlier removal of the defect, prior to coding, defects can be discovered early by various people, not just independent testers
d) Is correct. Challenging stakeholder assumptions is a benefit of tester independence, and here the developer and product owner are both assuming different things about the acceptance criteria

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

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 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

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

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 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

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. 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

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. Analyzing a defect is part of debugging, not testing
b) Is correct. Creating test data is a test implementation task
c) Is not correct. While a tester may need to identify a test item’s version for results reporting purposes, assigning a test item’s version is part of configuration management
d) Is not correct. Writing a user story is not a testing activity and should be done by the product owner

Explanation / Rationale

a) Is not correct. Statement 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. 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. Although the description of regression testing is largely correct, the description of confirmation testing (which should be testing a defect has been fixed) is not correct
b) Is correct. The descriptions of both confirmation and regression testing match the intent of those in the syllabus
c) Is not correct. Although the description of regression testing is largely correct, the description of confirmation testing (re-running all previously run tests to get the same results) is not correct, as the purpose of confirmation testing is to check that tests that previously failed now pass (the fix worked)
d) Is not correct. Although the description of confirmation testing is largely correct, the description of regression testing (re-running tests that previously failed) is not correct (this is a more detailed description of confirmation testing)

Explanation / Rationale

a) Is correct. Making decisions about what to test are documented in the test plan. This means when you are planning the test and there are budget limitations, prioritizing is needed; what should be tested and what should be omitted
b) Is not correct. Test monitoring and control
c) Is not correct. Common test metrics
d) Is not correct. It is a part of test analysis

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

Explanation / Rationale

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. 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 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 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. Contradiction to principle 3: “Early testing saves time and money”
b) Is correct. This is one objective of testing
c) Is not correct. Principle #2 states that exhaustive testing is impossible, so one can never prove that all defects were identified
d) Is not correct. To make an assessment whether a defect will cause a failure or not, one must detect the defect first. Saying that no remaining defect will cause a failure implicitly means that all defects were found. This again contradicts principle #2

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

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

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

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

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. R4 is dependent on R2, so R2 should be tested before R4
b) Is not correct. R4 is dependent on R2, R5 and R6, so R5 and R6 should be tested before R4
c) Is correct. The tests are specified in a sequence that takes the dependencies into account
d) Is not correct. R2 is dependent on R3, so R3 should be tested before R2

Explanation / Rationale

There are three equivalence partitions:

• No sale completed (0.0 gallons)
• A valid sale occurs (0.1 to 50.0 gallons)
• An invalid amount is selected (50.1 or more gallons)

Thus:
a) Is correct. This set of input values has exactly one test per equivalence partition
b) Is not correct. This set of input values has does not cover the invalid amount partition
c) Is not correct. This set of input values has two tests for the valid sale equivalence partition, which is not the minimum
d) Is not correct. This set of input values covers the three-point boundary values for the two boundaries, not the minimum number required to cover the equivalence partitions

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
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 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. 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
