Q42. Which of the following statements is true?

A defect does not always produce a failure, while a bug always produces a failure

A defect may cause a failure which, when occurring, always causes an error

Failures can be caused by defects, but also by environmental conditions

Bugs are defects found during component testing, while failures are defects found at higher test levels

Failures can be caused by defects, but also by environmental conditions. A failure is an event in which the software system does not perform a required function or performs a function incorrectly, according to the expected behavior. A defect is a flaw in the software system or a deviation from the requirements or the specifications, that may cause a failure. However, not all failures are caused by defects, as some failures may be caused by environmental conditions, such as hardware malfunctions, network interruptions, power outages, incompatible configurations, etc. Environmental conditions are factors that affect the operation of the software system, but are not part of the software system itself. The other statements are false, because:
A defect does not always produce a failure, while a bug always produces a failure. This statement is false, because a defect may or may not produce a failure, depending on the inputs, the outputs, the states, or the scenarios of the software system, and a bug is just another term for a defect, so it has the same possibility of producing a failure as a defect. For example, a defect in a rarely used feature or a hidden branch of the code may never produce a failure, while a defect in a frequently used feature or a critical path of the code may produce a failure often. A bug is not a different concept from a defect, but rather a synonym or a colloquial term for a defect, so it has the same definition and implications as a defect.
A defect may cause a failure which, when occurring, always causes an error. This statement is false, because an error is not a consequence of a failure, but rather a cause of a defect. An error is a human action or a mistake that produces a defect in the software system, such as a typo, a logic flaw, a requirement misunderstanding, etc. An error is not observable in the software system, but rather in the human mind or the human work products, such as the code, the design, the documentation, etc. A failure is not a cause of an error, but rather a result of a defect, which is a result of an error. For example, an error in the code may cause a defect in the software system, which may cause a failure in the software behavior.
Bugs are defects found during component testing, while failures are defects found at higher test levels. This statement is false, because bugs and failures are not different types of defects, but rather different terms for defects and their manifestations. As mentioned before, bugs are just another word for defects, and failures are the events in which the software system does not perform as expected due to defects. Bugs and failures can be found at any test level, not only at component testing or higher test levels. Test levels are the stages of testing that correspond to the levels of integration of the software system, such as component testing, integration testing, system testing, and acceptance testing. Defects and failures can occur and be detected at any test level, depending on the test objectives, the test basis, the test techniques, and the test environment.

Q43. Which of the following statements about white-box test techniques is true?

Achieving full statement coverage and full branch coverage for a software product means that such software product has been fully tested and there are no remaining bugs within the code

Code-related white-box test techniques are not required to measure the actual code coverage achieved by black-box testing, as code coverage can be measured using the coverage criteria associated with black-box test techniques

Branch coverage is the most thorough code-related white-box test technique, and therefore applicable standards prescribe achieving full branch coverage at the highest safety levels for safety-critical systems

Code-related white-box test techniques provide an objective measure of coverage and can be used to complement black-box test techniques to increase confidence in the code

Q44. A company runs a pilot project for evaluation of a test automation tool. Which of the following is NOT a valid object of this pilot project?

Get familiar with the functionality and options of the tool

Check haw the tool fits to the existing test processes

Train all testers on using the tool

Decide upon standards for tool implementation

Q45. Which of the following statements is true?

In Agile software development, work product documentation tends to be lightweight and manual tests tend to be often unscripted as they are often produced using experience-based test techniques

Sequential development models impose the use of systematic test techniques and do not allow the use of experience-based test techniques

In Agile software development, the first iterations are exclusively dedicated to testing activities, as testing will be used to drive development, which will be performed in the subsequent iterations

Both in Agile software development and in sequential development models, such as the V-model, test levels tend to overlap since they do not usually have defined entry and exit criteria

Q46. Which one of the following statements correctly describes the term ‘debugging’?

There is no difference between debugging and testing.

Debugging is a confirmation activity that checks whether fixes resolved defects.

Debugging is the development activity that finds, analyses and fixes defects.

Debugging is of no relevance in Agile development.

Q47. The statement: “Test activities should start in the early stages of the lifecycle, adhering to the testing principle of early testing” is relevant to which of the recognized software development models?

Sequential development model.

Iterative development model.

Incremental development model.

All the above

Q48. During which main group of test activity are the following tasks performed?
* Checking test results and logs against specified coverage criteria.
* Assessing the level of component or system quality based on test results and logs.
* Determining whether more tests are needed.
Select the correct answer:

Test planning.

Test analysis.

Test design.

Test monitoring and control.

Q49. Which of the following statements about the value of maintaining traceability between the test basis and test work products is not true?

Traceability can be useful for assessing the impact of a change to a test basis item on the corresponding tests

Traceability can be useful for determining how many test basis items are covered by the corresponding tests

Traceability can be useful for determining the most suitable test techniques to be used in a testing project

Traceability can be useful to support the needs required by the auditing of testing

Traceability is the ability to trace the relationships between the items of the test basis, such as the requirements, the design, the risks, etc., and the test artifacts, such as the test cases, the test results, the defects, etc. Traceability can provide various benefits for the testing process, such as improving the test coverage, the test quality, the test efficiency, and the test communication. However, not all the statements given are true about the value of maintaining traceability between the test basis and test work products. The statement that is not true is option C, which says that test objectives should be the same for all test levels, although the number of tests designed at various levels can vary significantly. This statement is false, because test objectives are the goals or the purposes of testing, which can vary depending on the test level, the test type, the test technique, the test environment, the test stakeholder, etc. Test objectives can be defined in terms of the test basis, the test coverage, the test quality, the test risk, the test cost, the test time, etc. Test objectives should be specific, measurable, achievable, relevant, and time-bound, and they should be aligned with the project objectives and the quality characteristics. Test objectives should not be the same for all test levels, as different test levels have different focuses, scopes, and perspectives of testing, such as component testing, integration testing, system testing, and acceptance testing. The other statements are true about the value of maintaining traceability between the test basis and test work products, such as:
Traceability can be useful for assessing the impact of a change to a test basis item on the corresponding tests: This statement is true, because traceability can help to identify which tests are affected by a change in the test basis, such as a new requirement, a modified design, a revised risk, etc., and to determine the necessary actions to update, re-execute, or re-evaluate the tests. Traceability can also help to estimate the effort, the cost, and the time needed to implement the change and to verify its impact on the software system.
Traceability can be useful for determining how many test basis items are covered by the corresponding tests: This statement is true, because traceability can help to measure the test coverage, which is the degree to which the test basis is exercised by the test cases. Traceability can help to identify which test basis items are covered, partially covered, or not covered by the tests, and to evaluate the adequacy, the completeness, and the effectiveness of the testing process. Traceability can also help to identify the gaps, the overlaps, or the redundancies in the test coverage, and to prioritize, optimize, or improve the test cases.
Traceability can be useful to support the needs required by the auditing of testing: This statement is true, because traceability can help to provide evidence, documentation, and justification for the testing activities, results, and outcomes. Traceability can help to demonstrate that the testing process follows the standards, the regulations, the policies, and the best practices that are applicable to the software system, the project, or the organization. Traceability can also help to verify that the testing process meets the expectations, the needs, and the satisfaction of the users and the stakeholders.

Q57. A Test Manager conducts risk assessment for a project. One of the identified risks is: The sub-contractor may fail to meet his commitment”. If this risk materializes. it will lead to delay in completion of testing required for the current cycle.
Which of the following sentences correctly describes the risk?

It is a product risk since any risk associated with development timeline is a product risk.

It is no longer a risk for the Test Manager since an independent party (the sub-contractor) is now managing it

It is a object risk since successful completion of the object depends on successful and timely completion of the tests

It is a product risk since default on part of the sub-contractor may lead to delay in release of the product

A product risk is a risk that affects the quality or timeliness of the software product being developed or tested1. Product risks are related to the requirements, design, implementation, verification, and maintenance of the software product2.
The risk of the sub-contractor failing to meet his commitment is a product risk, as it could cause a delay in the completion of the testing required for the current cycle, which in turn could affect the release date of the product. The release date is an important aspect of the product quality, as it reflects the customer satisfaction and the market competitiveness of the product3.
The other options are not correct because:
A . It is not true that any risk associated with development timeline is a product risk. Some risks could be project risks, which are risks that affect the management or control of the software project, such as budget, resources, schedule, or communication1. For example, a risk of losing a key project stakeholder is a project risk, not a product risk.
B . It is not true that the risk is no longer a risk for the Test Manager since an independent party is managing it. The Test Manager is still responsible for ensuring that the testing activities are completed according to the test plan and the quality objectives4. The Test Manager should monitor and control the sub-contractor’s performance and communicate with him regularly to identify and mitigate any potential issues or deviations5.
C . It is not clear what is meant by “object” in this option, but it could be interpreted as the software system under test or the test object6. In any case, the risk is not an object risk, as it does not affect the successful completion of the object, but rather the successful completion of the testing of the object. An object risk could be a risk that affects the functionality, reliability, usability, efficiency, maintainability, or portability of the software system under test2. For example, a risk of the software system having a high complexity or a low testability is an object risk, not a product risk.

I . Allows earlier detection and easier root cause analysis of integration problems and conflicting changes.
II . Removes the need for manual test analysis, design and execution.
Hi. Removes the dependency on automated regression packs when integrating larger systems, or components.
iv . Gives the development team regular feedback on whether the code is working.
Select the correct answer:

i and iv

i and ii

i and iii

iii and iv

Q61. A document descnbes the test procedures that have been derived for the identified test sets Among other things, the order in which the test cases in the corresponding test set are to be executed according to the dependencies described by preconditions and postconditions is specified This document is a typical work product produced as part of:

Test design.

Test analysis

Test Implementation.

Test monitoring and control

Q62. The acceptance criteria associated with a user story:

are often written in a rule-oriented format using the template referred to as “Given/When/Then”

are often documented following in rule-oriented format using the following template: “As a [role], I want [feature], so that I can [benefit]”

can be written in different formats and represent an aspect of a user story referred to as confirmation’ of the so called “3 C’s”

must be written in one of the two following formats: scenario-oriented or rule-oriented

Q63. Which of the following statements about estimation of the test effort is WRONG?

Once the test effort is estimated, resources can be identified and a schedule can be drawn up.

Effort estimate can be inaccurate because the quality of the product under tests is not known.

Effort estimate depends on the budget of the project.

Experience based estimation is one of the estimation techniques.

Effort estimate does not depend on the budget of the project, but rather on the scope, complexity, and quality of the software product and the testing activities1. Budget is a constraint that may affect the feasibility and accuracy of the effort estimate, but it is not a factor that determines the effort estimate. Effort estimate is the amount of work required to complete the testing activities, measured in terms of person-hours, person-days, or person-months2.
The other options are correct because:
A . Once the test effort is estimated, resources can be identified and a schedule can be drawn up, as they are interrelated aspects of the test planning process3. Resources are the people, tools, equipment, and facilities needed to perform the testing activities4. Schedule is the time frame and sequence of the testing activities, aligned with the project milestones and deadlines5.
B . Effort estimate can be inaccurate because the quality of the product under tests is not known, as it affects the number and severity of the defects that may be found and the rework that may be needed to fix them6. Quality is the degree to which the software product satisfies the specified requirements and meets the needs and expectations of the users and clients7.
D . Experience based estimation is one of the estimation techniques, which relies on the judgment and expertise of the testers and other project stakeholders to estimate the test effort based on similar projects or tasks done in the past. Experience based estimation can be useful when there is a lack of historical data, formal methods, or detailed information about the software product and the testing activities.
