BCS ISTQB Certified Tester Foundation Level CTFL 4.0 Sample Questions (Q183-Q188):

NEW QUESTION # 183
Which of the following statements about how different types of test tools support testers is true?

  • A. The support offered by a continuous integration tool is often leveraged by testers to automatically generate test cases from a model
  • B. The support offered by a test data preparation tool is often leveraged by testers to run automated regression test suites
  • C. The support offered by a bug prediction tool is often used by testers to track the bugs they found
  • D. The support offered by a performance testing tool is often leveraged by testers to run load tests

Answer: D

Explanation:
The support offered by a performance testing tool is often leveraged by testers to run load tests, which are tests that simulate a large number of concurrent users or transactions on the system under test, in order to measure its performance, reliability, and scalability. Performance testing tools can help testers to generate realistic workloads, monitor system behavior, collect and analyze performance metrics, and identify performance bottlenecks. The other statements are false, because:
* A test data preparation tool is a tool that helps testers to create, manage, and manipulate test data, which are the inputs and outputs of test cases. Test data preparation tools are not directly related to running automated regression test suites, which are test suites that verify that the system still works as expected after changes or modifications. Regression test suites are usually executed by test execution tools, which are tools that can automatically run test cases and compare actual results with expected results.
* A bug prediction tool is a tool that uses machine learning or statistical techniques to predict the likelihood of defects in a software system, based on various factors such as code complexity, code churn, code coverage, code smells, etc. Bug prediction tools are not used by testers to track the bugs they found, which are the actual defects that have been detected and reported during testing. Bugs are usually tracked by defect management tools, which are tools that help testers to record, monitor, analyze, and resolve defects.
* A continuous integration tool is a tool that enables the integration of code changes from multiple developers into a shared repository, and the execution of automated builds and tests, in order to ensure the quality and consistency of the software system. Continuous integration tools are not used by testers to automatically generate test cases from a model, which are test cases that are derived from a representation of the system under test, such as a state diagram, a decision table, a use case, etc. Test cases can be automatically generated by test design tools, which are tools that support the implementation and maintenance of test cases, based on test design specifications or test models.

NEW QUESTION # 184
Which of the following statements best describes the difference between product risk and project risk in software testing?

  • A. Product risk refers to the risk associated with issues such as delays in work product deliveries, inaccurate estimates, while project risk refers to the risk associated with the project's schedule, budget, and resources.
  • B. Product risk and project risk are essentially the same and can be used interchangeably.
  • C. Product risk refers to the risk associated with delays in elements such as work product deliveries and inaccurate estimates, while project risk refers to the risk associated with issues such as user dissatisfaction.
  • D. Product risk refers to the risk associated with the project's schedule, budget, and resources, while project risk refers to the risk associated with the quality and functionality of the software product.

Answer: A

Explanation:
Product risk involves the potential issues that can affect the quality and functionality of the software product, such as defects, performance problems, and usability issues. Project risk, on the other hand, relates to the risks that can impact the project's schedule, budget, and resources, such as delays, cost overruns, and resource constraints. Understanding both types of risks is crucial for managing and mitigating potential problems in software projects.


NEW QUESTION # 185
Which of the following statements best describes the way in which decision coverage is measured?

  • A. It is not possible to accurately measure decision coverage.
  • B. Measured as the number of decision outcomes executed by the tests, divided by the total number of decision outcomes in the test object.
  • C. Measured as the number of statements executed by the tests, divided by the total number of executable statements in the code.
  • D. Measured as the number of lines of code executed by the tests, divided by the total number of lines of code in the test object.

Answer: B

Explanation:
Decision coverage, also known as branch coverage, is measured as the number of decision outcomes executed by the tests divided by the total number of decision outcomes in the test object. It ensures that every possible branch (true/false) decision in the code has been executed at least once.

NEW QUESTION # 186
The four test levels used in ISTQB syllabus are:
1. Component (unit) testing
2. Integration testing
3. System testing
4. Acceptance testing
An organization wants to do away with integration testing but otherwise follow V-model. Which of the following statements is correct?

  • A. It is allowed because integration testing is not an important test level arc! can be dispensed with.
  • B. It is not allowed as organizations can't change the test levels as these are chosen on the basis of the SDLC (software development life cycle) model
  • C. It is allowed as organizations can decide on men test levels to do depending on the context of the system under test
  • D. It is not allowed because integration testing is a very important test level and ignoring i: means definite poor product quality

Answer: B

Explanation:
The V-model is a software development life cycle model that defines four test levels that correspond to four development phases: component (unit) testing with component design, integration testing with architectural design, system testing with system requirements, and acceptance testing with user requirements. The V-model emphasizes the importance of verifying and validating each phase of development with a corresponding level of testing, and ensuring that the test objectives, test basis, and test artifacts are aligned and consistent across the test levels. Therefore, an organization that wants to follow the V-model cannot do away with integration testing, as it would break the symmetry and completeness of the V-model, and compromise the quality and reliability of the software or system under test. Integration testing is a test level that aims to test the interactions and interfaces between components or subsystems, and to detect any defects or inconsistencies that may arise from the integration of different parts of the software or system. Integration testing is essential for ensuring the functionality, performance, and compatibility of the software or system as a whole, and for identifying and resolving any integration issues early in the development process. Skipping integration testing would increase the risk of finding serious defects later in the test process, or worse, in the production environment, which would be more costly and difficult to fix, and could damage the reputation and credibility of the organization. Therefore, the correct answer is D.
The other options are incorrect because:
A . It is not allowed as organizations can decide on the test levels to do depending on the context of the system under test. While it is true that the choice and scope of test levels may vary depending on the context of the system under test, such as the size, complexity, criticality, and risk level of the system, the organization cannot simply ignore or skip a test level that is defined and required by the chosen software development life cycle model. The organization must follow the principles and guidelines of the software development life cycle model, and ensure that the test levels are consistent and coherent with the development phases. If the organization wants to have more flexibility and adaptability in choosing the test levels, it should consider using a different software development life cycle model, such as an agile or iterative model, that allows for more dynamic and incremental testing approaches.
B . It is not allowed because integration testing is not an important test level and can be dispensed with. This statement is false and misleading, as integration testing is a very important test level that cannot be dispensed with. Integration testing is vital for testing the interactions and interfaces between components or subsystems, and for ensuring the functionality, performance, and compatibility of the software or system as a whole. Integration testing can reveal defects or inconsistencies that may not be detected by component (unit) testing alone, such as interface errors, data flow errors, integration logic errors, or performance degradation. Integration testing can also help to verify and validate the architectural design and the integration strategy of the software or system, and to ensure that the software or system meets the specified and expected quality attributes, such as reliability, usability, security, and maintainability. Integration testing can also provide feedback and confidence to the developers and stakeholders about the progress and quality of the software or system development. Therefore, integration testing is a crucial and indispensable test level that should not be skipped or omitted.
C . It is not allowed because integration testing is a very important test level and ignoring it means definite poor product quality. This statement is partially true, as integration testing is a very important test level that should not be ignored, and skipping it could result in poor product quality. However, this statement is too strong and absolute, as it implies that integration testing is the only factor that determines the product quality, and that ignoring it would guarantee a poor product quality. This is not necessarily the case, as there may be other factors that affect the product quality, such as the quality of the requirements, design, code, and other test levels, the effectiveness and efficiency of the test techniques and tools, the competence and experience of the developers and testers, the availability and adequacy of the resources and environment, the management and communication of the project, and the expectations and satisfaction of the customers and users. Therefore, while integration testing is a very important test level that should not be skipped, it is not the only test level that matters, and skipping it does not necessarily mean definite poor product quality, but rather a higher risk and likelihood of poor product quality.

NEW QUESTION # 187
Which of the following is a test task that usually occurs during test implementation?

  • A. Archive the testware for use in future test projects
  • B. Gather the metrics that are used to guide the test project
  • C. Make sure the planned test environment is ready to be delivered
  • D. Find, analyze, and remove the causes of the failures highlighted by the tests

Answer: C

Explanation:
A test task that usually occurs during test implementation is to make sure the planned test environment is ready to be delivered. The test environment is the hardware and software configuration on which the tests are executed, and it should be as close as possible to the production environment where the software system will operate. The test environment should be planned, prepared, and verified before the test execution, to ensure that the test conditions, the test data, the test tools, and the test interfaces are available and functional. The other options are not test tasks that usually occur during test implementation, but rather test tasks that occur during other test activities, such as:
* Find, analyze, and remove the causes of the failures highlighted by the tests: This is a test task that usually occurs during test analysis and design, which is the activity of analyzing the test basis, designing the test cases, and identifying the test data. During this activity, the testers can use techniques such as root cause analysis, defect prevention, or defect analysis, to find, analyze, and remove the causes of the failures highlighted by the previous tests, and to prevent or reduce the occurrence of similar failures in the future tests.
* Archive the testware for use in future test projects: This is a test task that usually occurs during test closure, which is the activity of finalizing and reporting the test results, evaluating the test process, and identifying the test improvement actions. During this activity, the testers can archive the testware, which are the test artifacts produced during the testing process, such as the test plan, the test cases, the test data, the test results, the defect reports, etc., for use in future test projects, such as regression testing, maintenance testing, or reuse testing.
* Gather the metrics that are used to guide the test project: This is a test task that usually occurs during test monitoring and control, which is the activity of tracking and reviewing the test progress, status, and quality, and taking corrective actions when necessary. During this activity, the testers can gather the metrics, which are the measurements of the testing process, such as the test coverage, the defect density, the test effort, the test duration, etc., that are used to guide the test project, such as planning, estimating, scheduling, reporting, or improving the testing process.
