What is the best description of static analysis?
- A.
The analysis of batch programs
- B.
The reviewing of test plans
- C.
The analysis of program code or other software artifacts
- D.
The use of black-box testing
Correct Answer
C. The analysis of program code or other software artifactsExplanation
Static analysis refers to the process of analyzing program code or other software artifacts without actually executing the code. It involves examining the code to identify potential errors, bugs, or vulnerabilities. This analysis helps in finding issues such as coding errors, security vulnerabilities, performance problems, and adherence to coding standards. The purpose of static analysis is to improve software quality, enhance security, and reduce the likelihood of bugs and errors in the code. It is different from black-box testing, which involves testing the software from an external perspective without knowledge of its internal structure.Rate this question:

System test execution on a project is planned for eight weeks. After a week of testing, a tester suggests that the test objective stated in the test plan of 'finding as many defects as possible during system test' might be more closely met by redirecting the test effort according to which test principle?
- A.
Impossibility of exhaustive testing.
- B.
Importance of early testing.
- C.
The absence of errors fallacy.
- D.
Defect clustering.
Correct Answer
D. Defect clustering.Explanation
The tester suggests redirecting the test effort according to the test principle of defect clustering. Defect clustering is the principle that states that a small number of modules or areas in the system usually contain the majority of defects. By focusing the test effort on these specific modules or areas, the objective of finding as many defects as possible during system testing can be better met. This principle recognizes that not all parts of the system are equally likely to contain defects, and prioritizes testing in the areas that are more prone to defects.Rate this question:

Consider the following activities that might relate to configuration management: I. Identify and document the characteristics of a test item II. Control changes to the characteristics of a test item III. Check a test item for defects introduced by a change IV. Record and report the status of changes to test items V. Confirm that changes to a test item fixed a defect Which of the following statements is true?
- A.
Only I is a configuration management task.
- B.
All are configuration management tasks.
- C.
I, II and III are configuration management tasks.
- D.
I, II and IV are configuration management tasks.
Correct Answer
D. I, II and IV are configuration management tasks.Explanation
The correct answer is I, II and IV are configuration management tasks. This is because identifying and documenting the characteristics of a test item (I), controlling changes to the characteristics of a test item (II), and recording and reporting the status of changes to test items (IV) are all activities that fall under the scope of configuration management. These tasks involve managing and tracking changes made to test items, ensuring that they are properly documented and reported.Rate this question:

A test plan included the following clauses among the exit criteria: # System test shall continue until all significant product risks have been covered to the extent specified in the product risk analysis document. # System test shall continue until no must-fix defects remain against any significant product risks specified in the product risk analysis document. During test execution, the test team detects 430 must-fix defects prior to release and all must-fix defects are resolved. After release, the customers find 212 new defects, none of which were detected during testing. This means that only 67% of the important defects were found prior to release, a percentage which is well below average in your industry. You are asked to find the root cause for the high number of field failures. Consider the following list of explanations: I. Not all the tests planned for the significant product risks were executed. II. The organization has unrealistic expectations of the percentage of defects that testing can find. III. A version-control issue has resulted in the release of a version of the software that was used during early testing. IV. The product risk analysis failed to identify all the important risks from a customer point of view. V. The product risk analysis was not updated during the project as new information became available. Which of the following statements indicate which explanations are possible root causes?
- A.
II, III and IV are possible explanations, but I and V are not possible.
- B.
All five are possible explanations.
- C.
I, IV and V are possible explanations, but II and III are not possible.
- D.
III, IV and V are possible explanations, but I and II are not possible.
Correct Answer
C. I, IV and V are possible explanations, but II and III are not possible.Explanation
The correct answer is I, IV and V are possible explanations, but II and III are not possible. This is because the statement mentions that not all tests planned for significant product risks were executed (explanation I), the product risk analysis failed to identify all important risks from a customer point of view (explanation IV), and the product risk analysis was not updated during the project as new information became available (explanation V). However, there is no information given to suggest that the organization has unrealistic expectations of the percentage of defects that testing can find (explanation II) or that a version-control issue resulted in the release of a version of the software that was used during early testing (explanation III).Rate this question:

What is the most important factor for successful performance of reviews?
- A.
A separate scribe during the logging meeting
- B.
Trained participants and review leaders
- C.
The availability of tools to support the review process
- D.
A reviewed test plan
Correct Answer
B. Trained participants and review leadersExplanation
Trained participants and review leaders are the most important factor for successful performance of reviews. Having individuals who are knowledgeable and experienced in the review process ensures that the reviews are conducted effectively and efficiently. Trained participants are able to provide valuable insights and feedback, while review leaders can guide the process and ensure that all necessary steps are followed. Without trained participants and review leaders, the reviews may lack depth and may not identify all potential issues or improvements.Rate this question:

Consider the following statements about maintenance testing: I. It requires both re-test and regression test and may require additional new tests. II. It is testing to show how easy it will be to maintain the system. III. It is difficult to scope and therefore needs careful risk and impact analysis. IV. It need not be done for emergency bug fixes. Which of the statements are true?
- A.
I and III
- B.
I and IV
- C.
II and III
- D.
II and IV
Correct Answer
A. I and IIIExplanation
Maintenance testing requires both re-test and regression test, as any changes or fixes made to the system may introduce new defects or impact existing functionality. It is also difficult to scope and requires careful risk and impact analysis, as the changes made during maintenance can have unintended consequences. Therefore, statements I and III are true. Statement IV is false because maintenance testing should be done even for emergency bug fixes to ensure that the fix does not introduce new issues or impact other parts of the system. Statement II is not mentioned in the given information, so its truthfulness cannot be determined.Rate this question:

Which two specification-based testing techniques are most closely related to each other?
- A.
Decision tables and state transition testing
- B.
Equivalence partitioning and state transition testing
- C.
Decision tables and boundary value analysis
- D.
Equivalence partitioning and boundary value analysis
Correct Answer
D. Equivalence partitioning and boundary value analysisExplanation
Equivalence partitioning and boundary value analysis are closely related because they both focus on dividing the input domain into smaller, manageable sets. Equivalence partitioning divides the input domain into equivalence classes, where all inputs within the same class are expected to behave the same way. Boundary value analysis, on the other hand, focuses on testing the boundaries between these equivalence classes. By combining these two techniques, testers can ensure that both the representative values within each class and the values at the boundaries are thoroughly tested.Rate this question:

- C.
The others on a project can pressure the independent testers to accelerate testing at the end of the schedule.
- D.
Independent testers sometimes question the assumptions behind requirements, designs and implementations.
Correct Answer
D. Independent testers sometimes question the assumptions behind requirements, designs and implementations.Explanation
Independent testers questioning the assumptions behind requirements, designs, and implementations is an advantage of independent testing because it helps to identify any potential flaws or gaps in the project. This can lead to improved quality and reliability of the software being developed. By challenging assumptions, independent testers provide valuable insights and feedback that can contribute to the overall success of the project.Rate this question:
