WGU C857 Software Quality Assurance - Questions and Answers Already Passed Select the deductive debugging process steps from the lists. Use elimination process Prove remaining hypothesis Enum... erate possible causes Refine remaining hypothesis Collect more data Fix the error -Answer- Enumerate possible causes Use elimination process Refine remaining hypothesis Prove remaining hypothesis Fix the error Collect more data Indicate if the following statements about module testing is true or false. Test cases are supplemented by applying black-box methods to the module's specification. True False -Answer- True Indicate if the following statements about module testing is true or false. Module's logic is analyzed using the white-box methods. True False -Answer- True The only rule in top-down testing is that when selecting the next module for testing, it must be eligible to be the next module, with at least one of the module's subordinate (calling) modules previously tested. True False -Answer- True Which type of tester focuses exclusively on validating the interactions and behaviors that result in functionality? Black-box tester White-box tester Gray-box tester Usability tester -Answer- White-box tester What is the best way to document and keep track of test cases? A set of detailed text files A detailed spreadsheet A bug tracking system A test case management system -Answer- A test case management system Occurs when the number of received parameters are not equal to the number of sent arguments Interface Data reference Computation Data declaration Input/Output -Answer- Interface Requires the user to make changes in the program, which could lead to masking of errors, and so on Automated tools Scatter print statements Storage dump -Answer- Scatter print statements Which test requires the organization that produced the program to create the test cases? Integration test Installation test System test Function test -Answer- Installation test Which statement matches the transaction section of the business layer testing area. Tests to detect errors in knowledge collected from customers Tests to uncover errors in transaction processing, such as credit card processing, e-mailing verification's, and so on Tests whether the application meets documented operational specifications -Answer- Tests to uncover errors in transaction processing, such as credit card processing, e-mailing verification's, and so on Which test case design technique is based on writing test cases around probable types of errors? Identifying equivalence classes Cause-effect graphing Boundary value analysis Error guessing -Answer- Error guessing What is an advantage of incremental testing? Labor costs are smaller Provides opportunities for parallel activities Programming errors are detected earlier It uses less machine time -Answer- Programming errors are detected earlier What must a black-box tester focus on? Knowledge at the source code level How each individual piece of the application works Expected outputs of the program, but not every input What a program is supposed to do and who it is for -Answer- What a program is supposed to do and who it is for Which statement matches the Data validation section of the business layer testing area. Tests to detect errors in knowledge collected from customers Tests to uncover errors in transaction processing, such as credit card processing, e-mailing verifications, and so on Tests whether the application meets documented operational specifications -Answer- Tests to detect errors in knowledge collected from customers ______ is a test case design technique that produces test cases based on intuitive and expert knowledge of test team members for defining potential software errors and facilitating efficient test case design. Cause-effect graphing Logic coverage Error guessing -Answer- Error guessing Select the categories of the completion criteria. Base completion on the use of specific test-case design methodologies Stop after the scheduled time for testing expires. Examine the curve of number of errors found per unit time during the test phase Stop when the test cases are successful State the completion requirements in positive terms -Answer- Base completion on the use of specific test-case design methodologies Examine the curve of number of errors found per unit time during the test phase State the completion requirements in positive terms Which Agile methodology matches this statement: Adapts RUP in which user choose the practices, such as use cases or team programming that fits the project Feature driven development Velocity tracking Essential unified process Dynamic system development method -Answer- Essential unified process Which of the following is a brute-force debugging technique? Process of elimination Studying error symptoms Dumping memory locations Backtracking -Answer- Dumping memory locations [Show More]
