Q. 718: Which of the following are benefits and which are risks of using tools to support testing? Show 1. Over-reliance on the tool A. Benefits: 3, 4, 6
and 7. Risks: 1, 2 and 5 Q. 721: Consider the following list of test process activities: I. Analysis and design Which of the following places these in their logical sequence? A. I, II, III, IV and V. Q. 734: Assume postal rates for 'light letters' are: $0.25 up to 10 grams; Which test inputs (in grams) would be selected using boundary value analysis? A. 0, 9,19, 49, 50, 74, 75, 99,100 Q. 742: 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. Q. 753: Which of the following best describes typical test exit criteria? A. Reliability measures, number of tests written, and product completeness. B. Thoroughness measures, reliability measures, cost, schedule, tester availability and residual risks. C. Thoroughness measures, reliability measures, test cost, amount of time spent testing and product completeness, number of defects. D. Time to market, residual defects, tester qualification, degree of tester independence, thoroughness measures and test cost. Q. 778: Which ordering of the list below gives increasing levels of test independence? a. Tests designed by a fellow-member of the design team. b. Tests designed by a different group within the organization. c. Tests designed by the code author. d. Tests designed by different organization. A. c, a, b, d. B. d, b, a, c C. c, a, d, b. D. a, c, d, b. Q. 782: The following table shows 6 test procedures (P to U) that must now be entered into a test execution schedule. Test Proce-dure ID Business Priority Dependencies on test procedures Other dependencies P 1 Can not start unless R has completed Q 1 None Regression testing only R 2 None None S 2 None None T 3 None Delivery of the code for this part of system is running very late U 3 None None Business severity is regarded as the most important element in determining the sequence of the test procedures, but other dependencies must also be taken into consideration. Regression testing can only be run once all other tests have completed. Which of the following represents the MOST effective sequence for the test execution schedule (where the first entry in the sequence is the first procedure to be run, the second entry is the second to be run and so on)? A. Q, P, S, R, U, T. B. R, S, U, P, Q, T. C. R, P, S, U, T, Q. D. P, Q, R, S, U, T Q. 785: The flow graph below shows the logic of a program for which 100% statement coverage and 100% decision coverage is required on exit from component testing. Picture The following test cases have been run: Test Case 1 covering path A, B, D, G Test Case 2 covering path A, B, D, E, F, E, F, E, F, E, G Test Case 3 covering path A, C, D, E, F, E, G Which of the following statements related to coverage is correct? A. Statement coverage is 100%; decision coverage is 100%. B. Statement coverage is less than 100%; decision coverage is 100%. C. Statement coverage is 100%; decision coverage is less than 100%. D. Statement coverage and decision coverage are both less than 100%. Why are experience based test techniques good to use?Experience-based techniques come in handy in such situations. They use the tester's experience to understand the most important areas of a system i.e. areas most used by the customer and areas that are most likely to fail. They tap into the tester's experience of defects found in the past when testing similar systems.
What is experience based test design technique?Experience-based techniques are based on the tester's experience with testing, development, similar applications, the same application in previous releases, and the domain itself. The tester brings all their knowledge to bear when designing the test cases.
How do experience based techniques differ from specification based techniques?How do experience-based techniques differ from specification-based techniques? They depend on the tester's understanding of the way the system is structured rather than on a documented record of what the system should do. They depend on having older testers rather than younger testers.
Which of the following provides the best description of exploratory testing?Which of the following provides the BEST description of exploratory testing? A testing practice in which an in-depth investigation of the background of the test object is used to identify potential weaknesses that are examined by test cases.
