1 Explain Software testing activities should starta. as soon as the code is writtenb. during the design stagec. when the requirements have been formally documentedd. as soon as possible in the development life cycle
2 What is An incident logging systema only records defectsb is of limited valuec is a valuable source of project information during testing if it contains all incidentsd. should be used only by the test team.
3 What is A test design technique isa. a process for selecting test casesb. a process for determining expected outputsc. a way to measure the quality of softwared. a way to measure in a test plan what has to be done

5 Explain Which of the following is true?a. Component testing should be black box, system testing should be white box.b. if u find a lot of bugs in testing, you should not be very confident about the quality of softwarec. the fewer bugs you find,the better your testing wasd. the more tests you run, the more bugs you will find.
6 In which order should tests be run?a. the most important tests firstb. the most difficult tests first(to allow maximum time for fixing)c. the easiest tests first(to give initial confidence)d. the order they are thought of
7 Explain Which of the following is a static test?a. code inspectionb. coverage analysisc. usability assessmentd. installation test

13 Testware(test cases, test dataset)a. needs configuration management just like requirements, design and codeb. should be newly constructed for each new version of the softwarec. is needed only until the software is released into production or used. does not need to be documented and commented, as it does not form part of the releasedsoftware system
14 When reporting faults found to developers, testers should be:a. as polite, constructive and helpful as possibleb. firm about insisting that a bug is not a ?feature? if it should be fixedc. diplomatic, sensitive to the way they may react to criticismd. All of the above

23 Explain The later in the development life cycle a fault is discovered, the more expensive it is to fix. why?a. the documentation is poor, so it takes longer to find out what the software is doing.b. wages are risingc. the fault has been built into more documentation,code,tests, etcd. none of the above
24 Explain which of the following statements is not truea. performance testing can be done during unit testing as well as during the testing of whole systemb. The acceptance test does not necessarily include a regression testc. Verification activities should not involve testers (reviews, inspections etc)d.
