10. Testware(test cases, test dataset)
a. needs configuration management just like requirements, design and code
b. should be newly constructed for each new version of the software
c. is needed only until the software is released into production or use
d. does not need to be documented and commented, as it does not form part of the released
11. An incident logging system
a only records defects
b is of limited value
c is a valuable source of project information during testing if it contains all incidents
d. should be used only by the test team.

a. reducing test time
b. no change
c. increasing test time
d. can’t say
13. Coverage measurement
a. is nothing to do with testing
b. is a partial measure of test thoroughness
c. branch coverage should be mandatory for all software
d. can only be applied at unit or module testing, not at system testing
14. When should you stop testing?
a. when time for testing has run out.
b. when all planned tests have been run
c. when the test completion criteria have been met
d. when no faults have been found by the tests run
15. 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 software
c. the fewer bugs you find,the better your testing was
d. the more tests you run, the more bugs you will find.
