Câu 4: Your team has concluded testing and is preparing the test summary results for review with the

stakeholders at a management review. You will provide quantitative metrics to stakeholders in order to obtain

a collective decision regarding the readiness for release.

should continue?

• B. W, X and Y

• C. W and X

• D. W, X and Z

Câu 7: Consider the typical objectives of testing. Which of the following metrics can be used to measure the

effectiveness of the testing process in achieving one of those objectives?

• A. Average number of days between defect discovery and resolution

• B. Percentage of requirements covered

• C. Lines of code written per developer per day

• D. Percentage of test effort spent on regression testing

Câu 8: Considerable attention will be given in this project to defining exit criteria and on reporting back on

their status. Which combination of TWO exit criteria from the list would be best to use?

I. Total number of defects found

Il. Percentage of test cases executed

IlI. Total test effort planned versus total actual test effort spent

IV. Defect trend (number of defects found per test run over time)

• A. (I) and (II)

• B. (I) and (IV)

• C. (II) and (III)

• D. (II) and (IV)

Câu 9: Which one of the following statements about testing metrics usage is TRUE?

• A. Trends in the lag time from defect reporting to resolution are used to reward the developers

• B. Confirmation and regression test status is used to monitor the progress of testing

• C. Planned versus actual hours to develop testware is used to minimize regression testing

• D. Number of test conditions identified is used to monitor the quality of testing

Câu 10: You work for an international company producing hardware and software for telecom networks

Hardware and software development are done in separate business units. You are the test manager of one

product line of network router software.

In your product line there is a long tradition of creating tightly integrated products using an incremental product

lifecycle. The hardware business unit produces a new version every six months. Your software product line

aims to have a new version of the software ready for each new hardware version. The software is developed in

two-month increments.

The business unit schedules are synchronized during design.

Your team consists of 15 testers, who have been in the company for two years, but mostly a lot longer. New

tests are developed by the most experienced test analysts as in-house custom test scripts. Variations of tests and

the regression test sets are run by the rest of the team.

The company management requires monthly progress reports listing the number of severe defects found and the

status of test execution. There have also been efforts to measure the efficiency of personnel in all business units

Your company has also implemented CMMI on company level.

There have been problems to keep up with the hardware development schedule. Your manager thinks that the

project might find some defects more efficiently by having testers review the business requirements.

Which three of the following metrics would be used best to prove this point during review trial?

• A. Dynamic test coverage

• B. Review and dynamic testing hours

• C. Test execution status

• D. Number of defects found in dynamic testing

• E. Number of defects found in reviews

  F. Review results of hardware and software business units

  G. Number of severe defects in dynamic testing
