To know with adequate confidence, "when is testing over", which of the following is the best approach?

  1. use test appropriate metrics

  2. declare that it is over when budget is consumed

  3. let the management decide that

  4. declare that it is ove when time is out


Correct Option: A

AI Explanation

To answer this question, you need to understand the concept of test completion criteria. Test completion criteria are predefined conditions or metrics that are used to determine when testing is considered to be complete. Let's go through each option to understand why it is correct or incorrect:

Option A) Use test appropriate metrics - This option is correct because using test appropriate metrics is the best approach to determine when testing is over. These metrics can include factors such as test coverage, defect detection rate, and test pass rate. By measuring these metrics against predefined thresholds, you can assess the adequacy of testing and determine when it is complete.

Option B) Declare that it is over when the budget is consumed - This option is incorrect because the budget consumed may not necessarily indicate the completion of testing. Testing may be incomplete even if the budget is fully consumed, especially if the test objectives and criteria are not met.

Option C) Let the management decide that - This option is incorrect because relying solely on management to determine when testing is over may not be the most objective or accurate approach. Management decisions may be influenced by factors other than the actual testing progress and quality.

Option D) Declare that it is over when time is out - This option is incorrect because simply declaring testing to be over based on the expiration of a predetermined time limit may not take into account the actual completion of testing objectives or the achievement of desired quality levels.

The correct answer is Option A) Use test appropriate metrics. This option is correct because it allows for a more objective and quantitative assessment of testing progress and quality, based on predefined criteria or metrics.
