To answer this question, you need to understand the concept of testing completion criteria.
Option A) When the budget is consumed - This option is incorrect because testing completion should not be solely based on budget consumption. While budget can be a factor to consider, it should not be the sole determining factor for when testing is over.
Option B) Use test appropriate metrics - This option is correct because using test appropriate metrics is the best approach to determine when testing is over. Test metrics can include factors such as test coverage, defect density, and test pass rate. These metrics provide objective data to evaluate the progress and effectiveness of testing, and can help determine when the testing objectives have been met.
Option C) When the time is out - This option is incorrect because testing completion should not be solely based on the passing of a specific time duration. While time can be a factor to consider, it should not be the sole determining factor for when testing is over.
Option D) Let the management decide - This option is incorrect because while management input and decision-making can be valuable, it should not be the sole determining factor for when testing is over. Testing completion should be based on objective criteria and metrics.
The correct answer is B) Use test appropriate metrics. This option is correct because using test appropriate metrics provides objective data to evaluate the progress and effectiveness of testing, and helps determine when the testing objectives have been met.
