To answer this question, you need to understand the concept of loop testing. Loop testing is a control structure testing technique that focuses on testing the validity of loop constructs.

Let's go through each option to understand why it is correct or incorrect:

Option A) Rely basis path testing - This option is incorrect because loop testing is a separate testing technique and is not reliant on basis path testing.

Option B) Exercise the logical conditions in a program module - This option is incorrect because loop testing specifically focuses on testing the validity of loop constructs, rather than exercising logical conditions in a program module.

Option C) Select test paths based on the locations and uses of variables - This option is incorrect because loop testing does not specifically select test paths based on the locations and uses of variables. It primarily focuses on testing the validity of loop constructs.

Option D) Focus on testing the validity of loop constructs - This option is correct because loop testing is a control structure testing technique that specifically focuses on testing the validity of loop constructs.

The correct answer is D. This option is correct because loop testing is designed to specifically test the validity of loop constructs.

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.
