Which TWO of the following metrics would be MOST suitable for determining whether the test objective has been met?

Test objectives for systems testing of a safety critical system include completion of all outstanding defect correction. Regression testing is required following defect correction at all test levels.

Answer: A

Explanation:

Test objectives are specific goals or targets that define what testing activities should achieve or accomplish1. Test objectives for systems testing of a safety critical system include completion of all outstanding defect correction. Regression testing is required following defect correction at all test levels.

Therefore, to determine whether this test objective has been met, two metrics that would be most suitable are:

Regression tests run and passed in systems testing: This metric measures how many regression tests have been executed and passed in systems testing1. Regression testing is a type of testing that verifies that previously tested software still performs correctly after changes or defect corrections1. This metric can indicate whether all outstanding defect corrections have been completed and verified in systems testing.

Incidents raised and closed at all levels of testing: This metric measures how many incidents have been reported and resolved at all levels of testing1. An incident is any event occurring during testing that requires investigation1. This metric can indicate whether all defects have been identified and corrected at all levels of testing.
