QuestionQ18

Selecting the Approach for Test Process Improvement

No defects were found during testing, yet 50 defects were subsequently reported in the production environment after the first release of a new application. It was determined that the relevant component had not been fully tested and that the component-testing process must be improved.

Which ONE of the following tool types would be MOST appropriate to implement to detect the defects earlier?

Explanation

Code coverage tools measure which parts of the application’s code are exercised by tests. They expose untested or insufficiently tested areas of a component, enabling gaps in component testing to be addressed before production release.
