How is statement coverage determined?

Statement coverage is a metric used in software testing that assesses how many of the executable statements in a program have been executed through the testing process. It is calculated by taking the number of statements that have been executed (tested) and dividing it by the total number of executable statements present in the code. This metric helps to identify parts of the code that have not been tested, facilitating more thorough testing efforts.

In contrast, other options relate to different measurement aspects or testing concepts. For example, options related to decision points or outcomes pertain to decision coverage or other forms of code coverage, which focus on evaluating the logical pathways of the code rather than simply counting executed lines of code. Therefore, understanding that statement coverage specifically concentrates on executed statements reinforces why option D is the correct choice for determining statement coverage.
