Measuring coupling between coverage tasks and use thereof

A computerized apparatus having a processor and a memory device, comprising:

• a coverage task obtainer operative to obtain coverage tasks associated with a Software-Under-Test (SUT), each coverage task is associated with a code element of the SUT;
• a coupling measurements determinator operative to compute coupling measurements of a coverage task with other coverage tasks;
• a coupling score determinator operative to aggregate the coupling measurements of the coverage task to a coupling score of the coverage task;
• and
• a coverage task ranker operative to rank the coverage tasks based on the coupling scores.

A computer program product comprising:

• a non-transitory computer readable medium;
• a first program instruction for obtaining coverage tasks, each coverage task is associated with a code element of a Software-Under-Test (SUT);
• a second program instruction for performing with respect to each coverage task:
• with respect to substantially all other coverage tasks, computing coupling measurements of the coverage task with the other coverage tasks;
• aggregating the coupling measurements of the coverage task to a coupling score of the coverage task;
• a third program instruction for ranking the coverage tasks based on the coupling scores;
• and
• wherein said first, second, and third program instructions are stored on said non-transitory computer readable media.
