Title: Measuring coupling between coverage tasks and use thereof

Abstract: Test coverage is enhanced by measuring various types of coupling between coverage tasks. The coupling measurements may be implicit coupling measurements, explicit coupling measurements, coding coupling measurements, performance coupling measurements, resource coupling measurements or the like. Based on the coupling measurements, different coverage tasks may be grouped together. For example, closely coupled coverage tasks may be grouped together. The groups may also be determined based on an initial distribution of groups, by combining groups having closely coupled member coverage tasks. The groups may be ordered and prioritized, such as based on the size of the groups and the number of uncovered tasks in each group. The groups may also be ordered, such as based on coupling score which aggregate the coupling measurements of the member coverage tasks.
