Dynamic test scheduling by ordering tasks for performance based on similarities between the tasks

According to one embodiment of the present invention, a system dynamically schedules performance of tasks, and comprises a computer system including at least one processor. The system determines resources required or utilized by each task for performance of that task on a target system, and compares the determined resources of the tasks to identify tasks with similar resource requirements. The identified tasks with similar resource requirements are scheduled to be successively performed on the target system. Embodiments of the present invention further include a method and computer program product for dynamically scheduling performance of tasks in substantially the same manner described above.
