System Testing
During this event, the entire system is tested to verify that all functional, information, structural and quality requirements have been met. A predetermined combination of tests is designed that, when executed successfully, satisfy management that the system meets specifications. System testing verifies the functional quality of the system in addition to all external interfaces, manual procedures, restart and recovery, and human-computer interfaces. It also verifies that interfaces between the application and the open environment work correctly, that JCL functions correctly, and that the application functions appropriately with the Database Management System, Operations environment, and any communications systems.
