Abstract: Modelling and simulation (M&S) is a useful technique for the Department of Homeland Security (DHS) applications because of its non-destructive and non-invasive method of observing a system. Results of simulations are expected to provide reliable information for decision-makers, but potential errors may be introduced during M&S development. This paper identifies the needs of system testing using specifications for M&S applications and provides a novel approach of verification, validation and testing (VV&T) for DHS M&S community. System testing is an effective methodology that can help to ensure the functionality of an M&S applications. Use cases that specify requirements of a simulation system provide information necessary to generate test cases for system testing. System testing allows simulation developers to identify and fix defects much earlier in the lifecycle, which would greatly lower the cost. A case study of a hospital emergency room (ER) simulation model was introduced.
