A new role of graphical simulation: Software testing

Simulation is an effective technique to test software where testing in the real environment is not feasible. A 3D graphical simulator can make the software testing process much more effective and efficient. With graphical representation, the software's behavior can be observed in a virtual environment similar to the real environment. This kind of simulator can be best used in testing embedded system software, specifically in systems with many moving objects. Typically, however, the creation of a simulator is expensive in terms of time and cost. In addition, it is difficult to verify the accuracy of the system. We propose an inexpensive 3D graphical simulation method for software testing of embedded systems. This system eliminates the need for mathematical modeling by modeling the physical objects with simple rules. These objects self-coordinate their operation through the application of these rules. The 3D graphical simulator integrates the entire modeling process, eliminating the need for separate simulation and graphical display units. The simulator provides instant graphical feedback of system behavior to illustrate the feasibility and reliability of the system.
