Wedding simulation with automated testing allows test organizations to achieve benefits such as increases in testing speed (through-put), increases in test coverage for both hardware and software, and the ability to test before hardware becomes available. In this article, we will describe each type of approach in turn and then how they can work together synergistically.

Simulation generally refers to a model of a process or function; for example, we can simulate the general behavior of a manufacturing process, a motor vehicle, or any other object for which we have knowledge about inputs, outputs, and behavior.

Both simulation and testing have specific goals. For simulation, we want to facilitate requirements generation, uncover unknown design interactions and details, and reduce development cost by having fewer actual parts.

Much of this activity facilitates testing in quantifying the requirements, making testing more productive (Figure 1, below). For testing, we want to achieve defect containment, reduced product warranty cost, and some level of statistical indication of design readiness.
