This chapter introduces validation, verification, and testing tools and techniques pertaining to discrete event simulation. The chapter distinguishes between validation and verification within the context of discrete event simulation. Then, we will show the importance of such topic by revealing the amount research done in simulation validation and verification. The chapter subsequently discusses the reasons why simulation projects fail and the sources of simulation inaccuracies. Next, the chapter gives different taxonomies for validation, verification, and testing techniques (VV&T) for both types of simulation systems: object-oriented-based and algorithmic-based. Therefore, the chapter will present a translation of thirteen software-engineering practices suggested for simulation projects. Notwithstanding the significance of providing an objective assessment platform, as such, the chapter will shed light on the independence of VV&T pertaining to simulation systems.

Aspect-oriented modeling and simulation is a new approach which uses the separation of concerns principle to enhance the quality of models and simulation tools. It adopts the separation of concerns (SOC) principle. Thus, crosscutting concerns such as processes synchronization, steady state detection, and graphical animation could be separated from simulation functional modules. The capture of crosscutting concerns in a modular way is carried out to cope with complexity and to achieve the required engineering quality factors such as robustness, modularity, adaptability, and reusability. This paper provides a summary of aspect-oriented paradigm with its usage in simulation by illustrating the main crosscutting concerns that may infect simulation systems. A practical example is given with the use of the Japrosim discrete event simulation library.
