“…As an alternative, it may be more appropriate to develop techniques based on whether a test is intended to be applied to the simulation code, provide indicators during runtime, facilitate input-output analysis, or conduct exhaustive, formal analysis. Runtime approaches may provide better short-term options for gaining acceptance by the M&S community by providing informal, real-time support for revealing potential errors as they occur [77,158], such as through the use of animations and other visual representations [24,62,72,156] as well as through audial feedback [94]. Emerging runtime approaches help to pinpoint the locations of errors through sound cues [159], spatial plots, and heat maps [128].…”
