The Internet of Things (IoT) represents a vision in which the Internet extends into the real world embracing everyday objects [9]. Billions of objects are already connected to the Internet. These objects would intercommunicate without any human intervention and they would have different operating systems. Enterprises and developers should produce different versions of each application (same functionality) for each operating systems. For testing and evaluating all these versions, developers and testers should develop/redevelop the same scenario for all versions of this application. Cross-Platform Scenario Module is designed to solve this problem by separating the testing scenario (events and actions) from the application that will execute these events and actions on the object. Same scenario might be written using data serialization formats (such as, Extensible Markup Language (XML), JavaScript Object Notation (JSON) or Concise Binary Object Representation (CBOR)) for all versions of the application. As an example, the format used in this research is the XML.
