Modelbased testing is an application of modelbased design for designing and optionally also executing artifacts to perform software testing or system testing. The effects of this change on development processes, methods, and tools as well as on required. From its beginnings over 10 years ago of deriving tests from uml statecharts, modelbased testing has matured into a topic with both breadth and depth. Therefore, it is useful and significant to combine the mda approach and uml models with the component technique to develop software for embedded systems 59.
