Abstract—The car industry undergoes a big change, triggered by modern agile methods for software development. New software features can be rapidly developed and instantly deployed. In contrast to that stands the long development cycle of the vehicle and its hardware. That hinders the development speed due to hardware related dependencies. Vehicle hardware requires extensive security measurements and procedures. Software embedded directly on the hardware holds many dependencies, varying for different car types within the same manufacturer. In the typical software development an Operating System (OS) diminishes these hardware dependencies and in the means of web development even OS dependencies can be resolved, enabling cross platform development. Therefore the following paper focuses on the development of a test automation architecture. It depicts how our architecture can be built to combine long term vehicle development with rapid agile software development and integrate them together. We call this DeepTesting, the complete test coverage of the software system with its services and applications. Additionally the DeepTesting architecture will consume real world test data to test software under nearly real world condition.
