This paper reports an automatic method for creating test cases for hardware-in-the-loop (HIL) testing of the body control module (BCM) for automobiles. First, test cases are generated automatically using Unified Modeling Language (UML) modeling software with an automatic test generation add-on. In this work, Rhapsody from IBM with the automatic test generator (ATG) add-on is used to generate automatic test cases. Then, these test cases are converted into Extensible Markup Language (XML) Metadata Interchange (XMI) format. From this XMI format file, test cases for HIL are generated by mapping stimuli such as digital input/output, analog input/output, and controller area network (CAN) interfaces. For this mapping procedure, the pros and cons of Extensible Stylesheet Language Transformations (XSLT) and XML Query Language (XQuery) are discussed.

We report a method to automatically generate test cases for automotive embedded software from a UML-based model using XML metadata interchange (XMI). First, the software model created using UML is converted to metadata in XMI format. Then, based on this metadata (which does not depend on a specific language), software test cases for structural testing or requirement-based testing may be generated using an appropriate parser. The model does not need to be implemented using the Object Constraint Language (OCL), and software test cases may be generated using an appropriately defined parser for a given language (which may be C/C++). Because software test cases can be converted to hardware test cases via a stimulus-mapping table, which contains the information on the digital and analog signals, and the communications interface, hardware test cases may also be generated automatically.
