RT-Tester (Core)

RT-Tester is a test automation tool for automatic test generation, test execution and real-time test evaluation. Key features include a strong C/C++-based test script language, high performance multi-threading, and hard real-time capability. The tool has been successfully applied in avionics, rail automation, and automotive test projects. More information is available on the product web site here.

RT-Tester Model Based Extension (RTT-MBT)

RT-Tester Model Based Test Case and Test Data Generator (RTT-MBT) supports model-based testing (MBT), that is, automated generation of test cases, test data, and test procedures from UML/SysML models. A number of common modelling tools can be used as front-end for this. The derived test procedures use the RT-Tester Core as a back-end, allowing the system under test to be provided on real hardware, software only, or even just simulation to aid test model development. RTT-MBT includes requirement tracing from test models down to test executions and allows for powerful status reporting in large scale testing projects. More information is available on the product web site here.

FMI/FMU support for RT-Tester / RTT-MBT

The RTT-MBT component is catering for FMI/FMU by a specialised feature release that allows to cast a test procedures to an FMI2-compliant FMU. That FMU is in input to the COE.


In order to operate properly, it is necessary to first obtain the prerequisite tools Python-2.7 and gcc-4.9. An installer collection is available [for Windows] (
