Determine ECU test cases with ease in version 2.1 of Vector’s vTESTstudio

LinkedIn +

Version 2.1 of vTESTstudio from Vector offers support in determining the right test cases in vehicle ECU analysis with its new graphical editor for the classification tree method. This method helps both OEMs and suppliers to reduce the number of test cases to only those that are relevant.

The input data range is often so large that complete test coverage of all values is unrealistic in practice. Therefore the value range of each classification is sub-divided into so-called equivalence classes, for example vehicle speed <50km/h.

“The idea behind forming equivalence classes is that the same behavior of the SUT is expected for all values within a class,” explained Ute Katranski, product manager for vTESTstudio.

“Thus it is completely sufficient to consider exactly one representative from each equivalence class, which markedly reduces the number of test cases, allowing significantly more efficient utilization of the test resources.”
