Generalizability of EvoMaster Findings Beyond Volkswagen AG

Ascertain whether the empirical findings about EvoMaster’s applicability, effectiveness, and integration challenges at Volkswagen AG generalize to other industrial contexts, organizations, and REST API fuzzing tools through further studies.

Background

The study reports experience and results obtained in collaboration with Volkswagen AG, noting similarities with open-source APIs but acknowledging limits to external validity.

The authors explicitly state that it is not possible to know for certain whether the results generalize without further studies, identifying a need for broader empirical validation.

References

As such, it seems feasible that our results could generalize in other industrial contexts and tools, although this is not possible to know for certain without further studies.
