Fuzz testing for design assurance levels

Abstract: With safety critical software, it is important that the application is safe and stable. While this software can be quality tested with manual testing, automated testing has the potential to catch errors that manual testing will not. In addition there is also the possibility to save time and cost by automating the testing process. This matters when it comes to avionics components, as much time and cost is spent testing and ensuring the software does not crash or behave faulty. This research paper will focus on exploring the usefulness of automated testing when combining it with fuzz testing. It will also focus on how to fuzzy test applications classified into DAL-classifications.
