ATheNA-S: A Testing Tool for Simulink Models Driven by Software Requirements and Domain Expertise

Search-based software testing (SBST) is widely used to verify software systems. SBST iteratively generates new test inputs driven by fitness functions, i.e., objective functions that guide the test case generation. In previous work, we proposed ATheNA, a novel SBST framework that combines fitness functions automatically generated from requirements' specifications with those manually defined by engineers, and showed its effectiveness. This tool demonstration paper describes ATheNA-S, an instance of ATheNA that targets Simulink models. We demonstrate our tool using an automotive case study and present our implementation and design decisions. A video walkthrough of the case study is available on YouTube: youtu.be/dhw9rwO7L4k.
