Abstract

Model-based testing is a prominent validation technique, integrating well with other formal approaches to verification, such as model checking. Automated test derivation and execution approaches often struggle with asynchrony in communication between the implementation under test (IUT) and tester, a phenomenon present in most networked systems. Earlier attacks on this problem came with different restrictions on the specification model side. This paper presents a new and effective approach to model-based testing under asynchrony. By waiving the need to guess the possible output state of the IUT, we reduce the computational effort of the test generation algorithm while preserving soundness and conceptual completeness of the testing procedures. In addition, no restrictions on the specification model need to be imposed. We define a suitable conformance relation and we report on empirical results obtained from an industrial case study from the domain of electric mobility.
