Internet of Things (IoT) systems are becoming ubiquitous and assuring their quality is of paramount importance, especially in safety-critical contexts. Unfortunately, few quality assurance proposals are present in the literature. In this paper, we propose an approach for semi-automated model-based generation of executable test cases, oriented to system-level acceptance testing of IoT systems. Our approach is supported by a prototype tool taking in input a UML model of the system under test and some additional artifacts, and produces in output a test suite that checks if the behavior of the system is compliant with such a model. The empirical evaluation of the approach executed on a mobile health IoT system for diabetic patients – involving sensors, actuators, a smartphone, and a remote cloud system – shows that the test suite generated with our tool has been able to kill between 87% and 98% of the mutants (i.e., artificial bugged versions of the system under test).

Abstract

Internet of Things (IoT) systems are becoming ubiquitous and assuring their quality is of paramount importance, especially in safety-critical contexts. Unfortunately, few quality assurance proposals are present in the literature. In this paper, we propose an approach for semi-automated model-based generation of executable test cases, oriented to system-level acceptance testing of IoT systems. Our approach is supported by a prototype tool taking in input a UML model of the system under test and some additional artifacts, and produces in output a test suite that checks if the behavior of the system is compliant with such a model. The empirical evaluation of the approach executed on a mobile health IoT system for diabetic patients – involving sensors, actuators, a smartphone, and a remote cloud system – shows that the test suite generated with our tool has been able to kill between 87% and 98% of the mutants (i.e., artificial bugged versions of the system under test).
