Combining testing and runtime verification

Abstract

Testing and runtime verification are intimately related: runtime verification enables testing of systems beyond their deployment by monitoring them under normal use while testing is not only concerned with monitoring the behaviour of systems but also generat- ing test cases which are able sufficiently cover their behaviour. Given this link between testing and runtime verification, one is surprised to find that in the literature the two have not been well studied in each other’s context. Below we outline three ways in which this can be done: one where testing can be used to support runtime verification, another where the two techniques can be used together in a single tool, and a third approach where runtime verification can be used to support testing.
