We present the test case generation method and tool KeY-TestGen in the context of real-time Java applications and libraries. The generated tests feature strong coverage criteria, like the Modified Condition/Decision Criterion, by construction. This is achieved by basing the test generation on formal verification techniques, namely the KeY system for Java source code verification. Moreover, we present formal specifications for the classes and methods in the real-time Java API. These specifications are used for symbolic execution when generating tests for real-time Java applications, and for oracle construction when generating tests for realtime Java library implementations. The latter application exhibited a mismatch between a commercial library implementation and the official RTSJ documentation. Even if there is a rationale behind this particular inconsistency, it demonstrates the effectiveness of our method on production code.

Abstract. We present a first step towards a framework for defining and manipulating normative documents or contracts described as ContractOriented (C-O) Diagrams. These diagrams provide a visual representation for such texts, giving the possibility to express a signatory's obligations, permissions and prohibitions, with or without timing constraints, as well as the penalties resulting from the non-fulfilment of a contract. This work presents a CNL for verbalising C-O Diagrams, a web-based tool allowing editing in this CNL, and another for visualising and manipulating the diagrams interactively. We then show how these proof-ofconcept tools can be used by applying them to a small example.
