Schematic Generation of English-prose Semantics for a Risk Analysis Language Based on UML Interactions

Abstract—To support risk-driven testing, we have developed CORAL, a language for risk analysis based on UML interac-tions. In this paper, we present its semantics as a translation of CORAL diagrams into English prose. The CORAL semantics is developed to help software testers to clearly and consistently document, communicate and analyze risks in a risk-driven testing process. We first provide an abstract syntax and a translation algorithm. Then, we evaluate the approach based on some examples. We argue that the resulting English prose is comprehensible by testers, is consistent with the semantics of UML interactions, and has a complexity that is linear to the complexity of CORAL diagrams in terms of size.
