An approach for detecting inconsistencies between behavioral models of the software architecture and the code

Abstract

In practice, inconsistencies between architectural documentation and the code might arise due to improper implementation of the architecture or the separate, uncontrolled evolution of the code. Several approaches have been proposed to detect inconsistencies between the architecture and the code but these tend to be limited for capturing inconsistencies that might occur at runtime. We present a runtime verification approach for detecting inconsistencies between the dynamic behavior of the documented architecture and the actual runtime behavior of the system. The approach is supported by a set of tools that implement the architecture and the code patterns in Prolog, and automatically generate runtime monitors for detecting inconsistencies. We illustrate the approach and the toolset for a Crisis Management System case study.
