Rapid runtime system verification using automatic source code instrumentation

This paper describes a tool set for on-line and off-line runtime formal verification of system of systems (SoS) using rapid source-code instrumentation of complex C, C++, and Java applications. The tool set consists of two Eclipse plugins: an automatic source code instrumentation tool and an XML-to-JUnit log-file converter. The automatic instrumentation tool inserts code snippets in the source code of the system under test. During the SUT's execution the code snippets create a log stream (file or socket stream) in XML format. The XML-to-JUnit log-file converter transforms this stream into equivalent JUnit tests within the Eclipse environment. These test scenarios are then executed against state chart-assertion formal specifications, thereby performing runtime verification. The tool set enables runtime verification of formal specifications that contain real-time constraints and is capable of performing such verification for applications running on most popular real-time operating systems.
