Monitoring method call sequences using annotations

In this paper we introduce JMSeq, a Java-based tool for the specification and runtime verification via monitoring of sequences of possibly nested method calls. JMSeq provides a simple but expressive way to specify the sequential execution of a Java program using code annotations via user-given sequences of methods calls. Similar to many monitoring-oriented environments, verification in JMSeq is done at run-time, but differently from all other approaches based on aspect-oriented programming, JMSeq does not use code instrumentation, and therefore is suitable for component-based software verification.
