Formally Defining a Graphical Language for Monitoring and Checking Object Interactions

摘要

Monitoring and checking object interactions is an important activity for testing/debugging scenario implementation in an object-oriented system. In our previous work, we proposed behavior view diagrams (BVD) as a graphical language for writing programs that automate such monitoring and checking process. In this paper, we illustrate the formal definition of the syntax and the semantics of an extended version of BVD that can also be used to describe multi-threaded scenarios. This formal definition provides a critical foundation both for understanding the language and for building its tool support.
