Abstract

Object-oriented programming is used to develop next-generation telecommunications services running on the distributed processing environment. In order to test these services efficiently at the system-level during not only in the development phase but also in the operation phase, we define an embedded monitor service within the infrastructure to monitor the operation of the distributed programs, and describe a system-level test mechanism based on the monitor service. By separating the function of monitor server which monitors operations of objects and collects monitored data and that of tester which makes analysis and decides the sequence of test events, the invasive effect of monitoring can be minimized. At the same time, accurate diagnosis on the system can be achieve by exploiting the test mechanism. The mechanism, as a core component for the implementation of real-time fault-tolerant systems, is applicable to general-purpose distributed systems as well.
