Using TTCN-3 in Performance Test for Service Application

Abstract

Service applications are applicable to provide services for requests of users from network. Due to the fact that they have to endure a big number of concurrent requests, the performance of service applications running under specific arrival rate of requests should be assessed. To measure the performance of a service application, Multi-party testing context is needed to simulate a number of concurrent requests and collect the responses. TTCN-3 is a test description language; it provides basic language elements for multi-party testing context that can be used in performance tests. This paper proposes a general approach of using TTCN-3 in multi-party performance testing service application. To this aim, a model of service application is presented, and performance testing framework for service applications is discussed. This testing framework is realized for a typical application by developing a reusable TTCN-3 abstract test suite.
