Testing distributed systems with test cases dependencies architecture
Résumé
In this work, we present a novel distributed testing architecture based on a formal definition of test cases dependencies to test the conformance of distributed systems in a black box context. Utilizing the European Telecommunication Standards Institute, Test Description Language standard, we apply our approach to a real Internet Multimedia Subsystem (IMS)/ SIP (Session Initiation Protocol) test bed and perform the tests through two use cases. This crucial activity belongs to the conformance testing context. Which aims at stimulating the communication system under test (SUT) to detect errors and unexpected behaviors with regards to the standards. When handling distributed systems, a major difficulty arises when testing these, due to the joint and linked stimulation of distributed entities. The main reason for it is the correlation of verdicts obtained from these entities
