A Case Study on Testing Activites for KT-OSS Maintenance

This paper describes the testing activities for the maintenance of the KT-OSS (Korea Telecom Operations Support System). Since the KT-OSS is a large software, it is essential to continuously perform maintenance activities such as the addition of new services from business departments and new functions requested by users and operators, performance improvement of existing functions, correction of the errors found during operation of the system, and so on. To ensure the successful maintenance of the KT-OSS without any effect on the existing functions and performance, we performed various tests related to functionality, efficiency and others before the added and modified parts were applied to the KT-OSS. In this paper, we show the maintenance process, the various tests related to it, the test organization, and the test environment for controlling the quality of the KT-OSS maintenance. Through these testing activities, we were able to successfully maintain the KT-OSS.
