Private communication networks provide their customers with supplementary services that often have relations or dependencies to old, already-tested services. In the past these services were tested manually on terminal devices. This kind of testing is very time-consuming and ties up a lot of resources, especially if the tests are repeated for new software releases. To overcome these disadvantages, the present system test process of a private communication switch has been modified to reduce the effort involved in executing the system test and to generate more robust system test cases that can survive new software releases. Applying a TTCN-based test method (Tree and Tabular Combined Notation) and building a test tool chain automates a large part of the system test process. This article describes one possibility for automating the system test of a PBX, including a method for specifying functional service tests with TTCN and the test tools used in the test process.
