The automated system test procedure ensures the overall functionality for customers. (www.exept.de) Bonnigheim/Stuttgart, 5 August 2009 – Alcatel Lucent tests the Metro core connect with expecco. With the test modeled in expecco and control sequences, a complete hardware test of cross-connect system ordered by the customer is performed automatically. The automated system test procedure ensures the overall functionality for customers. Prior to delivery to the customer, the optical cross-connect of the telecommunications supplier undergoes a strict quality control. The customers can compose individually, the cross-connect as needed. Prior to establishing test with expecco, the individual components (E.g.

assemblies) on special test benches have to be checked manually to your function. The corresponding items were then rebuilt the system ordered by the customer and tested in a defined procedure. This system test was the final acceptance procedure prior to delivery and was the overall functionality desired by the customers safe. Was the task of expecco, this system test carried out using a manual procedure to automate as much as possible. The challenges here were, in particular, that due to the high flexibility in the Assembly and the configuration of the system to be tested usually not ordered system are the same.

Now an optimal mixture of flexibility to achieve maintainability and easy to use, the test system was developed with expecco. The test procedures and configuration sequences were administered in expecco test suites. Through the graphical modeling, these sequences are presented in laymans terms and can be quickly and easily to new versions or even a new hardware of the system under test (SUT) adapt and extend. All of these test suites use in expecco created shared component libraries. Also used partial sequences are integrated in libraries. This hierarchical test architecture system changes can in future when new releases of the SUT Central location to be caught. The interface for the tester was implemented as a wizard. From this wizard the user can launch in expecco modeled test and configuration sequences. During these sequences, each action in the wizard are displayed and logged. Thus, the tester has an overview of the sequence of the currently executing at any time. In the event of a fault, these protocols can be highly detail and use for the diagnosis. As a result, the tester can simply assign errors found in the SUT and fix. Also, arises this by logging the sequences the possibility at a later date to understand and thus serves as a proof that the tests were carried out fully and correctly. The results of the individual sequences are summarized in the wizard to a current test stand and visualized. When all test sequences have successfully run, automatically puts the system into an auslieferbaren initial state, and created a final test protocol. The result is for Alcatel several advantages, such as greater flexibility and maintainability, a user friendly interface for testers and developers, as well as the opportunity of integration system-specific interfaces. Also a very good documentary about the individual test runs and test steps, as well as a custom reporting. The project was developed in an iterative form for two years and adapted to the needs of the customers while. At this time the SUT also further developed, so that the testing and configuration processes had to be adjusted constantly. Often recognized the need to adapt the sequences, only the test of the product itself. It became clear the great advantage of the modeling of the sequences. This extensions and changes in the procedures of settled very quickly.
