Objective

Market openness, technological variety and rising customer expectations are forcing vendors in the field of telecommunications to come to market faster with higher quality products. Bosch Telecom as a developing and manufacturing company in this area is obliged to react to these requirements.
Currently used system test methods, notations and environments are expensive, difficult to use and very time consuming. With the ISO standard 9646 including TTCN (Tree and Tabular Combined Notation) a growing technology has been established to overcome most of these problems.
The main objective of the experiment is to reduce effort and development time by the automation of the test derivation process and by the reuse of formal test case descriptions.

THE EXPERIMENT
The experiment will use TTCN to introduce a formal notation for specifying abstract system test cases which are then automatically transformed into executable programs. These may be used and reused at system test but also during development and maintenance. Thus the experiment consists of two steps.
The first step is the system testing of a product feature with TTCN, by means of the specification, translation and execution of TTCN test suites.
The second step is the integration of a TTCN test system in the development environment, and the use of that system together with the test suites arising from the first step.
The baseline project will be the comparable test tasks of the private communication network division performed with the presently prevailing development and test methods . The software department employs approx. 120 employees, 80 of them involved in the release development of the communication network which includes the baseline project.

EXPECTED IMPACT AND EXPERIENCE
Bosch Telecom expects to gain expertise in using a formal test specification language and an automated test environment to reduce testing effort, thus shortening development by 10 % (e.g. 150 KECU per release) and reducing test effort during customer-specific adaptation or maintenance (e.g. 5 KECU each).
The main expected experience is the winning of developer acceptance for a formal language and the investigation of the possibilities for using TTCN in the integration phase.
