  3. TTCN 3 introduction project SGSN development project Jan.2004 June2004 Introducing TTCN 3 • Why? • The same functional test tool for both GSM & WCDMA access • Automation • New test ports, interfaces and test objects needed • Wanted the advantages in TTCN 3 (speed, debug, usability…) • Re-writing of existing test cases (automation requirements, different structure to support new test objects) • How? • Separate project with GA targeting the start of a SGSN development project • 7 persons – 6 I&V and 1 PLM • Goal: Covering 80 % of the legacy functional req. with automated test cases ~ 1500 test cases
