Challenges

Standardized communication protocols and technical specifications do require unique descriptions for testing. At the European Telecommunications Standards Institute (ETSI) most test specifications are defined and standardized using the Testing & Test Control Notation (TTCN-3). This work requires the

• development of very large test suites in parallel team work,
• creation and usage of TTCN-3 libraries, and
• validation with/without the system under test (SUT).
