TTCN (Testing and Test Control Notation) is a standardized testing language used for specifying and executing test cases for protocol and service testing. It provides a framework for defining test behaviors, test data, and the communication between the system under test and the tester, facilitating automated testing of complex systems.

About Ttcn
TTCN was developed in the late 1980s by the European Telecommunications Standards Institute (ETSI) to address the need for a standardized testing language for telecommunications protocols. It evolved over time to support a broader range of applications beyond telecommunications, becoming a key tool for automated testing in various industries.
Strengths of TTCN include its standardization, flexibility in defining complex test scenarios, and strong support for automated testing. Weaknesses involve its steep learning curve and complexity in setup. Competitors include JUnit for Java applications, NUnit for .NET applications, and other domain-specific testing frameworks like Robot Framework.
