Go4IT is a test environment based on the TTCN-3 language. This standardized language simplifies the process of translating an existing standard into test cases and test suites. Using a TTCN test environment allows you to validate hardware or applications against a given standard. A user management interface together with logging capabilities allow you to fine tune the tests to be run and exploit the results to solve the issue in case a test would fail.
