Generate your TTCN test suites

In Telelogic® SDL Suite™, test suite generation is supported by two tools - Autolink and SDL to TTCN Link. These provide an integrated SDL/TTCN environment with access to specifications in SDL directly from the TTCN test case editor. Autolink generates the constraints and dynamic behavior tables of your TTCN test suite. SDL to TTCN Link automatically generates the static parts of the test suite and gives specification-based support for the test case design. The tool also provides a means to check the consistency between an SDL system managed by SDL Suite, and a test specification expressed in TTCN and managed by Telelogic® TTCN Suite™.

Regression testing, a powerful method of checking that old functionality still works when an SDL system has been updated, is also possible in the SDL Suite. You can run MSC test cases and if there are any inconsistencies between your SDL system and the MSCs, the errors are pointed out in the summary presented after the operation.

Regression testing using MSCs allows you to:

• Send signals to the SDL system and check returned signals
• Check if a process instance exists
• Check if process instance x is in state y
• Check process instance variable values
