Managing Concurrency and Parallel Testing with TTCN-3 Telelogic ...

Tips and Guidelines• There is no need to explicitly passed PTC verdicts to the MTCusing coordination messages– A global verdict is automatically maintained by the MTC– The global verdict is updated whenever a component terminates– Remember: Verdict never improve– Make the TTCN-3 script more readable39© Telelogic ABTesting Concept: Self-test of Test Cases• Use Concurrency to perform aself-test of a test case– All behavior is encapsulated in afunction. In the normal case, thisfunction is simply called in theMTC– For Self-Testing, a Simulation ofeach of the SUT Ports isimplemented in one or moreParallel Test Components (PTCs).They are connected to the MTCports– Since the Test System Interfacecan be left empty, SUT Adaptationis not needed for the self-test testsuiteNormalTest systemTest System InterfaceSUTSelftestTest systemPTC (Simu1)PTC (Simu2)Behavior_function()Test System InterfaceMTCBehavior_function()MTC40© Telelogic AB
