"execute" is greyed out under the code menu for the testcase. If I execute the test, then I see some instances, but I don't see instances of any of the test objects. And not sure why. If I execute the top level component for the entire test package, I still don't see instances of the test objects (dummy driver) getting created.
What I am doing is attempting to run a testcase under Test Conductor that I have created against a composite class that wraps the rest of the subsystem that I want to exercise.
So, under TestContexts is a testcase that references a sequence diagram that I created with the Dummy Driver and the SUT (the composite class). Both of these were created automatically when I did a "create Test Architecture" against the composite class in the model. Once the test archicture was created, I created a SD Test, and filled in the SD with a few messages.
However, before any of the messages are sent from the Dummy Driver to the SUT, I get a box popping up with the error message given above. So, still unclear how to get the dummy driver instance to show up.

Thanks for any help!!
