Connection between Solution Manager Testing und Test Workbench

Hello,

I have Problems understanding the connection between the test organization in the solution manager and the test workbench in the corresponding sap system.

The documentation says that the Solution Manager reuses the test workbench functionality. It is not clear for me how this connection works. In the solution manager you define test cases in the configuration of the project. When you create a test plan in the solution manager you can use the testcases of the project. But when you execute the testcases you do it in the corresponding sap system where the transaction of the test case is. Does this mean that the test cases und test plans that you create in the solution manager are transported to the target sap system? If this is true, when is the transport taking place?

Thanks a lot!

Regards, Lars.
