Hi,
I don't completely understand, why you want to reset the UUTLoopIndex, because it shows the number of iterations per test socket to check how many uut's have been tested on each. However, you could reset the value with a simple statement before you start the tests. You could do this in the setup step group, e.g. with RunState.Root.Parameters.TestSocket.UUT.UUTLoopIndex = 0. You could add a message popup or evaluate an extra condition or so.
