MoveAgent
From Documentation
You can move window and panel by specifying its left and top. As there is no screen rendered when running a test case, no actual window is moved. It just changes target component's left and top attribute.
desktopAgent.query("window").as(MoveAgent.class).moveTo(20,40);
desktopAgent.query("panel").as(MoveAgent.class).moveTo(100,150);
