All Comments have been incorporated. 
1. Replaced ExtendedRobot by Robot
2. focusGainLatch usage fixed with an appropriate countDown
3. Replaced Delay*N with actual values.
4. Removed printStackTrace.
5. UI components access restricted to EDT fixed, both initiatiliseGUI, doTest are now static.
6. @Override added
7. Also the frame.toFront is now removed, as there is already a mouse click on the frame in the code, which is more reliable and has same effect - for the test scenario.
