The following test is applicable for Single as well
as Multi-monitor screens.
It is a semi-automated test, the test will prompt
the user whether the drag and drop action was successful or not
and automatically PASS/FAIL the test.
If on multi-monitor screens then please position
the drag and drop windows on different screens.
If you can not move the mouse from the frame "Drag Source"
to the frame "Drop Target" press PASS,
else proceed to the next step.
Drag the label "Drag me" and drop it on the
label "Drop on me".
If you can not drag to the second label (for example
if you can not drag across screens) press FAIL.
After the drag and drop action, the test displays
Success/Failure msg in JOptionPane.
Click on OK button and the test is configured to
automatically PASS/FAIL.
