            When test runs a Frame which contains a yellow button labeled
            "Drag ME!" and a RED Panel will appear.

            Click on the button and drag to the red panel.
            When the mouse enters the red panel
            during the drag the panel should turn yellow.

            Release the mouse button, panel should turn red again and

            You should be able to repeat this operation multiple times.
