Scenarios to automate:

Launch the application
Verify the internal frame title
Verify the internal frame bounds
Check the frame isMaximizable()
Maximize the frame and check whether it is maximized or not
Demaximize the frame and check whether it is demaximized or not
Check the frame isIconifiable()
Iconify the frame and check whether it is iconified or not
Deiconify the frame and check whether it is deiconified or not
Check the frame isResizable()
Resize the frame and check whether it is resized to new size or not
Move the frame to new location and check whether it is moved to new location or not
Check the frame isClosable()
Close the frame and check whether it is closed or not
Create the frames with different properties (Resizable, Closable, Iconifiable, Maximizable) and corresponding properties (isResizable(), isClosable(), isIconifiable(), isMaximizable())
Resize the main frame, minimize it and check whether it affects the internal frames.
