I have found such tests come in two forms - the spot
check and the scenario. Because the latter must work
thru the same sequence of clicks as the user will
perform, the tests are long and ugly. 

Refactoring them doesn't make them short or elegant.

I have heard that about Jemmy.

New question:

Suppose this were a Jemmy test case:

  public void testIt ()
  {
    // Turn off Jemmy output.
    
    JemmyProperties.setCurrentOutput
(TestOut.getNullOutput ());
    
    // Shorten timeouts so things fail quicker.
    
    Timeouts.setDefault
("FrameWaiter.WaitFrameTimeout", 5000);
    Timeouts.setDefault
("DialogWaiter.WaitDialogTimeout", 5000);
    Timeouts.setDefault
("ComponentOperator.WaitComponentTimeout", 5000);
    
    // Start the application under test.
    
    HelloWorld.main (new String[0]);
    
    JFrameOperator frame = new JFrameOperator ("Hello,
World!");
    
    // Find 1st (0th) JTextField in frame.
    
    JTextFieldOperator textfield = new
JTextFieldOperator (frame, 0);
    assertTrue ("textfield is enabled",
textfield.isEnabled ());
    assertTrue ("textfield is editable",
textfield.isEditable ());
 ...
}

It paints the screen as it goes.

I don't know enough Swing to answer my favorite
question: How to introduce a temporary line to that
test which blocks the event queue until the user
clicks the close button on the testee window. (Note
the test fixtures might configure the close button to
resume the test, not destroy the window.)
