Question

I need to activate a JButton ActionListener within a JDialog so I can do some unit testing using JUnit.

Basically I have this:

    public class MyDialog extends JDialog {     public static int APPLY_OPTION= 1;     protected int buttonpressed;     protected JButton okButton;     public MyDialog(Frame f) {         super(f);         okButton.addActionListener(new ActionListener() {             public void actionPerformed(ActionEvent e) {                 buttonpressed= APPLY_OPTION;             }         } );     public int getButtonPressed() {         return buttonpressed;     }  } 

then I have my JUnit file:

public class testMyDialog {      @Test     public void testGetButtonPressed() {         MyDialog fc= new MyDialog(null);         fc.okButton.???????? //how do I activate the ActionListener?         assertEquals(MyDialog.APPLY_OPTION, fc.getButtonPressed());     } } 

This may sound redundant to do in a unit test, but the actual class is a lot more complicated than that…

AbstractButton.doClick

Your tests might run faster if you use the form that takes an argument and give it a shorter delay. The call blocks for the delay.
