Test button mnemonic

[Per Newgro]

Hi *,

maybe someone can turn my light on, how i could test button mnemonic. I tried the following

public class MyPanel extends JPanel {
  public MyPanel() {
    super();
    JButton b = new JButton("Ok with B");
    b.setMnemonic("B");
    add(b);
  }

}

public class MyPanelTest extends JFCTestCase {
  private JFCTestHelper helper = null;
  private JDialog dialog = null;
  private MyPanel testee = null;

  /**
   * Constructor of MyPanelTest.
   */
  public MyPanelTest() {
    super();
  }

  /**
   * @see TestCase#setUp()
   */
  protected void setUp() throws Exception {
    super.setUp();
    helper = new JFCTestHelper();
    testee = new MyPanel();
    dialog = new JDialog();
    dialog.setContentPane(testee);
    dialog.setVisible(true);
  }

  /**
   * @see TestCase#tearDown()
   */
  protected void tearDown() throws Exception {
    super.tearDown();
    dialog.dispose();
    testee = null;
    dialog = null;
    helper = null;
    flushAWT();
    JFCTestHelper.cleanUp(this);
  }

  /**
   * Expect a button action with action id on executing button mnemonic.
   * @param pMnemonic to execute on button throwing event
   * @param pAntiMnemonic to execute on button not throwing event
   * @param pActionId expected to be thrown by button
   * @param pIndex of button in container
   */
  public void testButtonActionByMnemonic() {
    JButton button = get(dialog, JButton.class, 0); // button finden
    assertNotNull("No button found on index 0", button);
    int keyEvent = KeyStroke.getAWTKeyStroke("B",
                                   KeyEvent.ALT_DOWN_MASK).getKeyCode();
    helper.sendKeyAction(new KeyEventData(this, button, keyEvent));
    verify(); // check ob button action <--- no action thrown
  }

}

The test works with enterClickAndLeave, but not with mnemonic sendString.
Maybe someone knows the answer.

Cheers
