问题
Ok, so I'm trying to Unit test some GUI elements I have a JButton with text of "Create" and the mnemonic set on 'C' or code 67. I can write a unit test that I can call the .doClick function on and assert that what that button is supposed to do, happens.
However, I now want to write a unit test to test that the mnemonic portion of that same button works identically to the button click. I've searched on and off for a couple of days now and have tried many things.
I've tried using Robot from the awt library:
robot.keyPress(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_C);
To which no event is being triggered and most recently I've tried this EventQueue example:
final Toolkit toolkit = Toolkit.getDefaultToolkit();
final EventQueue eventQueue = toolkit.getSystemEventQueue();
gPane = new SwingBuilder();
panel = new MainMenuPanel();
panel.displayMainMenu(gPane);
@Test
void ShouldMakeRaceGenderPanelVisibleKeyPress(){
eventQueue.postEvent( new KeyEvent(panel.gPane.mainM, KeyEvent.KEY_PRESSED, System.currentTimeMillis(), 0, KeyEvent.VK_C ).getKeyCode());
assertThat panel.gPane.mainM.isVisible(), is(false);
assertThat panel.gPane.raceGender.isVisible(), is(true);
}
I know that GUI testing can be tricky and there are tools out there to simulate user interaction, but is it really that hard to simulate or trigger just a single KeyEvent?
Any assistance is welcome, and any UI testing tools recommended is welcome as well.
Thanks
Note: This is a combination of Java and Groovy, so I'm using SwingBuilder to build my UI's

You state:

robot.keyPress(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_C);
Perhaps the problem is due to your not taking into account that JButton mnemonics are alt-key combinations, and so your robot code would probably have to reflect this:
robot.keyPress(KeyEvent.VK_ALT);
robot.keyPress(KeyEvent.VK_C);
// possibly want a small Thread.sleep(...) here?
robot.keyRelease(KeyEvent.VK_C);
robot.keyRelease(KeyEvent.VK_ALT);
