Demo that shows how to make use of Event Firing Web Driver.

ClassWithListener

	}

	private void validateWebElement() {
		if (this.element == null)

Hi,

I have my tests automated with Webdriver+Java+TestNG+Maven

I am looking for a solution wherein the progress (Step Into next step) of the test can be controlled using keyboard interrupts on every navigation.

Ex: Lets say we are automation navigation of an application. The progress of the test should be driven by a key press for every page redirection.

I am using the above implementation to achieve this. But hitting on the key is causing an infinite loop & not being detected.

Code -

@Test
public void testMethod(){
    WebDriver driver = new FirefoxDriver();
    EventFiringWebDriver efwd = new EventFiringWebDriver(driver);
    WebDriverListener eventListener = new WebDriverListener(efwd);
    efwd.register(eventListener);
    efwd.get("https://www.myshn.net/shndash");
    efwd.get("https://www.mail.google.com");

  }
}

public class WebDriverListener implements WebDriverEventListener {
private WebDriver webDriver;

public WebDriverListener(WebDriver webDriver){
    this.webDriver = webDriver;
}

public void beforeNavigateTo(String url, WebDriver driver) {

}

public void afterNavigateTo(String url, WebDriver driver) {
    final CountDownLatch latch = new CountDownLatch(1);
    KeyEventDispatcher dispatcher = new KeyEventDispatcher() {
        // Anonymous class invoked from EDT
        public boolean dispatchKeyEvent(KeyEvent e) {
            if (e.getKeyCode() == KeyEvent.VK_SPACE)
                latch.countDown();
            return false;
        }
    };
    KeyboardFocusManager.getCurrentKeyboardFocusManager().addKeyEventDispatcher(dispatcher);
    try {
        latch.await();
    } catch (InterruptedException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }  // current thread waits here until countDown() is called
    KeyboardFocusManager.getCurrentKeyboardFocusManager().removeKeyEventDispatcher(dispatcher);
    System.out.println(this.webDriver.getTitle());
    // TODO Auto-generated method stub

        }
}
