Now it's time for our test script to execute events, such as navigation events. Let's first navigate to Google and then Facebook. We will use the browser back-navigation to go back to Google. The full code of the test script is as follows:

public class IAmTheDriver {
    public static void main(String... args){

        System.setProperty("webdriver.chrome.driver",
                "./src/test/resources/drivers/chromedriver");

        WebDriver driver = new ChromeDriver();

        try {
            EventFiringWebDriver eventFiringDriver = new
                    EventFiringWebDriver(driver);
            IAmTheEventListener eventListener = new IAmTheEventListener();
            eventFiringDriver.register(eventListener);
            eventFiringDriver.get("http://www.google.com");
            eventFiringDriver.get("http://www.facebook.com");
            eventFiringDriver.navigate().back();
        } finally {
            driver.close();
            driver.quit();
        }
    }
}

In the preceding code, we modify our listener class to record navigateTo and navigateBack before and after events inherited from the AbstractWebDriverEventListener class. The modified methods are as follows:

@Override
public void beforeNavigateTo(String url, WebDriver driver) {
    System.out.println("Before Navigate To: " + url
            + " and Current url is: " + driver.getCurrentUrl());
}

@Override
public void afterNavigateTo(String url, WebDriver driver) {
    System.out.println("After Navigate To: " + url
            + " and Current url is: " + driver.getCurrentUrl());
}

@Override
public void beforeNavigateBack(WebDriver driver) {
    System.out.println("Before Navigate Back. Right now I'm at " + driver.getCurrentUrl());
}

@Override
public void afterNavigateBack(WebDriver driver) {
    System.out.println("After Navigate Back. Right now I'm at " + driver.getCurrentUrl());
}

Now if you execute your test script, the output will be as follows:

Before Navigate To: http://www.google.com and Current url is: data:,
 After Navigate To: http://www.google.com and Current url is: https://www.google.com/?gws_rd=ssl
 Before Navigate To: http://www.facebook.com and Current url is: https://www.google.com/?gws_rd=ssl
 After Navigate To: http://www.facebook.com and Current url is: https://www.facebook.com/
 Before Navigate Back. Right now I'm at https://www.facebook.com/
 After Navigate Back. Right now I'm at https://www.google.com/?gws_rd=ssl
