while testing application if you get a scenario of browser back and Forward then how you will handle it in automation script. when I was writing automation script, I am get multiple scenario of browser back and forward in my application testing for that  I am using below code in our script.


Follow below step:
1. Create Driver for any Browser(Mozilla)
2. Go to the URL
3. Navigate to some page in website.
4. Use Selenium code to Navigate Back to Main Page.

public void  browserBack(){

public static void main(String args[]){
WebDriver driver =new FirefoxDriver();
driver.get("http://seleniumhq.org/");
driver.findElement(By.linkText("Download")).click();
Thread.sleep(3000);            //delay in time
driver.navigate().back();
Thread.sleep(3000);            //delay in time
driver.navigate().forward();
        }
}
