Handling Unexpected Popups@selenium

When ever we have unexpected popup/alert appears in the application,it throws an unhandled alert exception and script will fail. So We have to handle this unhandled alert exception in our test method and then we need to switch to the original content.

Example:
@Test
public void googleTest()
{
try
{
driver.get("http://google.com");
driver.findElementById("q").sendkeys("selenium");
}
catch(UnHandledAlertException e)
{
driver.switchTo().alert().accept();
driver.switchTo().defaultContent();
}
}


The above test method explains about handling unexpected popups.
When ever we have an UnHandlerdAlertException,catch that excption,switch to alert and accept that alert.
Then Switch to Default Content means the original Content.
