@Test
 public void test () throws InterruptedException
 {
  //Generating Alert Using Javascript Executor
  JavascriptExecutor javascript = (JavascriptExecutor) driver;
  javascript.executeScript("alert('Test Case Execution Is started');");
  Thread.sleep(3000);
  driver.switchTo().alert().accept();
 }
