Alert Handling + Java + webdriver [duplicate]

Answer 1

The idea is when you deal with alerts you have to check whether alert is present first. I would use this approach:

public boolean isAlertPresent() {

  boolean presentFlag = false;

  try {

   // Check the presence of alert
   Alert alert = driver.switchTo().alert();
   // Alert present; set the flag
   presentFlag = true;
   // if present consume the alert
   alert.accept();

  } catch (NoAlertPresentException ex) {
   // Alert not present
   ex.printStackTrace();
  }

  return presentFlag;

 }

here you can get details Also do not forget about debug step by step to get to know on what step alert appears/not appears. Hope this helps you.
