Alert handling in Selenium WebDriver selenium 2 with Java

Question

I want to detect whether an alert is popped up or not  Currently I am using the following code       try           Alert alert   webDriver switchTo   alert                check if alert exists            TODO find better way         alert getText                alert handling         log   info  Alert detected        alert getText             alert accept          catch  Exception e            The problem is that if there is no alert on the current state of the web page  it waits for a specific amount of time until the timeout is reached  then throws an exception and therefore the performance is really bad   Is there a better way  maybe an alert event handler which I can use for dynamically occurring alerts

Write the following method   public boolean isAlertPresent         try           driver switchTo   alert            return true           try     catch  Exception e            return false           catch     Now  you can check whether alert is present or not by using the method written above as below   if  isAlertPresent          driver switchTo   alert        driver switchTo   alert   accept        driver switchTo   defaultContent

You could try   try          if webDriver switchTo   alert      null              Alert alert   webDriver switchTo   alert               alert getText                 etc                 catch Exception e      If that doesn t work  you could try looping through all the window handles and see if the alert exists  I m not sure if the alert opens as a new window using selenium   for String s  webDriver getWindowHandles        see if alert exists here
