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?

This is what worked for me using Explicit Wait from here WebDriver: Advanced Usage

public void checkAlert() {     try {         WebDriverWait wait = new WebDriverWait(driver, 2);         wait.until(ExpectedConditions.alertIsPresent());         Alert alert = driver.switchTo().alert();         alert.accept();     } catch (Exception e) {         //exception handling     } }
