Alert handling in Selenium WebDriver (selenium 2) with Java

Solution 1:

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
    }
}

Solution 2:

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();
}

Solution 3:

Alert alert = driver.switchTo().alert();

alert.accept();

You can also decline the alert box:

Alert alert = driver.switchTo().alert();

alert().dismiss();
