Know how to handle the Alert boxes

Alerts are inevitable in any websites. Mostly they will be prompted to ask confirmations, credentials and dealing them with Selenium is important to learn.

Let's take the example given in this website for doing our exercise.

We are going to see the codes for accepting the alert, cancel the alert and enter text in the alert(prompt box).

Accept / Dismiss the Alert Box.

Send Inputs to the Alert Box

NOTE: Before executing the program, test out the website and check those alerts manually to have a better understanding on how the code works below.

    package seleniumBasics;

    import org.openqa.selenium.Alert;
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.WebElement;
    import org.openqa.selenium.firefox.FirefoxDriver;

    public class HandlingAlerts {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        try {
            System.setProperty("webdriver.gecko.driver", "C:\\Users\\Elcot\\Desktop\\drivers\\gecko\\geckodriver.exe");  
            WebDriver driver = new FirefoxDriver();
            driver.navigate().to("http://www.javascriptkit.com/javatutors/alert2.shtml");

            //The sleep time is added to slow down the execution 
            //so that we can see what's happening
            Thread.sleep(3000);

            //Alert Accept
            WebElement alertBox1=driver.findElement(By.name("B3"));
            alertBox1.click();
            Thread.sleep(2000);
            Alert alert= driver.switchTo().alert();
            alert.accept();
            Thread.sleep(2000);
            // The second accept is because, the example
            // website is showing one more
            alert.accept(); 
            Thread.sleep(2000);

            //Alert Dismiss
            WebElement alertBox2=driver.findElement(By.name("B3"));
            alertBox2.click();
            Thread.sleep(2000);
            alert.dismiss();
            Thread.sleep(2000);
            alert.accept();

            //send input to alert
            WebElement alertBox3=driver.findElement(By.name("B4"));
            alertBox3.click();
            Thread.sleep(2000);
            alert.sendKeys("Agni");
            alert.accept();
            Thread.sleep(2000);
            alert.accept();        
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    }
