Alert Handling in Selenium

For practice use the below alert buttons and validate the proper message.

Handling alerts in Selenium WebDriver involves dealing with pop-up dialogs that appear during automated testing, such as alert, confirmation, and prompt dialogs. These dialogs can interrupt the test execution flow and require specific actions to handle them appropriately. Here's a brief introduction to handling alerts in Selenium WebDriver with a code hint in Java:

Code copied to clipboard!

// Import necessary Selenium WebDriver classes
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;

public class AlertHandlingExample {
    public static void main(String[] args) {
        // Set the path to the ChromeDriver executable
        System.setProperty("webdriver.chrome.driver", "path_to_chromedriver");

        // Instantiate ChromeDriver
        WebDriver driver = new ChromeDriver();

        // Navigate to a webpage containing an alert
        driver.get("https://www.example.com");

        // Find the element that triggers the alert (e.g., a button)
        driver.findElement(By.id("alertButton")).click();

        // Switch to the alert
        Alert alert = driver.switchTo().alert();

        // Get the text of the alert
        String alertText = alert.getText();
        System.out.println("Alert Text: " + alertText);

        // Perform an action on the alert (e.g., accept/dismiss)
        alert.accept(); // To accept the alert
        // alert.dismiss(); // To dismiss the alert

        // Close the browser
        driver.quit();
    }
}

Explanation:

The import statement imports the necessary Selenium WebDriver classes.
The System.setProperty() method sets the path to the ChromeDriver executable.
The WebDriver interface is the root interface for all Selenium WebDriver classes.
The ChromeDriver class is a concrete implementation of the WebDriver interface, and is used to control Chrome browsers.
The driver.get() method navigates to a webpage containing an alert.
The driver.findElement(By.id("alertButton")) method finds the element that triggers the alert (e.g., a button).
The driver.findElement(By.id("alertButton")).click() method clicks on the element that triggers the alert.
The driver.switchTo().alert() method switches to the alert.
The alert.getText() method gets the text of the alert.
The System.out.println() method prints the text of the alert to the console.
The alert.accept() method accepts the alert.
The driver.quit() method closes the browser.

The key points are:

The import statement imports the necessary Selenium WebDriver classes.
The System.setProperty() method sets the path to the ChromeDriver executable.
The WebDriver interface is the root interface for all Selenium WebDriver classes.
The ChromeDriver class is a concrete implementation of the WebDriver interface, and is used to control Chrome browsers.
