How to get text from the alert box in java Selenium Webdriver?

In Automation testing, we can capture the text from the alert message in Selenium WebDriver with the help of the Alert interface. By default, the webdriver object has control over the main page, once an alert pop-up gets generated, we have to shift the WebDriver focus from the main page to the alert with the help of switchTO( ).alert( ) method. Once the driver focus is shifted, we can obtain the text of the pop-up with the help of the technique switchTo( ).getText ( ).

Example to get text from the alert box in Java Selenium Webdriver

Take an example of the alert below and its message.

Syntax

Alert al = driver.switchTo().alert();
String st= driver.switchTo().alert().getText();
al.accept();

Here is the code to get text from the alert box in java Selenium Webdriver:

package seleniumpractice;

import java.util.concurrent.TimeUnit;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class AlertMessage {

    public static void main(String[] args) throws Exception
    {

        System.setProperty(
            "webdriver.chrome.driver",
            "F:\\ Maven Selenium\\selenium\\src\\main\\java\\seleniumpractice\\chromedriver.exe"); // Replace the Path in which your Chrome Webdriver stay
        WebDriver driver = new ChromeDriver();
        // implicit wait
        driver.manage().timeouts().implicitlyWait(
            5, TimeUnit.SECONDS);
        // URL launch
        driver.get(
            "https://the-internet.herokuapp.com/javascript_alerts"); // Replace the Site As per need
        Thread.sleep(1000);
        // identify element
        WebElement we = driver.findElement(By.xpath(
            "//*[text()='Click for JS Alert']")); // Location
                                                  // of the
                                                  // AlertBox
        we.click();

        // switch focus to alert
        Thread.sleep(1000);
        Alert al = driver.switchTo().alert();
        // get alert text
        String st = driver.switchTo().alert().getText();
        System.out.println("Alert text is: " + st);
        // accepting alert
        al.accept();
        driver.quit();
    }
}

Explanation

Set Up ChromeDriver:

• System.setProperty() sets the path for ChromeDriver.
• WebDriver driver = new ChromeDriver(); initializes the browser.
• Implicit Wait: driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS); waits for elements for up to 5 seconds.
• Open URL: driver.get("https://the-internet.herokuapp.com/javascript_alerts"); navigates to the page with JS alerts.
• Locate and Click Element: Finds the element triggering the alert using XPath and clicks it.
• Handle JavaScript Alert:
  • driver.switchTo().alert() switches to the alert.
  • getText() retrieves the alert message.
  • accept() clicks the "OK" button on the alert.
• Close Browser:
  • driver.quit() closes the browser and ends the WebDriver session.

The script demonstrates handling JavaScript alerts in Selenium with key actions: launching the browser, clicking an element to trigger the alert, and interacting with it.

Output

Conclusion

Capturing the text from an alert message in Java Selenium WebDriver is a key functionality when automating tests for applications using JavaScript alerts. By accessing the alert using the switchTo().alert() method and retrieving the text with getText(), testers can easily verify the alert content. Implementing this approach ensures more comprehensive test coverage and helps maintain the reliability of web application tests.
