Handle Confirm Alert

How it works

A confirm dialog, from JavaScript's confirm(), asks a yes or no question and returns the answer to the page. In Selenium both answers go through the same Alert: accept() presses OK and dismiss() presses Cancel.

Unlike a simple alert, the choice changes what the page does next. On the Alerts page the answer is written into the confirmResult paragraph, so the test can check that the page reacted to OK or to Cancel, not only that a dialog appeared.

A confirm has no text box. Calling sendKeys() on it throws ElementNotInteractableException with "User dialog does not have a text box input field".

About the assignment

Clicking the confirm button asks whether you want to proceed. You read the question, answer OK, and then read the page's result paragraph to see the answer it recorded.

What you will do

1. 1Click the confirm button, which you locate by its label.
2. 2Switch to the alert, keep its text, and accept it.
3. 3Print the stored question after the label Alert text:.
4. 4Read confirmResult from the page and print its text after the label Result:.

Common mistakes

• Calling dismiss() by habit

  Cancel writes a different result into confirmResult, so the second line no longer matches.

• Reading the result before answering

  The page is blocked while the dialog is open. Finding confirmResult first throws UnhandledAlertException.

• Asserting only the dialog text

  The dialog proves the question was asked. The result paragraph proves the page acted on the answer, which is the part that matters to users.

Starter code

The editor above opens with this code. Fill in the TODO lines, then run and submit it.

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;

public class Main {
    public static void main(String[] args) throws Exception {
        WebDriver driver = new ChromeDriver();
        driver.get("https://testkru.com/Interactions/Alerts");
        
        // TODO: Click "Show Confirm" button
        // TODO: Get alert text, then accept
        // TODO: Print alert text and the result from confirmResult element
        
        driver.quit();
    }
