Handling a confirm box alert

A confirm box is often used to verify or accept something from the user. When a confirm box pops up, the user will have to click either on the OK or the Cancel button to proceed, as shown in the following screenshot:

If the user clicks on the OK button, the box returns true. If the user clicks on the Cancel button, the box returns false.

In this recipe, we will handle a confirm box using the Selenium WebDriver's Alert class.

How to do it...

Let's create a set of tests that handle a confirm box displayed on a page as follows:

1. In the testConfirmAccept test, we will accept the confirm box and verify a message on the page when the confirm box is accepted, that is, when the OK button is clicked as follows:

   @Test
   public void testConfirmAccept()
   {
       //Clicking button will show a Confirmation Alert with OK and Cancel Button
       WebElement button = driver.findElement(By.id("confirm"));
       button.click();
       
       try {
       
           //Get the Alert
           Alert alert = driver...
