Selenium WebDriver : Handling Javascript Alerts, Confirmations And Prompts

Alerts, Confirmation and Prompts are very commonly used elements of any software webpage and you must know how to handle all these popups In selenium webdriver software automation testing tool. If you know, Selenium IDE has many commands to handle alerts, confirmations and prompt popups like assertAlert, assertConfirmation, storeAlert, verifyAlertPresent, etc.. First of all, Let me show you all three different popup types to remove confusion from your mind and then we will see how to handle them In selenium webdriver.

Alert Popup

Generally alert message popup display on page of software web application with alert text and Ok button as shown In bellow given Image.

Confirmation Popup
Confirmation popup displays on page of software web application with confirmation text, Ok and Cancel button as shown In bellow given Image.

Prompt Popup
Prompts will have prompt text, Input text box, Ok and Cancel buttons.

Selenium webdriver software testing tool has Its own Alert Interface to handle all above different popups. Alert Interface has different methods like accept(), dismiss(), getText(), sendKeys(java.lang.String keysToSend) and we can use all these methods to perform different actions on popups.

Look at the bellow given simple example of handling alerts, confirmations and prompts In selenium webdriver software automation testing tool. Bellow given example will perform different actions (Like click on Ok button, Click on cancel button, retrieve alert text, type text In prompt text box etc..)on all three kind of popups using different methods of Alert Interface.

Run bellow given example In eclipse with testng and observe the result.

package Testng_Pack;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class unexpected_alert {
 WebDriver driver = null;

 @BeforeTest
 public void setup() throws Exception {
  System.setProperty("webdriver.gecko.driver", "D:\\Selenium Files\\geckodriver.exe");
  driver = new FirefoxDriver();
  driver.manage().window().maximize();
  driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
  driver.get("http://only-testing-blog.blogspot.com/2014/01/textbox.html");
 }

 @AfterTest
 public void tearDown() throws Exception {
  driver.quit();
 }

 @Test
 public void Text() throws InterruptedException {
  //Alert Pop up Handling.
  driver.findElement(By.xpath("//input[@value='Show Me Alert']")).click();
  //To locate alert.
  Alert A1 = driver.switchTo().alert();
  //To read the text from alert popup.
  String Alert1 = A1.getText();
  System.out.println(Alert1);
  Thread.sleep(2000);
  //To accept/Click Ok on alert popup.
  A1.accept();
  
  //Confirmation Pop up Handling.
  driver.findElement(By.xpath("//button[@onclick='myFunction()']")).click();
  Alert A2 = driver.switchTo().alert();
  String Alert2 = A2.getText();
  System.out.println(Alert2);
  Thread.sleep(2000);
  //To click On cancel button of confirmation box.
  A2.dismiss();
  
  //Prompt Pop up Handling.
  driver.findElement(By.xpath("//button[contains(.,'Show Me Prompt')]")).click();
  Alert A3 = driver.switchTo().alert();
  String Alert3 = A3.getText();
  System.out.println(Alert3);
  //To type text In text box of prompt pop up.
  A3.sendKeys("This Is John");
  Thread.sleep(2000);
  A3.accept();  
 }
}

This way you can handle different kind of alerts very easily using Alert Interface of selenium webdriver software automation testing tool. Next post will show you how to handle unexpected alerts In selenium webdriver.
