Alert alert=driver.switchTo().alert(); Is not Working with test NG

[MonikaY]

Hi...

In my test class I am using selenium webdriver + testng + page Objects + IE browser
Now there is mandatory field check. on Clicking the "Next" button. a pop up message is shown "Lastname is mandatory." with button "ok". I have made two test classes say "home" and "HomeTest"

HomeTest.java contains
public class HomeTest {
    private WebDriver driver;

   
    @BeforeClass
    public void initWebDriver() {
    driver= new InternetExplorerDriver();
     
    }
   
@Test
    public void testGetErrorMesssage() throws Exception{
        Home home=new Home(driver);
        home.getErrorMessage();
    }


Home.java contains

@FindBy(name="button")
private RenderedWebElement next_button;
    
public Home(WebDriver driver) {
           driver.get("http://application.com");
           PageFactory.initElements(new AjaxElementLocatorFactory(driver, 15), this);
        }

 public void getErrorMessage()throws Exception{
     next_button.click();
     Alert alert=driver.switchTo().alert();
     System.out.println(alert.getText());
     alert.accept();
     }

But my problem is that Eclipse is showing an error line on "alert()" on line "Alert alert=driver.switchTo().alert();" in Home.java
when I mouse over and red line it is showing "The method alert() is undefined for the type WebDriver.TargetLocator"

I don't understand why is this happening :(  ...and this is working fine when I am not using TestNG

Thanks

What version of Selenium are you working with ?

I am seeing a reference to :  RenderedWebElement   which makes me believe that you might be working with an outdated version of Selenium.

Selenium 2 ?? Do you mind stating the actual version of Selenium 2 that you are using ? The latest released version of Selenium is Selenium 2.25.0

try this org.openqa.selenium.Alert instead of Alert

Krishnan asking which version of selenium 2 u r using??

like 2.20....

[MonikaY]

Yes it is "Selenium 2.25.0"

I have used "org.openqa.selenium.Alert alert=driver.switchTo().alert();"
but still getting the error line...........

[Manoj Hans]

can u post complete code of both the class???

[Neeraj Sharma]

Hi Monika, 

 I think try to declare the alert outside the method, may be it can resolve your solution.

[MonikaY]

Manoj.....

I have implemented  as in http://zloiadun.blogspot.in/2010/08/using-page-object-pattern-for-web.html

import org.openqa.selenium.RenderedWebElement;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.FindBy;
import org.openqa.selenium.support.PageFactory;
import org.openqa.selenium.support.pagefactory.AjaxElementLocatorFactory;


public class Home {
    private WebDriver driver;

    @FindBy(name="button")
     private RenderedWebElement next_button;
     
     public Home(WebDriver driver) {
           driver.get("http://application.com");
           PageFactory.initElements(new AjaxElementLocatorFactory(driver, 15), this);
        }

public void getErrorMessage()throws Exception{
     next_button.click();
     Alert alert=driver.switchTo().alert();
     System.out.println(alert.getText());
     alert.accept();
     }

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

Hi Monika, I tried to automate a alert popup window to solve your problem and this code is working fine for me,

public class HomeTest {

private static WebDriver driver;

    

    @Before

   

    public  void initWebDriver() {

    driver= new InternetExplorerDriver();

      

    }

    

@Test

    public void testGetErrorMesssage() throws Exception{

        Home home=new Home(driver);

        home.getErrorMessage(driver);

    }

}

and Home class is as:-

public class Home {

private WebDriver driver;

@FindBy(xpath="//div[3]/p[2]/input")

private WebElement next_button;

    

public Home(WebDriver driver) throws InterruptedException {

          driver.get("http://www.mediacollege.com/internet/javascript/basic/alert.html");

          Thread.sleep(1000);

          PageFactory.initElements(new AjaxElementLocatorFactory(driver, 15), this);

       }

public void getErrorMessage(WebDriver driver)throws Exception{

      next_button.click();

      Alert alert=driver.switchTo().alert();

  System.out.println(alert.getText());

      alert.accept();

}

}

I have just changed the @beforeclass to @Before and passing the driver in the getErrorMessage method as your driver is not passing in your method.

Please have a look into this and let us know if your problem is solved or still facing the same issue.

Thanks,

@Manoj  can we use the @beforeclass for initializing the driver as it runs before the class so i think it may display a error message too.

[Manoj Hans]

@Neeraj...no need to pass webdriver in getErrorMessage method  becoz u already declared Webdriver globally.

[Neeraj Sharma]

Yes,I have tried this but my code is not running after calling the Home class constructor that means the driver is not found by the getErrorMessage method. So I have to pass the driver in it.

[Manoj Hans]

@Neeraj...take both classes as it is which i posted earlier it won't show any error....

[Neeraj Sharma]

Hi Manoj, 

I have tried your code as it is and just modify the URL and the xpath of the button. But what I have found that driver is able to click on the button but after that it display the java null pointer exception for the line Alert alert=driver.switchTo().alert(); and if I pass the driver in the method then it works fine. What is the main reason behind this? Same for my code if i pass the driver in getErrorMessage then it works fine but if I remove it it only runs till clicking on the button but not able to switch to the alert window. 

Neeraj Sharma.

[Manoj Hans]

Ya u r right....need to pass webdriver in the same method

[Neeraj Sharma]

@Monika, have your problem resolved or not?

[MonikaY]

I was making two mistakes:

1) I was using "RenderedWebElement" which is outdated version of Selenium and also including selenium server jar with Selenium 2.25 jar also . Now when I removed "selenium server jar" jar ...the red line under "alert()" is gone .....because of this reason my test case was not running in Firefox and was showing an exception..Now the test case is also running with Mozilla firefox too...Thanks Krishnan :)

2) Secondly, the driver was not found by the getErrorMessage method. So I need to pass webdriver in the same method...Thanks Neeraj and Manoj

[Neeraj Sharma]

@Manoj, I have again checked the code and found that in the Home class constructor we are defining the driver equal to the static driver, so that why we have to pass the driver in the method,

here is the code :-

public Home(WebDriver driver) throws InterruptedException {

this.driver=driver;

          driver.get("http://www.mediacollege.com/internet/javascript/basic/alert.html");

          Thread.sleep(1000);

          PageFactory.initElements(new AjaxElementLocatorFactory(driver, 15), this);

       }

We are not passing the static driver in the constructor so that's why we have to pass the driver in the method:D

[Krishnan Mahadevan]

Monika,

Am glad you figured out what I was hinting at :) Reference to RenderedWebElement in your sample clue was the clue :)
