Handle alerts and prompts

[lukeis]

Originally reported on Google Code with ID 27

Many sites use javascript alerts and prompts to communicate with the user.
It should be possible to test these using WebDriver.

Yes, this will be a great feature!!
Also have a look at watij!!

Yes it would be great!
I'm using WebDriver (r280) to test a website and I am stuck because of a javascript
"confirm" modal window. Is there any known workaround that could help me? I just want
to go through this window by automatically clicking "ok", I actually do not care
about what is displayed. Selenium is able to do that but I prefer WebDriver. Thanks
for your help!

Remark: login-dialog or download-dialog belongs to this sort of prompts too...
        (a workaround with sendKeys(Keys.ESCAPE) doesn't work)

Reported by George.Herczeg on 2008-08-22 06:53:19

[lukeis]

A click on a <a href='...' target='_blank'> opens new windows/tabs...

A click on a <a href='javascript:openpopup();' onclick='return openpopup();'>
   opens new popups

It should be possible to prevent/control opening new windows/tabs/popup.

Possibilities:
 1. override target attribut
 2. callback for controlling new windows/tabs/popup
    (like IE: CHtmlView::OnNewWindow2, CHtmlView::OnBeforeNavigate2
     or CHtmlView::OnShowMessage)
 3. an excellent solution would be the possibility to redirect to my own window, 
    like the IE-code:
    void CMyHtmlView::OnNewWindow2(LPDISPATCH* ppDisp, BOOL* Cancel)
    {
       SetSilent(TRUE);
       *ppDisp = this->m_pBrowserApp;
    }

This bug is to do with handling alerts, prompts and "confirms" from javascript. The
aim is for this to appear as something like:

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

Preventing new windows from being opened is outside the scope of this issue.

Reported by simon.m.stewart on 2008-08-22 09:23:18

The following workaround made it for me:

((JavascriptExecutor) driver).executeScript("window.confirm = function(msg) { return
true; }");

Will this include support for modal dialogs?  I'm referring to the javascript
function showModalDialog (I think IE, FF and safari all support it now)

Do you have plans to implement this soon, because it has become an important issue
for us?  I need to know when an alert has been popped up and dismiss it.  It would
be
nice to read the alert's text too.  I'm starting to think about checking out the
source and having a go myself.  Do you think it's a tough job?

Reported by jjimjam on 2009-02-09 15:32:54

[lukeis]

I'd be delighted if someone else had a go at making this work :) As a short term fix,
you may consider overriding "window.alert" using the JavascriptExecutor.

I started automating a web application using webdriver.During execution of some
testcases i am getting java alerts.When i used
Alert alert = driver.switchTo().alert();
alert.accept();
I am getting error message The method alert() is undefined for the type WebDriver.

would be great if we could handle this without overrriding the window.confirm. After
all this is the point of webdriver, to test this stuff.

Reported by virtix on 2009-04-24 19:53:44

[lukeis]

as a hack you could also inject some javascript to make an html POST or GET when the
js popup is shown. below is just my thoughts, haven't tried it yet

something like:

window.confirm=function(msg){
var winId = window._webdriver_handle_id;
var http = new XMlHttpRequest();
//set location to listening server
//send alert msg, win id
//return true/false
}

The window id is put in the window by webdriver. You'll have to write some  code to
do this. This id allows you to identify what window the alert came from, so you can
check the correct window called it. You then validate the msg. 

You'll also need to open up an http listener in your test code.

We are starting up a testing process with selenium and webdriver.
A solution to this issue would save us a lot of work, because we have a few screens
using alerts/confirmations/modalWindows.

Is there a description of a workaround?

Here's what I use to work around the alert problem with the firefox driver.  I don't
have any other modal windows in my app, but I imagine the solution would be similar
for them.   I'm not that happy with it but it does allow me to detect alerts, check
the text and dismiss them.   

Actually it changes what happens when the js alert function is called, so you won't
see an alert box at all.    Also it won't work like a modal alert and block following
messages.  

registerAlertHack() has to be called just once for each page.   However I don't
really know when the page changes in my app, so I call it the whole time in
'sendMessage'.


  driver = new FirefoxDriver()
  {
    protected String sendMessage(Class<? extends RuntimeException> aClass, Command
command)
    {
      String r = super.sendMessage(aClass, command);
      registerAlertHack();
      return r;
    }
  };



private void registerAlertHack()
{
  if (driver != null)
  {
    String js = "if (window.alert.myAlertText == undefined) {window.alert.myAlertText
= null;  window.alert = function(msg){ window.alert.myAlertText = msg; };}";
    ((JavascriptExecutor)driver).executeScript(js);
  }
}

public boolean jsAlertExists()
{
  return  getJsAlertText() != null;
}

public String getJsAlertText()
{
  Object txt = ((JavascriptExecutor)driver).executeScript("return
window.alert.myAlertText;");
  return (String)txt;
}

public void clickJsAlert()
{
  ((JavascriptExecutor)driver).executeScript("window.alert.myAlertText = null;");
}

I tweaked the workaround that jjimjam submitted to make it a little simpler (for the
JavaScript novice like myself).  In essence you have to know when you will be
generating an alert or confirmation window and you have to know what you want to do
with that window.  So, sometime before the confirmation/alert is generated, just run
this line of code if you want to click OK on a confirm window:
((JavascriptExecutor)m_driver).executeScript("window.confirm = function(msg){return
true;};");

or if you want to click cancel:
((JavascriptExecutor)m_driver).executeScript("window.confirm = function(msg){return
false;};");

or if you want to handle an alert:
((JavascriptExecutor)m_driver).executeScript("window.alert = function(msg){};");

For my situation this seems like a fairly clean situation.  Sure I am overriding the
confirm/alert functions, so they won't handle quite like they would in a real
situation, but I always know before hand what button I want to press on a confirm box
and I really don't care about alert boxes.  Its not a perfect solution, I can't get
the actual message, but its easy and works for me.

Hi team, do you have an estimated resolution or implementation date of this issue?

Reported by edcruz90@hotmail.com on 2010-01-14 16:57:01

I've got a partial fix for the Selenium 1.0.1 version of this bug. With WebDriver and
Selenium merging, I thought I should post it here.

The basic idea is to use the onload event of the iframe containing the AUT to run the
selenium.browserbot._modifyWindow(window) function. 

This fix consists of two changes:
1. Change the RemoteRunner.html file so that this javascript appears in the header:

    function overrideMessageFunctions(iframe) {
        selenium.browserbot._modifyWindow(iframe.contentWindow);
    }

    function addHandler()
    {
        var element = window.document.getElementById('selenium_myiframe');
        var listener = function(){ overrideMessageFunctions(element);};
    if (element.addEventListener)
        element.addEventListener("load", listener, false);
    else
        element.attachEvent("onload", listener);
    }

2. In the AUT, change alert() to:
setTimeout(function(){alert();}, 0); 

This solution works in IE8 for sure, no reason why it shouldn't work for others as
well. Attached is the new RemoteRunner.html file.

+1 for my vote!

As a workaround, this worked for me, though in my case I did not want a return value
as the modal dialog handled everything for the parent. Anyway thought I'd pass it on.

driver.executeScript("window.showModalDialog = window.openWindow;");

Alerts work for java FirefoxDriver 2.3.0, but not for IE 8 nor Chrome on XP. Sorry,
this should be made critical issue as alert messages are basic functionality of any
web page. I had to use workaround with javascript as in comment #78 and it works but
it's not pretty http://code.google.com/p/selenium/issues/detail?id=27#c78
Also, driver.switchTo().alert() should return null, not throw Exception. The problem
is that many times it does not even get to this statment if you have driver.submit()
and javascript validation code that results in alert window and execution hangs on
submit until one clicks on ok button. The work around in #78 works for that scenario,
so before submit alert needs to be disabled and after enabled.

Am I right to think that there is not any way to handle JS alerts invoked in page onload?
Such alerts hang up an WebDriver and tests are stopped.

Any way to handle windows security popups? alert.SendKeys() can send strings to user

not work either, with an exception saying something like "could not find OK button"...

when calling Selenium::WebDriver.get to load a page with an alert, while debuging i
noticed the application hangs until a timeout is reached. Then it just throws an error.
If I can suggest anything, an event callback should be implemented: driver.onAlert
= myAlertHandler, etc. As opposed to injecting some JavaScript wich apparently only
works in some cases. On the other hand calling Selenium::WebDriver.navigate.to instead
went over to the next call in the stack wich game me hope but then when calling driver.switch_to.alert.dismiss
, it hung again untill the thrown timeout error. im using a java remote server and
selenium webdriver 2.5.0. with firefox.

All drivers, to some degree, now support JS alerts and prompts. There are other issues
to do with security dialogs and similar, but those are different from this. Closing

Only after I click the alert manually, the debug control comes to

Hello,
I use Selenium 2.42.0 with Java and I need to use as WebDriver a headless browser like
HtmlUnit or PhantomJS. It`s important that I can handle alert which i trigger on purpose
for testing. I may close the Alert but I need to recognize it somehow in eclipse that
there has been an Alert, like getting the Text of the alert or even an Exception that
there is a alert present. 
 With this javascript i can only close the alert without recognition that there was
an alert:
 if (!(driver instanceof HtmlUnitDriver)) {
            System.out.println("test");
            ((JavascriptExecutor) driver).executeScript("window.alert = function(msg) { 
return true; }");
            ((JavascriptExecutor) driver).executeScript("window.confirm = function(msg) {
return true; }");
            ((JavascriptExecutor) driver).executeScript("window.prompt = function(msg) {
return true; }");
            }


Please is there any possibility just to recognize the alert in eclipse with java and
HtmlUnit or PhantomJs with Selenium!!

The pop up you are dealing with looks like a html type of pop up, thus, it is built
with HTML & javascript. If it is so then you will have to build your own detection
code for it. You should be able to do it rather easily by checking if the pop up element
is present or has certain class.
