How to handle Random popups in Selenium WebDriver ?

[Sumit Mishra]

Hello,

When running my testscripts, sometimes an popups appears. The problem is that the popup is totally random and I have no way of knowing when it's going to appear.

I need to know what the popups says, so this can be fixed. Can someone tell me how to handle such an popup, so that i can see what the popup says?

Thanks
Sumit Mishra

what kind of popup it is? if it is alert/confirm/prompt, you can override those popup by writing javascript (via web driver) to your UTA page, you can disable those popup and retrieve the content in the popup and writing it to an page element (you may dynamic generate an html element and attach it to the end of html body, the javascript can be injected by web driver).

before run each test step, retrieve the content from this page element, you will get content of it.

window._alert = window.alert;

window.alert = function(str) {

     document.getElementById('popup_content').value=str;

     return false;

}

But something should be aware of, with this javascript, all your alert dialog will not displayed.

I didn't test your case, but above javascript should works.

Best Regards,

if you are testing a site you should probably know the mechanics behind the popup. I would probably talk to your team and see when and why it happens then you will know when you have to check for it or how to avoid it

Hi David,

I am facing similar issue.. Could you please let me know code if it is an alert, something like this: alert("You have a new message");

[Xiang Dong]

Hi,

In general, web driver will not notify your test code there is an alert dialog popup. the only way is try switch to the alert dialog, if no alert present, an exception will throw out. You can try catch the codes and continue check before any other web driver actions.

My codes below is override the basic behavior of native dialog, it will make the alert dialog not display.

Hi Amrita and David,

We can create a while statement which check if alert is present then it will capture alert message and close alert window.

Try below code and let me know if you finding any issue.

http://learn-automation.com/handle-alert-in-selenium-webdriver/

[Xiang Dong]

sure it is a way, but it make the codes complicated, programmer need to check alert present and catch the exception before perform any action, in spite of it, it is not 100% percent works because between the check alert and perform action, there are still some time gap. alert dialog still has possibility to popup. the other way is capture exception for any web driver action, if there is an alert dialog, close it and re-perform the action.

considering it is a random alert dialog, there is no way to anticipate when the alert dialog popup. so, a dedicate logic to handle it is necessary.

Best Regards,

Hi David,

Could you please let me know the "the other way is capture exception for any web driver action, if there is an alert dialog, close it and re-perform the action."

Also, do we have any way to default behaviour of alert() like we have way for window.alert (  ((JavascriptExecutor)driver).executeScript("window.alert = function(msg){};");)

Actually, I had created code for checking alert and take necessary actions. I have placed it at numerous places in the script but each time it executes it takes time. Also, there's no surety that at other places, message will not come.

I am really tired of this one..

Thanks!

Hello,

If it is a java script alert we can create a function to check whether an alert is present or not and call this function before each line of your webdriver script as you doesn't have any information when an alert pops up.

Function to check alert is present or not:

---------------------------------------------------------

public static Alert alert=null;   //declare this a global variable

public boolean isAlertPresent(){

boolean ispresent = false;

                 try{

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

                        ispresent= true;

                     }catch(NoSuchAlertException e){

                         ispresent = false;

                    }

}

Call the above function before each line of your webdriver code and accept the alert. After accepting the alert again assign alert to null;

[Xiang Dong]

your alert dialog is random, you may have three ways to handle it

1. check alert present or not before perform any web driver based action, such as click, but I think you may have a lot of places to add check, it will be a big effort

2. try catch all your web driver action, if there is an unexpected alert present, you will get exception "UnhandledAlertException", catch this exception and accept the alert, then perform your action again.

3. Override windows.alert function, make your web page totally not display it, you need to add this javascript into the web page, web driver can inject it for you. 

Both three ways all have some weakness, the 1 & 2 needs you fix the codes in a lot of places. A fast way for it is that you can implement a new class inherit from WebDriver, WebElement and other web driver classes. add your alert checking code in each web driver actions, includes findElement or methodes. the third one does not requires much codes but it will override alert function, it also includes the intentional alert dialog. 

Hope it can help you.

4. is not make the alert random. if the system is yours nothing should happen randomly, work with your team to find out what causes the popup, then go from there, your tests should be deterministic

if you need tests around the popup, then create a state where the pop up happens consistently. 

if you dont need to test the popup, then create a state where it does not pop up

David,

I had tried the 3rd option but as I mentioned earlier it is not working correctly for alert() function. It works for window.alert() though.

Yes, I had discussed to switch off a functionality that displays alert messages. I have avoided it for now but not sure if I can encounter random pop ups in other areas..

Could you please elaborate on how I can use this especially when I am using a framework for testing.

How to edit a not selenium default alert pop-up in selenium/python? no such alert problem

I have a big problem with the pop-up window, which is clearly not a default alert message in selenium. I've searched everything but there is no solution for the selenium and python problem. I ask for help. I want to edit and click the following popup.

This pop up is not selenium alert

driver.switch_to.alert() does not work. As I said, it is not a selenium alert. This is error wich shown up when i`m using driver.switch_to.alert : selenium.common.exceptions.NoAlertPresentException: Message: no such alert
