This Exception occurs when driver is trying to perform action on the element which is no longer exists or not valid.
In order overcome this, we need to explicitly wait until the DOM is in a state where we are sure that DOM won't change. Here the reference to the element in the DOM that previously had becomes stale and we can no longer able to use this reference click call to interact with the element in the DOM.
Try to get around this by first using an explicit wait on the element to ensure the ajax call is complete, then get a reference to the element again. You can also user implicit waits, in which Webdriver will check for the element to become present until the specified timeout:.
If even this is not working for you, try giving an other locator which gives some positive results.

This solution is not recommended because of time taken for each iteration that fails to find the element and end up wasting time in retry.

It depends on browser. Your name. More information about text formats. Save Preview. All Rights Reserved.The Stale Element Reference Exception is one of the infamous exceptions in selenium. This exception is caused when:.
Every HTML webpage contains elements buttons, links, checkbox etc. In this example, we will try to perform some operation on a web element.
Once the action is performed, we will refresh the browser through the code and try to perform same operation on the same web element. A pop up is displayed with some text and Close button.
Click on the Close button and then hit refresh to again see the pop up. This refresh operation triggers DOM restructuring and our test will fail if it tries to click on Close button again. This failure happens due to Stale Element Reference Exception as the reference of Close button is obsolete after the page refresh.
Below code tries to emulate the Stale Element Reference Exception:. Below is break down of the code:.

I'm implementing a lot of Selenium tests using Java. Sometimes, my tests fail due to a StaleElementReferenceException. Could you suggest some approaches to making the tests more stable? This can happen if a DOM operation happening on the page is temporarily causing the element to be inaccessible. To allow for those cases, you can try to access the element several times in a loop before finally throwing an exception. Try this excellent solution from darrelgrainger. I was having this issue intermittently.
Get around this by first using an explicit wait on the element to ensure the update is complete, then grab a fresh reference to the element again. But anyway, best solution is to rely on Selenide library, it handles this kind of things and more. The reason why the StaleElementReferenceException occurs has been laid out already: updates to the DOM between finding and doing something with the element. This actually waits and checks if the element in question has been refreshed during the specified timeout and additionally waits for the element to become clickable.
Have a look at the documentation for the refreshed method. In my project I introduced a notion of StableWebElement. It is a wrapper for WebElement which is able to detect if element is Stale and find a new reference to the original element. I have added a helper methods to locating elements which return StableWebElement instead of WebElement and the problem with StaleElementReference disappeared. Kenny's solution is deprecated use this, i'm using actions class to double click but you can do anything.
There could be a potential problem that leads to the StaleElementReferenceException that no one mentioned so far in regard to actions.Everything worked like clockwork. We had vouchers for everything all neatly organized in our arrival package. Can somebody give Helga G. We loved the notes that she put on the map for us about places we never would have discovered on our own.
We were so happy with our experience that we made sure to go to the Nordic Visitor office on our last day to say thank you in person to Helga. Iceland was spectacularly beautiful.
We have also always wanted to see the Northern Lights, and I would not hesitate at all to contact Nordic Visitor in the future to arrange that trip for us. Just got back from a 7 day tour of southern Iceland organized by NordicVisitor.
I was impressed that I went into this trip with no real knowledge of what I was getting myself, my wife and three teenage children into. The trip went on without a single hitch. The car rental, hotel reservations and activities were all perfect and we had a blast. Thank you and I would recommend this company to anyone. The only hitch was cost which was difficult to get a handle on.
In particular, the activities were costly. BUT, well worth every penny. We joined the Nordic Visitor tour party on the 25rd July following two days in Reykjavik on our own.
Nordic Visitor arranged for a taxi (with welcome pack and documents) to pick us up from the airport on Thursday and on to our pre tour accommodation, we then made our way to the tour hotel on the Saturday evening. Our guide Porsteinn (Steine) met us at the welcome meeting and told us our agenda. Sunday morning the tour set off at 9am the starting time for everyday. The tour went round the whole island (around 2000km covered) visiting all the major sites that can be reached from the N1 ring road.
We were of the 'comfort' level of accommodation and all the hotels and guesthouses were of at least 3 star quality with large clean rooms and en-suite facilities. Some had fabulous views as well. The guide constantly fed us information of the sites we visited in an informal but informative way with a construction fonts dafont Icelandic folk stories and jokes thrown in. The transport was a mini bus taking 16 of us comfortably from site to site with various comfort stops on the way.
There is a little walking to be done for example up to Dettifoss that cannot be avoided but all the walks were really strolls and nothing over taxing. The evening meals that were provided as part of the package were either in the accommodation or at local restaurants and were of a very high quality. There are optional extra's such as Whale Watching and the Thermal baths which although we pre booked could be booked on the tour. Transfer back to the airport was provided.
In summary this was a very well organised tour both before leaving home and whilst there. The program is varied and interesting, capturing all the major attractions. Would highly recommend the tour to anyone wanting to see the main sites but not do all the legwork of a self drive.
A friend and I (who live in Australia and UK respectively) were keen to do a self drive tour of Iceland as we could have autonomy and flexibility and avoid the tour bus hordes. We found Nordic Visitor through Google and I'm so glad we did.
We chose the 10 day Full Circle tour - which comes with a rental car, pre booked accommodation, detailed road map, local mobile phone, GPS and many suggestions for destinations and activities. We opted for a 4x4 vehicle (highly recommended as there is a fair amount of off-roading) and budget accommodation which was pretty much guesthouses. That's part of the deal anywhere really.
There is so much to say about the trip itself so feel free to send a message if you want more info. Nearly all the arrangements went without a hitch and what didn't go smoothly wasn't due to Nordic Visitor getting it wrong and indeed didn't ruin the trip at all (eg the guesthouse in Reykjavik wasn't aware of my travelling companion's very early arrival and were not prepared).
My only negative comment is some of the worthwhile sights might not be on their recommended itinerary so do a little research of your own.This question is in the form of a paragraph which How to Do True False Not Given Type of Questions in IELTS Reading.
