org.openqa.selenium.NoSuchWindowException: No window found using IE 8 and webdriver 2.0

[JK]

Hi ,

I am getting the following error when using IE 8 and webdriver 2.The same peice of code works fine when used with chrome driver.I am not too sure whats wrong.I also tried adding a sleep before driver.switchTo,window()

the snippet of my code is  :

driver.findElement(By.id("loginbuttons")).click();

   Thread.sleep(5000);

driver.findElement(By.linkText(Apllication)).click();

 

   driver.findElement(By.id("button_logon")).click();

   

   driver.switchTo().window(Window);   

   assertEquals(IBlogonURL, driver.getCurrentUrl());

And the Error is :

org.openqa.selenium.NoSuchWindowException: No window found (WARNING: The server did not provide any stacktrace information)

If it works in Chrome but not in IE it is probably a timing issue. IE is know to be slower than other browsers. Which line opens the new window? if the first click opens the new window then it makes sense to "click, wait 5 seconds, do some thing stuff, switch to the new window". However, if the third click is opening the window, the time between the click and switching to the window has not changed. I would put the 5 second sleep before the driver.switchTo().window(Window) call. If that works then you know you need to wait for the window to appear.

I wrote a blog entry about switching to a popup window. You can find it at http://darrellgrainger.blogspot.com/2012/04/how-to-find-popup-window-if-it-does-not.html.

Essentially, what it does is take the web element for the element which pops open a window. It then:

    get a list of all existing window handles

    click the element based on the provided web element

    get a list of all existing window handles

    subtract all the handles from the first list from the second list

    switch to the new window by handle

This should result in the second list having only one element, the new popup window. In your case the second list will be the same as the first list and fail. You would then do one extra step:

    one = list of all existing window handles

    click the element based on the provided web element

    do {

        two = list of all existing window handles

        sleep for 50ms

    while(one.size() == two.size());

    subtract all the handles from the first list from the second list

    switch to the new window by handle

The loop is the trick. It will sleep for 50ms, check to see if we found the new window, sleep 50ms, check to see if we found the new window.

On Chrome, it will find the window on the first pass, no looping. On IE it will loop just long enough to find the new window (might be 100ms or it might be 5s; doesn't matter).
