Window disappears and can not be detected by Selenium.

[Eugene Shragovich]

Hi,

I am running IE 8 and Selenium 2.42.1

Please consider the below scenario:

1. Click on a link on page -> New IE window opens

2. Create a list of current window handles

3. Try to switch to each one of the handles

Problem: The frame does not exists anymore.

So what I wanted to check first is what happens in the time between when the second window appears for the first time and when I actually try to switch to it. For that I created a simple loop that samples all available window handles every 0.01 sec:

for i in range(30):

     print "All sessions:"

     for handle in self.driver.window_handles:

          print handle

  print self.driver.title

  print "========"

time.sleep(0.01)

What I get is the following result:

All sessions:

ad5328c1-28a8-4990-a83e-4cf22e7444d6

394a069b-1f57-4e93-9465-da4ef3f72f7b

========

All sessions:

ad5328c1-28a8-4990-a83e-4cf22e7444d6

========

All sessions:

ad5328c1-28a8-4990-a83e-4cf22e7444d6

========

All sessions:

ad5328c1-28a8-4990-a83e-4cf22e7444d6

. . .

So initially, there are 2 handles/windows appear but you can see that after the first (sometimes it is second or third) sample the second, one of the handles disappear and only one is left.

What's even more interesting, is that when I check the driver title, it shows me the name of the first window but when I interact with the driver, I see that it is actually focused on the newly created window.

This all is super confusing and I hope that I my explanation makes sense. If it does not, please let me know and I will elaborate.

Will be great to hear some ideas as to why such behavior could occur? To me it looks like a bug.

Thanks!

So I tried your scenario with Ruby implementation of Selenium webdriver (using watir, which is a wrapper over selenium webdriver) - Used IE8 and 2.44.0 -- Seems like there is consistent behavior , maybe it is 2.42.1 version that is problematic

Ruby Code (#test.rb)

================

require 'watir-webdriver'
browser = Watir::Browser.new :ie
browser.goto "http://seleniumframework.com/Practiceform/"
browser.button(id: "button1").click
for i in 1..10
  puts "All window handles"
  for handle in browser.windows
    puts handle
    puts handle.title
    puts "==========="
  end
  sleep 0.01
end
browser.quit

Java Code (Paste the code in SimpleTest.java)
package stepDefinitions;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.ie.InternetExplorerDriver;
public class SimpleTest {
    public static void main(String args[]) throws InterruptedException {
        WebDriver driver = new InternetExplorerDriver();
        driver.get("http://seleniumframework.com/Practiceform/");
        driver.findElement(By.id("button1")).click();
        for(int i=0;i<30;i++) {
            System.out.println("All sessions");
            for(String handle:driver.getWindowHandles())
            {
                System.out.println(handle);
                System.out.println("Current handle-"+driver.getWindowHandle());
                System.out.println("=========");
            }
            Thread.sleep(10);
        }
        driver.quit();
    }
}


OBSERVATIONS

In both the cases, I did not notice any confusing behavior as you mentioned (The output files are attached)

1) In Ruby code , the focus was always on parent window handle
2) In Java code , the focus was always on parent window handle
