Aborting on channel error & Unable to kill process

[Candide7]

Firefox Version: 51.0.1 (updated the 24th of February, 2017)

Platform: Win10 64

Steps to reproduce -

Hello, I updated this morning all my libraries:

• Firefox 51.0.1
• Selenium-server-standalone 3.1.0
• Gecko 0.14

Now I run the same test as before and it seems to end correctly except in the traces:

GRAVE: Unable to kill process with PID 9412

Basically this is what I run:

System.setProperty("webdriver.gecko.driver", "Regulus_lib/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("http://www.google.com");
try {
   driver.quit();
} catch(org.openqa.selenium.remote.UnreachableBrowserException e) {
/* Since Selenium 3 and the use of Gecko, driver.quit() causes exception each time
 * Indeed gecko let a channel thread opened with the selenium webdriver.
 * To test again with future stable version.
 * Update: Gecko 0.14 seems to fix this problem. */
driver = null;
}

The problem seems to be related to the driver.quit(). Note that the Firefox Window closes correctly at the end. I tried to figure it out using driver.close() also but nothing good with it.

Am I doing womething wrong please?

Thanks for your help.

I have a work-around for this issue when running your test on selenium grid using firefox. Or when running it localy on your machine. I created a bat file that automatically kills the process after 5 min

You can also send a commando to kill your proces tskill WerFault after browser driver.quit();

@echo off cls :start echo This is a loop tskill WerFault TIMEOUT /T 300 goto start

Hello thasherwin and thanks for the response. Yes of course I could manually stop it but well it is not exactly a pretty solution. Especially in my case since my soft will be used by a third person.

[thasherwin]

Yes correct.. It's just a work-around untill Gecko team looks into this issue and solve it

Adding my finding to this issue.

Browser : Firefox Nightly 54.0, Firefox 51.0 Selenium : 3.1.0 GeckoDriver : geckodriver-v0.14.0-win64

GeckoDriver is happy with most of the websites but it is crashing for some main websites.

Website Crashing

http://www.cnn.com/ http://www.dailymail.co.uk/ https://www.bet365.com/ http://www.foxnews.com/ http://abcnews.go.com/

Most of the other site I have checked worked without any problem

When driver.quit() is called it will show the message "Plugin container for Nightly stopped working"

Here is the message displayed in Firefox popup (For all the above websites its the same)

I am sharing the code I have used. This issue is consistent for any of the above websites.

Code

package CrossBrowser.Tests.POC;

import java.net.URL;

import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.firefox.FirefoxProfile; import org.openqa.selenium.remote.DesiredCapabilities; import org.openqa.selenium.remote.RemoteWebDriver; import org.testng.annotations.Test;

public class GeckoDriverIssue {

WebDriver driver;

@Test(description = "Launch Website")
public void geckoDriverIssue() {        

    try {
        FirefoxProfile fp = new FirefoxProfile();
        DesiredCapabilities firefoxCapabilities = DesiredCapabilities.firefox();
        firefoxCapabilities.setCapability(FirefoxDriver.PROFILE, fp);
        firefoxCapabilities.setCapability("marionette", true);
        driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), firefoxCapabilities);

        String webSite = "http://www.cbsnews.com/";
        driver.get(webSite);

    } catch (Exception e) { }

    finally {
        driver.quit();  
    }

}

}

Thanks, Robins

[Candide7]
