Selenium Chrome Driver

[andrew]

I am having problems with the Selenium chrome driver on my build pc.
I am getting periodic failures. When I look at the screen of the
build pc I see a chrome window opened with an empty tab. The url is
set to about:blank. The associated chrome driver log file is

Any suggestions on why this is happening?

[Adrian Longley]

Hi,

I am running the latest chromedriver.exe and WebDriver 2.20 and getting the following problem:

All my tests run well, but when I call Quit() on the ChromeDriver once a test is complete, Chrome itself closes, but chromedriver.exe does not.

So after 10 tests have completed I have zero browsers open but 10 chromedriver.exe processes left hanging.

Strikes me this is WebDriver's problem rather than chromedriver itself, but apologies if I'm wrong there. Anyone else seen this? Is this a known issue or am I doing something stupid?

Cheers,
Adrian

[Adrian Longley]

A bit more info. While there was nothing in the chromedriver.log I have just noticed this output from chromedriver.exe as the browser window closes:

[0306/153144:ERROR:automation_proxy.cc(387)] Channel error in AutomationProxy.

Ideas anyone?

Also, I am running on Windows via c#.

[Adrian Longley]

> Is this a known issue or am I doing something stupid?

Never mind, it was the latter!

Hi Adrian ,

I am also facing the same issue , In my Task Manager so many chromedriver.exe are running but test cases are pass.

I knw it silly but can anyone recommend after all test complete i should use webdriver.quit or webdriver.close.


Thanks

[Mike Riley]

The quit() method should close all open windows for a session, where close() will only close the current on, I believe.  I always use quit().

Mike

[Brian George]

I'm curious what you found you were doing incorrectly?

Brian

[darrell]

I know that if I abort a test and close the Chrome browser in the middle of the test, the chromedriver.exe associated with it remains open. So it is necessary for the WebDriver code to send the driver.quit() signal in order to have the chromedriver.exe exit memory.

This smells like something in your test is failing in maybe the setup. Most frameworks will have a setup, test, teardown structure. If the test dies in the middle of the 'test' section it will call the teardown. The teardown will close the browser and thus close the chromedriver.exe.

Maybe you have two conditions causing this error. The first would be that the code would die in the setup but after it opened the initial browser window (before the driver.get()). The second is that the teardown code assumes too much. If the setup fails it will jump right to the teardown. If the teardown assumes the setup ran to completion it might be trying to do something which also fails. If the teardown fails before it gets to the driver.quit() then there is nothing to close the browser. Thus you have a browser with a blank tab and a chromedriver.exe running in the background.

Also, I notice a lot of switches in the launching chrome INFO. Are those the default? If no, maybe turn a few off. That might change things. Maybe give you better/different error messages.

Darrell

[darrell]

Mani,

If you driver.close() it will close the current window but might leave the chromedriver.exe running. I always driver.quit() at the end of a test suite, so it will close the chromedriver.exe.
