Failed to create browser instance for Selenium Node running in background #942

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Issue Description:

When launching Selenium node with chromedriver by Windows Task Scheduler, 
Selenium node fails to create a instance of Chrome browser on request. Selenium 
node and hub are running in background on behalf of my user (I can see their 
processes runnings with Task Manager). By background I mean that I cannot log 
into their Windows session, so for instance I cannot see their command line 
windows nor the moment when browsers' windows are instantiated.

When I launch Selenium node and hub manually, there is no such problem with 
creating Chrome browser instance.

Also, I do not have such problems with creating instances of Internet Explorer 
and FireFox, when Selenium node runs in background.

Steps to reproduce:

1. Schedule task with Windows Task Scheduler to launch Selenium Hub and Node 
just after Windows OS starts

2. Request creation of Selenium Web Driver.

      DesiredCapabilities capabilities = new DesiredCapabilities();
      capabilities.setCapability("chrome.switches", "--verbose");
      WebDriver driver = new RemoteWebDriver(hubUrl, DesiredCapabilities.chrome().merge(capabilities));

3. Expect driver instance to be created.

-----Other helpful tips:

* Chrome Version 38.0.2125.104 m
* chromedriver.exe Version 2.11
* Selenium Hub/Node in Java, Version 2.43.1

Hello,
This issue has appeared on our environment as well since 15th October. It seems 
that the problem is related to the new Chrome version.

The issue is reproducible with the following chromedriver versions - 7 / 8 / 9 
/ 10 /11. I haven`t tried with the ones before 7.

I have tried with the latest Chrome Beta version (39....) and the issue is 
reproducible as well.

Selenium Hub / Nodes are setup as a windows service. The following guide was 
followed - 
http://brantleytec.blogspot.com/2012/11/selenium-hub-and-node-as-windows-service
.html. 

Workaround - stop the service / create autologin / add a bat script which will 
start the selenium node on startup.

Hello and thanks for your feedback.

I'm not running Selenium Hub / Nodes as a windows service, but as a task 
scheduled by Windows Task Scheduler with option "run whether user is logged in 
or not" checked up. I guess, still, the root cause is the same: in both cases 
it tries to run Chrome in non-interactive way. And it fails.

I cannot turn on autologin because in my Windows 7 Enterprise there is no such 
option for security reasons (the machine is on a domain): 
http://answers.microsoft.com/en-us/windows/forum/windows_7-security/windows-7-au
to-login-without-the-users-must-enter/d8a23f48-6333-4def-9d5c-8dae444f8093

The workaround I found is to register a task to be scheduled on user logon (not 
on system startup) and check up the "run when user is logged in" option. This 
is far from perfect because it requires an additional manual step (log in) each 
time a machine is restarted but it works.

Hello,

Today I got latest version of Chrome exe V 2.12 and Standalone server 2.44, and 
we started facing same issue. Everything works when we run Standalone Hub and 
Node manually but when we run them using task scheduler then nothing works.

Please update if someone found solution related to this issue.

Hello, 
I am also facing the same issue, when I try to run my Selenium tests from the 
task scheduler. It works perfectly fine when I run them manually. Can any one 
suggest a older version of chrome that might work.. ?

Thanks,
Barkha

Hi all,

I'm experiencing the exact same issues!

Successful:
- Executed Selenium node manually (node command process in foreground)
- Run parallel tests in Chrome
- All tests run without issues

Fail:
- Executed Selenium node remotely (node command process in BACKGROUND)
- Run parallel tests in Chrome
- Tests hang and then eventually fail
- HOWEVER
- This only happens when I try to run more than TWO tests in parallel
- If I run 1 or 2 tests in parallel, the tests execute without any issues
- If I so much as run 3 tests in parallel, the tests hang and fail...

Bit of a frustrating issue, this...
Any ideas or temporary workarounds?

Thanks,
Nathan

issue looks similar to 
https://code.google.com/p/chromium/issues/detail?id=422218#c39.
This issue is not reproducible with latest chrome version '41.0.2272.89'.

please try with latest version and let us know if we differ from what you are 
doing.
