Anybody have any luck using Jenkins Selenium Grid plugin with WebDriver to execute Chrome?

[bhill]

Hi,

I have a running instance of the Selenium Grid plugin running on Jenkins 
LTS 1.480.1.
* I've configured the grid to use a chrome browser:

> {seleniumProtocol=WebDriver, platform=LINUX, browserName=chrome, 
> maxInstances=5, jenkins.nodeName=CentOS 6 Java 7, version=24.0}


* I've installed the chromedriver on my remote machine at 
/usr/local/jenkins/tools/chrome/chromedriver 
* I've installed chrome on the remote machine at /usr/bin/google-chrome
* I used the Firefox Selenium IDE to create a test case and tweaked it a 
bit for RemoteWebDriver

Re: Re: CSS and Images Broken Post LTS 1.480.1 Update?

[bhill]

Hi,

I'm glad to be able to eliminate the view as a problem.  I originally 
installed Jenkins as a native package.  However, since then I have been 
upgrading by simply updating the .war file

Procedure I used:

   1.  /etc/init.d/jenkins stop
   2. cd /var/lib/jenkins
   3. jenkins.war /var/lib/jenkins/jenkins.war.bkp
   4. wget http://updates.jenkins-ci.org/download/war/1.480.1/jenkins.war
   5. /etc/init.d/jenkins start

This is where my system admin abilities are a bit under cooked.  Should I 
be upgrading via a package?  On the manage Jenkins page when I click on the 
update button I download the new .war, which is why I though it was the 
only thing needed for the update.  Please correct me if I'm wrong.

Thank you

Re: CSS and Images Broken Post LTS 1.480.1 Update?

[bhill]

Thank you for the response.

Vojta, I did as you asked and looked if I could load the css via browser by 
grabbing the link href source from the source code.  I was able to pull up 
the css file for both the style.css and color.css without problem via 
browser.

Here are some more specifics regarding this issue.

   - Jenkins is running LTS 1.480.1 on CentOS 5 using java 6
   - What I've tested
  - clear cache
  - Initial load (Not logged in)
 - Windows -> IE 9 (Broken css and images)
 - Windows -> FF 18 (Broken css and images)
 - Windows -> Chrome 64 (Broken css and images)
 - Apple -> Safari (Broken css and images)
  - Login
 - Windows -> IE (Working css and images)
 - Windows -> FF (Working css and images)
 - Windows -> Chrome (Broken css and working images)
 - Apple -> Safari (Working css and images)
  - Logout
 - Windows -> IE (Working css and broken images)
 - Windows -> FF (Working css and broken images)
 - Windows -> Chrome (Broken css and images)
 - Apple -> Safari (Broken css and images)
  
On the same thread, but a different note the only other change to our 
Jenkins installation around the same time I updated to the current Jenkins 
LTS release was changing the 'All' view.  I followed the directions located 
on the wiki 
at 
https://wiki.jenkins-ci.org/display/JENKINS/Editing+or+Replacing+the+All+View. 
 

I've noticed that when first loading the homepage the message has changed. 
 Prior to update it said (paraphrasing) "You are not logged in. Login now." 
 It now states "This view has no jobs associated with it."  Could this be 
part of my issue?  Is there a way to reset the 'All' view to it's default 
setting?  I'm curious if that is causing some permission issues with the 
view?  I wouldn't mind resting it to default it to try to isolate the issue 
I'm experiencing.

Thank you

CSS and Images Broken Post LTS 1.480.1 Update?

[bhill]

Hi,
I currently have an instance of Jenkins running the LTS 1.480.1.  I do have 
Jenkins managing the users who have access to the jobs.  After the update I 
noticed that logged out users have broken CSS.  Has anyone else had any 
issues with their CSS after the upgrade?  It is causing confusion among our 
engineers as the login links are white on white...

Is their a way I can fix the CSS on my end.  I don't want to do too much 
customization as I want to keep up with the LTS branch without worrying 
about breaking my customization.  I've noticed their is a plugin called the 
'Simple Theme Plugin' that may allow me to customize the CSS so they can 
see it, but again.  I want to keep it as out of the box as possible. 
 Please advise if this is something I can do or if this is a known issue. 
 I've searched around a bit, but have come up empty handed.  

Thank you,

P.S. Please see the attached image
