sh ‘runscript /test.suite/Script/test.script’

it turns out error, that says:  
Uncaught exception NSWindowServerCommunicationException, reason: Unable to connect to X Server ‘:0.0’

hope you can help.  
Thank you

Out of curiosity, how is your Jenkins agent launched (systemd service, SSH, or Java Web Start)? Is it a pipeline job or a freestyle project?

I experimented briefly with a headless Jenkins implementation on an Ubuntu server (I was also running Eggplant Functional on an Ubuntu workstation). I no longer use Jenkins but still enjoy EPF on Ubuntu LTS.

Was your question ever answered? If I had to guess, this is related to running on a headless implementation with no GUI processes running. I tried Xvfb (Virtual Framebuffer) and installing X Server (enabling X11 Forwarding in my SSH configuration).

Ultimately the framework did not fit my organization’s needs, so I never went further. Would love to hear what the resolution on your end was as I feel implementation of Eggplant products on GNU/Linux systems should definitely be ubiquitous and fixes for issues like these easily applied!

Hello,

There’s no X server at `:0.0 `run it with a virtual display

xvfb-run -a sh runscript /test.suite/Script/test.script

Or set DISPLAY only if a real desktop session exists.

Now that I’m starting to test out Eggdrive and command-line use, I discovered `libgnustep-headless`.

```auto
runscript ~/Documents/Scripts/test.script -GSBackend libgnustep-headless

```
