This tutorial will walk you through basic steps to run Katalon Studio’s web UI tests using our plugin for Jenkins on a headless Ubuntu machine i.e. a machine without any display.
If you are interested in using Docker images instead, please see https://github.com/katalon-studio-samples/ci-samples.
If you are using Windows or macOS we will have similar tutorials soon.
Please follow official instructions by Jenkins.
Install Google Chrome
wget -O google-chrome-stable_current_amd64.deb https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo dpkg -i google-chrome-stable_current_amd64.deb sudo apt -y -f install
Xvfb or X virtual framebuffer is a display server implementing the X11 display server protocol. In contrast to other display servers, Xvfb performs all graphical operations in virtual memory without showing any screen output. From the point of view of the client, it acts exactly like any other X display server, serving requests and sending events and errors as appropriate. However, no output is shown. This virtual server does not require the computer it is running on to have any kind of graphics adapter, a screen or any input device. Only a network layer is necessary.
sudo apt install -y xvfb
Install Katalon plugin for Jenkins
Go to Manage Jenkins > Manage Plugins > Available and find Katalon plugin on the list.
Create and configure a new Jenkins project
To keep it simple, I will use Freestyle project.
The sample Katalon Studio project can be cloned from Github.
Next, add and configure the build step Execute Katalon Studio tests provided by Katalon plugin for Jenkins.
- Katalon Studio will be downloaded and installed automatically based on the version you specify.
- Please leave out
-runModein the arguments list.
- If you want to learn more about
xvfb-runconfiguration please see its manual. If you are not sure, only change the resolution
1024x768x24and leave other options as-is.
If for some network conditions the Katalon Studio package cannot be downloaded, you can install it manually and specify its location.
me@ubuntu:~$ sudo su root@ubuntu:~$ su jenkins jenkins@ubuntu:~$ wget https://github.com/katalon-studio/katalon-studio/releases/download/v5.10.1/Katalon_Studio_Linux_64-5.10.1.tar.gz jenkins@ubuntu:~$ tar -xzf Katalon_Studio_Linux_64-5.10.1.tar.gz jenkins@ubuntu:~$ cd Katalon_Studio_Linux_64-5.10.1 && pwd
The last command will print the location you need (
Run, Katalon, run!
Go to the Jenkins project page (e.g. at http://localhost:8060/jenkins/job/test/ if its name is “test”), click Build Now.
After it finished, you can find the report in the Last Successful Artifacts section.
- It’s quick and easy - you won’t even have to install Katalon Studio manually
- It works even on machines without displays.
- Allocating an isolated virtual display for each Jenkins build increases the stability of execution.
