Qualitia supports headless executions on Linux. In this mode, executions are possible with PC without display, keyboard, and mouse. Such executions are known to be faster as compared to headful executions. There are multiple configurations and allied software components that are required to support executions in headless mode. In order to execute test cases in headless mode, you need to configure the headless box by installing X Virtual FrameBuffer (Xvfb).

To install Xvfb, enter the following command at command prompt;:
sudo apt-get install xvfb
Xvfb uses the unique display number to run the operations graphically. Decide any number and turn the access control off entering the following command:
sudoXvfbsudo Xvfb :99 -ac
Once this is done successfully, change the properties in the qualitia.properties file as mentioned below.
...
Xvfb :99&
export DISPLAY=:99
java –jar qualitiaqualitiaoffline-offline-xxxx.jar
