I found this example on Azure Pipelines repo. I only managed to get it working after I copied this piece of code and the file xvfb.init .

steps:
- script: |
    sudo cp .azure-pipelines/linux/xvfb.init /etc/init.d/xvfb
    sudo chmod +x /etc/init.d/xvfb
    sudo update-rc.d xvfb defaults
    sudo service xvfb start
  displayName: 'Start X Virtual Frame Buffer'

- script: |
    export DISPLAY=:10
    gulp test
  displayName: 'Test'
