Ubuntu Build is stuck on test phase

I am creating a Javafx application which opens and closes windows during my tests. I am testing on Windows, Mac and Ubuntu and the build completes fine on windows and mac but always gets stuck on the first test until I have to cancel it or it stays like that for an hour and fails.

You can see one of my builds here: https://ci.appveyor.com/project/Marcsllite/rad-shipment-calc/builds...

I have tried running the tests on different Ubuntu images, removing the first test file to see if it was related to that, and adding export DISPLAY=:99.0 like I had to for my travis builds. I looked through the discussions and couldn't find any that helped me. I believe this has something to do with needing a gui for the tests but I am not sure. Any assistance would be greatly appreciated.

    It could be Build Agent crashes on Ubuntu, for some reason. Try enabling SSH to the build worker and then check build agent logs:

    journalctl -u appveyor-build-agent -n 100

    It looks like the build agent doesn't show that it crashed. I think it's a maven issue.

    I looked into maven test freezing and followed this guide i found which showed me that this is all caused by JavaFX waiting for the start of the fx thread.

    I updated my tests to use junit 5 and started using xvfb for the display
    Xvfb :99 & export DISPLAY=:99 and everything is working fine. Thanks for the assistance
