Headless testing with JavaFx and TestFx

Question

I have a simple JavaFx application (Java 8) that has a unit test using TestFx. However, when the test is run, the application window starts up and the mouse is moved to do whatever action is in my test. Can these tests be run in a way where the application doesn't popup and I can still use my mouse for other things as the automated build and tests are running?

Answer 1

I would agree with KDK for using Monocle, since it does work as charm with Jenkins. I couldn't have reliable result from Xvfb on Jenkins. Below is the steps I took and works for me.

Prepare Monocle

You want to download Monocle from Monocle Github. It looks there is api change, so you would want to edit MonocleView.java with adding below method after download. I'm not sure what I should put in the method, but found it just works without implementing it.

@Override
protected int _getNativeFrameBuffer(long ptr) {
    // TODO Auto-generated method stub
    return 0;
}

Install Monocle

Build the Monocle jar and put the jar into your JRE (under jre/lib/ext path)

Run Monocle with Glass lib

Below is my maven command used in jenkins, you will have interest on java runtime option portion.

$ mvn clean install -Dtestfx.robot=glass -Dglass.platform=Monocle -Dmonocle.platform=Headless -Dprism.order=sw
