JavaFX on headless Jenkins

[Kevin Rushforth]

The headless toolkit mentioned by David and Richard is one possible 
approach, and may be the best long term approach depending on what you 
are trying to test (e.g., it won't test rendering, but might be fine for 
most of your tests), but as Richard notes, it isn't there yet.

If you prefer not to wait for that, one possible solution would be to 
set up a Jenkinks slave to be headful (may need to be hooked up to a 
keyboard/mouse or a display). You could then take a look at the system 
tests in rt/tests/system for examples of how we run headful tests. I 
don't know how feasible this would be for you.

Still another option is to use the oft-maligned StubToolkit (it stubs 
out all of Quantum and Prism), which all of our tests in the graphics 
and controls modules in JavaFX use. This isn't distributed (see 
https://javafx-jira.kenai.com/browse/RT-35010), but can easily be built 
from source.

However for running scene graph or UI control tests, you should be using the “StubToolkit” instead of QuantumToolkit. The StubToolkit is located in Graphics/src/test, so for using it for 3rd party tests (like JFXtras) you would need to jar up the classes produced during a test run of FX. Then just specify the stub toolkit via -Djavafx.toolkit=com.sun.javafx.pgstub.StubToolkit
