While we could put in a dummy test class, the nature of the javafx.swing module is that unit tests are unlikely to be useful (which is why the one test that was there was moved to the system tests area with all the other Swing interop tests).

I think I understand now why you didn't see the error. You had an empty folder, for some reason, that made Eclipse satisfied with the classpath file entry. The folder does not exist in the repo, so I expect anyone who clones it to get an error for a missing folder. This is why I removed it in my branch.
