Purpose of SceneBuilderTest in production package?

[AlmasB]

It seems SceneBuilderTest is a manual system test as the IDE reports no usages of it in the production package of app. If so, would it make more sense to move this to the test package?

[Oliver-Loeffler]

As of now, I'd agree with moving it into the test source tree. There, it could be reworked to run as a JUnit test or we could even utilize TestFX to run it.
