When jfxrt.jar is finally placed on the default Java boot classpath (maybe jdk8), then the extra classpath configuration of it will (finally) no longer be necessary.
javac -classpath "C:\Program Files (x86)\Java\jdk1.7.0_09\jre\lib\jfxrt.jar" <test case java file> java -classpath "C:\Program Files (x86)\Java\jdk1.7.0_09\jre\lib\jfxrt.jar;." junit.textui.TestRunner <test case class>
But you're using a beta version of netbeans and java 8. I would like to use java 7 and netbeans.Although I was using a beta netbeans and java8, the features I used are also present in java 7 and NetBeans 7.2 and the instructions apply equally. I installed jdk7u9 and NetBeans 7.2.1 and everything worked just the same as it did when I used NetBeans 7.3beta + jdk8b65.
