It complained about "no tests found". I discovered that JUnit 4 was not on the build path, and I couldn't add it because while Eclipse had an entry in its Build Path -> Libraries -> Add Libraray -> JUnit -> JUnit 4, it just said "Not Found" and that was it. Adding it as an external JAR helped with the compiling but didn't enable the test runners either. <br /> <br /> It turned out that this was actually a <a href="https://bugzilla.redhat.com/show_bug.cgi?id=601059">packaging bug</a> in the Eclipse packages in Fedora 12 and that you have to also install the eclipse-pde package.<br /> I found the solution on <a href="http://forums.fedoraforum.org/showthread.php?t=240886">this thread in the Fedora forums</a>
