Two exciting new plug-ins are now available in Fedora, a TestNG integration plug-in and the PHP Development Tools (PDT) plug-in.
The TestNG plug-in offers integration for Java projects using TestNG as an alternative to the Junit testing framework. It allows authoring, running and debugging TestNG tests in a similar way to the way you can with Junit tests.
$ sudo yum install eclipse-testng
The PHP Development Tools (PDT) plug-in attempts to provide a complete PHP IDE. I am not a PHP programmer so I can't tell you much about it, but at over two hundred thousand downloads from eclipse.org for this version alone, it seems pretty popular. It was added to Fedora as a maintainable replacement for the retired PHPEclipse plug-in, so if you were using that in the past please give this a try.
$ sudo yum install eclipse-pdt
