Hi again,
I have some updates about the JUnit testing from below.
After some searching, and talking to someone who works closely with JUnit, I've found that I can not export an XML report directly from a JUnit call. Instead I have to call ant and export it from there.
This gives me 2 questions:
1) In order to write this I would have to invoke ant with a premade ant file which takes as arguments the classes to test. This itself is not hard, but does this sound like a good solution? I would just have to add an ant build file to a known directory.
2) If I write this and create a patch, is it ok to add ant to the dependencies list for ros, or just for rosjava, or where would this go? Which leads to should this be written in the rosjava CMake file, or in the main public / private cmake files in rosbuild?
I also, probably, will need help eventually with the CMake files, but I'll try them on my own first. I simply have never written CMake, before I started using ROS.
Thanks again,

I'll take a look at how to add Java JUnit testing to the rosbuild cmake files first. Whether I get it to work or not, I'll let you know how it goes.
As for rostest, I had seen this, but I noticed that it is for C++ and Python only. Once I get CMake JUnit testing to work the rostest should be fairly straight forward.

I don't know enough about Eclipse to give a recommendation there, but
there are two ways that you can test your code at the command-line:
(1) Use rostest (http://www.ros.org/wiki/rostest). It allows you to
bring up a ROS network, then use a program to run tests against that
network.
(2) Write standalone unit tests. The ROS build system has support for
running C/C++ (gtest) and Python (pyunit) tests. We don't yet have
support for Java, which I guess would use JUnit. It should be easy to
add support. Look in rosbuild/public.cmake and rosbuild/private.cmake
for how it's done for the other languages. Essentially, you need to
know the command-line that's required to invoke your compiled test
program, including redirection of test results to a particular
location. I can help with the CMake integration if you want.
Note that, for (1), if you want to write the test program itself in
Java, then you'll also need the new JUnit support described in (2)
(you could write test programs in Python or C++ using the current
infrastructure).
