First, I'd like to welcome you, we are open to others getting involved, read up and familiar with the best practices and approaches we've worked out for the math project.
http://jakarta.apache.org/commons/math/developers.html http://jakarta.apache.org/commons/math/tasks.html
Three tools will be very advantageous for you to start working with in this regard
1.) Maven --> Is used to manage the entire project. JUnit tests get exec'd when most build goals ate executed within it. %maven test or %maven -Dtestcase=org.foo.bar.MyTest test:single-test
2.) Eclipse --> I think most of us used it for development. Anyways, you can run the ant build directly within it. Theres an entire gui environment for junit testing within eclipse.
3.) Ant --> the build.xml file in the math cvs is used for our nightly builds, it contains scripting that will actually run all the tests for you. %ant test
All of these have the ability to run JUnit tests either individually or all at once, out of the box.
Cheers, Mark

I emailed a few weeks ago about getting involved with Commons Math. One suggestion was to look at some of the tests. I have never used JUnit, and it's a bit hard to run tests that I don't understand when I am testing something else that I do not understand.
Anyway, I looked up some JUnit documentation and wrote a class that runs the tests in org.apache.commons.math.special.BetaTest. I just wanted some confirmation that I am able to run some of these tests properly. I included the output and the code below.
Am I correct in assuming that when the output is "Time: 0.001 OK (17 tests) Test failures: 0" that all the tests ran correctly? The pages I found used the JUnit GUI for output. They really don't talk much about the text output at junit.org.
