It was easier than I thought

I wanted a way to distribute JUnit tests among multiple threads. I couldnt believe how easy it turned out to be.

 public class ParallelTestSuite extends TestSuite {
 private final int numWorkers;

 public ParallelTestSuite(int numWorkers) {
 this.numWorkers = numWorkers;
 }

 @Override public void run(TestResult result) {
 final ExecutorService executor
 = Executors.newFixedThreadPool(numWorkers);
 TestResult newResult = new ForwardingTestResult(result) {
 @Override protected void run(final TestCase test) {
 executor.execute(new Runnable() {
 public void run() {
 superRun(test);
 }
 });
 }
 private void superRun(TestCase test) {
 super.run(test);
 }
 };
 super.run(newResult);
 executor.shutdown();
 try {
 executor.awaitTermination(3600, TimeUnit.SECONDS);
 } catch (InterruptedException e) {
 }
 }
 }

ForwardingTestResult is just what it sounds like; a TestResult that forwards all its method calls to another TestResult.

I found it interesting that I couldnt really figure out how to avoid needing that one-line "superRun()" method. What else could I do?

Anyone out there who understands JUnit and java.util.concurrent have any helpful criticism for how to make this better?
