How to run test cases in a jar file using junit?

Question

Hi,
I want to run test cases in a jar file using junit and the jar file is not in the class path. I wrote the following code, but it does not work.
import java.net.URL;
import java.net.URLClassLoader;
import junit.framework.TestResult;
import junit.textui.TestRunner;
public class MyTestRunner {
     public static void main(String[] args) throws Exception{
          URL url = new URL("file:///d:/case.jar");
          URLClassLoader loader = new URLClassLoader(new URL[]{url});
          loader.loadClass("TestCase1");
          TestRunner runner = new TestRunner();
          TestResult result = runner.start(new String[]{"TestCase1"});
          System.out.println(result.toString());
}Any ideas?
Thanks a lot.

Wouldn't it just be easier to put it on the classpath? You're trying to, anyway, with a URLClassLoader, albeit in an entirely unnecessarily complicated way
