I use new Eclipse. Create demo test with jUnit (I added default jUnit library built-in Eclipse). Then I write this code:

import junit.framework.*;

import org.junit.Test;

public class SimpleTest extends TestCase { 
   public SimpleTest(String name) { 
      super(name);
   }
   public final void main(String method){

   }

   @Test
   public final void testSimpleTest() {
      int answer = 2;
      assertEquals((1+1), answer); 
   }
}

But it doesn't run. In the Debug tab:

org.eclipse.jdt.internal.junit.runner.RemoteTestRunner at localhost:52754 
Thread [main] (Suspended (exception ClassNotFoundException)) 
URLClassLoader$1.run() line: not available [local variables unavailable] 
AccessController.doPrivileged(PrivilegedExceptionAction<T>, AccessControlContext) line: not available [native method] 
Launcher$AppClassLoader(URLClassLoader).findClass(String) line: not available 
Launcher$AppClassLoader(ClassLoader).loadClass(String, boolean) line: not available 
Launcher$AppClassLoader.loadClass(String, boolean) line: not available 
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available 

How can I solve this?
