write junit test in groovy script...

Hi there,

I have the following piece of code which is a junit test class to test a web page:

import junit.framework.*;
import com.thoughtworks.selenium.*;
import junit.textui.TestRunner;

public class Temp extends TestCase {
    private Selenium browser;
   
    public Temp(String name) {
    super(name);
    }
   
    public void setUp() {
        //some code
    }
   
    public static TestSuite suite() {
    return new TestSuite(Temp.class);
    }
   
    public void test1(){
        // some code
}
    public void tearDown() {
        // some code
    }
   
    public static void main(String[] args){
        Temp test = new Temp("test");
    TestRunner a = new TestRunner();
    TestResult result = a.run(test.suite());
    }
}

This works fine in eclipse but in groovy i get the error :

groovy.lang.GroovyRuntimeException: Failed to create Script instance for class: class Temp. Reason: java.lang.InstantiationException: Temp

why can't i instantiate the Temp class in groovy?
Any idea on how to work around this?

thanks,
