Try the following snippet (plain junit 3 based test):

import junit.framework.TestCase;

public class Asdf extends TestCase {


	public void testTimer() {
		long starttime= System.currentTimeMillis();
		try {
			Thread.sleep(2000);
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		assertTrue((System.currentTimeMillis()-starttime)>2000);

	}
}


Running it using a run configuration for junit 3 sometimes shows execution time below 2000 milliseconds what is always wrong. Junit 4 sometimes shows exactly 2000 milliseconds and Junit 5 shows always more than 2000 milliseconds what seems to be OK.
