The following toy example tests a few situations (some fail, to illustrate all cases).
<java5>
 import junit.framework.*;
 import java.util.ArrayList;
 
 public class HelloWorld3 extends TestCase {
 
  public void testMultiplication() {
    // Testing if 3*2=6:
    assertEquals("Multiplication", 6, 3*2);
  }
 
  public void testCreativeMultiplication() {
    // Testing if 3*2=6:
    assertEquals("Creative multiplication", 7, 3*2);
  }
 
  public void testException1() {
    try {
      ArrayList<Object> emptyList = new ArrayList<Object>();
      Object o = emptyList.get(0);   // throws IndexOutOfBoundsException
      fail("no exception");
    }
    catch (Exception e) {
    }
  }
 
  public void testException2() {
    try {
      int i = 0;
    }
    catch (Exception e) {
      fail("exception");
    }
  }
 
 }
</java5>
