I have installed JUnit on my Ubuntu 11.04

sudo apt-get install junit

Then created a test file like:

import org.junit.*;



public class TestBasicLinkedList {

  @Test public void testCanAdd(String[] args) {

    BasicLinkedList<Integer> list = new BasicLinkedList();

    list.add(new BasicListNode<Integer>(1));

    assertTrue(list.size() == 1);

    assertTrue(list.getFirst().getElement().equals(1));

  }

}

Then tried running in terminal

java org.junit.runner.JUnitCore TestBasicLinkedList.java

Got:

Exception in thread "main" java.lang.NoClassDefFoundError: org/junit/runner/JUnitCore

Caused by: java.lang.ClassNotFoundException: org.junit.runner.JUnitCore

Could not find the main class: org.junit.runner.JUnitCore. Program will exit.

How do I use JUnit? Is there a better shorter way of using it than the long command java org.junit.runner.JUnitCore TestBasicLinkedList.java? Perhaps something like junit *.Tests.java maybe?
