[JUnit 4, Ant 1.7] assertEquals et assertTrue undefined

[Celinio Fernandes]

Hi,
my environment:
Junit 4.0
Ant 1.7
Eclipse 3.3
Java 1.5

I am trying to run a JUnit test with Eclipse 3.3 (Europa) but I have a small compilation problem:

  
package entity;
 
import java.util.List;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.Persistence;
 
import org.apache.log4j.BasicConfigurator;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
 
public class PersonTest {

private final Person p1 = new Person("Brett", 'L', "Schuchert", "Street1",
            "Street2", "City", "State", "Zip");
 
    private EntityManagerFactory emf;
    private EntityManager em;
 
    @Before
    public void initEmfAndEm() {
        BasicConfigurator.configure();
 
 
        emf = Persistence.createEntityManagerFactory("examplePersistenceUnit");
        em = emf.createEntityManager();
    }
 
    @After
    public void cleanup() {
        em.close();
    }
 
    @SuppressWarnings("unchecked")
    @Test 
    public void insertAndRetrieve() {
        em.getTransaction().begin();
        em.persist(p1);
        em.persist(p2);
        em.getTransaction().commit();
 
        final List<Person> list = em.createQuery("select p from Person p")
                .getResultList();
 
        assertEquals(2, list.size());
        for (Person current : list) {
            final String firstName = current.getFirstName();
            assertTrue(firstName.equals("Brett") || firstName.equals("FirstName"));
        }
    }
}
 

==>
The method assertEquals(int, int) is undefined for the type PersonTest
and
The method assertTrue(boolean) is undefined for the type PersonTest

If I import junit.framework.TestCase and extend TestCase :

public class PersonTest extends TestCase {

then it compiles but then I am not using JUnit 4.
And anyways the test fails because it complains that it does not find test methods ...

Is there a compatibility problem in the versions I use ?
(with ant, eclipse, junit ...)

Thanks in advance for your help.

For a junit 3 test, you need to configure the launch configuration.

For junit 4, simply statically import the assert methods:

import static org.junit.Assert.*;

thanks, that works.
I was not aware of this new feature of JS2E 1.5
Static imports seem a bit inappropriate to me, i am not sure this is a good thing.
It can make the code less readable, for example it is harder to see in which class a constant is defined, especially with the use of the wildcard in static imports, also called en masse imports.

Not harder than with implementing an interface where the constant is defined, which was common practice before Java 5 - and which was arguably even more inappropriate.

I find it to be a convenient feature, although it certainly can be misused. Which feature can't?
