JUnit4 in Eclipse

Question

I am trying to run some JUnit test modules in Eclipse 3.5, but to no avail.

JUnit3 is working fine.

When I create the JUnit4 testing module, Eclipse suggests adding the JUnit library to the classpath. I accept, but when I check to see if it has been added to the project properties panel, I see that JUnit4 has been added, but JARS is where it was included.
If I select Change , the message " JUnit 4 " appears in the line and just below " Current location: not found ."

When I run the JUnit4 test, I get an error message and an internal NullPointerException error occurs .

I read for about two days, and all the links say that the eclipse includes JUnit4, but it seems like I'm missing something.

I tried unsuccessfully to recreate my projects and create a test in new ones.

package test;

import static org.junit.Assert.*;

import org.junit.Test;

public class AuthServiceTest {

    @Test
    public final void testValidateCredentials() {
        fail("Not yet implemented"); // TODO
    }

}

[edit]

I added junit-4.8.1.jar to the project classpath and eclipse classpath, but the problem is still the same.

[Edit2]

I also added junit-dep-4.8.1.jar, since I'm not sure if these dependencies are needed, but without changes.

Answer 1

It seems that Eclipse 3.5 from the Fedora repository does not include JUnit, and installing the corresponding package also does not include it.
Another Debian computer presented the same problem. A clean download from eclipse.org solved the problem.

I will talk about this error at some point :)

Answer 2

.

Built Path--> Add Libraries

(JUnit 4 ).

Answer 3

My Eclipse installation provides JUnit 4, in the plugins \ org.junit4_4.3.1 \ junit.jar

If you cannot find it, I think you may need to download it.

You can associate your JUnit with the Eclipse JUnit settings in

Windows->Preferences->Java->Build Path->User Libraries

Select JUnit and you can add and edit the JAR.
