I have a problem that I have researched a lot and still have not found the answer. I have a test case that I'm trying to run and send a message to the console. But even with JUnit jars, he accuses them as if he did not find them. I'm having a maven project set up with spring in my eclipse, and I've added the JUnit library to the classpath. I added manually going to the Build Path, and also put the dependency on the POM. Within maven dependencies you have another JUnit jar, version 3.8.1.

I thought it was version conflict between the version specified in the POM (Is 3.8.1) and the one I added manually (4). But that's not it. I already tried to put version 4 in the POM and it did not work, I already tried to leave only the one I put manual, or just the one of the dependency and also did not work. And I have another smaller project, also maven but without spring that is working normally, with the same JUnit jars. When I try to run a test case, this is the error that comes to the console:

SEVERE: Servlet.service() for servlet [mvc-dispatcher] in context with path [/javaliproject] threw exception [Handler processing failed; nested exception is java.lang.NoClassDefFoundError: org/junit/Assert] with root cause

It's like JUnit jars are not added, but they are. Does anyone know how to solve this problem?

The test class I created was this:

import static org.junit.Assert.*;

import java.io.IOException;
import java.lang.reflect.InvocationTargetException;

import org.junit.Test;






public class Runner {
    @Test
    public static String runClass() throws ClassNotFoundException, InstantiationException, IllegalAccessException, IOException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException {

        int retornoEsperado = 9;
        int retornoFeito = 10;

        String assertionError = null;
        try {

            assertEquals(retornoEsperado, retornoFeito);
            System.out.println("O método está correto");
        }
        catch (AssertionError ae) {
            assertionError = ae.toString();
            System.out.println(assertionError);
        }

        return "Executou!"; 



    }



}

Hello, the first problem I see is that Junit's test methods must have the type of return void and the method can not be static, I've also modified your pom.xml to add the correct version of junit and the module of spring testing, you will probably need it, follow the pom.xml file, after adding it in your project run the following commands:

mvn clean

mvn install

Follow the gist, why can not I format it here: link

The test class follows:

import static junit.framework.Assert.assertEquals;

import java.io.IOException;
import java.lang.reflect.InvocationTargetException;

import org.junit.Test;

public class Runner {
    @Test
    public void runClass() throws ClassNotFoundException, InstantiationException, IllegalAccessException, IOException, NoSuchMethodException, SecurityException, IllegalArgumentException, InvocationTargetException {

        int retornoEsperado = 9;
        int retornoFeito = 10;

        String assertionError = null;
        try {

            assertEquals(retornoEsperado, retornoFeito);
            System.out.println("O método está correto");
        }
        catch (AssertionError ae) {
            assertionError = ae.toString();
            System.out.println(assertionError);
        }
    }
}

I found the solution in StackOverFlow in English. I just removed the JUnit dependency scope tag on my pom, where it had <scope>test</scope> . Follow the link for the answer: / a>
