Execution cannot find 'org.junit.Assert' even if you have the Junit jar in classpath

I have a problem that I’ve done a lot of research on and I haven’t found the answer to yet. I have a test case I’m trying to run and send a message to the console. But even though he has Junit’s jars, he still accuses them as if he can’t find them. I have a Maven project set up with spring in my eclipse, and I have already added the Junit library to the classpath. I manually added it by going to Build Path, and I also put the dependency on POM. Inside Maven dependencies has another jar of Junit, version 3.8.1.

I thought it was version conflict between the version specified in the POM (It’s 3.8.1) and the one I manually added (4). But that’s not it. I already tried to put version 4 in the POM and it didn’t work, I tried to leave only the one I put manual, or only the dependency one and it didn’t work either. And I have another minor project, also Maven but spring-less which is working normally, with the same jars as Junit. 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’s jars aren’t added, but they are. Does anyone know how to solve this problem?

The test class I had 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!"; 



    }



}

java web-application spring maven junit

  • What happens if you run mvn test?

  • Post your pom.xml

  • @Leonardovillela, I posted the pom

  • This test file is in the src/test/java directory?

  • I was able to help?

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

  1. mvn clean
  2. mvn install

Follow in gist, why I could not format here: https://gist.github.com/anonymous/3e25788a35c8890a14c9363444a1bd63

Follow the test class:

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);
        }
    }
}

  • Hello, Leonardo. Thank you, but unfortunately it didn’t work. Keep giving the same error

  • You replaced your pom by the one I put in the gist? why did my machine work perfectly.

  • Yes, I replaced the pom, and kept making the same mistake. But I found a solution in Stackoverflow in English. Thanks for the help, anyway
