SpringBootTest Service Test - MockitoAnnotations Giving NoSuchMethodError: openMocks (java.lang.AutoCloseable)

Question

I am new to JUnit4 / JUnit5 and Mockito springboot testing and I am doing a SpringBoot test on my REST service for my SpringBoot SpringMVC backend but I keep hitting a

java.lang.NoSuchMethodError: 'java.lang.AutoCloseable org.mockito.MockitoAnnotations.openMocks(java.lang.Object)'

error. I suspect I have a mismatch in my Mockito dependencies in my pom.xml file but I don't know how to go about fixing it and getting the test to work. Please help. (I would also like to see what changes need to be made to make the test work using JUnit4 and JUnit5 and what are the main differences).

Here is my UserServiceTest.java:

package com.fsgsm.kilosteprest.service;


import org.junit.jupiter.api.Test;

//import org.junit.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;

/*
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
*/

import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.mockito.junit.jupiter.MockitoExtension;

//import org.springframework.boot.test.context.SpringBootTest;
//import org.springframework.boot.test.mock.mockito.MockBean;

import org.springframework.test.context.junit.jupiter.SpringExtension;


import static org.junit.Assert.assertEquals;


import com.fsgsm.kilosteprest.model.User;
import com.fsgsm.kilosteprest.repository.UserRepository;


@ExtendWith(MockitoExtension.class)
@ExtendWith(SpringExtension.class)
public class UserServiceTest {
    
    /*
    @Autowired
    UserService userTestService;
    */
    
    
    @Mock
    UserRepository userRepository;

    
    @InjectMocks
    UserService userTestService;
    
    
    
    @Test
    public void testUserServiceCreation() {     
        
        
                User testUser = new User();
        
                
                testUser.setUserName("testdata");
                testUser.setUserRole("admin");
                testUser.setUserPassword("99999");
                testUser.setUserTelNo("99999");
                testUser.setUserEmail("test@test.com");
                
                Mockito.when(userRepository.save(testUser)).thenReturn(testUser);
                
                //Test if user saved in db
                assertEquals(1,userTestService.getUsersByUserName("testdata").size());

                userTestService.deleteUserByUserName("testdata");
                
        
    }

}

P.S. >> Note there is a similar post at: stackoverflow.com/questions/67432118/… which I tried the solution by excluding the required dependencies and upgrading my mockito-core to 3.11 but somehow the error persisted.

Perhaps this will help you: https://stackoverflow.com/questions/67432118/how-to-fix-this-error-java-lang-nosuchmethoderror-java-lang-autocloseable-org — Tarmo, Sep 01 '21 at 11:36
Thanks a lot Tarmo but I have already read this post before I posted mine and tried the recommended solution (as you can see from my pom file but the error didn't go away!) — Ezani, Sep 01 '21 at 11:38
Your dependencies are a mess. You are mixing different jars from different versions of a framework that will not work. You are trying to be smarter than the `spring-boot-starter-test` dependency which is now coming back to haunt you. Remove the exclusions from `spring-boot-starter-test` and remove the junit/mockito dependencies. Your test is also mixing JUnit4 and JUnit5 which will also bite you either use 4 or use 5, don't mix. Finally whats is with the `@Mock` on an `AutoClosable` what are you trying to do with that (and the manual init). — M. Deinum, Sep 01 '21 at 12:19
YOu also don't need the `MockitoAnnotations.init` in your code as that is done by the `MockitoExtension` already, so you are duplicating the work. — M. Deinum, Sep 01 '21 at 12:32
