I have a base unit test class:

@SpringBootTest
public abstract class BaseUnitTest {

    @BeforeEach
    public abstract void setupForEach();

    protected UserEntity createMockUser() {
        return Mockito.mock(UserEntity.class);
    }

    protected OrgEntity createMockOrganization() {
        return Mockito.mock(OrgEntity.class);
    }

    // other test helper methods

}

And a test class:

public class RegistrationServiceTest extends BaseUnitTest {

    @MockBean
    private UserService userService;

    @MockBean
    private OrgService orgService;

    @Autowired
    private RegistrationService registrationService;

    @Override
    public void setupForEach() {

    }

    @Test
    public void inviteUser_whenInputIsGood_thenUserIsCreatedAndInviteIsSent() {

        // setup
        UserEntity newUser = createMockUser();
        OrgEntity org = createMockOrganization();

        when(userService.getByEmail(eq("some email"), anyBoolean())).thenReturn(null);
        when(organizationService.getByRefId(anyString())).thenReturn(org);

        // test
        UserInvitationEntity result = registrationService.inviteUser(user);

        // check
        assertNotNull(result);

    }


}

When I run this test class I get the following exception:

Don’t worry about the coding/implementation of my test class/method, I’m curious as to why I’m getting this java.lang.NoSuchMethodError. I suspect its incompatible versions of Java, Spring Boot and JUnit but I can’t tell where I’m going wrong.
