Spring – No qualifying bean of type found for dependency

I´m tri to run a JUnit Test um my spring boot project i bilded like this:

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import com.br.suppcomm.ocp.entity.Login;


public interface LoginDao extends JpaRepository<Login, Long>{
...
}

Service:

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.br.suppcomm.ocp.dao.CompanyDAO;
import com.br.suppcomm.ocp.dao.LoginDao;
import com.br.suppcomm.ocp.entity.Login;



@Service
public class LoginService  {

    @Autowired LoginDao loginDao; 


    @Autowired CompanyDAO companyDao;


    public void save(Login login) {

        loginDao.save(login);


    }


    public void delete(Login login) {
         loginDao.delete(login);
    }


    public Login findById(Login login) {
        return loginDao.findOne(login.getLoginId());
    }


    public Login findByEmail(Login login) {
        return loginDao.findByEmail(login.getEmail());
    }


    public Login FindByLogin(Login login) {
        return loginDao.FindByLogin(login);
    }


    public List<Login> getAll() {

        return loginDao.findAll();
    }


    public Login getUserAccessLoginPass(String login, String password) {
        return loginDao.getUserAccessLoginPass(login, password);
    }


    public void update(Login login) {
         loginDao.save(login);

    }

}

Test:

package com.example;


import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import com.br.suppcomm.ocp.service.LoginService;


@RunWith(SpringRunner.class)

@SpringBootTest
public class OcpJpaApplicationTests {

    @Autowired LoginService loginService;

    @Test
    public void contextLoads() {


    }    

}

When I ran this code did show me the folow error.

Caused by: org.springframework.beans.factory.UnsatisfiedDependencyException:
