Spring-boot: Unable to test custom repositories using Spring Boot Test

[jayaprakash-altimetrik]

I am using Spring Boot 1.4.4. Followed the Spring Boot Test article for unit tests. When I have custom repositories, test is not working and fails with error UnsatisfiedDependencyException: Error creating bean with name 'com.jay.UserRepositoryTest': Unsatisfied dependency expressed through field 'userRepository';

Here is my code,

@Repository
@Transactional
public class UserRepository  {

  @Autowired
  private EntityManager entityManager;

  // sample code for custom repo. can be done easily in CrudRepo
  public User findUser(String name){

    TypedQuery<User> q = entityManager.createQuery("Select u from User u Where u.name = :name", User.class);
    q.setParameter("name", name);

    return q.getSingleResult();
  }
}

@RunWith(SpringRunner.class)
@DataJpaTest
public class UserRepositoryTest {

  @Autowired
  private TestEntityManager entityManager;

  @Autowired
  private UserRepository userRepository;

  @Test
  public void findUserTest(){
    ...
  }
}

But I am able to test the following Dao with Spring Boot without any config change,

@Transactional
public interface UserDao extends CrudRepository<User, Long> {

  User findByEmail(String email);
}

When I am using @SpringBootTest, I am able to inject UserRepository, but not TestEntityManager.

As described in the documentation, @DataJpaTest will "configure Spring Data JPA repositories". Your UserRepository isn't a Spring Data JPA repository so it isn't configured.

In the same section of the documentation it also explains that if you want to use TestEntityManager with @SpringBootTest, you can enable it by adding @AutoConfigureTestEntityManager to your test class.
